Daucosterol (DS) is a plant phytosterol which is shown to induce oxidative stress mediated apoptosis in various cancer cell lines. However, the mol. mechanism underlying its cellular action has not been documented against Non- Small Cell Lung Cancer (NSCLC). Therefore, we attempted to decipher the mechanisms responsible for DS-induced anti-proliferation on human NSCLC cells. The present study showed, DS strongly inhibits the growth of A549 cells after 72 h time point with an IC₅₀ value of ~20.9μM. Further DS elicits increased reactive oxygen species level and promote intrinsic apoptotic cell death on A549 cells as evidenced by increased expression of caspase-3, caspase-9, Bax, PARP inactivation, cytochrome-c release, and diminished expression of bcl-2 protein. DS failed to display its apoptotic actions upon pretreatment with the reactive oxygen species inhibitor NAC (N-acetyl cysteine). Indeed, apoptotic signal which was enhanced through p53/p21 activation and knockdown of p53 expression also moderately affected the DS induced apoptosis. In addition, DS preferentially inhibited the cell growth of p53 wild-type NSCLC cell lines than the mutant p53 models. Further, we show that inhibition of Thioredoxin (TrxR) redox system is principally associated with DS induced oxidative stress mediated apoptotic cell death on A549 cells. Moreover, we also demonstrated that DS stably interacted with serine residues in TrxR active sites. The obtained results confirmed that the anti-proliferative mechanism and increased reactive oxygen species level of DS was associated with down-regulation of TrxR1 pathway which triggers the p53 mediated intrinsic apoptotic mode of cell death in NSCLC cells. 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).

2-(2-Imino-4,5,6,7-tetrahydrobenzothiazol-3-yl)-1-p-tolylethanone Hydrobromide (cas: 63208-82-2) belongs to thiazole derivatives. Thiazoles are a class of five-membered rings containing nitrogen and sulfur with excellent antitumor, antiviral and antibiotic activities. The nitrogen in thiazole is sp2 hybridized and the lone pair of electrons localized on the nitrogen is less reactive due to increased aromatic character and decreased basicity. It is protonated and alkylated/acylated at nitrogen forming hydrochloride and quaternary thiazolium salt.Computed Properties of C16H19BrN2OS

Atopic dermatitis is characterized by leukocyte migration into the skin dermis and typically driven by excessive chemokine production at the site of inflammation. Conventional topical formulations such as gels, creams, and ointments are insufficient for this treatment because of low penetration of drug mols. into the targeted skin tissues. Herein, using a simple, green, sustainable strategy, we have developed novel primary zein nanoparticles embedded in curcumin (Cur) and coated with silk sericin (ZHSCs) for the topical delivery of Cur to penetrate into the dermis and exercise anti-dermatitis effects on the lesion with minimal side-effects. Transdermal delivery experiments and porcine skin fluorescence imaging indicated that ZHSCs facilitate the penetration of Cur across the epidermis layer of skin to reach deep-seated sites. Notably, ZHSCs = 1:0.25 (zein-to-silk sericin mass ratios of 1:0.25) markedly elevated the skin permeability and cumulative turnover of Cur transferred, which were provided a greater than a 3.8-fold increase relative to free Cur. The special nanoparticles of ZHS = 1:0.25 possessed the deepest localization depth and experience a transition of the particle structure and core-shell separation after penetrating into the dermis of skin. In a cell model of dermatitis induced by tumor necrosis factor α/interferon γ co-stimulation, compared with free Cur, Cur-loaded ZHS nanoparticles down-regulated the generation of inflammatory cytokines and chemokines in keratinocytes through suppression of the nuclear translocation of NF-κBp65 and hence exerted an anti-dermatitis effect. This strategy may provide new avenues and direction for the demanding issues of valid topical delivery systems.

