Description
Curator's Comment: description was created based on several sources, including https://www.ncbi.nlm.nih.gov/pubmed/16596197

10-Hydroxycamptothecin (10-HCPT), an indole alkaloid isolated from a Chinese tree, Camptotheca acuminate, inhibits the activity of topoisomerase I and has a broad spectrum of anticancer activity in vitro and in vivo. However, its use has been limited due to its water-insolubility and toxicity with i.v. administration. Prolonged elimination of 10-HCPT in vivo may have a significant impact on its therapeutic effects. 10-HCPT is metabolized to its carboxylate form and glucuronides.It was investigated that relatively low dose of 10-HCPT is able to inhibit the growth of colon cancer, facilitating the development of a new protocol of human trials with this anticancer drug.

Sample Use Guides

mice: 10-Hydroxycamptothecin (10-HCPT) was administered via p.o. once per two or four days at doses of 1, 2.5, 5, 7.5 mg/kg (volume of injection: 0.1 ml/20 g of body weight), respectively. The control group received propylene glycol vehicle once per two days.
Route of Administration: Oral
The effect of 10-HYDROXYCAMPTOTHECIN (10-HCPT) on the proliferation activity of RAW264.7 cells was detected using Cell Counting Kit-8 (CCK-8). CCK-8 detection showed that 10-HCPT with a certain concentration (1 ng/ml to 5 ng/ml) had no effect on cell proliferation (P>0.05); 10-HCPT could inhibit the generation of osteoclasts. With the increase of the concentration of 10-HCPT, the number of osteoclasts generated from cells cultured with 10-HCPT [1 ng/ml (86±11.14), 2 ng/ml (66.67±7.51), 5ng/ml (27.67±6.51)] was much lower than that of the control group (145±8.19), and the difference was statistically significant (all P=0, P less than 0.05).
