A new series of 2-alkyloxy-pyridine-3-carbonitrile-benzofuran hybrids (4a-x) was synthesized. All the new derivatives were examined via the standard technique for their vasodilation activity. Some of the investigated compounds exhibited a remarkable activity, with compounds 4w, 4e, 4r, 4s, 4f and 4g believed to be the most active hits in this study with IC50 values 0.223, 0.253, 0.254, 0.268, 0.267

生物的血管舒张活性。一些被研究的化合物表现出显着的活性,化合物4w,4e,4r,4s,4f和4g被认为是该研究中最活跃的命中化合物,IC50值分别为0.223、0.253、0.253、0.254、0.268、0.267和0.275 mM分别与所使用的参考标准
胺碘酮盐酸盐进行比较(IC50 = 0.300 mM)。使用CODES