The neurotoxicity of local anesthetics (LAs) has attracted more and more attention, However, they lack preventive and therapeutic measures. Many studies have shown that apoptosis plays an important role in the process of LA-induced neurotoxicity. As an important signaling mol. to activate apoptosis, p53 has been proved to be involved in the neurotoxicity induced by LAs, but the mechanism is unclear. In this study, we explored the effect of pifithrin-α (PFT-α), a p53 inhibitor, on apoptosis by ropivacaine (Rop) in vivo and in vitro. Cell viability and apoptosis detected by CCK-8 and a JC-1 apoptosis detection kit, the changes of spinal cord structure observed after hematoxylin and eosin staining, apoptosis of the spinal cord measured by terminal deoxynucleotidyl transferase dUTP nick end labeling staining, behavioral assessment of the nerve Injury evaluated by the detection of sciatic nerve conduction velocity (SNCV) andmech. withdrawal threshold (MWT), the expression of p53 and many apoptosis-related genes included Bax, Bcl-2, and caspase-3 detected by quant. real-time polymerase chain reaction, Western blot anal., immunofluorescence, and immunohistochem. Results showed that PC12 cell viability decreased because of Rop, but the pretreatment of PFT-α could protect it. And PFT-α reduced the injuries in the spinal cord by Rop included vacuoles or edema. The results of immunofluorescence and immunohistochem. testing showed that PFT-α inhibited the p53 protein upregulated by Rop. Apoptosis rate and many proapoptotic genes include p53, Bax, caspase-3 mRNA, and proteins were increased by Rop, but PFT-α could decrease it. In conclusion, PFT-α inhibited cell apoptosis and spinal cord injuries induced by Rop.

The present study was designed to develop pH-sensitive lipid polymer hybrid nanoparticles (pHS-LPHNPs) for specific cytosolic-delivery of docetaxel (DTX). The pHS-LPHNPs-DTX formulation was prepared by self-assembled nano-precipitation technique and characterized for zeta potential, particle size, entrapment efficiency, polydispersity index (PDI), and in vitro drug release. In vitro cytotoxicity of pHS-LPHNPs-DTX was assessed on breast cancer cells (MDA-MB-231 and MCF-7) and compared with DTX-loaded conventional LPHNPs and bare DTX. In vitro cellular uptake in MDA-MB-231 cell lines showed better uptake of pHS-LPHNPs. Further, a significant reduction in the IC50 of pHS-LPHNPs-DTX against both breast cancer cells was observed Flow cytometry results showed greater apoptosis in case of pHS-LPHNPs-DTX treated MDA-MB-231 cells. Breast cancer was exptl. induced in BALB/c female mice, and the in vivo efficacy of the developed pHS-LPHNPs formulation was assessed with respect to the pharmacokinetics, biodistribution in the vital organs (liver, kidney, heart, lungs, and spleen), percentage tumor burden, and survival of breast cancer-bearing animals. In vivo studies showed improved pharmacokinetic and target-specificity with min. DTX circulation in the deep-seated organs in the case of pHS-LPHNPs-DTX compared to the LPHNPs-DTX and free DTX. Mice treated with pHS-LPHNPs-DTX exhibited a significantly lesser tumor burden than other treatment groups. Also, reduced distribution of DTX in the serum was evident for pHS-LPHNPs-DTX treated mice compared to the LPHNPs-DTX and free DTX. In essence, pHS-LPHNPs mediated delivery of DTX presents a viable platform for developing therapeutic-interventions against breast-cancer.

