Therapeutic applications of pro-apoptotic benzodiazepines
View Patent ↗Benzodiazepine compounds, and methods for using those compounds are provided. Some of the benzodiazepine compounds include 1,4-benzodiazepine-2-one and 1,4-benzodiazepine-2,5-dione compounds of structures: wherein R 1 , R 2 , R 3 and R 4 are as defined. The invention also includes enantiomers, pharmaceutically acceptable salts, prodrugs or derivatives of the benzodiazepine compounds. Any one or more of these benzodiazepine compounds can be used to treat a variety of dysregulatory disorders related to cellular death. Such disorders include autoimmune disorders, inflammatory conditions, hyperproliferative conditions, viral infections, and atherosclerosis. In addition, the above compounds can be used to prepare medicaments to treat the above-described dysregulatory disorders. The benzodiazepines can also be used in drugs screening assays and other diagnostic methods.
1. A method of treating a disorder selected from the group consisting of an autoimmune disorder, a hyperproliferative disorder, a chronic inflammatory condition, and atherosclerosis, comprising administering an effective amount of a benzodiazepine compound to a subject suffering from said autoimmune disorder, said hyperproliferative disorder, or said chronic inflammatory condition, wherein said benzodiazepine compound is represented by:
or an enantiomer or pharmaceutically acceptable salt thereof, wherein:
R 1 is aliphatic;
R 2 is
R 3 is hydrogen or an aliphatic group having 1-8 carbons and 1-20 hydrogens; and
R 4 is halogen.
2. The method of claim 1 , wherein R 1 is methyl.
3. The method of claim 1 , wherein R 3 is hydrogen.
4. The method of claim 1 , wherein the benzodiazepine compound is the following:
or a pharmaceutically acceptable salt thereof.
5. The method of claim 1 , wherein the disorder is an autoimmune disorder selected from the group consisting of graft versus host disease, rheumatoid arthritis, and systemic lupus erythematosus.
6. The method of claim 1 , wherein the disorder is rheumatoid arthritis.
7. The method of claim 1 , wherein the disorder is asthma.
8. The method of claim 1 , wherein the disorder is Crohn's disease.
9. The method of claim 1 , wherein the disorder is psoriasis.
10. The method of claim 1 , wherein the disorder is a chronic inflammatory condition.
