Abstract
Replacement of the 4-methyl group in a series of N-(3, 4-dimethylisoxa zolyl)benzenesulfonamide endothelin antagonists with a bromine or chlo rine atom resulted in a three- to ten-fold increase in the binding aff inity for both the ET(A) and ET(B) receptors. This potentiation in act ivities was also observed for naphthalene and biphenylsulfonamide endo thelin antagonists. Copyright (C) 1996 Elsevier Science Ltd.
