A series of Na-acyl derivatives of L-cystine-bis [N,N-di(2-chloroethyl)]dihydrazide was synthesized. The effect of the acyl substituent on the antitumour activity of the synthesized compounds was studied. It was demonstrated that the introduction of short-chain Na-acyl substituents resulted in substances with higher antitumour effect and lower toxicity.
