Various O-alkyl derivatives of 2′-deoxy-5-fluorouridine (FUdR) were synthesized and their antitumor activities in mice bearing sarcoma 180 (s.c.-p.o.) were evaluated in terms of the ED50 values (mg/kg/d). Most of these compounds were superior to FUdR in antitumor activity. In particular, the antitumor activity of 3′-O-(p-chlorobenzyl)-FUdR (3e) (ED50 = 0.87 mg/kg/d) was as much as 100 times that of FUdR (ED50 = 84 mg/kg/d). Further, various 5′-O-aminoacyl derivatives of 3e were synthesized and evaluated in terms of ED50 value and therapeutic index (T.I.). Both the ED50 value (0.41 mg/kg/d) and the T.I. (4.18) of 3′-O-(p-chlorobenzyl)-5′-O-glycyl-FUdR hydrochloride (6a) were significantly improved, compared with those of 3e and FUdR. FUdR plasma concentration after a single p.o. dosing of 6a was maintained for as long as 24 h.

An anticancer compound is disclosed which is represented by the formula STR1 wherein one of R1 and R2 is a phenyl-lower alkyl optionally having a substituent, phenyl-lower alkenyl or naphthyl-lower alkyl, the other of R1 and R2 is hydrogen or acyl, and R3 is hydrogen, acyl or tetrahydrofuranyl, or represented by the formula STR2 wherein Rx is an optionally substituted pyridyl, Y is arylene and α is a known 5-fluorouracil derivative residue which can be converted to 5-fluorouracil in vivo and which is linked to the carbonyl by an ester or amide linkage.
