Twenty four 1-[2-alkylthio-5-(azol-2 or 5-yl)-4-chlorobenzenesulfonyl]-3-hydroxyguanidines 6a-x have been synthesized in order to evaluate their biological activity. Compounds 6a, 6c, 6d, 6f, 6g, 6i-p, 6r-t, and 6v-x were tested for their in vitro anticancer activity at the US National Cancer Institute. The

Nitric oxide (NO) is a potent intra- and intercellular messenger involved in the control of vascular tone, neuronal signalling and host response to infection. In mammals, NO is synthesized by oxidation of l-arginine catalysed by hemeproteins called NO-synthases with intermediate
