Sp-cAMPS sodium salt 作为 cAMP 类似物,是一种依赖 cAMP 的PKA I 和PKA II 的有效激活剂。Sp-cAMPS sodium salt 还是一种有效的竞争性磷酸二酯酶 (PDE3A) 抑制剂,Ki 为 47.6 μM。Sp-cAMPS sodium salt 结合PDE10 GAF 结构域,EC50为 40 μM 。
Carbazomycin D is a bacterial metabolite that has been found inStreptomycesand has diverse biological activities.1,2It is active against the fungiT. asteroidesandT. mentagrophytes(MIC = 100 μg ml for both) and the bacteriumM. tuberculosis(IC50= 25 μg ml). Carbazomycin D is cytotoxic to MCF-7, KB, NCI H187, and Vero cells (IC50s = 21.3, 33.2, 12.9, and 34.3 μg ml, respectively).2 1.Naid, T., Kitahara, T., Kaneda, M., et al.Carbazomycins C, D, E and F, minor components of the carbazomycin complexJ.
