Quinoline derivative and use thereof
View Patent ↗Provided are a novel quinoline derivative, or a pharmaceutically acceptable salt, a hydrate, or a metabolite formed by metabolism in any form thereof, and use thereof in preparing a medicine for preventing and/or treating indications associated with angiogenesis. The quinoline derivative is an ideal and high-efficiency VEGFR inhibitor, and is able to be used to treat or prevent tumour growth and other metastasis growth diseases associated with angiogenesis.
1. A quinoline derivative having a structure represented by Formula (I), a pharmaceutically acceptable salt, or a hydrate, thereof,
wherein:
R 1 is NHR 5 , wherein R 5 is five-membered unsaturated heterocycle containing 2 N, which is substituted by one methyl;
R 2 is selected from hydrogen, halogen, hydroxy, alkoxy and cyano;
R 3 and R 4 are independently selected from OR 6 , C(O)NH 2 and C(O)NHR 6 , wherein R 6 is C 1 -C 6 alkyl or halogenated alkyl;
X is selected from O;
non-exchangeable hydrogen is unsubstituted, or partially or fully substituted by deuterium in the quinoline derivative having the structure represented by Formula (I), or the pharmaceutically acceptable salt, or the hydrate thereof.
2. The quinoline derivative, the pharmaceutically acceptable salt, or the hydrate thereof according to claim 1 , wherein R 2 is Cl or F.
3. The quinoline derivative, the pharmaceutically acceptable salt, or the hydrate thereof according to claim 1 , wherein R 3 and R 4 are independently selected from OR 6 and C(O)NH 2 , the R 6 is methyl or ethyl.
4. The quinoline derivative, the pharmaceutically acceptable salt, or the hydrate, thereof according to claim 1 , wherein R 5 is
5. The quinoline derivative, the pharmaceutically acceptable salt, or the hydrate thereof according to claim 1 , wherein R 3 and R 4 are independently selected from C(O)NH 2 and C(O)NHR 6 , the R 6 is methyl or ethyl.
6. The quinoline derivative, the pharmaceutically acceptable salt, or the hydrate thereof according to claim 1 , wherein the quinoline derivative is the compound represented by the following structural formula,
7. A medicine for preventing and/or treating indications associated with angiogenesis, containing the quinoline derivative, the pharmaceutically acceptable salt, or the hydrate thereof according to claim 1 .
