IMPROVED LINKERS FOR ANCHORING TARGETING LIGANDS

An improved linker which lacks chiral centers between a hydrophobic anchor for coupling to lipid-based particles and a targeting agent has suitable hydrophobic/hydrophilic properties for use in vivo.

Isoxazolines as potent antagonists of the integrin α(v)β3

Starting with lead compound 2, we sought to increase the selectivity for α(v)β3-mediated cell adhesion by examining the effects of structural changes in both the guanidine mimetic and the substituent α to the carboxylate. To prepare some of the desired aminoimidazoles, a novel reductive amination utilizing a trityl-protected aminoimidazole was developed. It was found that guanidine mimetics with a wide range of pK(a)'s were potent antagonists of α(v)β3. In general, it appeared that an acylated 2-aminoimidazole guanidine mimetic imparted excellent selectivity for α(v)β3-mediated adhesion versus α(IIb)β3-mediated platelet aggregation, with selectivity of approximately 3 orders of magnitude observed for compounds 3g and 3h. It was also found in this series that the α- substituent was required for potent activity and that 2,6-disubstituted arylsulfonamides were optimal. In addition, the selective α(v)β3 antagonist 3h was found to be a potent inhibitor of α(v)β3-mediated cell migration.
