Shanghai Ruifu Chemical Co., Ltd. is the leading manufacturer and supplier of 7-Ethyl-10-Hydroxycamptothecin (CAS: 86639-52-3) with high quality. 7-Ethyl-10-Hydroxycamptothecin (CAS: 86639-52-3) is an active metabolite of the Topoisomerase I inhibitor Irinotecan. SN-38 (NK012) inhibits DNA and RNA synthesis with IC50s of 0.077 and 1.3 μM, respectively. 7-Ethyl-10-Hydroxycamptothecin (SN-38), is the active metabolite of Irinotecan, a semisynthetic derivative of camptothecin, a quinoline-based alkaloid found in the bark of the Chinese camptotheca tree and the Asian nothapodytes tree. Although 7-Ethyl-10-Hydroxycamptothecin is up to 1,000 times more potent than Irinotecan, it has not been converted into a viable drug candidate because it is insoluble. It is presently being subjected to clinical trials in combination with other moieties which may ultimately allow it to be efficacious as an antineoplastic drug.
