Abstract
A novel series of potent and specific alpha(v) integrin antagonists has been obtained by aminoalkyl substitutions on benzocyloheptene acetic acids as a rigid GD bioisostere. The preferred compounds 1-2, 1-3 and 1-8, showed nano- to subnanomolar IC(50) values on alpha(v)beta(3) and alpha(v)beta(5) integrins, with favorable pharmacokinetics.
