pdgfrα kinase inhibitor 1

PDGFRα kinase inhibitor 1 is a highly selective inhibitor of type II PDGFRα kinase (PDGFRα and PDGFRβ) with IC50 values of 132 nM and 6115 nM, respectively.

Cediranib (AZD2171) (AZD2171) is a highly potent (IC50 < 1 nmol L) ATP-competitive inhibitor of recombinant KDR tyrosine kinase in vitro, also inhibits Flt1 4 (IC50: 5 nM ≤3 nM), similar activity against PDGFRβ and c-Kit, selective more for VEGFR than PDGFR-α (36-fold), CSF-1R (110-fold), and Flt3 (1000-fold) in HUVEC cells.

Amuvatinib hydrochloride (MP470 hydrochloride) is an orally administered multi-targeted tyrosine kinase inhibitor effective against mutant forms of c-Kit, PDGFRα, Flt3, c-Met, and c-Ret, and it suppresses DNA repair by inhibiting the RAD51 protein, contributing to its antineoplastic activity[1][2][3][4].

AC708 is a small molecule CSF1R inhibitor that effectively inhibits CSF1R phosphorylation mediated by CSF-1 (IC50 = 26 nM) and IL-34 (IC50 = 33 nM). It also inhibited the activity of growth factor-dependent cells cultured in CSF-1 (IC50 = 38 nM) or IL-34

Chiauranib is a multi-target inhibitor against tumor angiogenesis and exhibits potent anticancer effects. Chiauranib potently inhibits the angiogenesis-related kinases (VEGFR1, VEGFR2, VEGFR3, PDGFRα and c-Kit), mitosis-related kinase Aurora B, and chronic inflammation-related kinase CSF1R, with IC50 values ranging from 1-9 nM.

Tyrosine kinase-IN-1 is a multi-targeted tyrosine kinase inhibitor that acts on KDR, Flt-1, FGFR1, and PDGFRα with IC50 values of 4 nM, 20 nM, 4 nM, and 2 nM, respectively.

Multi-kinase-IN-2 is an orally active inhibitor of angiokinases. multi-kinase-IN-2 significantly inhibits the activity of angiokinases such as VEGFR-1 2 3, PDGFRα β, FGFR-1, LYN and c-KIT kinases. -IN-2 significantly attenuates phosphorylation of AKT and ERK proteins, induces apoptosis and has anticancer effects.

Antiproliferative Agent-34 (Compound A14), a multitarget kinase inhibitor, demonstrates IC50 values of 177 nM for EGFR L858R T790M and 1567 nM for EGFR WT. Additionally, it inhibits JAK2, ROS1, FLT3, FLT4, and PDGFRα with respective IC50s of 30.93 nM, 106.90 nM, 108.00 nM, 226.60 nM, and 42.53 nM. In normoxic conditions, it suppresses the proliferation of H1975 and HCC827 cells with IC50 values below 40 nM, while under hypoxic conditions, its potency increases 4-6 fold, yielding IC50 values less than 10 nM [1].

GW694590A (UNC10112731) functions as a MYC protein stabilizer that enhances the levels of endogenous MYC protein. It also acts on receptor tyrosine kinases, inhibiting DDR2, KIT, and PDGFRα by 81%, 68%, and 67% at a concentration of 1 μM, respectively. As a protein kinase inhibitor, GW694590A affects both ATP-dependent and ATP-independent luciferases, potentially influencing the Fluc reporter gene [1].
