WB-4101 is a compound which acts as anantagonist at theα_1B-adrenergic receptor. It was one of the first selective antagonists developed for this receptor and was invented in 1969, but is still commonly used in research into adrenergic receptors, especially as alead compound from which to develop more selective drugs.^[1]^[2]^[3]^[4]^[5]^[6]
