摘要: Camptothecin (CPT) compounds are one of the newer classes anticancer agents introduced over past decade. Early investigational trials with parent compound, CPT, derived from bark Camptotheca accuminata tree, was into clinical in late 1970s. Because its poor water solubility, CPT formulated sodium bicarbonate, which opened 20(S) lactone ring and caused significant toxicity inconsistent activity. Hence, development camptothecin as an agent halted (1).
