Our previous studies demonstrated that MEG3 was significantly downregulated in neuroblastoma (NB) and its expression was neg. associated with the INSS stage. Overexpression of MEG3 promoted apoptosis and inhibited proliferation in NB cells. In this study, we discovered more potential functions and mol. mechanisms of MEG3 in NB. According to the database, MEG3 pos. correlated with the NB survival rate and was neg. associated with malignant clin. features. Moreover, we determined that MEG3 was mainly located in the nucleus by nuclear-cytoplasmic separation and RNA fish assays. Upregulation of MEG3 in stably transfected cell lines was accomplished, and CCK8, colony formation, and EDU assays were performed, which indicated that MEG3 significantly suppressed cell proliferation. Both wound healing and transwell experiments demonstrated that MEG3 decreased cell migration and invasion. CHIRP enrichments showed the anticancer effects of MEG3 were probably linked to autophagy and the mTOR signaling pathway. LC3 fluorescence dots and western blots showed that MEG3 attenuated autophagy by inhibiting FOXO1, but not the mTOR signaling pathway. Furthermore, MEG3 inhibited metastasis through epithelial-mesenchymal transition via the mTOR signaling pathway. Consistent with the above results, downregulation of MEG3 facilitated NB malignant phenotypes. Mechanistically, MEG3 and EZH2 regulated each other via a neg. feedback loop and promoted NB progression together. In conclusion, our findings suggested that MEG3 was a tumor suppressor in NB and could be a potential target for NB treatment in the future. This study involved multiple reactions and reactants, such as 2-(2-Imino-4,5,6,7-tetrahydrobenzothiazol-3-yl)-1-p-tolylethanone Hydrobromide (cas: 63208-82-2Computed Properties of C16H19BrN2OS).

Long noncoding RNA H19 prevents neurogenesis in ischemic stroke through p53/Notch1 pathway was written by Wang, Jue;Cao, Bin;Zhao, Haiping;Gao, Yan;Luo, Yumin;Chen, Yuhua;Feng, Juan. And the article was included in Brain Research Bulletin in 2019.Reference of 63208-82-2 The following contents are mentioned in the article:

Long non-coding RNA H19 (H19) is one of the earliest discovered long non-coding RNAs. H19 induced the onset of ischemic stroke through regulating neuronal autophagy and microglial polarization. And we aimed to study whether H19 participated the neurogenesis process after ischemic stroke. Circulating H19 levels in ischemic stroke patients and the mRNA levels of p53 target genes were tested by real-time polymerase chain reaction. H19 small interference RNA and pifithrin-α were used to inhibit H19 and p53 expression in the mice suffered middle cerebral artery occlusion, resp. The expression of neurogenesis related proteins was assessed by Immunofluorescence and Western blot. Circulating H19 levels were pos. associated with the National Institute of Health Stroke Scale Scores of the patients in 7d, 30d and 90d after stroke attack., H19 small interference RNA significantly decreased the volume of brain tissue loss at 14d after middle cerebral artery occlusion and reperfusion in mice and promoted the neurol. deficit recovery of the mice. It was confirmed by immunofluorescence that H19 knockdown could decrease the fluorescence intensity of neurogenesis related proteins. While inhibiting p53 on the basis of H19 knockdown reversed the pro-neurogenesis effect of H19 inhibition. Furthermore, H19 decreased the transcriptional activity of p53 and the expression of Notch1, and p53 inhibition abolished these effects of H19. Our findings demonstrate that H19 prevents the process of neurogenesis after ischemic stroke through p53/Notch1 pathway and strengthen the novel role of H19-based therapy for ischemic stroke.

