Figure 4.
Figure 4. Stereo representation of compound-1 bound to the ATP-binding site of MK2. Inhibitor and interacting residues shown in stick representation and atom colors (inhibitor carbon atoms in green). In (a) crystal form-1, in (b) molecule-A of crystal form-2. Black dotted lines represent hydrogen bonds. Thick orange dotted lines indicate π–π stacking between compound-1 and Asp142, and two weak hydrogen bonds (C-H···O to Glu139 in (a) and (b) and N-H···π to Asp207 in (b)).
