Structure–activity relationship studies on ortho-substituted cinnamic acids, a new class of selective EP3 antagonists
摘要:
A series of novel ortho-substituted cinnamic acids have been synthesized, and their binding activity and selectivity on the four prostaglandin E, receptors evaluated. Many of them are very potent and selective EP3 antagonists (K-i 3-10 nM), while compound 9 is a very good and selective EP2 agonist (K-i 8 nM). The biological profile of the EP2 agonist 9 in vivo and the metabolic profile of selected EP3 antagonists are also reported. (C) 2004 Elsevier Ltd. All rights reserved.

Ethylene is one of the most important buildingblocks in industry for the production of polymers and commodity chemicals. 13C‐ and D‐isotope‐labeled ethylenes are also valuable reagents with applications ranging from polymer‐structure determination, reaction‐mechanism elucidation to the preparation of more complex isotopically labeled compounds. However, these isotopic derivatives are expensive, and

Nickel-catalyzed intermolecular benzylation and heterobenzylation of unactivated alkenes to provide functionalized allylbenzene derivatives are described. A wide range of both the benzylchloride and alkene coupling partners are tolerated. In contrast to analogous palladium-catalyzed variants of this process, all reactions described herein employ electronically unbiased aliphatic olefins (including
Compounds and methods for treating prostaglandin mediated diseases, and certain pharmaceutical compositions thereof are disclosed. The compounds are represented by formula II:
Ar1—W—Ar2—X—Q II
The compounds of the invention are structurally different from NSAIDs and opiates, and are antagonists of the pain and inflammatory effects of E-type prostaglandins.

A method for the cross-coupling reactions of aryldiazonium salts with trialkylallylsilanes via merged gold/photoredoxcatalysis is described. The reaction is proposed to proceed through a photoredox-promoted generation of an electrophilic arylgold(III) intermediate that undergoes transmetalation with allyltrimethylsilane to form allylarenes.
