Noscapine-13C-d3 is intended for use as an internal standard for the quantification of noscapine (Item No. 17255) by GC- or LC-MS. Noscapine is an alkaloid that has been found in opium and has anticancer and antitussive properties.1,2,3 It binds to tubulin and induces cell cycle arrest at the G2/M phase in HeLa cells when used at a concentration of 20 µM.2 Noscapine induces apoptosis in HeLa cells and thymocytes (IC50s = 25 and 10 µM, respectively) and reduces proliferation of MCF-7 breast and Renal 1983 bladder cancer cells (IC50s = 42.3 and 39.1 µM, respectively). In vivo, noscapine (120 mg/kg) induces tumor regression in an MCF-7 mouse xenograft model. Noscapine (30 and 70 mg/kg) decreases the number of citric acid-induced coughs in guinea pigs.3
