An effective synthesis of thymogen was developed. Conjugates of 2',3'-didehydro-3'-deoxythymidine (nucleoside d4T) with thymogen were prepared in which the nucleoside hydroxyl group was linked to the thymogen carboxyl group of either tryprophan or glutamic acid residues. It was shown that the anti-HIV activity of the d4T-thymogene conjugate with the tryptophan linkage was comparable to that of d4T, whereas its cytotoxicity was nil. The d4T-tryptophan conjugate also displayed high anti-HIV activity.
