Abstract:
Two benzazaborinine analogues of propranolol were synthesized and extensively profiled in vitro and in vivo. These analogues showed potency and physicochemical and in vitro ADME-tox profiles comparable to propranolol. In addition, both benzazaborinine analogues showed excellent bioavailability and brain penetration following subcutaneous administration in a pharmacokinetic study in rats. These studies unveil the potential of aromatic azaborinines as bioisosteric replacements of naphthalene in drug discovery programs.

Nomenclature of Aromatic Compounds with Multiple Substituents
For disubstituted benzene derivatives, with two groups attached to the benzene ring, three constitutional isomers are possible. For example, consider dimethyl benzene, often called xylene, where the second methyl group can be substituted at the second, third, or fourth carbon. The relative position of the substituents is represented by prefixes ortho, meta, or...
