20110245304 | RIBONUCLEOTIDE REDUCTASE INHIBITORS AND METHODS OF USE - Provided herein are novel compounds that inhibit ribonucleotide reductase (RR) by binding to RRM2 and interfering with the activity of the RRM1/RRM2 holoenzyme. These inhibitors may be used to inhibit RR activity and to treat various conditions associated with RRM2 expression, such as for example certain cancer types, mitochondrial diseases, or degenerative diseases. | 10-06-2011 |
20120302815 | MULTI-VALENT POLY-UBL CHAIN INHIBITORS AND METHODS OF USE - A composition used to develop a reagent for investigating Ubl-modifications in cellular functions and in the treatment of cancer is provided. The composition comprises gold nanoparticle (AuNP)-ligand conjugates that include at least two components: gold nanoparticles (AuNPs) and modified ubiquitin- or ubiquitin-like interacting motif (UIM or ULIM) mimetics. In one embodiment, the modified ULM mimetic is a modified SUMO interaction motif (SIM) mimetic. According to the embodiments described herein, the compound inhibits ubiquitin- or ubiquitin-like protein (Ubl)-mediated protein-protein interactions and sensitizes cells to ionizing radiation. The modified UIM and ULIM mimetics may be conjugated to the AuNP such that each AuNP is conjugated to a plurality of modified UIM or ULIM mimetics. The modified ULIM mimetics may be conjugated to the AuNP via a thiol group. | 11-29-2012 |
20140155423 | BERBAMINE DERIVATIVES - The invention provides novel berbamine derivatives, and compositions or pharmaceutical compositions thereof. These berbamine derivatives have shown higher potency in killing cancer/tumor cells comparing to berbamine, and can be used in cancer/tumor treatments. | 06-05-2014 |
20140275224 | CYTOSINE DEAMINASE MODULATORS FOR ENHANCEMENT OF DNA TRANSFECTION - Compounds and methods are provided for enhancing or boosting the transfection rate or efficiency of mammalian cells by foreign DNA, such as bacterial plasmid DNA. Compounds, including natural products and inventive synthetic compounds can increase the effectiveness of uptake and incorporation of foreign DNA by mammalian cells, such as human cells, by suppression of DNA cytosine deamination, which is believed to be a mechanism by which these cells eliminate foreign DNA. Inhibition of the cytosine deaminase enzymes by compounds as described herein serves to provide more effective transfection of eukaryotic cells by plasmids including engineered gene sequences. Transfection can be used to study cellular processes, or to cure genetic diseases in human patients. The inventive materials and methods increase the efficiency and effectiveness of such transfection techniques. | 09-18-2014 |