Immunotherapy has emerged as one of the most promising treatments for cancer in recent years. However, it works only for a small proportion of patients, which can in part be attributed to the immunosuppressive tumor microenvironment (TME). Tumor associated macrophages (TAMs) are the critical components of tumors and play an important role in the development of the immunosuppressive TME. The transition of TAMs from the pro-tumor (M2) phenotype to anti-tumor (M1) phenotype is crucial for the immunotherapy of gastric cancer. Herein, we developed a shear-thinning, injectable hydrogel co-loaded with polyphyllin II (PP2) and resiquimod (R848) (PR-Gel) for potentiating localized immunotherapy of gastric cancer through the repolarization of TAMs. In this work, we evaluate the effects of PR-Gel on TAM repolarization and explored its therapeutic effect for localized immunotherapy. The hydrogels were synthesized through the Schiff base reactions between aldehyde-functionalized polyethylene glycol and the amino group of polylysine. A M2-to-M1 repolarization of TAMs and increased production of TNF-α and IL-6 were observed after treatment with PR-Gel in vitro. The anti-tumor efficacy of PR-Gel in a s.c. xenograft model of gastric cancer showed that the hydrogels possess good tumor growth suppression properties after a single injection. Furthermore, an increased iNOS/CD206 ratio in TAMs and enhanced CD8+ T cell infiltration were also observed within the TME after the treatment with PR-Gel. Hence, the biocompatible, shear-thinning, injectable hydrogels are a promising noninvasive drug-delivery platform for the regulation of the immunosuppressive TME and have great potential in localized immunotherapy against gastric cancer.

Compared with paclitaxel, sirolimus has been more used in the treatment of vascular restenosis gradually as an anti-proliferative drug, but few basic studies have elucidated its mechanism. The anti-proliferative effects of sirolimus or paclitaxel have been demonstrated by numerous studies under normoxia, but few studies have been achieved focusing hypoxia. In this study, porcine carotid artery injury model and classical cobalt chloride hypoxia cell model were established. Sirolimus nanoparticles (SRM-NPs), paclitaxel nanoparticles (PTX-NPs) and blank nanoparticles (Blank-NPs) were prepared resp. The effect of RPM-NPs on the degree of stenosis, proliferative index and the expression of PCNA after 28 days of porcine carotid artery injury model was evaluated. Compared with saline group and SRM groups, SRM-NPs group suppressed vascular stenosis, proliferative index and the expression of PCNA (P < 0.01 and P < 0.05). Endothelial cell (EC) and smooth muscle cell (SMC) were pre-treated with cobaltous chloride, followed by SRM-NPs, PTX-NPs, Blank-NPs or PBS control treating, the effects on cell proliferation, HIF-1 expression and glycolysis were detected. SRM-NPs could inhibit EC and SMC proliferation under hypoxia, while PTX-NPs couldn′t (P < 0.001). Significant differences between sirolimus and paclitaxel NPs in anti-proliferation effect under normoxia and hypoxia may due to the different inhibitory effects on HIF-1α expression and glycolysis. In conclusion, these results suggest that sirolimus can inhibit the proliferation of hypoxic cells more effectively than paclitaxel. These observations may provide a basis for understanding clin. vascular stenosis therapeutic differences between rapamycin and paclitaxel.

The clin. outcome of anti-HIV therapy is poor due to the inherent fallouts of anti-HIV therapy. It is further worsened due to the presence of viral reservoirs in immune cells like the macrophages. An ideal anti-HIV therapy must reach, deliver the drug and exert its action inside macrophages. To address this, we developed novel cationic nanostructured lipid carriers of efavirenz (cationic EFV-NLC). Th developed cationic EFV NLCs were evaluated for particle size, zeta potential, encapsulation effiency, in-vitro drug release, DSC, XRD, TEM, cytotoxicity, cellular uptake studies and anti-HIV efficy in a monocyte-derived macrophage cell line (THP-1). Cationic EFV-NLCs showed high encapsulation effiency (90.54 ± 1.7%), uniform particle size distribution (PDI 0.3-0.5 range) and high colloidal stability with pos. zeta potential (+23.86 ± 0.49 mV). DSC and XRD studies confirmed the encapsulation of EFV within NLCs. Cytotoxicity studies (MTT assay) revealed excellent cytocompatibility (CC50 13.23 ± 0.54 μg/mL). Fluorescence microscopy confirmed the effient uptake of cationic EFVNLCs, while flow cytometry revealed time and concentration dependant uptake within THP-1 cells. Cationic EFV-NLCs showed higher retention and sustained release with 2.32-fold higher percent inhibition of HIV-1 in infected macrophages as compared to EFV solution at equimolar concentrations Interestingly, they demonstrated 1.23-fold superior anti-HIV efficy over EFVloaded NLCs at equimolar concentrations Cationic NLCs were capable of inhibiting the viral replication at higher limits consistently for 6 days suggesting successful prevention of HIV-1 replication in infected macrophages and thus can prove to be an attractive tool for promising anti-HIV therapy.

