BioAssay: AID 612701

Agonist activity at human VDR in human MG63 cells assessed as stimulation of osteocalcin production by enzyme immunoassay relative to 1,25(OH)2D3

Novel vitamin D(3) analogs with carboxylic acid were explored, focusing on a nonsecosteroidal analog, LG190178, with a bisphenyl skeleton. From X-ray analysis of these analogs with vitamin D receptor (VDR), the carboxyl groups had very unique hydrogen bonding interactions in VDR and mimicked 1alpha-hydroxy group and/or 3beta-hydroxy group of 1alpha,25-dihydroxyvitamin D(3). A highly potent more ..

Title: Novel nonsecosteroidal vitamin D3 carboxylic acid analogs for osteoporosis, and SAR analysis.

Abstract: Novel vitamin D(3) analogs with carboxylic acid were explored, focusing on a nonsecosteroidal analog, LG190178, with a bisphenyl skeleton. From X-ray analysis of these analogs with vitamin D receptor (VDR), the carboxyl groups had very unique hydrogen bonding interactions in VDR and mimicked 1alpha-hydroxy group and/or 3beta-hydroxy group of 1alpha,25-dihydroxyvitamin D(3). A highly potent analog, 6a, with good in vitro activity and pharmacokinetic profiles was identified from an SAR study. Compound 6a showed significant prevention of bone loss in a rat osteoporosis model by oral administration.
