calcitriol dihydroxy-vitamin D3: as a major in vitro metabolite of 1alpha,25-dihydroxyvitamin D3, produced in primary cultures of neonatal human keratinocytes | 2.4 | 2 | 0 | D3 vitamins; hydroxycalciol; triol | antineoplastic agent; antipsoriatic; bone density conservation agent; calcium channel agonist; calcium channel modulator; hormone; human metabolite; immunomodulator; metabolite; mouse metabolite; nutraceutical |
vitamin d 2 Ergocalciferols: Derivatives of ERGOSTEROL formed by ULTRAVIOLET RAYS breaking of the C9-C10 bond. They differ from CHOLECALCIFEROL in having a double bond between C22 and C23 and a methyl group at C24.. vitamin D2 : A vitamin D supplement and has been isolated from alfalfa. | 3.08 | 5 | 0 | hydroxy seco-steroid; seco-ergostane; vitamin D | bone density conservation agent; nutraceutical; plant metabolite; rodenticide |
cholecalciferol Cholecalciferol: Derivative of 7-dehydroxycholesterol formed by ULTRAVIOLET RAYS breaking of the C9-C10 bond. It differs from ERGOCALCIFEROL in having a single bond between C22 and C23 and lacking a methyl group at C24.. calciol : A hydroxy seco-steroid that is (5Z,7E)-9,10-secocholesta-5,7,10(19)-triene in which the pro-S hydrogen at position 3 has been replaced by a hydroxy group. It is the inactive form of vitamin D3, being hydroxylated in the liver to calcidiol (25-hydroxyvitamin D3), which is then further hydroxylated in the kidney to give calcitriol (1,25-dihydroxyvitamin D3), the active hormone. | 1.97 | 1 | 0 | D3 vitamins; hydroxy seco-steroid; seco-cholestane; secondary alcohol; steroid hormone | geroprotector; human metabolite |
1,25-dihydroxyergocalciferol 1,25-dihydroxyergocalciferol: RN given refers to (3beta,5Z,7E,22E)-isomer. 1alpha,25-dihydroxyvitamin D2 : A hydroxycalciol that is vitamin D2 bearing additional hydroxy substituents at positions 1alpha and 25. | 1.97 | 1 | 0 | hydroxycalciol; seco-ergostane; vitamin D | bone density conservation agent; human xenobiotic metabolite; nutraceutical |
24,25-dihydroxyvitamin d2 24,25-dihydroxyvitamin D2: metabolite of vitamin D2; RN given refers to (3beta,5Z,7E,22E)-isomer | 6.95 | 1 | 0 | | |
1,24-dihydroxyvitamin d2 1,24-dihydroxyvitamin D2: LR-103 has antineoplastic activity; RN & structure in first source | 7.39 | 2 | 0 | | |
