S. Ozaki et al., 5-FLUOROURACIL DERIVATIVES - XXIII - SYNTHESIS AND ANTITUMOR ACTIVITIES OF 1-CARBAMOYL-5-FLUOROURACILS HAVING AROMATIC RING, Chinese journal of chemistry, 16(2), 1998, pp. 171-177
In order to get good antitumor agents especially better than 5-fluorou
racil, tegafur and 1-hexylcarbamoyl-5-fluorouracil (HCFU), fourty nine
1-carbamoyl-5-fluorouracil having aromatic ring were synthesized from
5-fluorouracil acid isocyanates or amines. Antitumor activity was tes
ted in the L-1210 tumor system, and 5 compounds gave better value of t
herapeutic ratio than Ei-fluorouracil, tegafur, HCFU, 1-(4-Methoxybenz
ylcarbamoyl)-5-fluorouracil gave the best result.
