Novel phosphorothioamidates of pyrimidine nucleoside analogues have been prepared and evaluated in vitro against RKO human colon cancer cell by the MTT cytotoxicity assay. The parent nucleoside analogues were inactive in this assay, while the phosphorothioamidate prodrugs were active at low uM levels in some cases. The O-isopropyl phosphorothioamidate of 2,3-O-isopropylidene-uridine containing the L-phenylalanine ethyl ester 6f was the most active at 148 uM, a 10-fold enhancement in anticancer activity compared with the parent nucleoside 2 with no increase in cytotoxicity.
