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.

Additional systemic treatments for locally advanced or metastatic pancreatic cancer are needed, as current treatment options produce only modest survival benefits. Rubitecan (Orathecin; Supergen Inc., Dublin, CA, http://www.supergen.com) is an orally active camptothecin derivative with demonstrated responses in patients with

Pharmacokinetics and lactone/carboxylate equilibrium of 9-Nitrocamptothecin (9-NC) were compared after intravenous (i.v.) and intramuscular (i.m.) injection at a dose of 1.5mg/kg 9-NC solution. The concentrations of three different forms of 9-NC, namely lactone, carboxylate and total 9-NC, were measured by

In this study, folate-conjugated polymer micelles were synthesized by mixing folate-poly(ethylene glycol)-distearoylphosphatidylethanolamine (FA-PEG-DSPE) and methoxy-poly(ethylene glycol)-distearoylphosphatidylethanolamine (MPEG-DSPE) to encapsulate anticancer agent 9-nitro-camptothecin (9-NC). Formulations were characterized by critical micellization concentration (CMC) values of copolymers, micelle particle size, zeta-potential, encapsulation efficiency

This study was designed to investigate in vitro release, in vivo tissue distribution and the damage to the lungs of 9-nitrocamptothecin (9-NC) liposomes. In vitro release of 9-NC from liposomes was carried out in phosphate buffer saline solution (PBS) pH
