Description

A kind of salt form of EGFR inhibitor, crystal form and preparation method thereof

Technical field

Salt form, crystal form the present invention relates to a kind of EGFR inhibitor of T790M mutation and preparation method thereof, further include described The application of salt form and crystal form in non-small cell lung cancer drug is treated.

Background technology

Protein tyrosine kinase is that phosphate group of a kind of catalysis on protein substrate is transferred to junket from ATP or GTP The enzyme of histidine residue.Receptor tyrosine kinase from extracellularly phosphorylation is caused to intracellular delivery signal by activating secondary letter Number path.Various kinds of cell process is utilized by these signals-modulatings, including propagation, carbohydrate, protein synthesis, blood vessel Generation, cell growth and cell survival.In addition, many diseases or illness are active not normal with one or more kinases, it is abnormal Or imbalance is related.

EGF-R ELISA belongs to transmembrane tyrosine kinase acceptor ErbB families, which includes EGFR (also referred to as ErbB or HER1), (HER2 the or neu genes) of ErbB2, (HER3) and ErbB4 (HER4) of ErbB3.In addition to HER3, With tyrosine kinase activity.EGFR/ErbB families tyrosine kinase receptor has in cell Proliferation, differentiation and apoptosis Indispensable effect, and therefore become the effective target for being used for preventing growth and metastasis of tumours.The epidermal growth factor of the first generation Sub- receptor tyrosine kinase inhibitors (in EGFR-TKI), including Gefitinib (J Med 2004；350:2129-39) and Lip river in distress For Buddhist nun (Lancet Oncol 2011；12:735-42), they are had been demonstrated in the advanced NSCLC with body cell Activating mutations It is effective in patient.These are mutated the kinase domain in encoding EGFR, as 19 extra of polynucleotides is shown The leucine of 858 on the in-frame deletion and 21 exons of son is replaced into arginic point mutation (L858R) (Nat Rev Cancer 2007；7:169-81).However, patient eventually causes to swell after first generation EGFR-TKIs is received due to drug resistance Knurl produces secondary growth.The secondary mutation that the threonine of No. 790 positions is replaced into methionine (T790M) most generally believes Resistance mechanism.This mutation is detected (N Engl in the tumour cell that the patient being in progress occurs in 50%~60% disease J Med 2005；353:207-8).Second generation EGFR-TKIs, such as Afatinib (Lancet Oncol 2014；15:213-22) With dacomitinib (Cancer 2014；120:Exploitation 1145-54) to overcome generation TKIs produce drug resistance.They Can be with the cysteine of irreversible upper 797 of covalent bond EGFR.Covalent mechanism is believed to overcome double-mutant to be increased The affinity of the ATP added.But cysteine -797 is present in the EGFR of form of ownership.Therefore the chemical combination of these second generations Thing, it is not only active to the EGFR of Activating mutations and secondary mutation but also also active to the EGFR of wild type.To wild type The suppression of EGFR is not believed to be helpful in its clinical efficacy, but can cause the side effect of fash and diarrhea (Curr.Med.Chem.2006,13,3483-3492)。

Therefore third generation EGFR-TKIs, including AZD9291 (Cancer Discov 2014；4:1046-61),CO-1686 (Cancer Res.2013；19:2240-2247) with HM61713 (US 2013011213), they are oral irreversible tools There is the EGFR-TKIs of Catastrophic selection, T790M mutation can be suppressed and traditional EGFR is mutated, and do not have to Wild type EGFR Effect.They have efficiently in T790M positive tumors, but they still have certain toxicity, as can still produce diarrhea, skin Rash, nausea even clinical side effects ((the J Clin Oncol 2014 such as hyperglycaemia；32:abstr 8009；J Clin Oncol 2014；32:abstr 8010).It will be apparent that a compound with more high activity and hypotoxicity can bring bigger benefit.

AstraZeneca AZD9291 is a kind of oral small molecule third generation epidermal growth factor tyrosine kinase inhibitor, AZD9291 is stronger for the specific binding capacity of medicament-resistant mutation T790M and sensitizing mutation site (19Del and L858R), therefore Drug resistant Patients with Non-small-cell Lung has good therapeutic effect after being treated for a line TKI, but since it is wild to EGFR Type also has certain suppression, therefore can clinically produce the side effects such as diarrhea, fash.

CO1686 is a kind of new, oral, selective depressant for treating EGFR saltant type Patients with Non-small-cell Lung, it It can suppress crucial activation and T790M medicament-resistant mutations, it makes Wild type EGFR signal leave unused, and has good tolerance, The metabolin that CO1686 is produced has inhibitory action to two targets of IGF1R and INSR, thus clinically side effect shows as high blood Sugar.
