tretinoin Tretinoin: An important regulator of GENE EXPRESSION during growth and development, and in NEOPLASMS. Tretinoin, also known as retinoic acid and derived from maternal VITAMIN A, is essential for normal GROWTH; and EMBRYONIC DEVELOPMENT. An excess of tretinoin can be teratogenic. It is used in the treatment of PSORIASIS; ACNE VULGARIS; and several other SKIN DISEASES. It has also been approved for use in promyelocytic leukemia (LEUKEMIA, PROMYELOCYTIC, ACUTE).. retinoic acid : A retinoid consisting of 3,7-dimethylnona-2,4,6,8-tetraenoic acid substituted at position 9 by a 2,6,6-trimethylcyclohex-1-en-1-yl group (geometry of the four exocyclic double bonds is not specified).. all-trans-retinoic acid : A retinoic acid in which all four exocyclic double bonds have E- (trans-) geometry. | 3.7 | 10 | 0 | retinoic acid; vitamin A | anti-inflammatory agent; antineoplastic agent; antioxidant; AP-1 antagonist; human metabolite; keratolytic drug; retinoic acid receptor agonist; retinoid X receptor agonist; signalling molecule |
retinol Vitamin A: Retinol and derivatives of retinol that play an essential role in metabolic functioning of the retina, the growth of and differentiation of epithelial tissue, the growth of bone, reproduction, and the immune response. Dietary vitamin A is derived from a variety of CAROTENOIDS found in plants. It is enriched in the liver, egg yolks, and the fat component of dairy products.. vitamin A : Any member of a group of fat-soluble retinoids produced via metabolism of provitamin A carotenoids that exhibit biological activity against vitamin A deficiency. Vitamin A is involved in immune function, vision, reproduction, and cellular communication.. all-trans-retinol : A retinol in which all four exocyclic double bonds have E- (trans-) geometry.. retinol : A retinoid consisting of 3,7-dimethylnona-2,4,6,8-tetraen-1-ol substituted at position 9 by a 2,6,6-trimethylcyclohex-1-en-1-yl group (geometry of the four exocyclic double bonds is not specified). | 2.67 | 3 | 0 | retinol; vitamin A | human metabolite; mouse metabolite; plant metabolite |
3,4-didehydroretinoic acid 3,4-didehydroretinoic acid: RN given refers to parent cpd; structure given in first source. all-trans-3,4-didehydroretinoic acid : A retinoid obtained by 3,4-desaturation of beta-ionone ring of all-trans-retinoic acid | 1.98 | 1 | 0 | retinoid; vitamin A | human xenobiotic metabolite |
retinaldehyde Retinaldehyde: A diterpene derived from the carotenoid VITAMIN A which functions as the active component of the visual cycle. It is the prosthetic group of RHODOPSIN (i.e., covalently bonded to ROD OPSIN as 11-cis-retinal). When stimulated by visible light, rhodopsin transforms this cis-isomer of retinal to the trans-isomer (11-trans-retinal). This transformation straightens-out the bend of the retinal molecule and causes a change in the shape of rhodopsin triggering the visual process. A series of energy-requiring enzyme-catalyzed reactions convert the 11-trans-retinal back to the cis-isomer.. all-trans-retinal : A retinal in which all four exocyclic double bonds have E- (trans-) geometry. | 2.03 | 1 | 0 | retinal; vitamin A | gap junctional intercellular communication inhibitor; human metabolite; mouse metabolite |
retinol palmitate retinol palmitate: RN given refers to parent cpd; structure. retinyl palmitate : A palmitate ester of retinol with undefined geometry about the C=C bonds.. all-trans-retinyl palmitate : An all-trans-retinyl ester obtained by formal condensation of the carboxy group of palmitic (hexadecanoic acid) with the hydroxy group of all-trans-retinol. It is used in cosmetic products to treat various skin disorders such as acne, skin aging, wrinkles, dark spots, and also protect against psoriasis. | 1.97 | 1 | 0 | all-trans-retinyl ester; retinyl palmitate | antioxidant; Escherichia coli metabolite; human xenobiotic metabolite |
4-oxoretinoic acid 4-oxoretinoic acid: RN given refers to cpd without isomeric designation; structure. all-trans-4-oxoretinoic acid : A retinoid that consists of all-trans-retinoic acid bearing an oxo substituent at position 4 on the cyclohexenyl ring. | 3.09 | 5 | 0 | enone; retinoid | human xenobiotic metabolite |
