Validating the 1,2-Difluoro Motif As a Hybrid Bioisostere of CF3 and Et Using Matrix Metalloproteinases As Structural Probes
摘要:
Matrix metalloproteinases (MMPs) are involved in a spectrum of physiological processes, rendering them attractive targets for small-molecule drug discovery. Strategies to achieve selective inhibition continue to be intensively pursued, facilitated by advances in structural biology. Herein, we harness MMPs 2, 8, 9, and 13 to validate the vicinal difluoro motif as a hybrid bioisostere of CF3 and Et (BITE) in a series of modified barbiturate inhibitors. Crystallographic analyses of representative structures reveal conformations of the vicinal difluoro motif that manifest stabilizing hyperconjugative interactions consistent with the stereoelectronic gauche effect. Detailed docking studies of a potent difluorinated probe with MMP-9 are also disclosed and indicate that the structural basis of inhibition is a consequence of the anisotropic nature of the motif. Significant selectivity of MMP 13 versus MMP-2 can be achieved by subtle chain contraction in a BITE-modified inhibitor.

Effect of the fluorination degree of partially fluorinated octyl-phosphocholine surfactants on their interfacial properties and interactions with purple membrane as a membrane protein model
Interfacial properties and membrane protein solubilization activity of a series of partially fluorinated octyl-phosphocholine (PC) surfactants were investigated from the viewpoint of the fluorination degree of the hydrophobic chain. The criticalmicelleconcentration (CMC), surfacetension lowering activity, molecular occupied area at the CMC and free energy changes of micellization as well as adsorption
