Design, synthesis, and biological evaluation of novel potent and selective alphavbeta3/alphavbeta5 integrin dual inhibitors with improved bioavailability. Selection of the molecular core.

A novel series of potent and selective alpha(v)beta(3)/alpha(v)beta(5) dual( )()inhibitors was designed, synthesized, and evaluated against several integrins. These compounds were synthesized through a Mitsunobu reaction between the guanidinium mimetics and the corresponding central templates. Guanidinium mimetics with enhaced rigidity (i.
