nc-190 and Carcinoma--Small-Cell

CPT-11 and Topotecan are a new semisynthetic derivative of CPT, and have been shown to inhibit DNA topoisomerase I and to have a strong antitumor activity with low toxicity against murine tumor. On the other hard, the new antitumor compounds, NC-190 and IST-622 have been shown to inhibit DNA topoisomerase II, and the clinical study are currently under progress. A phase II study of CPT-11 demonstrated that CPT-11 was a very active agent which a acceptable toxicities against patient with advanced non-small cell lung cancer and small cell lung cancer.
