Fig. 6

A The quaternary ammonium silane attaches at specific pockets on MMPs producing a “Clouting motion effect” preventing the attachment of other ligands. B The arrows indicate attachment of K21 chain on various clefts on MMP surfaces. The QAS molecule depicts a smacking by this attachment all over the MMP active sites preventing other molecules to ascribe on MMP structure. D 3D interactions depicting Clouting Motion Effect of K21 with MMPs
