Terbutaline 83-100 beta-3 adrenergic receptor Cavia porcellus 124-142 11885748-6 2001 In the presence of (+/-)-atenolol and (+/-)-butoxamine, however, the non-selective beta1, beta2- and beta3-adrenoceptor antagonist (+/-)-bupranolol caused a concentration-dependent rightward shift of the concentration-response curves for (+/-)-terbutaline and (+/-)-fenoterol. Terbutaline 238-255 beta-3 adrenergic receptor Cavia porcellus 101-119
