Cyanostatin B

Cyanostatin B, a cyanobacterial lipopeptide, is a leucine aminopeptidase M (LAP) inhibitor (IC50 = 12 ng/mL) . Cyanostatin B is a weak inhibitor of protein phosphatase (PP2A) and also exhibits weak inhibitory activity against angiotensin-converting enzyme (ACE), with an IC50 value of 130 μg/mL. Cyanostatin B demonstrates both cytotoxic and genotoxic effects on human hepatocytes, although non-toxic to Artemia salina. Cyanostatin B inhibits the proliferation of HepG2 cells, induces DNA single-strand breaks, and causes genomic instability.[1][2].
