Structure-activity relationship studies of the cyclopentapeptide CXCR4 antagonists (cyclo(-l-/d-Arg1-Arg2-2-Nal 3-Gly4-d-Tyr5-)) suggest that the l-/d-Arg 1-Arg2-2-Nal3/sup

Artificial ditopic receptors for the differentiation of phosphorylated peptides varying in i + 3 amino acid side chains were synthesized, and their binding affinities and selectivities were determined. The synthetic receptors show the highest binding affi

(Chemical Equation Presented) To introduce chirality and functional groups adjacent to guanidiniums to modulate specificity and affinity in recognition, N,N′-bis(Boc)-α-guanidino acids were synthesized from α-amino acid methyl esters. Protected α-guanidino acids coupled to cyclohexylamine and trans-1,4-diaminocyclohexane in good yield and with retention of stereochemistry. Boc deprotection was conducted under mild acidic conditions (0.5 M HCl/EtOAc) to minimize epimerization. The deprotected guanidinium is configurationally stable under more acidic conditions. This approach represents a practical, convergent, stereospecific methodology to introduce chiral α-substituted guanidinium groups into molecules.

As a new scaffold for peptidomimetic synthesis, a highly constrained bifunctional diketopiperazine, 4, has been prepared by smooth N-alkylation with tert-butyl bromoacetate. As a first application, we describe herein the synthesis of new peptidomimetics of the Arg-Gly-Asp (RGD) sequence. The product 30, which shows a selective platelet-aggregation inhibiting activity, can be used as a lead for the preparation of more potent products.
