Unique mechanism of action: Camptothecin can specifically inhibit topoisomerase I, which plays a key role in DNA replication, transcription and other processes. Camptothecin binds to topoisomerase I-DNA complex to form a stable ternary complex, which hinders the reconnection of DNA chains, causing DNA breakage, thereby inhibiting the proliferation of tumor cells. This mechanism of action is different from many traditional chemotherapy drugs, giving it unique anti-tumor activity.
Broad-spectrum anti-tumor activity: It has inhibitory effects on a variety of tumor cell lines, including lung cancer, colon cancer, gastric cancer, breast cancer, leukemia, etc. In preclinical studies and clinical trials, it has shown certain efficacy, providing the possibility of treating a variety of malignant tumors.
Natural source: As a natural product, compared with some fully synthetic chemical drugs, camptothecin has relatively good biocompatibility and lower toxic side effects. At appropriate doses, the damage to normal tissues is relatively small, and patients are more likely to tolerate it.
Xanthophyll is a carotenoid and a natural pigment. It is widely found in nature, especially in green vegetables, fruits, flowers and some algae. Lutein has important biological functions and plays an important role in maintaining normal physiological activities and health of the human body, especially in protecting the eyes.
The chemical name of camptothecin is 10-hydroxy-camptothecin, with a molecular formula of \(C_{20}\)\(H_{16}\)\(N_2\)\(O_4\) and a relative molecular mass of 348.35. It is a pentacyclic quinoline alkaloid, which contains a quinoline ring, a pyrrole ring and an α-hydroxy-lactone ring. This special structure is the basis of its biological activity.

Drug development: The unique structure and mechanism of action of camptothecin provide an important template for the development of new anti-tumor drugs. Scientists have developed a series of derivatives with better efficacy and pharmacokinetic properties by structural modification and transformation of camptothecin, which continuously promotes the development of anti-tumor drugs.
Basic research: As an important biological tool, camptothecin is also widely used in basic research fields such as cell biology and molecular biology. It can be used to study the mechanism of action of topoisomerase I in the process of DNA replication, transcription, and repair, as well as the biological behaviors of tumor cell proliferation and apoptosis, providing a powerful means for in-depth understanding of the molecular mechanism of tumor occurrence and development.
