Camptothecin (CPT), a kind of alkaloid, is a DNA topoisomerase I (Topo I) inhibitor with an IC₅₀ of 679 nM. Camptothecin (CPT) exhibits powerful antineoplastic activity against colorectal, breast, lung and ovarian cancers, modulates hypoxia-inducible factor-1α (HIF-1α) activity by changing microRNAs (miRNA) expression patterns in human cancer cells.

Topotecan Hydrochloride (SKF 104864A Hydrochloride) is a Topoisomerase I inhibitor with potent antineoplastic activities.

Irinotecan hydrochloride ((+)-Irinotecan hydrochloride) is a topoisomerase I inhibitor mainly used to treat colon cancer and rectal cancer.

(S)-10-Hydroxycamptothecin (10-HCPT;10-Hydroxycamptothecin) is a DNA topoisomerase I inhibitor of isolated from the Chinese plant Camptotheca accuminata. (S)-10-Hydroxycamptothecin exhibits a remarkable apoptosis-inducing effect. (S)-10-Hydroxycamptothecin has the potential for hepatoma, gastric carcinoma, colon cancer and leukaemia treatment.

Rubitecan (RFS 2000), a Camptothecin derivative, is an orally active topoisomerase I inhibitor with broad antitumor activity, and induces protein-linked DNA single-strand breaks, thereby blocking DNA and RNA synthesis in dividing cells.

3β-O-trans-Feruloyl-2α,23α-dihydroxy-urs-12-en-28-oic acid (Compound 3) is a pentacyclic triterpenoid found in the fruit of Camptotheca acuminata.

18-Hydroxycamptothecin is a camptothecin analogue that can be isolated from Camptotheca acuminata. Camptothecin compounds possess potential activities such as anti-cancer and anti-viral properties.

9-Aminocamptothecin (9-Amino-CPT) is a topoisomerase I inhibitor with potent anticancer activity.

9-Methoxycamptothecin (MCPT), isolated from Camptotheca acuminata, has antitumor activities through topoisomerase inhibition. 9-Methoxycamptothecin (MCPT) induces strong G2/M arrest and apoptosis in cancer.

7-Ethylcamptothecin is a derivative of Camptothecin (HY-16560) and a DNA topoisomerase I inhibitor that exhibits significant antitumor activity against tumor cells. 7-Ethylcamptothecin serves as a key precursor for the synthesis of 20 (S)-O-substituted benzoyl-7-ethylcamptothecin compounds. 7-Ethylcamptothecin is widely used in various tumor-related scientific studies.

Sodium Camptothecin is a plant alkaloid, with antitumor activity. Sodium Camptothecin is a reversible inhibitor of RNA synthesis. Sodium Camptothecin is an effective inhibitor of adenovirus replication. Sodium Camptothecin inhibits DNA synthesis and causes breaks in intracellular preformed viral DNA.

(±)-10-Hydroxycamptothecin is an indole alkaloid that inhibits the activity of topoisomerase I and has a broad spectrum of anticancer activity.

Picein is an antioxidant and anti-inflammatory agent. Picein can be isolated from the leaves of Picrorhiza kurroa. Picein reduces MDA levels and increases the levels of SOD, GPX and TAC. Picein alleviates oxidative stress and promotes bone regeneration in osteoporotic bone defects by inhibiting Ferroptosis (via activation of the Nrf2/HO-1/GPX4 pathway). Picein prevents scopolamine (HY-N0296)-induced passive avoidance memory impairment in rats. Picein can be used in research related to osteoporotic bone defects and Alzheimer's disease.

10-Methoxycamptothecin is a natural bioactive derivative of camptothecin (CPT) isolated from Camptotheca acuminata, and has been confirmed to possess high anti-cancer properties. 10-Methoxycamptothecin has higher cytotoxicity than 10-hydroxycamptothecin by testing antitumor activity against 2774 cell lines.

20-O-Acetylcamptothecin (O-Acetylcamptothecin) is a derivative of Camptothecin (HY-16560) and an inhibitor of Topoisomerase I.
