Synthesis and biological characterization of AQPazide, a novel biotinylated photoaffinity probe for the study of the human platelet throm☐ane A2 receptor
摘要:
SQBAzide, a biotinylated, azido derivative of the TXA(2) receptor antagonist, SQ31,491, was synthesized and characterized. The compound specifically inhibited human platelet aggregation mediated by TXA(2) receptor activation and irreversibly labeled platelet TXA(2) receptors upon exposure to ultraviolet light. This probe should prove to be of significant value for the study of the receptor-ligand binding domain. (C) 1999 Elsevier Science Ltd. All rights reserved.

iodinatable antagonists of the neuropeptidic hormone vasopressin was designed and synthesized by a combination of PyBOP-mediated Boc/solid-phase peptide synthesis and solution synthesis approaches. These were based on modifications of a previously reported potent and selective antagonist of the vasopressor response (V1a receptor) to [arginine]vasopressin, phenylacetyl-D-Tyr(Me)-Phe-Gln-Asn-Arg-Pro-Arg-Tyr-NH2

Acid-catalysed decomposition of (4′-azidophenyl)propanoic and butyric acids leads to ipso-attack by the carboxy group para to the nitrenium ion and the formation of imines of cyclohexadienone spiro-lactones, which can rearrange to the benz-fused lactones; 4′-azido-2-carboxydiphenyl ether behaves the same way to give spiro-lactone (9).

The invention relates to a device suitable for the investigation of ligand-receptor interactions, in particular for the investigation of an analyte target interaction such as biological and chemical molecules and organic components and their interaction with surfaces, consisting of an attenuated total internal reflection element, transparent in the infra-red and of which at least one surface is chemically activated and covalently grafted with an organic molecule able to immobilize the receptor.
The invention further relates to the use of said device and a method for the construction of said device comprising the steps of:
- surface activation of at least one surface of an attenuated total internal reflection element,
- surface grafting with an organic molecule of the activated surface obtained in the previous step, and
- coupling a receptor via covalent fixation on the organic molecule.
