subsequently its biological activity. To address this source of variability, synthetic retinoid analogues have been designed and synthesised that retain stability during use and maintain biological function in comparison to ATRA. It is also shown that subtle modifications to the structure of the synthetic retinoid compound impacts significantly on biological activity, as when exposed to cultured human pluripotent
全反式维甲酸(ATRA)及其相关类似物是神经系统发育过程中细胞分化和功能的重要介体。众所周知,ATRA可以诱导人多能干细胞分化为神经组织。然而,并不总是意识到,ATRA在溶液中时高度易受异构化的影响,这会影响ATRA的有效浓度并进而影响其生物学活性。为了解决这种可变性的来源,已经设计并合成了合成类维生素A类似物,与ATRA相比,它们在使用过程中保持稳定性并保持生物学功能。还表明,对合成类维生素A化合物的结构进行细微修饰会显着影响其生物活性,当暴露于培养的人多能干细胞时,合成类维生素A 4-(5,5,8,8-四甲基-5,6,7,8-四氢萘-2-基乙炔基)苯甲酸4a(对位异构体)诱导神经分化类似于ATRA。相反,暴露于合成类视黄醇3-(5,5,8,8-四甲基-5,6,7,8-四氢萘-2-基乙炔基)苯甲酸4b(元异构体)的干细胞产生的神经元很少。和大量的上皮样细胞。用于此类合成类维生素A化合物的
