Small molecule BCL-2 functional converters as cancer therapeutics
Methods for inducing growth inhibition or apoptosis of Bcl-2-expressing cells and treatments of Bcl-2 expressing cancers are provided. Additionally, assays for agents that can induce apoptosis of Bcl-2 expressing cells are disclosed.
1. A method of treating Bcl-2-expressing cancer in a subject, comprising administering to the subject in need of cancer treatment, a therapeutically effective amount of a compound
selected from the group consisting of:
(a) 5-chloro-N-(2-ethoxyphenyl)-2-[(4-methoxybenzoyl)amino]benzamide,
(b) 3,5-dichloro-N-(2-ethoxyphenyl)-2-[(3-nitrobenzoyl)amino]benzamide,
(c) 3-chloro-N-(2-{[(2-methoxyphenyl)amino]carbonyl}phenyl)-4-methylbenzamide,
(d) 2-[(4-methoxybenzoyl)amino]-N-(2-{[(2-methoxyphenyl)amino]carbonyl}-phenyl)benzamide,
(e) 2,4-dichloro-N-(4-chloro-2-{[(2-ethoxyphenyl)amino]carbonyl}phenyl)-benzamide, and
(f) N-(4-chloro-2-{[(2-ethoxyphenyl)amino]carbonyl}phenyl)-2-furamide,
wherein the compound contacts a Bcl-2-expressing cancer cell.
2. The method of claim 1 , wherein the cancer is breast cancer, blood cancer, lymphoma, lung cancer, melanoma, renal cancer, thyroid cancer, endometrial cancer, skin cancer, pancreatic cancer, glioma, colorectal cancer, ovarian cancer, cervical cancer, or liver cancer.
3. The method of claim 1 , further comprising administering an effective amount of an agent that increases Bcl-2 expression.
4. The method of claim 1 , wherein the method is further used in combination with radiation therapy.
5. The method of claim 1 , further comprising administering an effective amount of folate or leucovorin.
6. The method of claim 1 , wherein the cancer is resistant to paclitaxel.
7. A method of treating breast cancer, lung cancer, lymphoma, blood cancer, melanoma, renal cancer, thyroid cancer, endometrial cancer, skin cancer, pancreatic cancer, glioma, colorectal cancer, ovarian cancer, cervical cancer, or liver cancer in a subject, comprising administering to the subject, a therapeutically effective amount of a compound
selected from the group consisting of:
(a) 5-chloro-N-(2-ethoxyphenyl)-2-[(4-methoxybenzoyl)amino]benzamide,
(b) 3,5-dichloro-N-(2-ethoxyphenyl)-2-[(3-nitrobenzoyl)amino]benzamide,
(c) 3-chloro-N-(2-{[(2-methoxyphenyl)amino]carbonyl}phenyl)-4-methylbenzamide,
(d) 2-[(4-methoxybenzoyl)amino]-N-(2-{[(2-methoxyphenyl)amino]carbonyl}-phenyl)benzamide,
(e) 2,4-dichloro-N-(4-chloro-2-{[(2-ethoxyphenyl)amino]carbonyl}phenyl)-benzamide, and
(f) N-(4-chloro-2-{[(2-ethoxyphenyl)amino]carbonyl}phenyl)-2-furamide,
wherein the compound contacts a Bcl-2-expressing cancer cell.
8. The method of claim 7 , further comprising administering an effective amount of an agent that increases Bcl-2 expression.
9. The method of claim 7 , wherein the method is further used in combination with radiation therapy.
10. The method of claim 7 , further comprising administering an effective amount of folate or leucovorin.
11. The method of claim 7 , wherein the cancer is resistant to paclitaxel.
