CMX inhibits the activity of mammalian DHFR. (a) Molecular docking simulations predict an interaction between CMX and the catalytic domain of yeast Dfr1 (∆G = − 6.82 kcal/mol). (b) The residues implicated in the predicted interaction from panel (a). (c) CMX is also predicted to interact with the catalytic domain of mammalian DHFR (∆G = − 7.17 kcal/mol). (d) the residues implicated in the predicted interaction from panel (c). (e) CMX is predicted to interact with the catalytic domain of the P. infestans DHFR protein ((∆G = − 7.51 kcal/mol). (f) The residues implicated in the predicted interaction from panel (e). (g) A DHFR assay between increasing concentrations of CMX and mammalian DHFR. The presence and absence of MTX were used as experimental controls.
