A Novel Class of Potent Nonglycosidic and Nonpeptidic Pan-Selectin Inhibitors
摘要:
An early step of the inflammatory response, the rolling of leukocytes on activated endothelial cells, is mediated by selectin/carbohydrate interactions. The tetrasaccharide sialy Lewis(x) is a ligand for E-, P-, and L-selectin and therefore serves as a lead structure for the development of analogues. A combination of synthesis and structure-based design allowed rapid optimization. The current lead 2a was evaluated in our E-selectin cell flow chamber assay where it proved to inhibit rolling and adhesion with an IC50 of 28 +/- 7 mu M. The assays used are predictive for the in vivo efficacy of test compounds as shown for 2a in a proteose peptone induced peritonitis model of acute inflammation in mice.

Es wird eine Klasse nichtglykosidischer und nichtpeptidischer Selektininhibitoren mit niedrigem Molekulargewicht nach der allgemeinen Formel (1) beschrieben, sowie Verfahren zu ihrer Herstellung. Es handelt sich dabei um eine Klasse untoxischer, in vivo anti-inflammatorisch wirksamer Selektininhibitoren, welche nicht die Nachteile der glykosidischen Inhibitorkomplexe aufweist und zudem in vitro potenter ist, als der bekannte Wirkstoff Bimosiamose. Es werden weiterhin die Verbindungen enthaltende Arzneimittel und deren Verwendung bei der Behandlung von Erkrankungen beschrieben.
