Selenoglycosides in silico: ab initio-derived reparameterization of MM4, conformational analysis using histo-blood group ABH antigens and lectin docking as indication for potential of bioactivity. |
Abstract | ||
---|---|---|
The identification of glycan epitopes such as the histo-blood group ABH determinants as docking sites for bacterial/viral
infections and signals in growth regulation fuels the interest to develop non-hydrolysable mimetics for therapeutic applications.
Inevitably, the required substitution of the linkage oxygen atom will alter the derivative’s topology. Our study addresses
the question of the impact of substitution of oxygen by selenium. In order to characterize spatial parameters and flexibility
of selenoglycosides, we first performed ab initio calculations on model compounds to refine the MM4 force field. The following
application of the resulting MM4R version appears to reduce the difference to ab initio data when compared to using the MM4
estimator. Systematic conformational searches on the derivatives of histo-blood group ABH antigens revealed increased flexibility
with acquisition of additional low-energy conformer(s), akin to the behavior of S-glycosides. Docking analysis using the Glide
program for eight test cases indicated potential for bioactivity, giving further experimental investigation a clear direction
to testing Se-glycosides as lectin ligands. |
