Common NameSafracin B
DescriptionSafracin B is a semisynthetic precursor belonging to the chemical class of saframycins, which are a family of antibiotics. Its chemical structure is characterized as 21-hydroxysafracin A, which is derived from the biosynthetic pathways of saframycin antibiotics. The biosynthesis of safracin B involves key enzymes such as SacD, a heme-containing peroxidase that plays a role in its production alongside other enzymes like SfmD. These enzymes are crucial for the activation and refactoring of biosynthetic gene clusters (BGCs) to enhance the yield of safracin B, which has been noted for its potential as an anti-cancer agent, particularly as a precursor for the drug ET-743 (PMID:38561780 ). While the biosynthetic mechanisms of safracin B and its analogs like SFM-A are distinct, they likely share similarities in their pathways (PMID:17981978 ). Notably, safracin B exhibits a higher therapeutic index compared to safracin A, demonstrating lower toxic and effective doses, and has been shown to significantly prolong the lifespan of tumor-bearing mice (PMID:4019320 ).
