Discovery of a novel indole series of EP1 receptor antagonists by scaffold hopping
摘要:
We describe the medicinal chemistry approach that generated a novel indole series of EP1 receptor antagonists. The SAR of this new template was evaluated and culminated in the identification of compound 12g which demonstrated in vivo efficacy in a preclinical model of inflammatory pain. (C) 2008 Elsevier Ltd.

The dehydrogenativecoupling of indolines with alcohols catalyzed by an iridium complex has been achieved to afford both N- and C3-alkylated indoles selectively, by simply changing the addition time of a base additive. The iridacycle catalyst plays multiple roles in these reactions, which dehydrogenates both amines and alcohols and catalyzes the coupling reactions. Mechanistic studies reveal that a

Provided herein are novel aromatic heterocyclic compounds or a stereoisomer, a geometric isomer, a tautomer, an N-oxide, a hydrate, a solvate, a metabolite, a pharmaceutically acceptable salt or a prodrug thereof, and their uses for treating Alzheimer's disease. Also provided herein are pharmaceutical compositions containing such compounds, and methods for using such compounds or pharmaceutical compositions thereof to treat Alzheimer's disease.
iron carbonyl complexes have been applied in alkylation of indoles with various benzylic alcohols, aliphatic alcohols (butanol, ethanol, methanol and 2‐methylpentanol) via the hydrogen autotransfer strategy in mild reaction conditions. Experimental works highlight the role of the bifunctional iron complexes and the base. These iron complexes demonstrated a broad applicability in mildconditions and
Photocatalysis enables the cascade reactions of indoles and CBr4 in MeOH through a C(sp2)H functionalization/methanolysis sequence. The title reaction provides an efficient access to indole 2‐ and 3‐carboxylates in a single operation (no preinstallation of protecting as well as directing groups was required) with good yields under mild reaction conditions.
The present application relates to compounds of formula (I) or a pharmaceutically acceptable derivative thereof; wherein X, R
