A new series of 7-alkoxy[1,2,4]triazolo[3,4-b]benzothiazol-3(2H)-ones were synthesized and evaluated for their anticonvulsant activities. Among these compounds, 7-propoxy[1,2,4]triazolo[3,4-b]benzothiazol-3(2H)-one and 7-butoxy[1,2,4]triazolo[3,4-b]benzothiazol-3(2H)-one (I) showed the highest activity against maximal electroshock (MES)-induced tonic extension [(ED)₅₀ = 11.4 and 13.6 mg/kg, resp.]. It is worth mentioning that compound I showed especially low neurotoxicity, which led to a high protective index (PI >51). The orally anticonvulsant activity data of compound I further confirmed its efficacy, in an MES test, and its high safety with a PI value of 50.2. In addition, the potency of compound I against seizures induced by pentylenetetrazole, 3-mercaptopropionic acid, and bicuculline in the chem.-induced seizure tests suggested that compound I may exert its anticonvulsant activity through affecting the GABAergic system. This study involved multiple reactions and reactants, such as 6-Butoxybenzo[d]thiazol-2-amine (cas: 14372-65-7Computed Properties of C11H14N2OS).

Anti-fibrotic effects of p53 activation induced by RNA polymerase I inhibitor in primary cardiac fibroblasts was written by Pang, Shu;Chen, Ye;Dai, Chaochao;Liu, Tengfei;Zhang, Wenjing;Wang, Jianli;Cui, Xiaopei;Guo, Xiaosun;Jiang, Fan. And the article was included in European Journal of Pharmacology in 2021.Recommanded Product: 2-(2-Imino-4,5,6,7-tetrahydrobenzothiazol-3-yl)-1-p-tolylethanone Hydrobromide The following contents are mentioned in the article:

Several lines of studies have indicated that the p53 pathway may have important anti-fibrotic functions. Previously we found that the novel selective RNA polymerase I inhibitor CX-5461 induced a robust response of p53 phosphorylation and activation in vascular smooth muscle cells. In the present study, we characterized the anti-fibrotic effects of CX-5461 in primary cardiac fibroblasts. We showed that CX-5461 suppressed spontaneous and mitogen-stimulated activation, proliferation, and myofibroblast differentiation, at a concentration (1μM) with no cytotoxicity. The inhibitory effects of CX-5461 were primarily mediated by activation of the p53 pathway rather than limiting the rate of ribosome biogenesis. It was also shown that CX-5461 triggered a non-canonical DNA damage response in cardiac fibroblasts, which acted as the upstream signal leading to p53 activation. Taking these together, we suggest that p53 activation by pharmacol. inhibition of Pol I may represent a viable approach to repress the development of cardiac fibrosis. This study involved multiple reactions and reactants, such as 2-(2-Imino-4,5,6,7-tetrahydrobenzothiazol-3-yl)-1-p-tolylethanone Hydrobromide (cas: 63208-82-2Recommanded Product: 2-(2-Imino-4,5,6,7-tetrahydrobenzothiazol-3-yl)-1-p-tolylethanone Hydrobromide).

7-Ethyl-10-hydroxycamptothecin (SN-38)-loaded polyethylene glycol-GPLGVRG-poly β-benzyl-L-aspartic acid (PEG-GPLGVRG-PBLA) self-assemblies were successfully prepared using a classical nanopptn. method to give an enzyme-responsive nano-drug delivery system. The PEG-GPLGVRG-PBLA/SN-38 self-assemblies were characterized by transmission electron microscopy, dynamic light scattering, and high-performance liquid chromatog. The encapsulation efficiency was 91.7 ± 1.21% and the drug loading was 16.6 ± 0.93%. The 12 h in vitro release of SN-38 from PEG-GPLGVRG-PBLA/SN-38 treated with MMP-2 was 73.2 ± 2.05%, which was significantly higher than that for the group without MMP-2, demonstrating the enzyme-responsiveness of the nano-drug delivery system. In addition, the cellular uptake and tumor accumulation of PEG-GPLGVRG-PBLA were better than those of PEG-PBLA, and the blank PEG-GPLGVRG-PBLA showed high biocompatibility. These findings indicate that the enzyme-responsive nano SN-38 delivery system could provide new opportunities in tumor therapy.

To improve the loading and delivery for hydrophobic drugs and optimize the release efficiency in tumor microenvironment, a novel core-shell magnetic micro-organogel carrier was successfully prepared by a sono-catalysis process in the study. As-synthesized magnetic micro-organogel had an appropriate dispersibility in water owing to the hydrophilicity of protein shell and could be kept steadily with a well-defined spherical morphol. owing to the three-dimensional gel structure of oil core, and it promised an accessible targeted drug delivery owing to its good magnetism-mediated motion ability. Moreover, the magnetic micro-organogel showed a high loading efficiency up to 94.22% for coumarin 6 which was dissolved into the micro-organogel as a model hydrophobic drug. More importantly, the release kinetics revealed that the magnetic micro-organogel had a thermo-sensitive and glutathione (GSH)-sensitive ability to control the drug release, and proved that its release mechanisms referred to the combination of erosion, diffusion and degradation This study involved multiple reactions and reactants, such as 3-(Benzo[d]thiazol-2-yl)-7-(diethylamino)-2H-chromen-2-one (cas: 38215-36-0Electric Literature of C20H18N2O2S).

