Thiophenesulfonamides as endothelin receptor antagonists
摘要:
The synthesis and in vitro binding affinities of a series of thiophenesulfonamides as ET(A) selective endothelin receptor antagonists is described. The most potent inhibitor displayed an IC50 of 43 nM and 3 mu M to ET(A) and ET(B) receptors, respectively. Copyright (C) 1996 Elsevier Science Ltd

and/or tertiary alcohols and unsymmetrical ketones have been obtained in moderate to good yields by the palladium-catalyzed (5 mol%) carbonylative coupling of aryl iodides with alkylaluminum compounds under very mild conditions (20–50°C, 1 atm of carbon monoxide). The type of the reaction product depended on the aluminum reagent employed. While the selective formation of secondary alcohols was observed
The present invention provides a compound of Formula (I)
or a pharmaceutically acceptable salt thereof wherein R1, R2, R3, A1, A2, A3, A4, L, B1, B2, B3 and B4 are as defined herein. The compounds of Formula I have been found to act as glucagon antagonists or inverse agonists. Consequently, the compounds of Formula I and the pharmaceutical compositions thereof are useful for the treatment of diseases, disorders, or conditions mediated by glucagon.
