海关编码:2941900000 毒害物质数据:23214-92-8(Hazardous Substances Data) 毒性:An anthracycline cytotoxic antineoplastic that is produced by Streptomyces peucetius. The LD50 in mice is 9.4 mg/kg, i.v. It is a carcinogen that inhibits DNA and RNA synthesis by intercalating in double-stranded DNA with the amino sugar in the minor groove and the 90-OH group of the anthracycline ring hydrogen-bonded to the adjacent guanine. It also alters membrane fluidity and ion transport, and generates free radicals through a cytochrome P450-mediated reductive process. In humans, it causes alopecia, stomatitis, nausea, vomiting, diarrhea, cardiotoxicity (manifested by tachycardia), and potentially fatal congestive heart failure.
