Chirality of vitamin-D derivatives affects the protonation states of its receptor protein

31 Oct 2018

Ab initio molecular orbital calculations have elucidated that a change in the protonation states of the vitamin-D receptor is induced by altered chirality of vitamin-D derivatives

Researchers at Toyohashi University of Technology, in cooperation with researchers at Teijin Pharma Ltd. and Teikyo University, have highlighted the possibility that chirality of vitamin-D derivatives can affect the protonation states of histidine residues in the vitamin-D receptor protein via ab initio molecular simulations and biomedical analyses. This finding emphasizes that protonation states should be considered more precisely in molecular simulations, when investigating specific interactions between candidate medicines and target proteins related to disease pathogenesis.
