Scalable synthesis of an integrin-binding peptide mimetic for biomedical applications
摘要:
A scalable, solution-phase synthesis of the selectively protected non-peptide RGD (arginine-glycine-aspartic acid) mimetic 6 is described. This synthesis serves as an alternative to the previously described solid-phase synthesis of this compound, thereby making this important integrin-binding mimetic readily accessible. The free carboxylic acid of 6 was conjugated to a protected diamine, followed by global deprotection to give a derivative 27, suitable for immobilization onto amine-reactive surfaces. The RGD mimetic 28 demonstrated superior biological activity in comparison to a native linear RGD peptide and the semi-synthetic cyclic cRGDfK peptide in a cell attachment inhibition assay.

intracellular cysteine proteases with several important physiological functions. Calpain inhibitors may be promising tools in the analysis of the function of the enzyme in diseases caused by overexpression/activation. Here, we report on the synthesis, solution conformation, and characterization of novel group of azapeptides whose sequences originate from an efficient m‐calpain substrate, TPLKSPPPSPR, described

The present invention relates to a method for site-selective coupling of a first agent to a second agent, comprising the steps of: contacting a first agent comprising at least one furan moiety with an activation signal and with a second agent comprising at least one hydrazine moiety or at least one hydroxylamine moiety, thereby activating said furan moiety to an activated furan moiety; and reacting said activated furan moiety with the hydrazine moiety or the hydroxylamine moiety, thereby site-selectively coupling said first agent to said second agent.
