SHP099 hydrochloride 是一种有效的、选择性的、口服生物可利用的、有效的 SHP2 抑制剂。
产品描述
SHP099 is a potent, selective, orally bioavailable, and efficacious SHP2 inhibitor.
体外活性
The X-ray co-crystal for SHP099 with SHP2 reveals a new interaction with the basic amine and the Phe113 backbone carbonyl. SHP099 exhibits inhibition of cell proliferation (KYSE-520 model) with an IC50 of 1.4 μM. SHP099 also exhibits high solubility and high permeability with no apparent efflux in Caco-2 cells[1]. SHP099 concurrently binds to the interface of the N-terminal SH2, C-terminal SH2, and protein tyrosine phosphatase domains, therefore, inhibiting SHP2 activity through an allosteric mechanism. SHP099 suppresses RAS–ERK signaling to inhibit the proliferation of receptor-tyrosine-kinase-driven human cancer cells[2].
体内活性
Dose-dependent exposure and modulation of the pharmacodynamic marker p-ERK was observed in xenografts following single doses of 30 and 100 mg/kg (red and blue lines, respectively). A daily oral dose of 10 or 30 mg/kg yield 19% and 61% tumor growth inhibition, respectively. Tumor stasis is achieved at 100 mg/kg[1].
激酶实验
The inhibition of SHP2 from the tested compounds (SHP099) concentrations varying from 0.003-100 μM is monitored using an assay in which 0.5 nM of SHP2 is incubated with of 0.5 μM of peptide IRS1_pY1172(dPEG8)pY1222. After 30-60 minutes incubation at the surrogate substrate, DiFMUP is added to the reaction and incubated at 25 °C for 30 minutes. The reaction is then quenched by the addition of 5 μL of a 160 μM solution of bpV(Phen). The fluorescence signal is monitored using a microplate reader using excitation and emission wavelengths of 340 nm and 450 nm, respectively[1].
细胞实验
Cells are plated onto 96-well plates in 100 μL medium. SHP099 with various concentrations (1.25, 2.5, 5, 10, 20 μM) are added 24 h after cell plating. At day 5, 50 μL Celltiter-Glo reagent is added, and the luminescent signal is determined[1].
