Discovery and SAR study of hydroxyacetophenone derivatives as potent, non-steroidal farnesoid X receptor (FXR) antagonists
摘要:
Compound 1 (IC50 = 35.2 +/- 7.2 mu M), a moderate FXR antagonist was discovered via high-throughput screening. Structure-activity relationship studies indicated that the shape and the lipophilicity of the substituents of the aromatic ring affect the activity dramatically, increasing the shape and the lipophilicity of the substituents of the aromatic ring enhances the potency of FXR antagonists. Especially, when the OH at C2 position of the aromatic ring was replaced by the OBn substituent (analog 2b), its activity could be improved to IC50 = 1.1 +/- 0.1 mu M. Besides, the length of the linker and the tetrazole structure are essential for retaining the activity. (C) 2014 Elsevier Ltd. All rights reserved.

A series of omegadibenzylaminoalkylamines and related compounds have been prepared and tested as inhibitors of fibrin cross-linking. This structural type was chosen in an attempt to develop noncompetitive inhibitors of fibrinoligase. By the combination of the dibenzylamino moiety at one end and the primary amino group at the other end of a polymethylene chain, the same compound could function both

The first examples of (3 + 2) annulations between azaoxyallyl cations and cyanamides and nitriles to give the corresponding 2-aminoimidazolones and imidazolones are reported. On the basis of the isolation of unexpected imidate products with certain substrates, it is proposed that the reaction proceeds via fast kinetic O-alkylation followed by rearrangement to the thermodynamically favored 2-aminoimidazolones

A new Fe- or Co-catalyzed Cl/Zn-exchange reaction allows the direct transformation of aryl, heteroaryl, and also alkyl chlorides into the corresponding zinc reagents. The method tolerates functional groups such as a nitrile or an ester. Remarkably, secondary and tertiary alkyl chlorides are suitable substrates for the Cl/Zn exchange.

The imidazole compounds of the general formula (I): ##STR1## wherein Y is a carboxyl group, a hydroxymethyl group, an N-di or -mono alkyl substituted or unsubstituted carbamoyl group, a cyano group, or an N-di or -mono alkyl substituted or unsubstituted aminomethyl group, and n is an integer of 3 to 20; and pharmaceutically acceptable salts thereof. These compounds have a strong inhibitory effect on thromboxane synthetase from rabbit platelet microsomes, and are useful as therapeutically active agents for inflammation, hypertension, thrombus, cerebral apoplexy and asthma.
