SM Herbals is the manufacturer of Camptothecin. SM Herbals specializes in the Extraction, Isolation and Purification of Phytochemicals. Camptothecin is a quinoline-based alkaloid. It is the only naturally-occurring DNA topoisomerase I inhibitor and is one of the newest chemo-therapeutic agents available today. Since Camptothecin causes a large number of side effects, its value lies in the production of chemically-related analogues with less toxicity and enhanced therapeutic potency. Topotecan and Irinotecan are anti-cancer drugs approved by the FDA and used to treat ovarian, lung and colon cancer.
