Biological Activity

Description RMC-4550 is a potent SHP-2inhibitor with an IC50 of 1.55 nM and it has no significant activity vs. 468 kinases, the catalytic domain of 15 phosphatases and other cellular targets including GPCRs, transporters and ion channels.
Targets
SHP-2 [1]
(Cell-free assay)
1.55 nM
In vitro

RMC-4550 inhibits purified, activated full length human SHP2 with an IC50 of 1.55 nM, and has cellular IC50 of 39 nM in PC9 cells with a pERK readout. RMC-4550 has no detectable inhibitory activity up to 10 µM against the catalytic domain of SHP2, a panel of 14 additional protein phosphatases, and a panel of 468 protein kinases. RMC-4550 exhibits low to moderate cross species in vitro intrinsic clearance (3.6-24 µL/min/million cells) in hepatocytes, a high passive permeability (458 nm/s) and efflux ratio of 1[1].
In vivo

RMC-4550 has moderate to high bioavailability and has a half-life amenable for once daily oral administration. In the EGFR-driven KYSE-520 human esophageal cancer xenograft model, RMC-4550 has a dose dependent efficacy consistent with target modulation, assessed by phospho-ERK inhibition in tumors. RMC-4550 is well tolerated at doses that achieved maximal and sustained efficacy in this model[1].

Protocol (from reference)

Cell Assay:

[2]
  • Cell lines

    HEK-293 cells

  • Concentrations

    --

  • Incubation Time

    1 h

  • Method

    30,000 HEK-293 cells per well are plated in 96-well plates in Biotin-free RPMI supplemented with 0.1% fetal bovine serum, 0.02% bovine serum albumin. Cells are treated with serial 3-fold dilutions of RMC-4550 diluted in biotin-free media supplemented with 0.02% bovine serum albumin (final DMSO concentration equivalent to 0.1%) for one hour. For the final 5 minutes of drug treatment, cells are stimulated with 50 ng/mL EGF, lysed and subjected to ERK1/2 phosphorylation analysis.
Animal Study:

[2]
  • Animal Models

    Female (6-8 week old) athymic nude mice implanted with NCI-H358 (Balb/c strain background) or MIA PaCa-2 (NCR nude strain background) tumor cells subcutaneously in the flank

  • Dosages

    3-60 mg/kg

  • Administration

    PO
