Provided are a novel compound having skin-whitening, anti-oxidizing and PPAR activities and a medical use thereof, and the compound has skin-whitening activities for the suppression of tyrosinase, and accordingly, is useful for use in skin-whitening pharmaceutical composition or cosmetic products; has anti-oxidant activities, and accordingly, is useful for the prevention and treatment of skin-aging; and has PPAR activities, and in particular, PPARα and PPARγ activities, and accordingly, is useful for use in pharmaceutical compositions or health foods which are effective for the prevention and treatment of obesity, metabolic disease, or cardiovascular disease.
nitro derivatives were potent, and exhibited a concentration- and partial endothelium-dependent vasorelaxant effects, with EC50s <5 μM. 2-Methoxy-4-[5-nitro-1H-benzo[d]imidazol-2-yl]phenol (compound 13) was the most potent derivative of the series, showing an EC50 value of 1.81 μM and Emax of 91.7% for ex vivo relaxant response in intact aortic rings, resulting in a 2.5-fold higher activity compared
使用短合成路线合成了一系列在5位被–CF 3或–NO 2取代的1 P苯并本的1 H-苯并[ d ]咪唑类似物。所有硝基衍生物均有效,并表现出浓度依赖性和部分内皮依赖性血管舒张作用,EC 50 s <5μM。2-甲氧基-4- [5-硝基-1 H-苯并[ d ]咪唑-2-基]苯酚(化合物13)是该系列中最有效的衍生物,其EC 50值为1.81μM,E max完整的主动脉环中离体舒张反应的抗氧化活性为91.7%,与Pimobendan相比,活性提高了2.5倍。密切相关的5-CF 3类似物(化合物8)的效价比13低19倍。使用自发性高血压大鼠(SHR)在25、50和100 mg kg -1的剂量下评估了化合物13的抗高血压活性,显示出统计学上显着的剂量依赖性效应。
