title: [Effect of N-(6-aminohexyl)-5-chloronaphthalene-1-sulfamide (W-7) and its analogs on the activity of soluble guanylate cyclase and on human platelet aggregation].
abstract: The effect of N-(omega-aminoalkyl) derivatives of naphthalene-1-sulfamide on the activity of soluble guanylate cyclase and on human platelet aggregation at the first (reversible) step of the guanylate cyclase reaction was studied. Low (approximately 10(-7)-10(-6) M) concentrations of the above compounds were shown to stimulate the guanylate cyclase activity; some derivatives caused simultaneous inhibition of platelet aggregation induced by ADP. Some fragments of the chemical structure of the molecules responsible for the enzyme activity regulation in the tested systems were identified. The naphthalene-1-sulfamide derivatives carrying 6-aminohexyl or 8-amino-octyl groups of the sulfamide substituent as well as chlorine atom at positions 4 or 5 of the naphthalene ring appeared to be the most potent activators of platelet guanylate cyclase and inhibitors of platelet aggregation at the reversible step of the enzymatic reaction.