Active Targeting Nanoparticle Self-Assembled from Cisplatin-Palbociclib Amphiphiles Ensures Optimal Drug Ratio for Combinatorial Chemotherapy was written by Xiang, Yucheng;Liu, Chendong;Chen, Liqiang;Li, Lian;Huang, Yuan. And the article was included in Advanced Therapeutics (Weinheim, Germany) in 2021.Recommanded Product: 3-(Benzo[d]thiazol-2-yl)-7-(diethylamino)-2H-chromen-2-one The following contents are mentioned in the article:

Triple neg. breast cancer (TNBC) not only exhibits aggressive progression and metastasis, but also responds to neither hormone therapy nor checkpoint blockade therapy. Thus, combinatorial chemotherapy is indispensable for TNBC treatment. However, due to the different pharmacokinetics of individual drugs and weak synergistic effects caused by random drug molar ratio in tumor, direct coadministration is far from satisfactory. Constructing a nanoscale drug delivery system with fixed drug molar ratios and maximum drug content is an urgent problem. Herein, an active targeting nanoparticle self-assembled from cisplatin-palbociclib amphiphiles with optimal drug ratio is reported. The combination of cisplatin and palbociclib at a molar ratio of 1:2 is found to have the best synergistic effect and is selected for follow-up studies. After conjugating two palbociclib mols. to one cisplatin mol., a fixed cisplatin/palbociclib (1:2) molar ratio is enabled and this amphiphilic conjugate can self-assemble into nanoparticles. A small amount of iRGD coupled 1,2-distearoyl-sn-glycero-3-phosphoethanolamine-N-polyethylene glycol-2000 (DSPE-PEG-iRGD) that further stabilizes the nanoparticle is introduced to fabricate the desired nanoparticle (iRGD-PCN) and endow active tumor-targeting ability. On an orthotopic TNBC mouse model, iRGD-PCN efficiently accumulates in tumors and inhibits tumor growth. Addnl., the formation of lung metastasis nodes is also significantly suppressed. In general, the active targeting nanoparticles self-assembled from cisplatin-palbociclib amphiphiles provide options for combinatorial chemotherapy. This study involved multiple reactions and reactants, such as 3-(Benzo[d]thiazol-2-yl)-7-(diethylamino)-2H-chromen-2-one (cas: 38215-36-0Recommanded Product: 3-(Benzo[d]thiazol-2-yl)-7-(diethylamino)-2H-chromen-2-one).

RVG-functionalized reduction sensitive micelles for the effective accumulation of doxorubicin in brain was written by Xu, Jiangkang;Yang, Xiaoye;Ji, Jianbo;Gao, Yuan;Qiu, Na;Xi, Yanwei;Liu, Anchang;Zhai, Guangxi. And the article was included in Journal of Nanobiotechnology in 2021.Reference of 38215-36-0 The following contents are mentioned in the article:

Glioblastoma is a lethal neoplasm with few effective therapy options. As a mainstay in the current treatment of glioma at present, chemotherapeutic agents usually show inadequate therapeutic efficiency due to their low blood brain barrier traversal and brain targeting, together with tumor multidrug resistance. Novel treatment strategies are thus urgently needed to improve chemotherapy outcomes. Here, we report that nanomedicines developed by functionalizing the neurotropic rabies virus-derived polypeptide, RVG, and loading reduction-sensitive nanomicelles (polymer and doxorubicin) enable a highly specific and efficacious drug accumulation in the brain. Interestingly, curcumin serves as the hydrophobic core of the polymer, while suppressing the major efflux proteins in doxorubicin-resistant glioma cells. Studies on doxorubicin-resistant rat glioma cells demonstrate that the RVG-modified micelles exhibit superior cell entry and antitumor activity. In vivo research further showed that RVG modified nanomicelles significantly enhanced brain accumulation and tumor inhibition rate in mice, leading to a higher survival rate with negligible systemic toxicity. Moreover, effective suppression of recurrence and pulmonary metastatic nodules were also determined after the RVG-modified nanomicelles treatment. The potential of RVG-modified nanomicelles for glioma was demonstrated. Brain accumulation was markedly enhanced after i.v. administration. This unique drug delivery nanoplatform to the brain provides a novel and powerful therapeutic strategy for the treatment of central nervous system disorders including glioma.

