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.
