Biochem/physiol Actions

Topoisomerase I inhibitor. Rubitecan induces protein- linked DNA single strand breaks, blocking DNA and RNA synthesis in dividing cells. This mode of action makes rubitecan a potential chemotherapeutic agent, and it has been used with some success against refractory pancreatic cancer.

9-Nitro-20(S)-camptothecin (9-NC) has achieved remarkable curative effect in anticancer research. However, the clinical application of 9-NC is largely hampered by its poor solubility and stability. In this paper, novel amphiphilic block copolymers derived from d,l-lactide, trimethylene carbonate, and methylated poly(ethylene

9-Nitrocamptothecin (9-NC) is an orally administered topoisomerase-I inhibitor for the treatment of pancreatic carcinoma, but its oral absorption and bioavailability are poor. The main objective of this study was to develop optimal 9-nitrocamptothecin (9-NC) microemulsion prepared by self-microemulsifying drug delivery
