A new series of 1,2-naphthoquinone derivatives was synthesized by various synthetic methods and evaluated for their ability to inhibit protein tyrosine phosphatase 1B (PTP1B). 1,2-Naphthoquinone derivatives with substituent at R(4) position showed submicromolar inhibitory activity, and compound 24 demonstrated 10- to 60-fold selectivity against the tested phosphatases. Also, several 4-aryl-1,2-naphthoquinone derivatives with substituents at R(3), R(6), R(7), or/and R(8) showed submicromolar inhibitory activity and good plasma stability.

The oxidation of 1,4-benzoquinone, 2-phenyl-1,4-benzoquinone, 1,4-naphthoquinone, and 1,2-naphthoquinone by palladium(II) acetate in acetic acid containing arenes gave the corresponding aryl-sustituted quinones.Treatment of 1,4-naphthoquinone with aromatic heterocycles such as furfural, 2-acetylfuran, methyl 2-furoate, 2-acetylthiophene, 1-(phenylsulfonyl)pyrrole, 1-(phenylsulfonyl)indole, 4-pyrone, and 1-methyl-2-pyridone in the presence of palladium acetate gave the corresponding 2-heteroaryl-substituted 1,4-naphthoquinones.