Poly (glycerol adipate) (PGA) backbone modifications with a library of functional diols: Chemical and physical effects was written by Jacob, Philippa L.;Ruiz Cantu, Laura A.;Pearce, Amanda K.;He, Yinfeng;Lentz, Joachim C.;Moore, Jonathan C.;Machado, Fabricio;Rivers, Geoffrey;Apebende, Edward;Fernandez, Maria Romero;Francolini, Iolanda;Wildman, Ricky;Howdle, Steven M.;Taresco, Vincenzo. And the article was included in Polymer in 2021.Application of 38215-36-0 The following contents are mentioned in the article:

Enzymically synthesized poly(glycerol adipate) (PGA) has shown a palette of key desirable properties required for a biomaterial to be considered a ′versatile polymeric tool′ in the field of drug delivery. PGA and its variations can self-assemble into nanoparticles (NPs) and interact at different levels with small active mols. PGA derivatives are usually obtained by functionalising the glyceryl side hydroxyl group present along the main polymer scaffold. However, if the synthetic pathways are not finely tuned, the self-assembling ability of these new polymeric modifications might be hampered by the poor amphiphilic balance. For this reason, we have designed a straightforward one-pot synthetic modification, using a small library of diols in combination with glycerol, aimed at altering the backbone of the polymer without affecting the hydrophilic glyceryl portion. The diols introduce addnl. functionality into the backbone of PGA alongside the secondary hydroxyl group already present. We have investigated how extra functionalities along the polymer backbone alter the final polymer reactivity as well the chem. and biol. properties of the nanoparticles. In addition, with the intent to further improve the green credentials of the enzymic synthesis, a solvent derived from renewable resources, (2-MeTHF) was employed for the synthesis of all the PGA-variants as a replacement for the more traditionally used and fossil-based THF. In vitro assays carried out to evaluate the potential of these novel materials for drug delivery applications demonstrated very low cytotoxicity characteristic against NIH 3T3 model cell line.

Genotoxic effects of 1-nitropyrene in macrophages are mediated through a p53-dependent pathway involving cytochrome c release, caspase activation, and PARP-1 cleavage was written by Wu, Sheng-Wen;Su, Chun-Hung;Ho, Yung-Chuan;Huang-Liu, Rosa;Tseng, Ching-Chi;Chiang, Yun-Wei;Yeh, Kun-Lin;Lee, Shiuan-Shinn;Chen, Wen-Ying;Chen, Chun-Jung;Li, Yi-Ching;Lee, Chien-Ying;Kuan, Yu-Hsiang. And the article was included in Ecotoxicology and Environmental Safety in 2021.Application of 63208-82-2 The following contents are mentioned in the article:

Genotoxic stress from environmental pollutants plays a critical role in cytotoxicity. The most abundant nitro-polycyclic aromatic hydrocarbon in environmental pollutants, 1-nitropyrene (1-NP), is generated during fossil fuel, diesel, and biomass combustion under sunlight. Macrophages, the key regulators of the innate immune system, provide the first line of defense against pathogens. The toxic effects of 1-NP on macrophages remain unclear. Through a lactate dehydrogenase assay, we measured the cytotoxicity induced by 1-NP. Our results revealed that 1-NP induced genotoxicity also named DNA damage, including micronucleus formation and DNA strand breaks, in a concentration-dependent manner. Furthermore, 1-NP induced p53 phosphorylation and nuclear accumulation; mitochondrial cytochrome c release; caspase-3 and -9 activation and cleavage; and poly (ADP-ribose) polymerase-1 (PARP-1) cleavage in a concentration-dependent manner. Pretreatment with the PARP inhibitor, 3-aminobenzamide, significantly reduced cytotoxicity, genotoxicity, and PARP-1 cleavage induced by 1-NP. Pretreatment with the caspase-3 inhibitor, z-DEVD-fmk, significantly reduced cytotoxicity, genotoxicity, PARP-1 cleavage, and caspase 3 activation induced by 1-NP. Pretreatment with the p53 inhibitor, pifithrin-α, significantly reduced cytotoxicity, genotoxicity, PARP-1 cleavage, caspase 3 activation, and p53 phosphorylation induced by 1-NP. We propose that cytotoxicity and genotoxicity induced by 1-NP by PARP-1 cleavage via caspase-3 and -9 activation through cytochrome c release from mitochondria and its upstream p53-dependent pathway in macrophages.

