Application
7-Ethylcamptothecin: A Water Insoluble Topoisomerase-I Inhibitor
7-Ethylcamptothecin (SN-22) is a water insoluble derivative of camptothecin [C1495] with broad antitumor activity. 7-Ethylcamptothecin has been converted into water soluble derivatives such as irinotecan hydrochloride [I0714]. Camptotecin and its derivatives interfere with DNA synthesis by inhibiting the enzyme topoisomerase-I. In order to prevent and correct of topological problems caused by the DNA double helix, topoisomerase-I catalyzes the relaxation of negatively supercoiled DNA, the knotting and unknotting DNA and the linking complementary rings of single-stranded DNA into double-stranded rings. Then the inhibition action induces breaks in single strand DNA. Eventually, this leads to double-strand DNA breaks and apoptosis or cell death.
