The synthesis and physicochemical parameters of a series of N4-(N,N-dialkyl)formamidine derivatives of 2'-deoxycytidine (dCyd, 1) and arabinocytidine (ara-C, 2), as prodrug prototypes, are described. The lipophilicity of the formamidine derivatives compared to that of the parent nucleosides increased 1.26- to 145-fold. The corresponding half-lives of the derivatives in aqueous solution at pH 7.4 and
