BN/CC isosterism in borazaronaphthalenes towards phosphodiesterase 10A (PDE10A) inhibitors

Abstract

The application of BN/CC isosterism is explored as a method of expanding the scope of core scaffolds in biologically active compounds. The viability of potential drug candidates incorporating BN-heteroaromatic moieties was investigated through the synthesis of BN-substituted analogs to known phosphodiesterase (PDE10A) inhibitors, namely MP10 and a selection of N-methylanilide analogs. These in some cases revealed unexpectedly potent and relatively stable derivatives, providing further support for the potential of BN-incorporation in medicinal chemistry.

Keywords: Antipsychotics; Borazaronaphthalenes; PDE10A inhibitors.
