  (2R,3R,4S)-4-amino-3,4-dihydro-2-dimethoxymethyl-3-hydroxy-2-methyl-6-nitro-2H-1-benzopyran 在 三乙胺 作用下， 以 N,N-二甲基甲酰胺 、 异丙醇 为溶剂， 生成 (2R,3R,4S)-N''-cyano-N-(6-nitro-3,4-dihydro-3-hydroxy-2-methyl-2-dimethoxymethyl-2H-benzopyran-4-yl)-N'-(4-methoxybenzyl)guanidine

  A Novel Anti-Ischemic ATP-Sensitive Potassium Channel (K_ATP) Opener without Vasorelaxation:  N-(6-Aminobenzopyranyl)-N‘-benzyl-N‘ ‘-cyanoguanidine Analogue

  摘要：

  This paper describes the design, synthesis, and biological evaluation of a novel anti-ischemic compound, (2S,3S,4R)-N-(6-amino-3,4-dihydro-2-dimethoxymethyl-3-hydroxy-2-methyl-2H-benzopyranyl)-N'-benzyl-N " -cyanoguanidine (33), and the structure-activity relationships leading to the discovery of this compound. Compound 33 significantly reduced the myocardial infarct zone to area at risk (IZ/AAR) in the ischemic myocardium rat model with high cardioselectivity. Since the cardioprotective effect of compound 33 is reversed by ATP-sensitive potassium channel (K-ATP) blockers, its anti-ischemic effect appears to be at least mediated by K-ATP opening. In addition, compound 33 shows good protective activity on neuronal cells against oxidative stress, and therefore it is suggested that compound 33 may have therapeutic potential both in cardio- and in neuroprotection.
