Biological Activity

Description

Pemigatinib is an orally active and selective inhibitor of FGFR with IC50 of 0.4 nM, 0.5 nM, 1.2 nM and 30 nM for FGFR1, FGFR2, FGFR3 and FGFR4, respectively. Pemigatinib has the potential for cholangiocarcinoma.

Targets

FGFR1 ^[1] (Cell-free assay)	FGFR2 ^[1] (Cell-free assay)	FGFR3 ^[1] (Cell-free assay)	FGFR4 ^[1] (Cell-free assay)
0.4 nM	0.5 nM	1.2 nM	30 nM

In vitro

Pemigatinib successfully diminishes the capacity of reactive astrocytes to recruit myeloid cells. Potentially FGFR modulation by pemigatinib may be promising for suppression of proinflammatory astrocyte responses while, at the same time, promoting protective mechanisms in murine and human systems.^[2]

In vivo

No effect of pemigatinib on the disease course is evident on acute EAE.^[2]

Protocol (from reference)

Cell Assay:^{^[2]}	Cell lines Primary mouse astrocytes Concentrations 10 μM Incubation Time 24 h Method Primary mouse astrocytes were stimulated with afatinib (10 μM), UNC2025 (10 μM), or pemigatinib (10 μM) for 24 hours. N2A neuronal cells were stimulated with ACM or control medium for 24 hours. Primary mouse astrocytes and N2A neuronal cells were detached and washed once in cold 1× PBS. Live/dead staining was performed. In addition, annexin V–propidium iodide staining was performed. Cells were washed once and resuspended in annexin V binding buffer before acquisition on a 3L Cytek Northern Lights flow cytometer. Analysis of flow cytometry data was performed with the OMIQ platform. (Data sourced from selleck products)
