Abstract:
Peptidomimetics that inhibit the interaction between MLL1 and WDR5 are disclosed. Methods of inhibiting MLL1 activity and methods of treating cancers also are disclosed.
Abstract:
The invention relates to diazo bicyclic Smac mimetics that are tethered through a covalent linker to give a bivalent species. Bivalent diazo bicyclic Smac mimetics function as inhibitors of Inhibitor of Apoptosis Proteins (IAPs). The invention also relates to the use of bivalent diazo bicyclic Smac mimetics for inducing or sensitizing cells to the induction of apoptotic cell death. Thus, compounds of the invention are useful in the treatment, amelioration, or prevention of hyperproliferative diseases such as cancer.
Abstract:
Provided herein are compounds, compositions, and methods in the field of medicinal chemistry. The compounds and compositions provided herein relate to spiro-oxindoles which function as antagonists of the interaction between p53 and MDM2, and their use as therapeutics for the treatment of cancer and other diseases.
Abstract:
The invention relates to heteroaryl-substituted bicyclic mimetics of Smac which function as inhibitors of Inhibitor of Apoptosis Proteins. The invention also relates to the use of these mimetics for inducing apoptotic cell death and for sensitizing cells to inducers of apoptosis.
Abstract:
The present invention provides a biomarker for selecting a patient for treatment with gossypol, wherein the biomarker comprises an elevated expression level of c-Myc, Mcl-1, or combination thereof, relative to the normal expression level of c-Myc, Mcl-1, or combination thereof. The present invention also provides methods for targeting patients for treatment with gossypol, wherein the patient has a disease, condition, or disorder that overexpresses c-Myc, Mcl-1, or combination thereof. The present invention also provides methods for treating or ameliorating a disease, condition, or disorder in a patient comprising determining the expression level of c-Myc, Mcl-1, or combination thereof in the patient and administering gossypol to the patient. In certain embodiments of the invention, the disease is cancer, and the cancer cells show elevated expression levels of c-Myc compared to non-cancerous cells. The invention also provides methods for overcoming Mcl-1-mediated chemoresistance comprising administering gossypol to a patient in need thereof.
