Abstract: We designed and engineered novel intravaginal ring (IVR) medical devices via fused deposition modeling (FDM) three-dimensional (3D) printing for controlled delivery of hydroxychloroquine, IgG, gp120 fragment (encompassing the CD4 binding site), and coumarin 6 PLGA-PEG nanoparticles (C6NP). The hydrophilic polyurethanes were utilized to 3D-print reservoir-type IVRs containing a tunable release controlling membrane (RCM) with varying thickness and adaptable micro porous structures (by altering the printing patterns and interior fill densities) for controlled sustained drug delivery over 14 days. FDM 3D printing of IVRs were optimized and implemented using a lab-developed Cartesian 3D printer. The structures were investigated by SEM (SEM) imaging and in vitro release was performed using 5 mL of daily-replenished vaginal fluid simulant (pH 4.2). The release kinetics of the IVR segments were tunable with various RCM (outer diameter to inner diameter ratio ranging from 1.12 to 2.61) produced from FDM 3D printing by controlling the printing perimeter to provide daily zero-order release of HCQ ranging from 23.54 ± 3.54 to 261.09 ± 32.49μg/mL/day. IgG, gp120 fragment, and C6NP release rates demonstrated pattern and in-fill d.-dependent characteristics. The current study demonstrated the utility of FDM 3D printing to rapidly fabricate complex micro-structures for tunable and sustained delivery of a variety of compounds including HCQ, IgG, gp120 fragment, and C6NP from IVRs in a controlled manner. This study involved multiple reactions and reactants, such as 3-(Benzo[d]thiazol-2-yl)-7-(diethylamino)-2H-chromen-2-one (cas: 38215-36-0Related Products of 38215-36-0).

Urea transporter B downregulates polyamines levels in melanoma B16 cells via p53 activation was written by Li, Jiajing;Sun, Yuxin;Yan, Ruyu;Wu, Xiaolin;Zou, Hualong;Meng, Yan. And the article was included in Biochimica et Biophysica Acta, Molecular Cell Research in 2022.HPLC of Formula: 63208-82-2 The following contents are mentioned in the article:

Urea transporter B (UT-B, encoded by the SLC14A1 gene) is a membrane channel protein involved in urea transmembrane transport. Compared with normal tissues, UT-B expression is significantly decreased in most tumors, especially melanoma. However, the UT-B role in tumorigenesis and development is still unclear. Herein, we investigated the effects of UT-B overexpression on polyamine metabolism and the urea cycle in murine melanoma B16 cells, to explore the roles of mitochondrial dysfunction and p53 activation in cell growth and polyamines metabolism UT-B overexpression in B16 cells decreased cell growth, increased apoptosis, and significantly altered metabolic pathways related to the urea cycle, which were characterized by reduced production of urea and polyamines and increased production of nitric oxide. Subsequently, we observed that activation of the p53 pathway may be the main cause of the above phenomena. The p53 inhibitor pifithrin-α partially restored the production of polyamines, but the mitochondrial morphol. and function were still impaired. Further treatment of UT-B-overexpressing B16 cells with reactive oxygen species scavenging agent N-acetyl-L-cysteine and coenzyme Q10 restored cell viability and mitochondrial function and increased polyamine production In conclusion, UT-B overexpression caused mitochondrial dysfunction and increased oxidative stress in B16 cells, and then activated p53 expression, which may be one of the mechanisms leading to the decrease in intracellular polyamines. This study involved multiple reactions and reactants, such as 2-(2-Imino-4,5,6,7-tetrahydrobenzothiazol-3-yl)-1-p-tolylethanone Hydrobromide (cas: 63208-82-2HPLC of Formula: 63208-82-2).

Dermal fibroblasts are responsible from the production of extracellular matrix and take role in the closure of skin wounds. Dermal fibroblasts are major cells of origin in the generation of induced pluripotent stem cells (IPSCs) and are historically being used as feeder layer and biofiller in the restorative surgeries. ex vivo expansion of the dermal fibroblasts provides a suitable model to study skin biol. and to engineer bioartifical skins. Thus, development of efficient fibroblast expansion technologies gets outmost importance day by day. We sought to identify small mols. that induce ex vivo fibroblast expansion and understand their mechanisms. We analyzed the effect of 35 small mols., which are expected to target mol. pathways involving cellular quiescence. We have found that small mols., especially AS1949490 and SKF96365, increase human dermal fibroblast expansion of at least three different fibroblasts. Cell cycle anal. confirms that these small mols. allow cell cycle progression, as evident by increased percentage of cells in S-G2-M phase of cell cycle. They led to a lower profile of apoptotic or necrotic fibroblasts. Intriguingly, we have found that identified small mols. could also endogenously induce the expression of IPSC generation, collagen synthesis, and aging-related genes. Identified small mols. may contribute to the induction of collagen synthesis in the biofiller products, the development of fibroblast products with better aging profile, and the improvement of IPSC generation.

The abnormal proliferation and hypertrophy of adipocytes mediate the expansion of adipose tissue and then cause obesity-related diseases. Theor., an approach for preventing and curing obesity is to inhibit cell proliferation during the mitotic clonal expansion (MCE) progression of adipocyte differentiation. Polycyclic polyprenylated acylphloroglucinols (PPAPs) are mainly found from Hypericum and Garcinia genus, which have been reported to have various biol. activities such as anti-depressant, anti-oxidant, and anti-tumor. Previously, our group has reported that adamantane-type PPAPs exhibited blunting activity in adipogenesis. In this study, another six adamantane PPAPs were screened to investigate their anti-adipogenesis activities and then discussed the structure-activity relationship. Particularly, sampsonione F, one of the PPAPs dramatically suppressed adipogenesis dose-dependently in vitro, along with decreased expressions of C/EBPβ, C/EBPα, PPARγ, FABP4, and FAS. Moreover, sampsonione F upregulated the expression of p27 by activating p53 pathway and then downregulated the expressions of key regulators during G1/S phase arrest. Our data support that sampsonione F suppressed adipogenesis by activating p53 pathway, regulating cyclins, and resulting in G1/S phase arrest during the MCE progression of adipogenesis. This work provides a new adamantane-type PPAPs in the regulation of adipogenesis and extends our knowledges on the mechanism of the type PPAPs in regulation of adipogenesis.

2-(2-Imino-4,5,6,7-tetrahydrobenzothiazol-3-yl)-1-p-tolylethanone Hydrobromide (cas: 63208-82-2) 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. Electrophilic attack at nitrogen depends on the presence of electron density at nitrogen as well as the position and nature of substituent linked to the thiazole ring.Computed Properties of C16H19BrN2OS

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.

Thiazoles can also be used as protected formyl groups, which can be released in later stages of complex natural product synthesis. Thiazole sulfonation occurs only under forcing conditions: the action of oleum at 250 °C for 3 hours in the presence of mercury(II) sulfate leads to 65% formation of 5-thiazole sulfonic acid.Safety of 2-(2-Imino-4,5,6,7-tetrahydrobenzothiazol-3-yl)-1-p-tolylethanone Hydrobromide

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.

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.

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.

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.

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.

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.