Inducing cell death while simultaneously enhancing antitumor immune responses is a promising therapeutic approach for multiple cancers. Celastrol (Cel) and 7-ethyl-10-hydroxycamptothecin (SN38) have contrasting physicochem. properties, but strong synergy in immunogenic cell death induction and anticancer activity. Herein, a hypoxia-sensitive nanosystem (CS@TAP) was designed to demonstrate effective immunotherapy for colorectal cancer by systemic delivery of an immunostimulatory chemotherapeutic combination. Furthermore, the combination of CS@TAP with anti-PD-L1 mAb (αPD-L1) exhibited a significant therapeutic benefit of delaying tumor growth and increased local doses of immunogenic signaling and T-cell infiltration, ultimately extending survival. We conclude that CS@TAP is an effective inducer of immunogenic cell death (ICD) in cancer immunotherapy. Therefore, this study provides an encouraging strategy to synergistically induce immunogenic cell death to enhance tumor cytotoxic T lymphocytes (CTLs) infiltration for anticancer immunotherapy.

And the article was included in Journal of Biomedical Nanotechnology in 2021.Application of 38215-36-0 The following contents are mentioned in the article:

Radioresistance limits the effectiveness of radiotherapy for hepatocellular carcinoma. Raf and PI3K signaling cascades promote the formation of radioresistance in hepatocellular carcinoma (HCC). Lupeol has anticancer activity despite its poor solubility in water and is toxic effect on normal tissue. In this study, nanoparticles (lupeol-NPs) were constructed using PEG-PLGA diblock copolymer vector, and results revealed that Lupeol-NPs reversed the radioresistance of hepatocellular carcinoma by inhibiting cellular proliferation and cell-cycle progression and promoting cellular apoptosis through blocking Raf/MAPK and PI3K/Akt signal transduction in radioresistant Huh-7R cells. In vivo, Lupeol-NPs combined with radiotherapy inhibited the growth of radioresistant hepatocellular carcinoma in a xenogenic nude mouse model. Ki-67 proliferation index decreased significantly (p < 0.05). We conclude that Lupeol-NPs can increase the sensitivity of radioresistant hepatocellular carcinoma to radiotherapy through inhibiting the Raf and PI3K signal cascades.

Background/Aim: Despite advances in treatment modalities, the visual prognosis of retinoblastoma still remains unsatisfactory, underscoring the need to develop novel therapeutic approaches. Materials and Methods: The effect on the growth of six human retinoblastoma cell lines and a normal human fibroblast cell line of CEP1347, a small-mol. kinase inhibitor originally developed for the treatment of Parkinson’s disease and therefore with a known safety profile in humans, was examined The role of the P53 pathway in CEP1347-induced growth inhibition was also investigated. Results: CEP1347 selectively inhibited the growth of retinoblastoma cell lines expressing murine double minute 4 (MDM4), a P53 inhibitor. Furthermore, CEP1347 reduced the expression of MDM4 and activated the P53 pathway in MDM4-expressing retinoblastoma cells, which was required for the inhibition of their growth by CEP1347. Conclusion: We propose CEP1347 as a promising candidate for the treatment of retinoblastomas, where functional inactivation of P53 as a result of MDM4 activation is reportedly common.

GDF15 mediates the metabolic effects of PPARβ/δ by activating AMPK was written by Aguilar-Recarte, David;Barroso, Emma;Guma, Anna;Pizarro-Delgado, Javier;Pena, Lucia;Ruart, Maria;Palomer, Xavier;Wahli, Walter;Vazquez-Carrera, Manuel. And the article was included in Cell Reports in 2021.Computed Properties of C16H19BrN2OS The following contents are mentioned in the article:

Peroxisome proliferator-activated receptor β/δ (PPARβ/δ) activates AMP-activated protein kinase (AMPK) and plays a crucial role in glucose and lipid metabolism Here, we examine whether PPARβ/δ activation effects depend on growth differentiation factor 15 (GDF15), a stress response cytokine that regulates energy metabolism Pharmacol. PPARβ/δ activation increases GDF15 levels and ameliorates glucose intolerance, fatty acid oxidation, endoplasmic reticulum stress, and inflammation, and activates AMPK in HFD-fed mice, whereas these effects are abrogated by the injection of a GDF15 neutralizing antibody and in Gdf15-/- mice. The AMPK-p53 pathway is involved in the PPARβ/δ-mediated increase in GDF15, which in turn activates again AMPK. Consistently, Gdf15-/- mice show reduced AMPK activation in skeletal muscle, whereas GDF15 administration results in AMPK activation in this organ. Collectively, these data reveal a mechanism by which PPARβ/δ activation increases GDF15 levels via AMPK and p53, which in turn mediates the metabolic effects of PPARβ/δ by sustaining AMPK activation.
