Nitric oxide (NO) is a key inter- and intracellular molecule involved in the maintenance of vascular tone, neuronal signaling, and host response to infection. The biosynthesis of NO in mammals involves a two-step oxidation of L-arginine (L-Arg) to citrulline and

N-Aryl-N'-hydroxyguanidines are compounds that display interesting pharmacological properties but their chemical reactivity remains poorly investigated. Some of these compounds are substrates for the heme-containing enzymes nitric-oxide synthases (NOS) and act as reducing co-substrates for the copper-containing enzyme Dopamine beta-Hydroxylase (DBH)

Conversion of neurotransmitter dopamine into norepinephrine is catalyzed by dopamine beta-hydroxylase (DbH). The reaction requires the presence of both molecular oxygen and a reducing cosubstrate, the assumed physiological cosubstrate being ascorbic acid. We have investigated the ability of a new

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