Starting with Coumarin-6 dye, two novel D-π-A organic dyes C6X and C6N have been designed by attaching carboxylic acid and cyanoacrylic acid groups as anchoring groups to Coumarn-6 dye, resp., to understand their potential use in dye-sensitized solar cells (DSSCs). The electronic structure and photophys. and photovoltaic properties of the novel designed dyes were studied using d. functional theory DFT and time-dependent d. functional theory TD-DFT with the Becke3-Parameter-Lee-Yang-Parr (B3LYP) functional and the 6-31G (d, p) basis set. Optimized structure and electronic properties (HOMO energy (E_HOMO), LUMO (E_LUMO), and energy difference (E_g) between HOMO and LUMO) were calculated showing that C6N has the smallest band gap with the larger absorption region. D. of states (DOS), mol. electrostatic potential (MEP), natural bond orbital (NBO) anal., non-linear optical (NLO) properties, UV-vis spectra, as well as some crucial parameters affecting the photovoltaic performance of DSSCs, such as light-harvesting efficiency (LHE), electron injection driving force (ΔG^inject), dye regeneration driving force(ΔG^reg), and the excited state life time(τ_e), were calculated to study the effect of the anchoring group on the DSSC performance. Addnl., the adsorption of C6X and C6N dyes on the TiO₂ anatase (101) surface and the mechanism of electron injection were also investigated using a dye-(TiO₂)₉ cluster model using TD-B3LYP calculation The calculated adsorption energies of the dyes suggest a strong adsorption of dyes to a TiO₂ surface.

Coronavirus porcine epidemic diarrhea virus nucleocapsid protein interacts with p53 to induce cell cycle arrest in S-phase and promotes viral replication was written by Su, Mingjun;Shi, Da;Xing, Xiaoxu;Qi, Shanshan;Yang, Dan;Zhang, Jiyu;Han, Yuru;Zhu, Qinghe;Sun, Haibo;Wang, Xiaoran;Wu, Haoyang;Wang, Meijiao;Wei, Shan;Li, Chunqiu;Guo, Donghua;Feng, Li;Sun, Dongbo.

Subversion of the host cell cycle to facilitate viral replication is a common feature of coronavirus infections. Coronavirus nucleocapsid (N) protein can modulate the host cell cycle, but the mechanistic details remain largely unknown. Here, we investigated the effects of manipulation of porcine epidemic diarrhea virus (PEDV) N protein on the cell cycle and the influence on viral replication. Indicated that PEDV N induced Vero E6 cell cycle arrest at S-phase, which promoted viral replication (P < 0.05). S-phase arrest was dependent on the N protein nuclear localization signal S71NWHFYYLGTGPHADLRYRT90 and the interaction between N protein and p53. In the nucleus, the binding of N protein to p53 maintained consistently high-level expression of p53, which activated the p53-DREAM pathway. The key domain of the N protein interacting with p53 was revealed to be S171RGNSQNRGNNQGRGASQNRGGNN194 (NS171-N194), in which G183RG185 are core residues. NS171-N194 and G183RG185 were essential for N-induced S-phase arrest. Moreover, small mol. drugs targeting the NS171-N194 domain of the PEDV N protein were screened through mol. docking. Hyperoside could antagonize N protein-induced S-phase arrest by interfering with interaction between N protein and p53 and inhibit viral replication (P < 0.05). The above-described experiments were also validated in porcine intestinal cells, and data were in line with results in Vero E6 cells. Therefore, these results reveal the PEDV N protein interacts with p53 to activate the p53-DREAM pathway, and subsequently induces S-phase arrest to create a favorable environment for virus replication. These findings provide new insight into the PEDV-host interaction and the design of novel antiviral strategies against PEDV.
