A new protocol for the direct synthesis of 2-aminothiazole has been developed from oxime acetate and readily available sodium thiocyanate using a copper catalyst. The present transformation has good functional group tolerance. Various thiazoles were smoothly synthesized in good to excellent yields. The applicability of the present method has been extended to the formal synthesis of the non-steroidal

Design and development of novel fasudil derivatives as potent antibreast cancer agent that improves intestinal flora and intestinal barrier function in rats
This study was conducted to develop novel fasudil derivatives after incorporation of substituted thiazoles as potent anti-breast cancer (BC) agents. The compounds were developed using a facile syntheticroute in excellent yields. The entire set of developed compounds was tested for inhibitory activity against rho-associated coiled-coil kinase (ROCK; ROCK1 and ROCK2) kinase, where they exhibit potent
本研究的目的是在掺入取代噻唑后开发新型法舒地尔衍生物作为有效的抗乳腺癌 (BC) 药物。这些化合物采用简便的合成路线开发而成,收率优异。测试了整套开发的化合物对 rho 相关卷曲螺旋激酶(ROCK;ROCK1 和 ROCK2)的抑制活性,与 ROCK2 相比,它们表现出对 ROCK1 的有效和选择性抑制。最有效的 ROCK2 抑制剂,化合物6h显着抑制 BC 细胞 (MCF-7) 的活力。它还会抑制 MCF-7 细胞的迁移和侵袭。此外,在雌性 Sprague Dawley 大鼠中研究了化合物6h在 7,12二甲基苯并蒽 (DMBA) 诱导的 BC 中的抗 BC 活性。结果表明,它可以显着改善动物的体重,并减少大鼠肝脏和乳腺组织的氧化应激。它通过恢复二胺氧化酶、 d-乳酸和内毒素的水平来改善大鼠的肠道屏障功能。在蛋白质印迹分析中,与DMBA组相比,大鼠结肠组织中的(ZO-1)、occludi
