Description

Comprise the Therapeutic combinations of PLK1 inhibitor and antitumor agent
The present invention relates generally to field of cancer, and more specifically offer comprises PLK1 inhibitor and one or many Planting the antineoplastic combinations of antitumor agent, this combination has good antitumor action.
Cancer is the cause of death that the mankind are main;Surgical operation, radiotherapy and chemotherapy are useful to anticancer Method.Particularly, combined chemotherapy (it is intended to by combination or more than one medicine is used in combination treats cancer) is a kind of The Therapeutic Method of widely accepted oncosis (such as cancer).In order to select antineoplastic combinations the most effectively and safely Being applied to the patient suffering from cancer, people several times make great efforts and are still carrying out effort.In order to reduce single medicine alone Time toxic action, and owing to having bigger effect when combining in some cases and be used alone than any one medicament, Combine by using the known antitumoral compounds antineoplastic agent different from one or more, strengthen known antitumor chemical combination The antitumor efficacy of thing is a kind of demand strongly experienced in field of anticancer therapy.
Expressing of PLK1 is the most visible in the normal structure of all propagation, but process LAN is but at a series of tumor (bag Include breast carcinoma, carcinoma of prostate, ovarian cancer, pulmonary carcinoma, gastric cancer and colon cancer) in just observation obtain.Once PLK1 quilt in cancerous cell RNAi exhaust, can be observed propagation suppression and reduction vigor (its cause cell cycle arrest the 4N DNA content stage with Rear apoptosis).Although in the mankind, describe 4 kinds of different PLKs family members, but this inhibition of enzyme activity or the consumption of PLK1 Exhaust swelling in the G2/M cell cycle arrest and apoptosis and xenograft models being just enough in inducing tumor cell system Tumor disappears.Additionally, for other PLKs, it has been described that the function of tumor suppressor gene, and report PLK2 and PLK3 (rather than PLK1) expresses in non-proliferative, differentiation postmitotic cells (such as neuron), and this points out PLK1 specificity Compound be likely to be of more preferable safety (see for example: Strebhardt K, et al., Nat Rev Cancer 2006;6 (4): 321-30).
It is a kind of received for treating extensive human cancer for using mitotic inhibitor in treatment of cancer Clinical strategy (see for example: Jackson JR, et al., Nature Reviews Cancer 2007;7,107-117).Purple China fir alkanes (paclitaxel and docetaxel) and vinca alkaloids (vincristine and vinblastine) are by stablizing micro-pipe or making Micro-pipe unstability (in by mitotic cell progression, there is catastrophic effect) and play a role.They are some tumor classes The first-line treatment medicine of type (including Hokdkin disease, non_hodgkin lymphoma, carcinoma of testis, neuronal cell tumor and Wilms tumor) Thing (vinca alkaloids) and be the second line treatment medicine in cisplatin-refractory ovarian, breast carcinoma, pulmonary carcinoma and the esophageal carcinoma Thing (taxanes).But, due to the effect during such as cell migration, phagocytosis and axonal transport of micro-pipe, the most considerable Observe these medicaments and there is some toxicity (such as peripheral neuropathy).
Protect with requirement described in patent application WO2008074788 (Nerviano Medical Sciences Srl.) The pyrazoloquinazolines class protected is effective inhibitor of PLK1, and is therefore applicable to treat proliferative disorders, particularly cancer.

***At 2,3,4,6,7,8 days with formula (I) compounds for treating;Treated with CPT11 at 1,5,9 days
Clear and definite synergism is created with formula (I) compound of CPT11 combination.When formula (I) compound combines with CPT11 Viewed T-C is simply added more than the intended T-C obtained by single therapy.Any one treatment group is not the most seen Observe toxicity.
Embodiment 11: formula (I) compound and the cells in vivo neurotoxin active of 5FU combination.
According to Council of the European Communities's directive/guide the 86/609/EECth, will be male purchased from the Balb of Harlan (Italy) Nude mouse is placed in the cage with sterilized paper filter cover, food and bedding and padding and acidifying water.It is subcutaneously implanted HT29 people's colon Tumor fragment.Treatment is started when tumor tangibly.By oral route by formula (I) compound with the agent of 45mg/kg every day Amount was used at the 2nd, 3,4,6,7 and 8 days.By intravenous route, 5FU is used at the 1st, 5 and 9 days with the dosage of 50mg/kg. During combination, formula (I) compound was used at the 2nd, 3,4,6,7 and 8 days, and 5FU used at the 1st, 5 and 9 days.Within every 3 days, measure Tumor growth and body weight.Tumor growth is assessed by caliper.Record two diameters and calculate tumor weight according to following equation Amount: length (mm) x width2/2.The evaluation of effect of antineoplaston is that the generation of the exponential growth postponing tumor (sees document Anticancer drugs 7:437-60,1996).This delay (T-C value) is defined as the swollen for the treatment of group (T) and matched group (C) Tumor reaches the difference of time (unit: sky) required for predetermined size (1g).The T-C that T-C value is the mono-medicine of > when drug regimen Value is accredited as synergism when being added, and is accredited as summation action when the T-C value of drug regimen is added equal to the T-C value of single medicine.
Toxicity is evaluated based on losing weight.Table 11 reports this result.

When formula (I) compound combines with 5FU, viewed T-C is simple with the intended T-C obtained by single therapy It is added similar, prompts for summation action.
Embodiment 12: formula (I) compound and the cells in vivo neurotoxin active of Avastin combination.
According to Council of the European Communities's directive/guide the 86/609/EECth, will be male purchased from the Balb of Harlan (Italy) Nude mouse is placed in the cage with sterilized paper filter cover, food and bedding and padding and acidifying water.
It is subcutaneously implanted HT29 human colon carcinoma tumor fragment.Treatment is started when tumor tangibly.By oral route by formula (I) compound was used at the 2nd, 3,4,6,7,8,10,11 and 12 days with the dosage of every day 45 and 60mg/kg by 10ml/kg volume. By intraperitoneal routes, Avastin is used at the 1st, 5,9 and 13 days with the dosage of 20mg/kg.During combination, formula (I) is changed Compound was used at the 2nd, 3,4,6,7,8,10,11 and 12 days, and Avastin was used at the 1st, 5,9 and 13 days.Within every 3 days, survey Amount tumor growth and body weight.Tumor growth is assessed by caliper.Record two diameters and calculate tumor according to following equation Weight: length (mm) x width2/2.The evaluation of effect of antineoplaston is that the generation of the exponential growth postponing tumor (sees document Anticancer drugs 7:437-60,1996).This delay (T-C value) is defined as the swollen for the treatment of group (T) and matched group (C) Tumor reaches the difference of time (unit: sky) required for predetermined size (1g).The T-C that T-C value is the mono-medicine of > when drug regimen Value is accredited as synergism when being added, and is accredited as summation action when the T-C value of drug regimen is added equal to the T-C value of single medicine. Toxicity is evaluated based on losing weight.Table 12 reports this result.

*Oral medication is carried out at 2,3,4,6,7,8,10,11,12 days.
**Treated by intravenous route at 1,5,9,13 days.
***At 2,3,4,6,7,8,10,11,12 days with formula (I) compounds for treating, used Avastin at 1,5,9,13 days Treatment.
Viewed T-C is obtained by single therapy with intended when formula (I) compound combines with Avastin T-C is simply added similar.Toxicity is not the most observed in any one treatment group.
Embodiment 13: formula (I) compound and the cells in vivo neurotoxin active of cytosine arabinoside combination.
