酰基氨基苯并噻唑命中被确定为克氏锥虫复制的潜在抑制剂,锥虫是负责恰加斯病的寄生虫。我们选择化合物1进行铅优化,旨在同时提高其抗克鲁氏锥虫活性(IC 50 = 0.63μM)和其人类代谢稳定性(人类清除率= 9.57 mL / min / g)。总共合成了39种1的类似物,并在体外进行了测试。我们建立了多参数结构与活性的关系,从而可以优化抗寄生虫活性,理化参数和ADME特性。我们将化合物50鉴定为具有改进的体外抗T. cruzi活性的高级铅(IC50 = 0.079μM)和增强的代谢稳定性(人类清除率= 0.41 mL / min / g)和口服途径。在耐受性评估后,有50种药物显示出有希望的体内功效。

We have developed a series of novel potent ortho-substituted azole derivatives active against kinases VEGFR-1 and VEGFR-2. Both specific and dual ATP-competitive inhibitors of VEGFR-2 were identified. Kinase activity and selectivity could be controlled by varying the arylamido substituents at the azole ring. The most specific molecule (17) displayed > 10-fold selectivity for VEGFR-2 over VEGFR-1. Compound

An efficient and convenient method of synthesis of 2-chloro-4,6-dimethoxy-1,3,5-triazine from cyanuric chloride in a short reaction time followed by synthesis of biological active novel substituted 4,6-dimethoxy-N-phenyl-1,3,5-triazin-2-amine (4a-x) using substituted anilines and heterocyclic amines, anhydrous K2CO3 in dry THF as solvent has been developed. Advantages of this methodology are short reaction time, excellent yield of products, easy work-up procedure. The synthesized compounds were confirmed by FT-IR, 1H NMR, mass spectral data. All the synthesized derivatives (4a-x) were screened for their antibacterial activity against Staphylococcus aureus, Bacillus subtilis, Escherichia coli, Pseudomonas aeruginosa species and antifungal activities against Candida albicans MTCC 227, Candida glabrata NCIM 3236, Candida tropicalis NCIM 3110 and Aspergillus niger NCIM 545 species.
