Uses

Used in Pharmaceutical Industry:
N-[2-Chloro-4-[(6,7-dimethoxy-4-quinolyl)oxy]phenyl]-N'-(5-methyl-3-isoxazolyl)urea is used as a potent VEGFR-1, 2, and 3 inhibitor, c-Kit and PDGFR inhibitor for its antitumor effects towards renal cell carcinoma. It suppresses angiogenesis by selectively inhibiting vascular endothelial growth factor, making it a valuable compound in the development of targeted cancer therapies.
Used in Drug Development:
N-[2-Chloro-4-[(6,7-dimethoxy-4-quinolyl)oxy]phenyl]-N'-(5-methyl-3-isoxazolyl)urea is used as a research tool in the development of novel VEGF receptor tyrosine kinase inhibitors. Its potent activity against multiple VEGFRs and other receptor tyrosine kinases, such as c-Kit and PDGFR, positions it as a potential candidate for further investigation in the treatment of various types of cancer.
Used in Preclinical Research:
N-[2-Chloro-4-[(6,7-dimethoxy-4-quinolyl)oxy]phenyl]-N'-(5-methyl-3-isoxazolyl)urea is utilized in preclinical studies to evaluate its efficacy and safety as a potential therapeutic agent. Its activity against multiple targets makes it an interesting compound for exploring synergistic effects in combination therapies and for identifying potential off-target effects that may impact its clinical utility.

In vitro

AV-951 is a novel quinoline-urea derivative. AV-951 blocks VEGF-dependent activation of mitogen-activated protein kinases and proliferation of endothelial cells.

In vivo

In vivo studies show that AV-951 also decreases the micro vessel density and suppresses VEGFR2 phosphorylation levels in tumor xenografts, especially at a concentration of 1mg/kg (p.o. administration). AV-951 shows almost complete inhibition of tumor xenografts growth (TGI>85%) in athymic rats. Another study in rat peritoneal disseminated tumor model shows that AV-951 could prolong the survival of the tumor-bearing rats with the MST of 53.5 days. AV-951 displays antitumor activity against many human tumor xenografts including lung, breast, colon, ovarian, pancreas and prostate cancer.

Mechanism of action

Tivozanib is a ?tyrosine kinase inhibitor that exerts its actions by inhibiting the ?phosphorylation of vascular endothelial growth factor receptor ?(VEGFR)-1, VEGFR-2 and VEGFR-3 and inhibits other kinases such as c-kit ?and platelet derived growth factor beta (PDGFR β).

Synthesis

The synthesis of?Tivozanib is as follows:Phenyl chlorocarbonate (601 g) was added dropwise to 3-amino-5-methylisoxazole (377 g), pyridine (1215 g), and N,N-dimethylacetamide (4 L) at 0°C, and the mixture was stirred at 20°C for 2 hr. 4-[(4-Amino-3-chlorophenol)oxy]-6,7-dimethoxyquinoline (847 g) was added to the reaction solution, and the mixture was stirred at 80°C for 5 hr. The reaction solution was cooled to 5°C. Thereafter, methanol (8.5 L) and water (8.5 L) were added thereto, and the mixture was neutralized with an aqueous sodium hydroxide solution. The resultant precipitate was collected by filtration, and the filtered product was slurried in water (8.5 L) for washing. The slurry was filtered, and the filtered product was then dried under the reduced pressure to give Tivozanib (1002 g, yield 86.1%).

Check Digit Verification of cas no

The CAS Registry Mumber 475108-18-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,7,5,1,0 and 8 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 475108-18:
(8*4)+(7*7)+(6*5)+(5*1)+(4*0)+(3*8)+(2*1)+(1*8)=150
150 % 10 = 0
So 475108-18-0 is a valid CAS Registry Number.
