Abstract: The present invention relates to novel derivatives of glycyrrhetinic acid, compositions comprising said derivatives and their use in the treatment of conditions or diseases that benefits from an upregulation of PPAR? and/or a downregulation of the expression or activity of one or more specificity (Sp) proteins, such as cancer, diabetes and Huntington's disease.

Abstract: The present invention relates to novel derivatives of glycyrrhetinic acid, compositions comprising said derivatives and their use in the treatment of conditions or diseases that benefit from an upregulation of PPAR&ggr; and/or a downregulation of the expression or activity of one or more specificity (Sp) proteins, such as cancer, diabetes and Huntington's disease.

Abstract: Provided herein are methods to suppress specificity protein (Sp) activity in a cell associated with a cell proliferative disease. The methods are effective to inhibit a microRNA in the cell using an antisense microRNA oligonucleotide which results in an increase in expression of a specificity protein (Sp) suppressor gene thereby inducing Sp degradation, apoptosis or growth arrest by releasing inhibitors of G2/M (Myt-1) or inhibition. Also provided are methods of treating a cancer using the antisense microRNA oligonucleotide. In addition the present invention provides antisense microRNA-27a oligonucleotides useful in the methods described herein.

Abstract: Provided herein provided herein are novel analogs and derivatives of betulinic acid. Also provided is a method for inhibiting an activity of one or more specificity protein (Sp) transcription factors cells associated with a neoplastic disease using betulinic acid, betulinic acid analog(s) and/or derivative(s) effective to decrease expression of a microRNA with concomitant increase in Sp suppressor gene expression. The betulinic acid analogs and derivatives also are effective in methods provided herein for inhibiting proliferation of cells associated with a neoplastic disease for treating a cancer or for reducing toxicity of a cancer therapy in a subject via administration of an analog or derivative of betulinic acid and, optionally, another anticancer drug.

Abstract: The present invention provides a method for inducing ligand-dependant Nur77 activation in a cell by contacting the cell with an effective dose of an agonist of Nur77. Also provided is a method for treating a mammal having a disease affected by modulation of Nur77 activity as well as a method for inducing apoptosis in a cell. The Nur77 agonists are preferably diindolylmethanes, and more preferably, methlylene-substituted diindolylmethanes. A representative example of the Nur77 agonists is a 1,1-bis (3?-indolyl)-1-(p-substituted phenyl) methane.
