✦ Synopsis

Twelve ethoxycarbonyl or phenylsulfonyl derivatives as prodrugs of hydroxylamine or phenylhydroxylamine were prepared and tested for antiplatelet (in vitro, Born test) antithrombotic (in vivo thrombosis model), and antihypertensive (in vivo, SHR rats) effects. In the Born test N,N-bisphenylsulfonylhydroxylamine (10) was most active (IC50 = 11 mumol/L). The N-ethoxycarbonyl-phenylhydroxylamine (7) was the most potent antithrombotic compound. It inhibited the thrombus formation in mesenteric arterioles of rats by 39% after a single p.o. dose of 60 mg/kg. Compound 7 lacked any antihypertensive activity. It, therefore, had been possible to separate completely the antithrombotic activities from antihypertensive properties in suitable hydroxylamine derivatives.

Reaktion von Quadratsauredimethylester (1) mit aquimolaren Mengen substituierter Hydroxylamine ergibt 3-Hydroxyamino-4-methoxy-3-cyclobuten-1 ,2-dione 2. Bei Umsetzung von Quadratsauredichlorid mit Hydroxylaminen werden Desoxygenierungsreaktionen beobachtet
