We evaluated the viability of 1α,25-dihydroxyvitaminD 3 -3β-[N-(4-azido-2-nitrophenyl)glycinate] (1,25-(OH) 2 -D 3 -ANG), an analog of 1α,25-dihydroxyvitamin D 3 (1,25-(OH) 2 -D 3 ) as a photoaffinity probe for 1,25-(OH) 2 -D 3 receptor in chick i

A simple method for production of antisera with high affinity and selectivity for 1 alpha, 25-dihydroxyergocalciferol and 1 alpha, 25-dihydroxychole-calciferol is described. 1 alpha-Hydroxy-25,26,27-trisnorcholecalciferol-24-oic acid was coupled dire

2,3,4-Tri- O -benzyl ( 11 ) and 2,3,6-tri- O -benzyl ( 12 ) -1-thio- D -glucopyranose were prepared as intermediates for the synthesis, by the thioglycoside scheme, of(1→6)- and (1→4)-linked oligosaccharides of D -glucose. The 6-hydroxyl isomer 1

Cutaneous 7-dehydrocholesterol, exposed to ultraviolet radiation, converts to previtamin D3, which in turn converts in skin to vitamin D3 and is carried into the circulation. We investigated the feasibility of the photochemical conversion in skin of

3-Epivitamin D3, the 3 alpha epimer of vitamin D3, was synthesized, and its biological activity in the rat was evaluated. It was found to be approximately 4 times less active on a weight basis than vitamin D3 with respect to intestinal calcium transp

The process of the photolytic activation of vitamin D precursor(s) in the skin has been elucidated by a detailed analysis of the products formed after ultraviolet light exposure. The photolytic product isolated from the skin of rats exposed to ultrav

A pathway has been described in the skin for the synthesis of 24-dehydrovitamin D3 (delta 24D3) from 24-dehydroprovitamin D3. The physiologic function of delta 24D3 is unknown, but has been proposed as a potential inhibitor of hepatic vitamin D-25-hy

Reaction of 1-α-methylsulphonyloxy or 1-α-(p-tolylsulphonyloxy) derivatives of vitamin D3-acetate with KSAc in dimethyl sulphoxide resulted exclusively in 19-acetylthiolation; the same reaction with 1-α-p-tolylsulphonyloxy-(6R)-methoxycyclovitamin
