Carbazomycin A is a bacterial metabolite that has been found in Streptomyces and has diverse biological activities.1,2It is active againstS. aureus,T. asteroides, andT. mentagrophytes(MIC = 12.5 μg/ml for all), as well as the plant pathogenic fungusP. oryzae(MIC = 25 μg/ml). Carbazomycin A is cytotoxic to MCF-7, KB, NCI H187, and Vero cells (IC50s = 26.2, 30.1, 18.4, and 32.6 μg/ml, respectively).2 1.Sakano, K.-I., Ishimaru, K., and Nakamura, S.New antibiotics, carbazomycins A and B.

Carbazomycin B is a bacterial metabolite that has been found in Streptomyces and has diverse biological activities. It is active against a panel of seven fungi and a panel of seven bacteria, as well as P. falciparum and C. albicans. It is also active against a panel of five plant pathogenic fungi. Carbazomycin B is cytotoxic to MCF-7, KB, NCI H187, and Vero cells. It also inhibits 5-lipoxygenase (5-LO) activity in RBL-1 cell extracts (IC50 = 1.5 µM).

Cyclothiazomycin 选择性抑制肾素活性，不影响胃蛋白酶、天冬氨酸、丝氨酸、硫醇蛋白酶以及金属蛋白酶的活性。此外，Cyclothiazomycin 表现出相对较弱的抗真菌活性。

Pyrazomycin II (Pyrazomycin B) 是一种抗生素，并且作为嘧啶核苷代谢的竞争性抑制剂。

Azotomycin is an antagonist of L-glutamine and may be used as an immunosuppressant.

Kahweol linoleate is a semi-syntetic derivative of kahweol, a natural product found in coffee beans. It exhibits a wide variety of biological activities, including inhibiting RANKL-induced osteoclast generation, inducing cell cycle arrest and apoptosis in oral squamous cell carcinoma cells, preventing aflatoxin B1 induced DNA adduct formation, and suppressing H2O2-induced DNA damage and oxidative stress.
