The N-2′ position of the natural product emetine has been derivatized to thiourea, urea, sulfonamide, dithiocarbamate, carbamate and pH responsive hydrolysable amide analogs. In-vitro studies of these analogs in PC3 and LNCaP prostate cancer cell lines showed that the analogs are generally less cytotoxic (average IC50 ranging from 0.079 μM to 10 μM) than emetine (IC50 ranging from 0.0237 to 0.0329 μM). The pH sensitive sodium dithiocarbamate salt 13 and the amide analogs 21, 22, 26 (obtained from maleic and citraconic anhydrides) showed the most promise as acid-activatable prodrugs under mildly acidic conditions found in the cancer micro-environment. These prodrugs released 12 – 83% of emetine at pH 6.5 and 41 – 95% emetine at pH 5.5. Compounds 13 and 26 were further shown to exhibit increased cytotoxicity in PC3 cell culture media that was already below pH 7.0 at the time of treatment.
