ara-CMP alkyl esters (7a-e), given ip to the L1210 leukemic mice, were found to be toxic and ineffective. However, ara-CDP hexadecyl ester (9a) showed marginal activity (ILS, 38%). These preliminary results support the thesis that the ara-C conjugates of this type may require a lipophilic and naturally occurring moiety for improved efficacy.
