Embodiment 1

[0112] 3-Isopropoxy-4-methylnitrobenzene (1)

[0113] Add 60g (0.39mol) of 3-hydroxy-4-methylnitrobenzene and 100g (0.72mol) of potassium carbonate into a 500ml three-necked flask, dissolve in 300ml of acetone, stir mechanically, and slowly add 50ml of 2-bromopropane ( 0.50mol), react at 40°C for 6 hours. Then the reaction liquid was poured into 1000 ml of water, extracted three times with chloroform, the extract was concentrated, and vacuum-dried to obtain 72.2 g of a brownish-yellow liquid product with a yield of 95%. Molecular formula: C10H13NO3, molecular weight: 195.22

Abstract

The invention discloses a making method of compound I and drug composition and application to treat tumour, which is 3-nitrile quinoline derivant (I) as dual-inhibitor protein kinase of tyrosine and nitric oxide synthase, wherein G1, G2, G3, G4, X, Z and n are defined as instruction.

Description

technical field [0001] The invention relates to the field of medicinal chemistry, in particular to a class of 3-cyanoquinoline derivatives which are dual inhibitors of tyrosine protein kinase and nitric oxide synthase. The invention also discloses its preparation method and a pharmaceutical composition containing it. And the purposes for treating tumor diseases. Background technique [0002] Protein tyrosine kinase (PTK) is a family of protein kinases that can catalyze the transfer of γ-phosphate on ATP or GTP from the donor to the acceptor tyrosine residue of the protein substrate. Cell regulatory processes (e.g. mitosis, cell differentiation, development, tumor formation, angiogenesis, apoptosis, cell formation and adhesion, cell cycle regulation, cell growth regulation, T and B cell activation, response to extracellular stimuli, neural Transmitter signaling, platelet activation, transcriptional regulation, glucose uptake) play an important role. However, in some cases, ...
