title: Synthesis and antitumour activity of 4-nitroso-4-(2-chloroethyl)semicarbazides.
abstract: 1-Methyl-1-(2-chloroethyl)-4-nitroso-4-(2-chloroethyl)semicarbazide, 1,1-di-(2-chloroethyl)-4-nitroso-4-(2-chloroethyl)semicarbazide and 1,1-di-(2-bromoethyl)-4-nitroso-4-(2-chloroethyl)semicarbazide, which are a novel class of nitrosoureas containing hydrazinomustard residue, have been synthesized. A dose-dependent antitumour activity was found with the three tested compounds.
