Abstract : A quaternary ammonium betaine <b>7</b> is described which shows exceptional potency and selectivity (1.4 to >3 logs) for the α<sub>v</sub>β<sub>6</sub> integrin receptor over the other α<sub>v</sub> integrins as determined in cell adhesion assays. <b>7</b> is prepared by remarkably stereoselective methylation, the origins of which are discussed. The chemical, biological, physicochemical, and pharmacokinetic properties of <b>7</b> and its docking into α<sub>v</sub>β<sub>6</sub> are described along with related analogues.
