As the part of the studies to clarify the interaction between 11-cis retinal and apoprotein opsin in the rhodopsin molecule, the retro-γ-retinal, possessing the dissected diene and trienal groups, has been investigated as a new chromophore in rhodopsin analogues. The syntheses, spectral properties of three retro-γ-retinal isomers [all-trans (VIIa), 11-cis (VIIa') and 9-cis (VIIb)] and some chemical behaviours of VIIb have been described. Of these three isomers, VIIb has given a new artificial visual pigment.
为了阐明 11-顺式视网膜素与犀牛蛋白分子中的载蛋白虹膜蛋白之间的相互作用,研究人员对具有二烯和三烯醛基团的逆-γ-视网膜素进行了研究,将其作为犀牛蛋白类似物中的一种新的发色团。研究描述了三种逆-γ-视网膜异构体[全反式(VIIa)、11-顺式(VIIa')和 9-顺式(VIIb)]的合成、光谱特性以及 VIIb 的一些化学行为。在这三种异构体中,VIIb 提供了一种新的人工视觉色素。
