- W4387563724 abstract "The NK1 receptor (NK1R) is a molecular target for both approved and experimental drugs intended for a variety of conditions, including i.a. emesis, pain or cancers. While contemplating modifications to the typical NK1R pharmacophore, we wondered whether the CF3 groups common for many NK1R ligands, could be replaced with some other moiety. Our attention was drawn by the SF5-group, and so we designed, synthesized and tested for NK1R affinity ten novel SF5-containing compounds. All the novel analogues exhibit detectable NK1R binding, with the best of them, compound 5a, binding only slightly worse (IC50 = 34.3 nM) than the approved NK1R-targeting drug, aprepitant (IC50 = 27.7 nM). Molecular docking provided structural explanation of SAR. According to our analysis, the SF5 group in our compounds occupies a position similar to that of one of CF3 groups of aprepitant as found in the crystal structure. Additionally, we checked on whether the docking scoring function or energies derived from Fragment Molecular Orbital quantum chemical calculations may be helpful in explaining and predicting the experimental receptor affinities for our analogues. Both these methods produce moderately good results. Overall, this is the first demonstration of the utility of the SF5-group in the design of NK1R ligands." @default.