Thiazoles can also be used as protected formyl groups, which can be released in later stages of complex natural product synthesis. The pyridine-type nitrogen in the thiazole ring deactivates the ring for electrophilic substitution reactions, which is further reduced in acid due to protonation of the thiazole ring.Application of 63208-82-2

P53/NRF2 mediates SIRT1’s protective effect on diabetic nephropathy was written by Ma, Fuzhe;Wu, Junduo;Jiang, Ziping;Huang, Wenlin;Jia, Ye;Sun, Weixia;Wu, Hao. And the article was included in Biochimica et Biophysica Acta, Molecular Cell Research in 2019.Safety of 2-(2-Imino-4,5,6,7-tetrahydrobenzothiazol-3-yl)-1-p-tolylethanone Hydrobromide The following contents are mentioned in the article:

Diabetic nephropathy (DN) is the leading cause of end stage renal disease, posing a severe threat to public health. Previous studies reported the protective role of sirtuin 1 (SIRT1) in DN, encouraging the investigation of more potent and specific SIRT1 activators. SRT2104 is a novel, first-in-class, highly selective small-mol. activator of SIRT1, with its effect and mechanism unknown on DN. To this end, streptozotocin-induced C57BL/6 wild-type (WT) diabetic mice were treated with SRT2104, for 24 wk. To determine whether SRT2104 acted through inhibition of P53 – a substrate of SIRT1, the P53 activator nutlin3a was administered to the WT diabetic mice in the presence of SRT2104. In order to test whether nuclear factor erythroid 2-related factor 2 (NRF2) – the master of cellular antioxidants – mediated SIRT1 and P53’s actions, WT and Nrf2 gene knockout (KO) diabetic mice were treated with SRT2104 or the P53 inhibitor pifithrin-α (PFT-α). In the WT mice, SRT2104 enhanced renal SIRT1 expression and activity, deacetylated P53, and activated NRF2 antioxidant signaling, providing remarkable protection against the DM-induced renal oxidative stress, inflammation, fibrosis, glomerular remodeling and albuminuria. These effects were completely abolished in the presence of nutlin3a. Deletion of the Nrf2 gene completely abrogated the efficacies of SRT2104 and PFT-α in elevating antioxidants and ameliorating DN, despite their abilities to activate SIRT1 and inhibit P53 in the Nrf2 KO mice. The present study reports the beneficial effects of SRT2104 on DN, uncovering a SIRT1/P53/NRF2 pathway that modulates the pathogenesis of DN.

Nanoemulgel for Improved Topical Delivery of Desonide: Formulation Design and Characterization was written by Ma, Qiuyan;Zhang, Jing;Lu, Bohong;Lin, Huaqing;Sarkar, Rajib;Wu, Tao;Li, Xuee. And the article was included in AAPS PharmSciTech in 2021.Category: thiazole The following contents are mentioned in the article:

This research aimed to develop a novel drug delivery system to improve treatment of skin disorders. The system is comprised of a Carbopol 980-based nanoemulgel (NE-gel) containing a desonide (DES; 0.05%, weight/weight) nanoemulsion (NE), which has a small particle size, high encapsulation efficiency, good thermodn. stability, good permeation ability, and high skin retention. DES-loaded NE (DES-NE) was prepared by high-pressure homogenization. The developed formulation was characterized by differential scanning calorimetry (DSC), X-ray diffraction, drug release, skin permeation, and drug retention. DES in vitro release and skin permeation studies with different formulations of artificial membrane and rat abdominal skin were performed with the Franz diffusion cell system. Confocal laser scanning microscopy (CLSM) was used to detect the localization and permeation pathways of drugs in the skin. Compared with com. available gel (CA-gel) and NE, the NE-gel release process conformed to the Higuchi release model (R2 = 0.9813). NE-gel prolonged the drug release time and allowed for reduced administration dose and frequency. The unit cumulative permeation of NE and NE-gel through the skin for 12 h was 63.13 ± 2.78 and 42.53 ± 2.06μg/cm², resp., values significantly higher (p < 0.01) than that of the CA-gel (30.65 ± 1.25μg/cm²) and CA-cream (15.21 ± 0.97μg/cm²). The DES-NE and DES NE-gel skin drug retention was significantly higher than com. available formulations (p < 0.01). Hence, the prepared NE-gel is a potential vehicle for improved topical DES delivery for better treatment of skin disorders. This study involved multiple reactions and reactants, such as 3-(Benzo[d]thiazol-2-yl)-7-(diethylamino)-2H-chromen-2-one (cas: 38215-36-0Category: thiazole).

