NO-donor properties, a series of "hybrid" 1,4-dihydropyridines (1,4-DHPs), bearing NO-donating furoxan moieties on the 3-positioned lateral ester chain were synthesized and pharmacologically characterized. Furazan analogues were also prepared and investigated for control purposes, because they are unable to release NO. METHODS Synthesis of the models was achieved by a modified Hantzsch approach. All of the
用途为了获得具有混合的Ca2 +通道拮抗和NO供体特性的新型心血管药物,一系列“混合”的1,4-二氢吡啶(1,4-DHP)在3位侧酯上带有NO供体的呋喃烷部分合成链并进行药理学表征。还制备并研究了呋喃山类似物用于控制目的,因为它们无法释放NO。方法通过改进的Hantzsch方法实现了模型的综合。通过Griess反应,在存在大量过量的半胱氨酸的情况下,评估了所有最终的呋喃喃1,4-DHPs产生亚硝酸盐的能力。评估大鼠主动脉上的血管舒张活性,并表示为EC50和EC50MB值,分别在不存在和存在亚甲基蓝(MB)的情况下获得,众所周知的鸟苷酸环化酶抑制剂。通过[3H]-硝苯地平对大鼠皮质匀浆的置换实验,确定了对Ca2 +通道上1,4-DHP受体的亲和力,以IC50值表示。结果某些杂化化合物(衍生物15a,15b,16a和16b)显示出血管舒张活性,主要取决于它们的Ca2 +通道阻滞剂特性。相比之下
