    aspirin is joined by an ester linkage to furoxan moieties, with different ability to release NO, were synthesized and tested for NO-releasing, antiinflammatory, antiaggregatory, and ulcerogenic properties. Related furazan derivatives, aspirin, its propyl ester, and its gamma-nitrooxypropyl ester were taken as references. All the products described present an antiinflammatory trend, maximized in derivatives

    resulting hybrids displayed different pharmacological behaviors. When the 4-furoxanylcarbonyl system, bearing an ester or an amide function at the 3-position, was present (derivatives 7a,b), hybrids with predominant alpha 1-antagonist activity were obtained. By contrast, in the derivative 7c, in which the nitrile function is linked to the 3-position of the furoxan ring, the NO-mediated vasodilating properties
    在一个分子中存在两个不同药效基团的新血管扩张剂衍生物的设计,一直是通过用NO-前药呋喃酮部分替代众所周知的α1-受体拮抗剂普拉唑辛中的呋喃基羰基功能来进行的。目的是获得新的降压药,其中两种血管舒张机制(α1拮抗剂和NO介导)可以在适当的平衡中起作用。在有和没有氧合血红蛋白(HbO2)(一种著名的一氧化氮清除剂)存在下,对大鼠主动脉条上的α1-拮抗剂活性进行了评估。所得杂种表现出不同的药理行为。当存在在3位带有酯或酰胺官能团的4-呋喃氧羰基羰基系统(衍生物7a,b)时,获得了具有主要α1-拮抗剂活性的杂种。相反,在腈官能团与呋喃喃环的3位连接的衍生物7c中,NO介导的血管舒张特性占主导。最后,(呋喃基磺酰基)哌啶衍生物13a,b在适当的平衡下显示出没有血管舒张作用和α1-拮抗剂活性。对于呋喃喃衍生物,还讨论了在K(+)去极化的主动脉条上评估的NO依赖性血管舒张能力,以及在硫醇辅因子作用下NO

    Purpose. A series of derivatives having a propranolol-like moiety linked to NO-donor furoxan substructures were synthesized. The main objective of this investigation was to obtain agents with mixed No-dependent vasodilating and beta-blocking activities.Methods. Most of the target compounds were synthesized from the appropriate furoxans bearing XCH2CH2NH2 (X = O, S, SO2) chains at the 4 position of the ring, using AI(C2H5)(3) in methylene chloride solution and (+/-)2,3-epoxypropyl 1-naphtyl ether. Two of the final products (X = CONH) were obtained by coupling the appropriate furoxancarboxylic acids with N-[2-hydroxy-3-(1-naphthoxy)propyl]ethylenediamine. beta(1)- and beta(2)-blocking activities were examined on isolated guinea pig right atria and on guinea pig trachea respectively. Vasodilating properties were assessed on endothelium denuded strips of rat aortaResult. Some derivatives behave as well balanced "hybrids" displaying NO-dependent vasodilating and beta-blocking properties in the same concentration range. Some others display either prevalent beta-blocking or vasodilating activity. Generally speaking hybrid formation lowers the affinity for beta-receptors, in particular for beta(2)-type, to give an increase in beta(1)/beta(2) selectivity.Conclusions. The furoxan system is a flexible tool in designing analogues of propranolol whose NO-donating and beta-blocking properties are modulated over a wide range.
  • Synthesis of secondary and tertiary aminofurazans

    Reactions of nitrofurazans with primary and secondary amines were studied. Conditions were found which allow the efficient replacement of the nitro group with these nucleophiles. Transformations of the amidoxime fragment, which is bound to the furazan ring and contains an amino substituent, enable one to substantially expand the spectrum of polyfunctional derivatives. The structures of the amines synthesized were studied by X-ray diffraction analysis.
