Bleomycin A5 (Pingyangmycin) hydrochloride is a glycopeptide antibiotic with multiple biological activities, which can be isolated from Streptomyces. Bleomycin A5 hydrochloride exerts cytotoxic effects by binding to Fe2+ to form a complex, inducing single-strand and double-strand DNA breaks, and inhibiting DNA replication. Bleomycin A5 hydrochloride inhibits Drp1-mediated mitochondrial fission and suppresses PINK1/Parkin pathway-mediated mitophagy, ultimately triggering mitochondria-mediated cellular apoptosis. Bleomycin A5 hydrochloride can be used in cancer research[1][2][3][4][5].
