Abstract
The invention discloses the substituted quinazoline analog derivative with Aurora kinase inhibitory activity and its applications.General formula(Ⅰ)Or(Ⅱ)Compound represented or its pharmaceutically acceptable salt, hydrate, solvate, polymorph, tautomer or prodrug.
Description
Technical field
The present invention relates to the substituted quinazoline analog derivative with Aurora kinase inhibitory activity and its applications.
Background technology
Cancer and other hyperproliferative diseases are characterized in uncontrolled cell Proliferation.Cell Proliferation normal regulating
The gene for losing the cell passage for being often as entire cell cycle progress is damaged and occurs.Research shows that
In eukaryocyte, the orderly cascade Mach-Zehnder interferometer of protein phosphorylation the cell cycle.Identified at present has weight in this cascade
The protease of several families to be acted on.Compared with normal structure, the activity of many above-mentioned kinases significantly increases in human tumour.
This may be caused by protein expression level improves or the expression of Assisted Activation albumen or resistance albumen changes.
Aurora A coding adjust the cell cycle serine-threonine protein kinase enzyme (referring to Trends in CellBiology,
2001,11,49-54, Adams etc.) it participates in adjusting spindle formation, centrosome maturation, chromosome differentiation and cytokinesis process,
There is key effect to the stability for maintaining genome.The study found that the overexpression of Aurora A easily leads to cell mitogenic
Abnormal division, it is closely related with the formation of tumour.Aurora A is in many cancer cells (such as lung cancer, breast cancer, the carcinoma of the rectum, first
Shape gland cancer, cancer of pancreas) in over-express, inhibit Aurora A activity can cause tumour cell polyploid aggregation, promote
Into Apoptosis, block cell Proliferation.Using Aurora A as target spot carry out antitumor drug research and development also increasingly by
To the attention of people.Aurora A is just expressed and activates in mitosis, they are invalid for non-proliferative cell, and
The growth rate of most of normal cells and unhappy in human body.Therefore Aurora A inhibitor belongs to targeting anti-tumor medicine
Object, compared with other non-specific cell cytotoxic drugs, by the advantage with bigger.
The Aurora A inhibitor studied at present is mainly ATP competitiveness kinase inhibitors, mainly by with ATP pockets
With reference to competitively inhibition Aurora A is active.ATP pockets mainly include three regions:Hydrophobic region inside kinases,
Hinge area among kinases and in external solvent can and area.And the Aurora A inhibitor studied at present is also main
Including three parts:Fatty contents, Hydrogenbond part, water-soluble portion.They respectively with ATP pockets corresponding region knot above
It closes.
The high activity Aurora A inhibitor of existing report is broadly divided into full Aurora A inhibitor, selectivity
AuroraA kinase inhibitors and selectivity Aurora B kinase inhibitors, following several structures are into clinical research
Aurora A inhibitor structure:
Vertex Standard (Vertex) drugmaker in the U.S.'s reported Aurora A kinases and quinazoline for the first time in 2003
Close object N- (3- cyclopropyl -1H- pyrazoles -5- bases) -2- phenylquinazoline -4- amine compound crystal structures.Its patent
Involved compound structure is as follows in (US7361492B2, WO2003092607A2) patent.The compound pyrazoles side chain
On three N atoms can form hydrogen bond action, in the Loop regions of kinases, kinases and the compound with the hinge area residue of kinases
Phenyl ring between there are pi-pi accumulation effects.
Vertex companies and Merck (Merck) company have developed jointly first Aurora A inhibitor VX-680 (again
Name MK-0457) (WO2004000833A1).The molecular structure is in Y shapes, and the pyrimidine ring at center is located at the hydrophobic region of kinases, with swashing
There is hydrophobic effect between enzyme amino acid residue;Amino-containing pyrazoles side chain stretches into the hinge area of kinases, with its amino acid residue
There is crucial hydrogen bond action;Side chain containing phenyl stretches into kinases hydrophobic region;Piperazine sidechain is then stretched over enzyme by the active region of enzyme
Solvent can and area.The study found that VX-680 has good inhibiting effect, IC to AuroraA, B and C50Value respectively 0.6,
18 and 4.6nM can inhibit colorectal cancer, breast cancer, prostate cancer, cancer of pancreas, melanoma, tumor colli, leukaemia
Etc. the proliferation of numerous tumour cells.2006, VX-680 entered clinical II phase research, is mainly used for the obstinate chronic bone for the treatment of
Myelogenous leukemia and acute lymphatic leukemia.Research find the drug can cause patient QTc extend risk (QTc is electrocardio
Time difference between the T waves and Q waves that are corrected on figure, QTc extensions are easy to cause arrhythmia cordis), in November, 2007, Merck terminated
II clinical trial phase (Expert Opin.Investing Drugs.2009,18,379) of VX-680.
When the pyrimidine 2- bit substituents of VX-680 are become styryl by CASI drugmakers (original name EntreMed), obtain
Compound ENMD 981693 show preferable cell activity, and can selectively inhibit Aurora A kinases, made
Into L-TARTARIC ACID salt (ENMD-2076).ENMD-2076 is a kind of orally available efficient AuroraA inhibitor, to Aurora A's
Inhibitory activity IC50It is worth for 14nM, the inhibitory activity IC of Aurora B50About 350nM, while be also angiogenesis kinase inhibition
Agent acts on the target spots such as VEGFR, Flt-3 and FGFR3.67 oophoromas, colorectal cancer patients progress ENMD-2076 are resisted swollen
Knurl is tested, which shows good antitumor action, (intravascular including important target spot VEGFR2 antitumor in blood plasma
Skin growth factor receptor 2) content be decreased obviously.The researchers such as Diamond are in ENMD-2076 to triple negative breast cancer
(TNBC) it is found in the research of hypotype and human epidermal growth factor receptor 2 (HER2) positive subgroup, ENMD-2076 is female sharp to lacking
Plain expression of receptor or without HER-2 overexpressions breast cancer cell have potent inhibiting effect.II phase carried out now
Clinical test mainly includes advanced metastatic triple negative breast cancer TNBC (NCT01639248), clear cell carcinoma of ovary
(NCT01914510) it is ground with late period or metastatic soft tissue sarcoma (NCT01719744), treatment liver fibrolamellar cancer (FLC)
III clinical trial phase will be entered by studying carefully.
In addition, there are also patent (WO2002000649A1, WO2003055491A1, WO2004058781A1,
WO2004113324A1, CN104098551A, US7951820B2) quinazoline derivative is reported available for inhibiting Aurora
Kinases:
The new compound with Aurora kinase inhibitory activity of exploitation, at this stage, is of great significance.
Invention content
The purpose of the present invention is to provide the substituted quinazoline analog derivative with Aurora kinase inhibitory activity and its answer
