產品描述：
24, 25-dihydroxyvitamin D3 [24,25(OH)2D3] is a Vitamin D (VD [1]) analogue that can inhibit some metabolic processes. It dose-dependently inhibited the intracellular 10-mM-Ca2+-evoked Ca2+-concentration-increase in enterocytes with an EC50 of 4.9 nM [2].

Vitamin D is important in calcium homeostasis, skeleton maintenance, and skeleton development. Two successive reactions are involved in the formation of VD: first the formation of 25-hydroxyvitamin D (25OHD); and second the formation of 1α, 25-dihydroxyvitamin D [1, 25(OH) 2D], the active hormonal vitamin D [3].

Ca2+ at 10 mM typically increased [Ca2+]i to a new stable value of 264 ± 16 nM from the basal value of 203 ± 13 nM. 24R, 25(OH)2D3 at concentrations from 0.2 pM to 202 nM dose-dependently inhibited the initial [Ca2+]i increase during the first 18 s (t= 300 to 318 s) and the final [Ca2+]i increase (t= 550 to 600 s), with EC50 values of 4.9 nM and 30 nM, respectively. 24R, 25(OH)2D3 at a concentration of 20 nM obtained the maximal inhibition (approximately 60%) to the Ca2+ uptake [2].
