CARBO-ACYCLIC NUCLEOSIDE DERIVATIVES AS ANTIVIRAL AND ANTINEOPLASTIC AGENTS

摘要

The present invention is directed to a class of novel carbo-acyclic derivatives having formulas (I) and (II) and their use as anti-viral and anti-neoplastic agents, wherein X1 and X2 are each independently hydrogen, fluorine, or chlorine, R is hydrogen or hydroxymethyl, J is a radical of formulas (a), (b) and (c). Y1 is a CH group, a CCl group, a CBr group or a CNH2 group, Y2 and Y3 are each independently nitrogen or a CH group, Y1 is a CH group, a CCl group, a CBr group or a CNH2 group, Y2 and Y3 are each independently nitrogen or a CH group, Y4 is hydrogen, C1-C4 alkyl, C1-C4 alkoxy or halogen, Y5 is NH2 or C1-C4 alkoxy, Q is NH2, NHOH, NHCH3, OH, or hydrogen, and V is hydrogen, halogen or NH2; or a pharmaceutically acceptable salt thereof.
