Abstract

The present invention relates to a compositions for and methods of cancer treatment in which compounds of Formula I or Formula II. In some aspects, the treatment of B-cell Lymphoma or other hematopoietic cancers is encompassed. In other aspects, the invention provides methods for treating particular types of hematopoietic cancers, such as B-cell lymphoma, using a combination of one or more compounds of Formula I or Formula II. Combination therapy with, for example, a class of therapeutics known as 26S proteasome inhibitors, for example, Bortezomib, are also included. In another aspect the present invention relates to autoimmune treatment with compounds of Formula I or Formula II. In another aspect, this invention relates to methods for identifying compounds, for example, compounds of the BH3 mimic class, that have unique in vitro properties that predict in vivo efficacy against B-cell lymphoma tumors and other cancers as well as autoimmune disease.

Claims (90)

1. A method for treating chronic myeloid leukemia, pancreatic cancer, hepatocellular carcinoma, esophageal squamous cell carcinoma, melanoma, human non-small cell lung cancer, breast cancer, colon cancer, or rectal cancer, comprising administering an effective amount of a compound of Formula II,

or a stereoisomer thereof, tautomer thereof, solvate thereof, or a pharmaceutically acceptable salt thereof, to a patient in need thereof,

wherein:

Ar 1 is C 5-10 heteroaryl which is optionally substituted with one or more substituent R 1 wherein the substituents may be the same or different;

R 1 is independently selected from hydrogen, substituted C 1-6 alkyl, and unsubstituted C 1-6 alkyl;

R 2 and R 3 are each independently selected from hydrogen, substituted or unsubstituted C 1-6 alkyl, substituted or unsubstituted straight or branched C 1-10 alkyl, C 2-10 alkenyl, or C 2-10 alkynyl, substituted or unsubstituted C 3-10 cycloalkyl, substituted or unsubstituted C 5-8 cycloalkenyl, substituted or unsubstituted C 7-20 alkyl, substituted or unsubstituted C 1-10 aminoalkyl, substituted or unsubstituted C 5-10 aryl, and substituted or unsubstituted saturated or unsaturated 3-11 member heteroaryl or heteroarylalkyl containing 1, 2, 3, or 4 heteroatoms selected independently from N, O, S, and S(O) 2 , or R 2 and R 3 may be combined with the nitrogen to which they are attached to form a 3, 4, 5, 6, or 7 membered heterocycle in which one or more of the carbons may be substituted with a heteroatom selected from O, N, and S and in which any of the hydrogens of the heterocycle may be substituted with C 1-6 alkyl, F, Cl, Br, I, cyano, C 1-6 alkoxy, or C 6-10 aryloxy; and

R 4 and R 5 are independently selected from hydrogen, substituted or unsubstituted C 1-6 alkyl, substituted or unsubstituted C 1-6 aminoalkyl, and substituted or unsubstituted saturated or unsaturated 3-11 member heteroaryl or heteroarylalkyl containing 1, 2, 3, or 4 heteroatoms selected independently from N, O, S, and S(O) 2 .

2. The method of claim 1 , wherein Ar 1 is selected from the group consisting of furanyl and oxazolyl.

3. The method of claim 1 , wherein R 1 is selected from the group consisting of hydrogen and alkyl.

4. The method of claim 1 , wherein R 2 is selected from the group consisting of hydrogen and alkyl.

5. The method of claim 1 , wherein R 3 is selected from the group consisting of hydrogen, alkyl, heteroaryl, and substituted aryl.

6. The method of claim 1 , wherein R 4 is selected from the group consisting of hydrogen and as part of an unsaturated heterocyclic group.

7. The method of claim 1 , wherein R 5 is selected from the group consisting of heteroaryl, aminoalkyl, and as part of an unsaturated heterocyclic group.

8. The method of claim 1 , wherein the compound is selected from the group consisting of

2-(furan-2-yl)-6-(pyridin-2-ylamino)-N-(pyridin-3-yl)quinoline-4-carboxamide (24);

6-((2-(benzyl(methyl)amino)ethyl)amino)-2-(furan-2-yl)-N-(pyridin-3-yl)quinoline-4-carboxamide (25);
