In eukaryotes, a set of initiation factors (eIFs) interact with ribosomal subunits to initiate mRNA translation.{25211} A major step in initiation is the assembly of a large multiprotein complex that includes the cap-binding protein eIF4E and the multidomain adaptor protein eIF4G.{25211} 4EGI-1 is an inhibitor of the initiation of translation that blocks the interaction of eIF4G with eIF4E (KD = 25 μM).{25208} It directly binds eIF4E, competitively inhibiting an association with eIF4G that is necessary for cap-dependent translation.{25208} 4EGI-1 prevents the expression of oncogenic proteins in mammalian cancer cells, leading to apoptosis.{25208,25207,25213} Research with this inhibitor supports a role for normal eIF4E/eIF4G interaction in memory consolidation and excess interaction in autism spectrum disorders.{25212,25210,25206} 4EGI-1 also blocks translation in some viruses that do not require eIF4E or a cap structure for initiation.{25209}

    Cyclin-dependent kinases (CDKs) are key regulators of cell cycle progression and are therefore promising targets for cancer therapy. (R)-Roscovitine is a potent inhibitor of Cdk2/cyclin E with an IC50 value of 0.1 µM.{14988} It also inhibits Cdk7/cyclin H, Cdk5/p35, and cell division cycle (cdc)/cyclin B with IC50 values of 0.49, 0.16, and 0.65 µM, respectively.{14987,14988,14991} (R)-Roscovitine inhibits the growth of rapidly proliferating cells with an average IC50 value of 15.2 µM against a panel of 19 human tumor cell lines.{14988} In murine models of polycystic kidney disease, (R)-roscovitine effectively inhibited disease progression at doses of 50-100 mg/kg.{14564}

    PtdIns-(3,4,5)-P3-biotin (sodium salt) – 50 µg

    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}
