Trimetoquinol (1, TMQ) is a potent nonselective beta-adrenergic receptor (AR) agonist and a thromboxane A(2)/prostaglandin endoperoxide (TP) receptor antagonist, while 3',5'-diiodo-TMQ (2) exhibits beta(3)-AR selectivity. In search of selective beta(3)-AR agonists as potential drugs for the treatment of human obesity and type II diabetes mellitus, a series of 1-(3, 5-diiodo-4-methoxybenzyl)-1,2,3,4-tetrahydroisoquinolin-6-ols has been prepared and evaluated for their biological activities at human beta(1)-, beta(2)-, and beta(3)-ARs expressed in Chinese hamster ovary (CHO) cells. The compounds have been synthesized by the Bischler-Napieralski cyclization of corresponding amides followed by NaBH(4) reduction, and the halogens in the aromatic ring A were introduced by direct halogenation of protected compound 11. Whereas halogen substitution in ring A reduced either potency or intrinsic activity on beta(3)-AR, the non-halogen-substituted compounds 8 and 10 were potent, selective, nearly full agonists for beta(3)-AR.
