1-Deoxysphinganine is an atypical sphingolipid that lacks the C1-hydroxyl group of canonical sphinganine and is formed when serine palmitoyltransferase condenses palmitoyl-CoA with alanine instead of serine during sphingolipid synthesis.{17311} Plasma levels of 1-deoxysphinganine are increased in patients with hereditary sensory and autonomic neuropathy type 1 (HSAN1), an inherited neuropathy associated with serine palmitoyltransferase gene mutations, and in patients with glycogen storage disease type I (GSDI).{42288,36918} Deoxysphingolipids, including 1-deoxysphinganine, are not converted to canonical sphingolipids or fatty acids and accumulate in cells, particularly in the mitochondria where 1-deoxysphinganine induces mitochondrial fragmentation and dysfunction.{42285} It also accumulates in LLC-PK1 cells and in mouse liver and kidney following application or administration, respectively, of the ceramide synthase inhibitor fumonisin B1 (Item No. 62580).{17311} 1-Deoxysphinganine is neurotoxic to dorsal root ganglion neurons in vitro, decreasing neurite length and inducing neurite contraction when used at a concentration 1 µM.{42288} It is cytotoxic to DU145 cells (IC50 = ~2 µM) but stimulates DNA synthesis in Swiss 3T3 cells when used at a concentration of 1 µM.{17311,36917}

  • 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}

  • 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.
