NT157 (Tyrphostin NT157) is a selective IRS-1/2 inhibitor that induces Ser-phosphorylation and consequently the degradation of IRS-1/2. NT157 (Tyrphostin NT157) is a first-in-class anti-cancer agent that also targets Stat3 signaling pathway[1][2].
NT157 (0.3-3 μM; 72 hours) shows a strong dose-dependent inhibition of growth in all cell lines tested, and the IC50 s ranges from 0.3 to 0.8 μM[1].
NT157 (1-3 μM; 24 hours) induces cell cycle arrest in MG-63 and U-2OS OS cells[1].
NT157 (1-3 μM; 48 hours) downregulates the Tyr-phosphorylation of IRS-1 in the MG-63 and U-2OS cells[1].
NT157 (50 mg/kg; i.p.; three times per week for 6 weeks) significantly delayed tumor growth in castrated mice bearing LNCaP xenografts [3].
