  Synthesis and cytotoxic activity of 5-(1-hydroxy-2-haloethyl)-, 5-oxiranyl- and (E)-5-(2-iodovinyl)-2,4-dichloro (or dimethoxy) pyrimidines

  摘要：

  A series of 5-(1-hydroxy-2-haloethyl) 6, 7, 13, 14a, 5-oxiranyl 8, 9 and (E)-5-(2-iodovinyl)-2,4-dichloro(or dimethoxy)pyrimidines 11, 12 were synthesized for evaluation as cytotoxic agents. The nuclear C-2 and C-4 substituents were determinants of activity since the 2,4-dichloro compounds 6, 8 and 11 were more potent (ED50 = 0.2-0.3-mu-g/ml) than the corresponding 2,4-dimethoxypyrimidine analogues 7, 9 and 12 (ED50 = 4-28-mu-g/ml), relative to melphalan (ED50 = 0.15-mu-g/ml), in the in vitro L1210 screen. Within the 2,4-dichloro series of compounds 6, 8 and 11, the C-5 substituent was not a determinant of activity. In contrast, in the 2,4-dimethoxypyrimidine series, the C-5 substituents influenced activity significantly where the relative potency order was oxiranyl 9 > -CH(OH)CH2I 7 > (E)-CH = CHI 12 > CH(OH)CHI2 13, CH(OH)CHBr(I) 14a and CH(Br)CHOH(I) 14b. The most active compound (E)-5-(2-iodovinyl)-2,4-dichloropyrimidine 11 exhibited weak activity in the in vivo P388 screen (% T/C = 116 for a 10 mg/kg ip dose) relative to the reference drug 5-fluorouracil (% T/C = 135 for a 20 mg/kg dose).
