在我们筛选缺氧诱导因子(HIF)激活剂的过程中,从放线菌菌株链霉菌属菌种的培养液中分离出A-503451 A和维伦霉素。SANK60101。从相同的培养物中,也分离出非活性同系物A-503451 B和D。A-503451 A和维伦霉素激活HIF依赖的报告基因表达,EC 50值分别为8和17 ng ml -1。它们是HIF的高效激活剂,因此可能对红细胞生成和神经细胞保护具有治疗作用。
BezE catalyzes elimination of acetic acid to form an iron nitrenoid, nitrene transfer to form an aziridine ring, and nucleophilic addition of hydroxide ion to C-10 and chloride ion to C-9 to generate the indoline and tetrahydroquinoline scaffolds, respectively. Discovery of this enzyme, which should be termed cytochrome P450 nitrene transferase, provides an important insight into the functional diversity
In the course of our screening for activators of hypoxia-inducible factor (HIF), A-503451 A and virantmycin were isolated from the cultured broth of an actinomycete strain, Streptomyces sp. SANK 60101. From the same culture, the non-active homologs A-503451 B and D were also isolated. A-503451 A and virantmycin activated HIF-dependent reporter gene expression with EC50 values of 8 and 17 ng ml-1, respectively
