1 . (canceled)
2 . A compound represented by the following structural formula:
or a pharmaceutically acceptable salt or a stereoisomer thereof.
3 . A pharmaceutical composition comprising an effective amount of the compound of claim 2 or a pharmaceutically acceptable salt thereof, and a pharmaceutically acceptable carrier.
4 . A method of treating a cancer comprising administering to a subject in need thereof an effective amount of a compound of claim 2 , or a pharmaceutically acceptable salt thereof, wherein the cancer is a carcinoma of the bladder, breast, colon, kidney, epidermis, liver, lung, oesophagus, gall bladder, ovary, pancreas, stomach, cervix, thyroid, nose, head and neck, prostate, or skin; a hematopoietic tumor of lymphoid lineage; a hematopoietic tumor of myeloid lineage; thyroid follicular cancer; a tumor of mesenchymal origin; a tumor of the central or peripheral nervous system; melanoma; seminoma; teratocarcinoma; osteosarcoma; xeroderma pigmentosum; keratoacanthoma; or Kaposi's sarcoma.
5 . A method of inhibiting activity of a cyclin-dependent kinase (CDK) in a subject, said method comprising administering to the subject an effective amount of a compound of claim 2 , or a pharmaceutically acceptable salt thereof.
6 . The method of claim 5 , wherein the subject has a cancer, such as a carcinoma of the bladder, breast, colon, kidney, epidermis, liver, lung, oesophagus, gall bladder, ovary, pancreas, stomach, cervix, thyroid, nose, head and neck, prostate, or skin; a hematopoietic tumor of lymphoid lineage; a hematopoietic tumor of myeloid lineage; thyroid follicular cancer; a tumor of mesenchymal origin; a tumor of the central or peripheral nervous system; melanoma; seminoma; teratocarcinoma; osteosarcoma; xeroderma pigmentosum; keratoacanthoma; or Kaposi's sarcoma.
7 . The method of claim 6 , wherein the hematopoietic tumor of lymphoid lineage is leukemia, acute lymphocytic leukemia, chronic lymphocytic leukemia, B-cell lymphoma, T-cell lymphoma, multiple myeloma, Hodgkin's lymphoma, non-Hodgkin's lymphoma, hairy cell lymphoma, or Burkett's lymphoma.
8 . The method according to claim 6 , wherein the cancer is pRb + breast cancer, or hormone receptor (HR)-positive (e.g., estrogen receptor positive (ER + ), progesterone receptor positive (PR + ), or ER + PR + ), HER2/neu-negative breast cancer.
9 . The method of claim 8 , wherein the cancer is advanced or metastatic or recurrent breast cancer.
10 . The method of claim 9 , wherein the breast cancer is in an adult woman, or a postmenopausal woman.
11 . The method of claim 8 , further comprising administering a second agent selected from: an aromatase inhibitor, a Selective Estrogen Receptor Modulator (SERM), a pure antiestrogen with no estrogen agonist activity, a compound that temporarily suppresses ovarian function (e.g., estrogen and/or progesterone production) such as a gonadotropin-releasing hormone (GnRH) agonist or a luteinizing hormone-releasing hormone (LH-RH) agonist, a compound that inhibits CYP3A4, or a monoclonal antibody or an antigen-binding fragment thereof against IGF-1/IGF-2.
12 . The method of claim 11 , further comprising administering an immune checkpoint inhibitor (such as a PD-1 inhibitor, a PD-L1 inhibitor, or a CTLA-4 inhibitor), a receptor Tyr kinase inhibitor, and/or an antagonist of hormone receptor (such as estrogen receptor).
13 . A method of treating a cancer comprising administering to a subject in need thereof an effective amount of a compound of Formula (I):
or a pharmaceutically acceptable salt thereof, wherein the cancer is a carcinoma of the bladder, breast, colon, kidney, epidermis, liver, lung, oesophagus, gall bladder, ovary, pancreas, stomach, cervix, thyroid, nose, head and neck, prostate, or skin; a hematopoietic tumor of lymphoid lineage; a hematopoietic tumor of myeloid lineage; thyroid follicular cancer; a tumor of mesenchymal origin; a tumor of the central or peripheral nervous system; melanoma; seminoma; teratocarcinoma; osteosarcoma; xeroderma pigmentosum; keratoacanthoma; or Kaposi's sarcoma.
14 . A method of inhibiting activity of a cyclin-dependent kinase (CDK) in a subject, said method comprising administering to the subject an effective amount of a compound of Formula (I):
or a pharmaceutically acceptable salt thereof.
15 . The method of claim 14 , wherein the subject has a cancer, such as a carcinoma of the bladder, breast, colon, kidney, epidermis, liver, lung, oesophagus, gall bladder, ovary, pancreas, stomach, cervix, thyroid, nose, head and neck, prostate, or skin; a hematopoietic tumor of lymphoid lineage; a hematopoietic tumor of myeloid lineage; thyroid follicular cancer; a tumor of mesenchymal origin; a tumor of the central or peripheral nervous system; melanoma; seminoma; teratocarcinoma; osteosarcoma; xeroderma pigmentosum; keratoacanthoma; or Kaposi's sarcoma.
16 . The method of claim 15 , wherein the hematopoietic tumor of lymphoid lineage is leukemia, acute lymphocytic leukemia, chronic lymphocytic leukemia, B-cell lymphoma, T-cell lymphoma, multiple myeloma, Hodgkin's lymphoma, non-Hodgkin's lymphoma, hairy cell lymphoma, or Burkett's lymphoma.
17 . The method according to claim 15 , wherein the cancer is pRb + breast cancer, or hormone receptor (HR)-positive (e.g., estrogen receptor positive (ER + ), progesterone receptor positive (PR + ), or ER + PR + ), HER2/neu-negative breast cancer.
18 . The method of claim 17 , wherein the cancer is advanced or metastatic or recurrent breast cancer.
19 . The method of claim 18 , wherein the breast cancer is in an adult woman, or a postmenopausal woman.
20 . The method of claim 17 , further comprising administering a second agent selected from: an aromatase inhibitor, a Selective Estrogen Receptor Modulator (SERM), a pure antiestrogen with no estrogen agonist activity, a compound that temporarily suppresses ovarian function (e.g., estrogen and/or progesterone production) such as a gonadotropin-releasing hormone (GnRH) agonist or a luteinizing hormone-releasing hormone (LH-RH) agonist, a compound that inhibits CYP3A4, or a monoclonal antibody or an antigen-binding fragment thereof against IGF-1/IGF-2.
21 . The method of claim 20 , further comprising administering an immune checkpoint inhibitor (such as a PD-1 inhibitor, a PD-L1 inhibitor, or a CTLA-4 inhibitor), a receptor Tyr kinase inhibitor, and/or an antagonist of hormone receptor (such as estrogen receptor).
