Camptothecin is the core active ingredient of the only TOP I inhibitor class of anti-tumor drugs in clinical use. The domestic market is growing at over 15% annually, with sustained demand growth in the treatment of colorectal cancer, gastric cancer, and other indications.

Longzangmetacell has achieved stable large‑scale production of camptothecin through directed cultivation of Nothapodytes stem cells combined with a high‑efficiency extraction process. With 500L fermenters, the single‑batch yield reaches 1.02 kg per month, completely eliminating reliance on natural plant cultivation. Energy consumption, labor costs, and overall production costs have been significantly reduced.

The product offers high purity and stable quality, making it suitable for high‑end anti‑tumor drug formulations as well as marine antifouling agents. Longzang has established joint development and supply agreements with pharmaceutical companies, ensuring a clear commercialization path and substantial market potential.
