Biological Activity

1α-Hydroxy-3-epi-vitamin D3, a natural metabolite of 1alpha,25-dihydroxyvitamin D3, is a potent suppressor of parathyroid hormone (PTH) secretion[1]. 1 alpha, 25(OH)2D3 is an important negative regulator of parathyroid hormone (PTH) gene transcription[1]. In ROS 17/2.8 cells, 1α-OHD3 (10 μM) not only metabolized into 1αOH-3-epi-D3 and 1α,25(OH)2D3 but also 1α,25(OH)2-3-epi-D3[2].
