11-cisRetinol is an isomer of vitamin A . It is formed from vitamin A,viaatrans-retinyl ester intermediate, by the enzyme RPE65 in the retinal pigment epithelium and then converted to 11-cis retinal as part of the visual cycle.1,211-cisRetinol is an agonist of salamander and human red rod opsins expressed in COS cells and an inverse agonist of salamander red cone opsin, as well as human red and green cone opsins expressed in COS cells.3It promotes pigment formation in cone, but not rod, photoreceptors. 1.Rando, R.R.The biochemistry of the visual cycleChem.

Vitamin A-d4 是 Vitamin A 的氘代化合物。Vitamin A 的 CAS 号为 68-26-8。Retinol 及其衍生物,在视网膜的代谢功能、上皮组织的生长和分化、骨骼的生长、生殖和免疫反应中起重要作用。膳食维生素 A 来源于植物中发现的多种类胡萝卜素。它富含肝脏、蛋黄和乳制品的脂肪成分。
All-trans-13,14-Dihydroretinol, a metabolite of all-trans-retinoic acid, is synthesized through the enzymatic action of retinol saturase on all-trans-retinoic acid.
Retinyl oleate is A fatty acid ester formed from oleic acid and all-trans retinol (vitamin A) that is used in the preparation of oily acne treatment preparations.
RBP4 inhibitor 1 (compound 43b) is an orally active and potent inhibitor of retinol-binding protein 4 (RBP4), exhibiting IC50 values of 28 nM and 110 nM for human and mouse RBP4, respectively. It effectively reduces blood RBP4 levels in mice, providing a long-lasting effect [1].
IRBP651-670(Interphotoreceptor retinoid-binding protein (651-670))是IRBP(亦称为retinoid-binding protein 3)的肽段,参与色素再生,通过将视黄醇和视黄醛从光感受细胞传输到视网膜色素上皮。在C57BL 6小鼠中,利用IRBP651-670诱导自身免疫性葡萄膜炎,这些小鼠携带H-2b单体型。用IRBP651-670(300 µg 动物)免疫增加了小鼠眼部IL-1β、IL-6、IL-17、TNF-α和IFN-γ水平,免疫细胞浸润及光感受器损伤。
