Biological Activity of SAR131675

DescriptionSAR131675 is an inhibitor of VEGFR3 with IC50/Ki of 23 nM/12 nM, respectively.
TargetsVEGFR3    
IC5023 nM (Ki=12 nM)     

Protocol

Kinase Assay [1]
Multiwell plates are precoated with a synthetic polymer substrate poly-Glu-Tyr (polyGT 4:1). The reaction is carried out in the presence of kinase buffer (10×: 50 mM HEPES buffer, pH 7.4, 20 mM MgCl2, 0.1 mM MnCl2, and 0.2 mM Na3VO4) supplemented with ATP and dimethyl sulfoxide (DMSO) for the positive control (C+) or SAR131675 (ranging from 3-1,000 nM). ATP is used at 30 μM for VEGFR-1 and VEGFR-3 and at 15 μM for VEGFR-2. The phosphorylated poly-GT is probed with a phosphotyrosine specific monoclonal antibody (mAb) conjugated to horseradish peroxidase and developed in the dark with the HRP chromogenic substrate (OPD). The reaction is then stopped by the addition of 100 μL 1.25 mol/L H2SO4, and absorbance is determined using an Envision spectrophotometer at 492 nm[1].

Cell Assay [1]
HLMVECs are seeded in 96-well plates coated with 0.3% gelatin (5000 cells per well). Cells are incubated in RPMI 0.1% FCS with VEGFA (10 ng/mL) VEGFC (300 ng/mL), VEGFD (300 ng/mL), or FGF2 (10 ng/mL) in the absence or presence of SAR131675. Five days later, viable cells are quantified with the cell Titer-glo luminescent cell viability assay[1].

Animal Administration [1]
Mouse: Sterile sponge disks impregnated with 200 μg of FGF2 or PBS are subcutaneously introduced on the back of anaesthetized mice. FGF2 is reinjected into the sponges the first 2 days. Daily oral treatment with SAR131675 (30, 100, and 300 mg/kg/d) started the day of sponge implantation. Seven days later, the animals are euthanatized and the sponges are removed, harvested, and lysed in RIPA buffer at 4°C. After a centrifugation at 6,000 × g, the supernatants are collected for further analysis[1].

Background on SAR131675

SAR131675 is a selective inhibitor of VEGFR-3 with IC50 value of 20nM [1].

SAR131675 is an ATP-competitive inhibitor. It inhibits recombinant human VEGFR-3 with IC50 value of 23nM and inhibits the kinase activity of VEGFR-3 with Ki value of 12nM. SAR131675 is found to be cell permeable and inhibits VEGFR-3 autophosphorylation in HEK cells with IC50 values ranging from 30nM to 50nM. SAR131675 shows IC50 values of >3μM and 235nM against VEGFR-1 and VEGFR-2, respectively. It also havs no inhibitory effect on a panel of 65 kinases, 107 nonkinase enzymes and receptors and on 21 ion channels. Moreover, SAR131675 inhibits lymphatic cell survival induced by VEGFC and VEGFD with IC50 values of 14nM and 17nM. On another hand, SAR131675 exerts inhibition of the migration induced by VEGFA or VEGFC with IC50 values of 100nM and <30nM in HLMVEC cells, respectively [1].

In vivo, SAR131675 abrogates lymphangiogenesis and angiogenesis induced by FGF2. It also shows antitumor activity in the mice models. Treatment with SAR131675 significantly reduces the tumor volume of 4T1 mammary carcinoma tumors [1]

Specific Inhibition of the VEGFR-3 Tyrosine Kinase by SAR131675 Reduces Peripheral and Tumor Associated Immunosuppressive Myeloid Cells.[Pubmed:24589997]

Cancers (Basel). 2014 Feb 28;6(1):472-90.

Myeloid derived suppressor cells (MDSCs) and tumor-associated macrophages (TAMs) represent prominent components in cancer progression. We previously showed that inhibition of the VEGFR-3 pathway by SAR131675 leads to reduction of TAM infiltration and tumor growth. Here, we found that treatment with SAR131675 prevents the accumulation of immunosuppressive blood and splenic MDSCs which express VEGFR-3, in 4T1 tumor bearing mice. Moreover we showed that soluble factors secreted by tumor cells promote MDSCs proliferation and differentiation into M2 polarized F4/80+ macrophages. In addition, cell sorting and transcriptomic analysis of tumor infiltrating myeloid cells revealed the presence of a heterogeneous population that could be divided into 3 subpopulations: (i) immature cells with a MDSC phenotype (GR1+/CD11b+/F4/80-); (ii) "immuno-incompetent" macrophages (F4/80high/CD86neg/MHCIILow) strongly expressing M2 markers such as Legumain, CD206 and Mgl1/2 and (iii) "immuno-competent"-M1 like macrophages (F4/80Low/CD86+/MHCIIHigh). SAR131675 treatment reduced MDSCs in lymphoid organs as well as F4/80High populations in tumors. Interestingly, in the tumor SAR131675 was able to increase the immunocompetent M1 like population (F4/80low). Altogether these results demonstrate that the specific VEGFR-3 inhibitor SAR131675 exerts its anti tumoral activity by acting on different players that orchestrate immunosuppression and cancer progression in a tumoral context: MDSCs in peripheral lymphoid organs and TAMs infiltrating the tumor.

SAR131675, a potent and selective VEGFR-3-TK inhibitor with antilymphangiogenic, antitumoral, and antimetastatic activities.[Pubmed:22584122]

Mol Cancer Ther. 2012 Aug;11(8):1637-49.

SAR131675 is a potent and selective VEGFR-3 inhibitor. It inhibited VEGFR-3 tyrosine kinase activity and VEGFR-3 autophosphorylation in HEK cells with IC(50) values of 20 and 45 nmol/L, respectively. SAR131675 dose dependently inhibited the proliferation of primary human lymphatic cells, induced by the VEGFR-3 ligands VEGFC and VEGFD, with an IC(50) of about 20 nmol/L. SAR131675 was found to be highly selective for VEGFR-3 versus 107 receptors, enzymes, ion channels, and 65 kinases. However, it was moderately active on VEGFR-2 with a VEGFR-3/VEGFR-2 ratio of about 10. SAR131675 had no antiproliferative activity on a panel of 30 tumors and primary cells, further showing its high specificity and indicating that SAR131675 is not a cytotoxic or cytostatic agent. SAR131675 was very well tolerated in mice and showed a potent antitumoral effect in several orthotopic and syngenic models, including mammary 4T1 carcinoma and RIP1.Tag2 tumors. Interestingly, it significantly reduced lymph node invasion and lung metastasis, showing its antilymphangiogenic activity in vivo. Moreover, treatment of mice before resection of 4T1 primary tumors was sufficient to prevent metastasis. Tumor-associated macrophages (TAM) play an important role in tumor growth and metastasis. The expression of VEGFR-3 on TAMs has been recently described. F4/80 immunostaining clearly showed that SAR131675 significantly reduced TAM infiltration and aggregation in 4T1 tumors. Taken together, SAR131675 is the first highly specific VEGFR-3-TK inhibitor described to date, displaying significant antitumoral and antimetastatic activities in vivo through inhibition of lymphangiogenesis and TAM invasion.
