Substituted 4-Phenyl-2-(phenylcarboxamido)-1,3-thiazole Derivatives as Antagonists for the Adenosine A1 Receptor
摘要:
The synthesis and receptor binding of novel adenosine receptor antagonists is described. We found that non-xanthine 4-phenyl-2-(phenylcarboxamido)-1,3-thiazole derivatives may have high affinity and substantial selectivity for the adenosine A(1) receptor. (C) 2001 Elsevier Science Ltd.

on a template approach. Structure-affinityrelationships revealed insights for extended knowledge of the receptor-ligand interaction. We replaced the bicyclic heterocyclic ring system of earlier described isoquinoline and quinazoline adenosine A(3) receptor ligands by several monocyclic rings and investigated the influence thereof on adenosine receptor affinity. The thiazole or thiadiazole derivatives

The NF-E2-related factor 2 (Nrf2) is a key transcriptional regulator of antioxidant defense and detoxification. To directly monitor stabilization of Nrf2 we fused its Neh2 domain, responsible for the interaction with its nucleocytoplasmic regulator, Keap1, to firefly luciferase (Neh2-luciferase). It is shown herein that Neh2 domain is sufficient for recognition, ubiquitination and proteasomal degradation of Neh2-luciferase fusion protein. The novel Neh2-luc reporter system allows direct monitoring of the adaptive response to redox stress and classification of drugs based on the time-course of reporter activation. The novel reporter was used to screen a library of compounds to identify activators of Nrf2. The most robust and yet non toxic Nrf2 activators found—nordihydroguaiaretic acid, fisetin, and gedunin-induced astrocyte-dependent neuroprotection from oxidative stress via an Nrf2-dependent mechanism.
