Indole-substituted oxazolidinones, oxazolones, pyrrolidinone, imidazolidinone and imidazolones were synthesized. Their inhibitory potencies towards protein kinase C and protein kinase A were determined and their in vitro activities against Streptomyces chartreusis, Streptomyces griseus, Bacillus cereus, Candida albicans and Escherichia coli were examined. The inhibition of Streptomyces sporulation
合成了

咪唑烷酮和
咪唑啉酮。确定了它们对蛋白激酶C和蛋白激酶A的抑制能力,并检测了它们对黄绿色链霉菌,灰链霉菌,蜡状芽孢杆菌,白色念珠菌和大肠杆菌的体外活性。对于其中一些观察到的链霉菌孢子形成的抑制作用与体外蛋白激酶C的抑制作用没有联系。全部被证明对白色念珠菌无活性,但其中三个对大肠杆菌表现出明显的活性。这种作用扩展到其他革兰氏阴性细菌。
