Discovery of substituted benzyl tetrazoles as histamine H3 receptor antagonists
摘要:
A series of potent and subtype selective H3 receptor antagonists containing a novel tetrazole core and diamine motif is reported. A one-pot multi-component Ugi reaction was utilised to rapidly develop the structure-activity relationships (SAR) of these compounds. Optimisation for liver microsome stability (t(1/2) >60 min), minimal CYP inhibition (IC(50) >50 mu M) and high cell permeability (Caco-2 P(app) >20 x 10 (6) cm/s) identified several compounds with drug-like properties.
