  Cyclane-aminol 10-hydroxycamptothecin analogs as novel DNA topoisomerase I inhibitors induce apoptosis selectively in tumor cells

  摘要：

  A novel series of cyclane-aminol 10-hydroxycamptothecin (HCPT) analogs was designed and synthesized through the Mannich reaction using HCPT as the lead compound, such as 10-hydroxyl-9-L-prolinol (+) methylcamptothecin (PRPT), 10-hydroxyl-9-(4'-hydroxy) piperidinylmethylcamptothecin (PPPT), and 10-hydroxy-9(4'-hydroxyethyl)-piperazinylmethycamptothecin (QPPT). Three kinds of new cyclane-aminols were introduced into the structure of HCPT, which modified strong cytotoxic HCPT into cyclane-aminol HCPT analogs with moderate cytotoxicity and improved selectivity toward DNA topoisomerase I inhibition in tumor cells. Special metabolic pathways for cyclane-aminol HCPT analogs in rats were discovered, which differed from other HCPT analogs. Cyclane-aminol HCPT analogs can capture O-2(-) and cause an increase in intracellular hydrogen peroxide levels with selective induction of apoptosis in tumor cells rather than in normal peripheral blood mononuclear cells. Among them, PPPT has a much better druggability than topotecan (TPT) and has the potential to be developed into an antitumor agent.
