G-5555 is an inhibitor of p21-activated kinase 1 (PAK1; Ki = 3.7 nM), a non-receptor serine/threonine kinase involved in tumorigenesis.{37400} It is selective for PAK1 over the majority of targets in a panel of 235 kinases but does inhibit PAK2, PAK3, KHS1, LCK, MST3, MST4, SIK2, and YSK1 by greater than 70% with IC50 values ranging from 9 to 52 nM. G-5555 inhibits phosphorylation of MEK, a downstream target of PAK1, in EBC1 cells (IC50 = 69 nM). G-5555 (10, 20, and 30 mg/kg) dose-dependently reduces phosphorylation of MEK in tumors from an H292 non-small cell lung cancer (NSCLC) mouse xenograft model. G-5555 inhibits hERG channels less than 50% at a concentration of 10 μM, indicating the potential for a low risk of QT interval prolongation and potentially fatal arrhythmias.{37401}

  • A small molecule activator of stem cell renewal that allows the propagation of OG2 mES cells for at least 10 passages in an undifferentiated state; activity is mediated by the combined inhibition of RasGAP and ERK1 with Kd values of 98 and 212 nM

    SC-1 – 10 mg

    The maintenance of embryonic stem cells in culture typically requires feeder cells and various exogenous factors found in serum. Murine embryonic stem (mES) cells can be maintained in the absence of feeder cells and serum but require the leukemia inhibitor factor (LIF) and bone morphogenic protein (BMP) to prevent differentiation and promote self-renewal. SC-1 is a small molecule activator of stem cell renewal that allows the propagation of OG2 mES cells for at least 10 passages in an undifferentiated state.{14533} The activity of SC-1 is mediated by the combined inhibition of RasGAP and ERK1 with Kd values of 98 and 212 nM, respectively.{14533} Inhibition of RasGAP increases Ras signaling via the PI3-kinase pathway which promotes self-renewal, whereas inhibition of ERK blocks differentiation.

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

    Anhydrotetracycline (hydrochloride) – 250 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}
