Abstract

The present invention relates to compounds that inhibit KRas G12C. In particular, the present invention relates to compounds that irreversibly inhibit the activity of KRas G12C, pharmaceutical compositions comprising the compounds and methods of use therefor.

First claim

We claim:

1. A compound, wherein the compound is:

or a pharmaceutically acceptable salt thereof.

2. A pharmaceutical composition, comprising a therapeutically effective amount of a compound of claim 1 , and a pharmaceutically acceptable excipient.

3. A method for inhibiting KRas G12C activity in a cell, comprising contacting the cell in which inhibition of KRas G12C activity is desired with an effective amount of a compound of claim 1 , pharmaceutically acceptable salts thereof or pharmaceutical compositions containing the compound of claim 1 , or pharmaceutically acceptable salt thereof.

4. A method for treating a KRas G12C-associated cancer comprising administering to a patient having a KRas G12C-associated cancer a therapeutically effective amount of a compound of claim 1 , or a pharmaceutically acceptable salt thereof, alone or combined with a pharmaceutically acceptable carrier, excipient or diluents.

5. The method of claim 4 , wherein the therapeutically effective amount of the compound is between about 0.01 to 100 mg/kg per day.

6. The method of claim 4 , wherein the therapeutically effective amount of the compound is between about 0.1 to 50 mg/kg per day.

7. The method of claim 4 , wherein the KRas G12C-associated cancer is selected from the group consisting of Cardiac: sarcoma selected from angiosarcoma, fibrosarcoma, rhabdomyosarcoma, and liposarcoma, myxoma, rhabdomyoma, fibroma, lipoma and teratoma; Lung: bronchogenic carcinoma selected from squamous cell, undifferentiated small cell, undifferentiated large cell, and adenocarcinoma, alveolar carcinoma, bronchiolar carcinoma, bronchial adenoma, sarcoma, lymphoma, chondromatous hamartoma, mesothelioma, and non-small cell lung cancer; Gastrointestinal: esophagus selected from squamous cell carcinoma, adenocarcinoma, leiomyosarcoma, and lymphoma, stomach selected from carcinoma, lymphoma, and leiomyosarcoma, pancreas selected from ductal adenocarcinoma, insulinoma, glucagonoma, gastrinoma, carcinoid tumors, and vipoma, small bowel selected from adenocarcinoma, lymphoma, carcinoid tumors, Kaposi's sarcoma, leiomyoma, hemangioma, lipoma, neurofibroma, and fibroma, large bowel selected from adenocarcinoma, tubular adenoma, villous adenoma, hamartoma, and leiomyoma; Genitourinary tract: kidney selected from adenocarcinoma, Wilm's tumor (nephroblastoma), lymphoma, and leukemia, bladder and urethra selected from squamous cell carcinoma, transitional cell carcinoma, and adenocarcinoma, prostate selected from adenocarcinoma and sarcoma, testis selected from seminoma, teratoma, embryonal carcinoma, teratocarcinoma, choriocarcinoma, sarcoma, interstitial cell carcinoma, fibroma, fibroadenoma, adenomatoid tumors, and lipoma; Liver: hepatoma, cholangiocarcinoma, hepatoblastoma, angiosarcoma, hepatocellular adenoma, and hemangioma; Biliary tract: gall bladder carcinoma, ampullary carcinoma, cholangiocarcinoma; Bone: osteogenic sarcoma, fibrosarcoma, malignant fibrous histiocytoma, chondrosarcoma, Ewing's sarcoma, malignant lymphoma, multiple myeloma, malignant giant cell tumor chordoma, osteochondroma, benign chondroma, chondroblastoma, chondromyxofibroma, osteoid osteoma and giant cell tumors; Nervous system: skull selected from osteoma, hemangioma, granuloma, xanthoma, and osteitis deformans, meninges selected from meningioma, meningiosarcoma and gliomatosis, brain selected from astrocytoma, medulloblastoma, glioma, ependymoma, germinoma, glioblastoma multiform, oligodendroglioma, schwannoma, retinoblastoma, congenital tumors and spinal cord neurofibroma; Gynecological: uterus selected from endometrial carcinoma, granulosa-thecal cell tumors, Sertoli-Leydig cell tumors, dysgerminoma, and malignant teratoma, vulva selected from squamous cell carcinoma, intraepithelial carcinoma, adenocarcinoma, fibrosarcoma, and melanoma, vagina selected from clear cell carcinoma, squamous cell carcinoma, botryoid sarcoma, fallopian tubes; Hematologic: blood selected from myeloid leukemia, acute lymphoblastic leukemia, chronic lymphocytic leukemia, myeloproliferative diseases, multiple myeloma, and myelodysplastic syndrome, Hodgkin's disease, non-Hodgkin's lymphoma; Skin: malignant melanoma, basal cell carcinoma, squamous cell carcinoma, Kaposi's sarcoma, moles dysplastic nevi, lipoma, angioma, dermatofibroma; and Adrenal glands: neuroblastoma.

8. The method of claim 7 , wherein the cancer is non-small cell lung cancer.

9. A method for treating cancer in a patient in need thereof, the method comprising (a) determining that the cancer is associated with a KRas G12C mutation; and (b) administering to the patient a therapeutically effective amount of a compound of claim 1 or a pharmaceutically acceptable salt thereof, or a pharmaceutical composition thereof.