3-(Benzo[d]thiazol-2-yl)-7-(diethylamino)-2H-chromen-2-one (cas: 38215-36-0) belongs to thiazole derivatives. The higher aromaticity of thiazole is due to delocalization of a lone pair of sulfur electrons across the ring, which is evidenced by chemical shifts of ring hydrogen at δ 7.27 and 8.77 ppm (C2 and C4), indicating diamagnetic ring current.Various laboratory methods exist for the organic synthesis of thiazoles. For example, 2,4-dimethylthiazole is synthesized from thioacetamide and chloroacetone.Category: thiazole

Subarachnoid hemorrhage (SAH) is a fatal disease. Within 72 h of SAH, the intracranial blood-brain barrier (BBB) is destroyed, and the nerve cells have responses such as autophagy, apoptosis, and oxidative stress. Antioxidation is an essential treatment of SAH. Astaxanthin (ATX) induces cells’ antioxidant behaviors by regulating related signal pathways to reduce the damage of brain oxidative stress, inflammation, and apoptosis. Because of its easy degradability and low bioavailability, ATX is mainly encapsulated with stimulus-responsive nanocarriers to improve its stability, making it rapidly release in the brain and efficiently enter the lesion tissue. In this study, the ultrasonic cavitation agent perfluorocarbon (PFH), ATX, and fluorescent dye IR780 were loaded with polydopamine (PDA) to prepare a US triggered release nanoparticles (AUT NPs). The coreshell structure of AUT NPs formed a phys. barrier to improve the bioavailability of ATX. AUT NPs have high ATX loading capacity and US responsiveness. The exptl. results show that the AUT NPs have high stability in the physiol. environment. Both US and pH stimuli can trigger the release. Under US, PFH breaks through the rigid shell. The structure of AUT NPs is destroyed in situ, releasing the loaded drugs into neuronal cells to realize the antioxidant and antiapoptotic effects. The in vivo experiment results show that the AUT NPs have good biosafety. They release the drugs in the brain under stimuli. The in vivo treatment results also show that AUT NPs have an excellent therapeutic effect. This approach presents an exptl. basis for the establishment of Innovative SAH treatments.

Pifithrin-α ameliorates glycerol induced rhabdomyolysis and acute kidney injury by reducing p53 activation was written by Chen, Yuqiang;Zhang, Lisha;Wen, Jiejun;Qin, Xue;Wang, Niansong. And the article was included in Renal Failure in 2022.Synthetic Route of C16H19BrN2OS The following contents are mentioned in the article:

ObjectivesRhabdomyolysis is a series of symptoms caused by the dissolution of striped muscle, and acute kidney injury (AKI) is a potential complication of severe rhabdomyolysis. The underlying causes of AKI are remarkably complex and diverse. Here, we aim to investigate whether pifithrin-α protected against rhabdomyolysis-induced AKI and to determine the involved mechanisms. MethodsIntramuscular injection in the right thigh caudal muscle of C57BL/6J mice with 7.5 mL/kg saline (Group A) or of the same volume 50% glycerol was used to induce rhabdomyolysis and subsequent AKI (Group B). Pifithrin-α was injected i.p. 4 h before (Group C) or 4 h after (Group D) the glycerol injection. Serum creatine kinase, blood urea nitrogen, and creatinine were determined, and the renal cortex was histol. analyzed. Renal expression levels of interested mRNAs and proteins were determined and compared, too. ResultsIntramuscular injection of glycerol induced rhabdomyolysis and subsequent AKI in mice (Groups B-D). Renal function reduction and histol. injury of renal tubular epithelial cells were associated with increased p53 activation, oxidative stress, and inflammation. Notably, compared with pifithrin-α rescue therapy (Group D), pretreatment of pifithrin-α (Group C) protected the mice from severe injury more effectively. ConclusionsOur present study suggests that p53 may be a therapeutic target of AKI caused by glycerol, and the inhibition of p53 can block glycerol-mediated AKI by using pharmacol. agents instead of genetic inhibitory approaches, which further supports that p53 played a pivotal role in renal tubular injury when challenged with glycerol.
