UN-No:
- 3077 / 9

Ro 5126766 is a dual inhibitor of MEK1 (IC50 = 160 nM) and Raf kinases (IC50s = 56, 19, and 8.2 nM for C-RAF, B-RAF, and B-RAFV600E, respectively).{45986} It is selective for these kinases over a panel of 254 additional kinases at 10 µM. Ro 5126766 (1 µM) decreases MEK and ERK phosphorylation in a panel of seven cancer cell lines expressing mutant K-RasG13D, K-RasQ61K, K-RasG12D, H-RasG12D, or B-RAFV600E at 1 µM. It inhibits proliferation of SK-MEL-28, SK-MEL-2, MIA PaCa-2, SW480, and HCT116 cancer cells (IC50s = 65, 28, 40, 46, and 277 nM, respectively) but not A549, HCT15, or PC3 cancer cells (IC50s = >1,000 nM for all).{45987} Oral administration of Ro 5126766 (25 mg/kg four times per day) reduces tumor growth in an HCT116 mouse xenograft model.{45986}

    CAY10512 – 100 mg

    The nuclear factor-κB (NF-κB) regulates the expression of numerous genes involved in immunity and inflammation, cellular stress responses, growth, and apoptosis. Resveratrol, a polyphenolic trans-stilbene, is a known inhibitor of the activation of NF-κB and exhibits activity against a wide variety of cancer cells. CAY10512 is a substituted trans-stilbene analog of resveratrol that is 100-fold more potent as measured by antioxidant activity. The IC50 value for inhibition of TNFα-induced activation of NF-κB by CAY10512 is 0.15 µM compared to 20 µM by resveratrol.{14545}

    The PtdIn phosphates play an important role in the generation and transduction of intracellular signals.{8344,4096,14518} PtdIns-(3,4,5)-P3-biotin is an affinity probe which allows the PIP3 to be detected through an interaction with the biotin ligand. This design allows PtdIns-(3,4,5)-P3-biotin to serve as a general probe for any protein with a high affinity binding interaction with inositol-(3,4,5)-triphosphate phospholipids, such as phosphatidylinositol 3-kinase, PTEN, or PH-domain-containing proteins.

  • A powerful effector in both the TetR and revTetR transcriptional regulator systems

    Anhydrotetracycline (hydrochloride) – 50 mg

    The tetracycline repressor (TetR) is a transcriptional regulator which normally binds tightly to its palindromic tetO operator DNA, blocking gene expression.{17508} Tet causes the repressor to dissociate from the DNA, allowing transcription to occur. A novel reverse TetR (revTetR) requires tetracycline as a co-repressor to bind tetO and block transcription.{17509,17510} Anhydrotetracycline (hydrochloride) is a powerful effector in both the tetracycline repressor (TetR) and reverse TetR (revTetR) systems, binding the Tet repressor 35-fold more strongly than Tet.{17508,17511} Moreover, anhydrotetracycline poorly binds the 30S ribosomal subunit, compared to Tet,{17512} so it does not act as a general inhibitor of translation and is a poor antibiotic. Perhaps related to this, the concentration of anhydrotetracycline that inhibits eukaryotic cell growth is more than a 1,000-fold above the dose that alters transcription through TetR.{17508}
