Metabolism of selective 20-epi-vitamin D3 analogs in rat osteosarcoma UMR-106 cells: Isolation and identification of four novel C-1 fatty acid esters of 1α,25-dihydroxy-16-ene-20-epi-vitamin D3.[Pubmed: 28089927]


Analogs of 1α,25-dihydroxyvitamin D3 (S1) with 20-epi modification (20-epi analogs) possess unique biological properties. We previously reported that 1α,25-dihydroxy-20-epi-vitamin D3 (S2), the basic 20-epi analog is metabolized into less polar metabolites (LPMs) in rat osteosarcoma cells (UMR-106) but not in a perfused rat kidney. Furthermore, we also noted that only selective 20-epi analogs are metabolized into LPMs. For example, 1α,25-dihydroxy-16-ene-20-epi-vitamin D3 (S4), but not 1α,25-dihydroxy-16-ene-23-yne-20-epi-vitamin D3 (S5) is metabolized into LPMs. In spite of these novel findings, the unequivocal identification of LPMs has not been achieved to date. We report here on a thorough investigation of the metabolism of S4 in UMR-106 cells and isolated two major LPMs produced directly from the substrate S4 itself and two minor LPMs produced from 3-epi-S4, a metabolite of S4 produced through C-3 epimerization pathway. Using GC/MS, ESI-MS and 1H NMR analysis, we identified all the four LPMs of S4 as 25-hydroxy-16-ene-20-epi-vitamin D3-1-stearate and 25-hydroxy-16-ene-20-epi-vitamin D3-1-oleate and their respective C-3 epimers. We report here for the first time the elucidation of a novel pathway of metabolism in UMR-106 cells in which both 1α,25(OH)2-16-ene-20-epi-D3 and 1α,25(OH)2-16-ene-20-epi-3-epi-D3 undergo C-1 esterification into stearic and oleic acid esters.



Synthesis of 2α- and 2β-(3-hydroxypropyl)- 7,8-cis-14-epi-1α,25-dihydroxy-19-norvitamin D3 and their biological activity.[Pubmed: 27629592]


According to the binding mode of 14-epi-1α,25-dihydroxy-19-nortachysterol in the ligand binding domain of human vitamin D receptor (hVDR), i.e., 5,6- and 7,8-s-trans configuration that was shown by X-ray co-crystallographic analysis, 7,8-cis-locked 1α,25(OH)2D3 analogs were synthesized. In this paper, the synthesis and biological activity of 2α- and 2β-(3-hydroxypropyl)-7,8-cis-14-epi-1α,25-dihydroxy-19-norvitamin D3 are reported. The A-ring and CD-ring precursors for the Julia-Kociensky coupling reaction to create a diene system of the target molecules were prepared using our original methods. hVDR binding affinity and osteocalcin promoter transactivation activity of the new 7,8-cis-14-epi-vitamin D3 analogs were evaluated. Interestingly, the 2β-substituted 7,8-cis-analog was a better binder for hVDR than the 2α-isomeric counterpart.



A new suprasterol by photochemical reaction of 1α,25-dihydroxy-9-methylene-19-norvitamin D3.[Pubmed: 26693597]


The UV-induced photochemical reaction of 1α,25-dihydroxy-9-methylene-19-norvitamin D3 has been investigated. The pentacyclic structure of the isolated product has been unequivocally established by X-ray crystallographic analysis. The possible reaction paths of the examined photochemical transformation are discussed. Biological in vivo and in vitro tests proved that the photoproduct is devoid of calcemic activity.



Synthesis, metabolism, and biological activity of 2-[3-(tetrazolyl)propyl]-1α,25-dihydroxy-19-norvitamin D3.[Pubmed: 26232635]


Recently, we found that 2α-[2-(tetrazol-2-yl)ethyl]-1α,25-dihydroxyvitamin D3 showed higher osteocalcin promoter transactivation activity in human osteosarcoma (HOS) cells and a greater therapeutic effect in ovariectomized (OVX) rats in vivo than those of active vitamin D3, 1α,25(OH)2D3. We were interested in introducing a heterocyclic ring to the C2 position of the seco-steroidal structure via an alkyl linker, and four novel C2-(3-tetrazolylpropyl) substituted 1α,25-dihydroxy-19-norvitamin D3 analogs, 2α-[3-(tetrazol-1-yl)propyl]-, 2β-[3-(tetrazol-1-yl)propyl]-, 2α-[3-(tetrazol-2-yl)propyl]-, and 2β-[3-(tetrazol-2-yl)propyl]-19-nor-1α,25(OH)2D3 were synthesized. Among them, 2α-[3-(tetrazol-1-yl)propyl]-19-nor-1α,25(OH)2D3 showed weak binding affinity for human vitamin D receptor (hVDR) (2.6% of 1α,25(OH)2D3 and ca. 15% of 19-nor-1α,25(OH)2D3) and weak VDR transactivation activity in HOS cells (EC50 7.3nM, when 1α,25(OH)2D30.23nM). Although the other three compounds could not act as VDR binders by evaluation of the competition assays, 2α-[3-(tetrazol-2-yl)propyl]-19-nor-1α,25(OH)2D3 showed weak transactivation activity (EC50 12.5nM). Metabolic stability of the 2α-substituted compounds 2α-[3-(tetrazol-1-yl)propyl]- and 2α-[3-(tetrazol-2-yl)propyl]-19-nor-1α,25(OH)2D3 was higher than that of the 2β-substituted counterparts 2β-[3-(tetrazol-1-yl)propyl]- and 2β-[3-(tetrazol-2-yl)propyl]-19-nor-1α,25(OH)2D3 against human CYP24A1. Introduction of a tetrazole ring to the C2-position of the 19-norvitamin D3 skeleton with the propyl linker led to weak VDR agonistic activity with stability against CYP24A1 metabolism.
