4-HYDROXY-3,3-DIMETHYL-2H-BENZO[G]INDOLE-2,5(3H)-DIONE

Описание

BVT 948 is a noncompetitive, cell-permeable inhibitor of protein tyrosine phosphatases (PTP; IC₅₀s = 0.09-1.7 μM). It facilitates the oxidation of the catalytic cysteine residue by hydrogen peroxide. Similarly, it inhibits redox-sensitive cytochrome P450 (CYP) isoforms, including CYP2C19 and CYP2D6, with IC₅₀ values less than 10 μM. BVT 948 also inhibits the protein methyltransferases SETD8, SETD2, G9a, SMYD2, CARM1, and PRMT3 with IC₅₀ values from 0.7 to 3.2 μm. Presumably through its effects on PTPs, BVT 948 enhances insulin signaling in cells and insulin tolerance in ob/ob mice, suppresses the expression of matrix metalloproteinase-9 and invasion in breast cancer cells, and increases NMDA-induced substance P release by spinal cord slices.

Использование

BVT-948 is a noncompetitive cell-permeable inhibitor of tyrosine phosphatases. Helps in the oxidation of the catalytic cysteine residue. May be used as an anti-cancer treatment.

Биологическая активность

Non-competitive, cell-permeable inhibitor of protein tyrosine phosphatases (PTPs) (IC 50 = 0.09-1.7 μ M); displays irreversible inhibition through catalysis of the hydrogen peroxide-dependent oxidation of PTP. Enhances insulin signaling in vitro and insulin tolerance in ob/ob mice in vivo . Also inhibits several cytochrome P450 isoforms (IC 50 < 10 μ M).
