Uses
Used in Pharmaceutical Industry:
Fruquintinib|HMPL-013 is used as a third-line regimen for the treatment of advanced non-small cell lung cancer in humans. It targets VEGFR1, 2, and 3 tyrosine kinases, playing a crucial role in inhibiting tumor growth and angiogenesis.
Used in Cancer Research:
Fruquintinib|HMPL-013 is used as a research tool for studying the role of VEGFR and other kinases in cancer progression. Its ability to inhibit VEGF-A-induced proliferation in HUVECs and VEGF-C-induced proliferation in HLECs makes it a valuable compound for understanding the mechanisms of tumor angiogenesis and the development of potential therapeutic strategies.
Used in Preclinical Cancer Models:
Fruquintinib|HMPL-013 is used in various mouse xenograft models, such as BGC-823, HT-29, Caki-1, and NCI H460, to evaluate its efficacy in reducing tumor growth. Administered at doses of 0.5-20 mg/kg per day for 21 days, it has shown significant tumor growth reduction, highlighting its potential as a therapeutic agent in cancer treatment.
in vitro
fruquintinib was found to inhibit vegfr2 with an ic50 of 25 nmol/l. the kinase selectivity of fruquintinib was evaluated against a panel of 253 kinases. the results showed that fruquintinib inhibited vegfr family members with weak inhibition of ret, fgfr-1 and c-kit kinases [1].
in vivo
anti-tumor activity of fruquintinib was evaluated in a variety of tumor xenografts. the results from gastric cancer bgc-823 model seemed to indicate that the drug concentration needs to be at least maintained above ec85 for around 8 hours in order to achieve >80% tumor growth inhibition. bgc-823 was found to be most sensitive to fruquintinib [1].
IC 50
33 nmol/l, 35 nmol/l and 0.5 nmol/l for vegfr1, 2, 3

Check Digit Verification of cas no
The CAS Registry Mumber 1194506-26-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,4,5,0 and 6 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1194506-26:
(9*1)+(8*1)+(7*9)+(6*4)+(5*5)+(4*0)+(3*6)+(2*2)+(1*6)=157
157 % 10 = 7
So 1194506-26-7 is a valid CAS Registry Number.
