IC50: NSC-87877 potently inhibited Shp2 with an IC50 of 0.318 ± 0.049 μM. NSC-87877 seemed to have no selectivity between human Shp2 and Shp1 (IC50 0.355 ± 0.073μM). In addition, NSC-87877 showed approximately 5-, 24-, 206-, 266-, and 475-fold selectivity for Shp2 over PTP1B (IC50 1.691 ± 0.407μM), HePTP (IC50 7.745 ± 1.561μM), DEP1 (IC50 65.617± 4.120μM), CD45 (IC50 84.473 ± 16.185μM), and LAR (IC50 150.930 ± 9.077μM), respectively [1].
Shp2, a nonreceptor protein tyrosine phosphatase (PTP) encoded by the PTPN11 gene, is involved in the growth factorinduced activation of mitogen-activated protein kinases Erk1 and Erk2. Moreover, gain-of-function Shp2 mutations have been found in Noonan syndrome and childhood leukemias. Therefore, Shp2 PTP inhibitors are required for the evaluation of Shp2 as a therapeutic target. NSC87877, a novel SHP-2 inhibitor, has been observed dose-dependent cytotoxicity in leukemic cell lines.
In vitro: Molecular modeling and site-directed mutagenesis studies suggested that NSC-87877 binds to the catalytic cleft of Shp2 PTP. It is noteworthy that NSC-87877 inhibited epidermal growth factor (EGF)-induced activation of Shp2 PTP, Ras, and Erk1/2 in cell cultures but did not block EGF-induced Gab1 tyrosine phosphorylation or Gab1-Shp2 association. Furthermore, NSC-87877 inhibited Erk1/2 activation by a Gab1-Shp2 chimera but did not affect the Shp2-independent Erk1/2 activation by phorbol 12-myristate 13-acetate. These results identified NSC-87877 as the first PTP inhibitor capable of inhibiting Shp2 PTP in cell cultures without a detectable off-target effect [1].
In vivo: An mice in-vivo study aimed to investigate the effects of S NSC-87877 on inflammatory pain and its underlying mechanisms. In this study, immediately after behavioral tests, sinistral spinal dorsal horn was collected for immunoblotting analysis of the expression of NMDA receptors. Results showed that NSC-87877 alleviated CFA-induced mechanical allodynia, which had no effects on the nociceptive responses in naive mice. Moreover, NSC-87877 specifically abolished the increase in the synaptic expression of NMDA receptor NR2B subunits in inflamed mice. These findings indicated that NSC-87877 could ameliorate inflammatory pain by inhibiting the synaptic accumulation of NR2B in spinal dorsal horn [2].
Clinical trial: NSC-87877 is currently in the preclinical development and no clinical trial is ongoing.
