NCI Drug Dictionary


A natural homologue of ribonuclease A isolated from the eggs of the frog Rana pipiens. Ranpirnase primarily degrades cellular transfer RNA with a substrate specificity for uridine-guanidine base-pair sequences, resulting in inhibition of protein synthesis and cytotoxicity. This agent also activates caspase-9 in mitochondria, resulting in tumor cell apoptosis. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus)
