Methiocarb-d3 is intended for use as an internal standard for the quantification of methiocarb (Item No. 25627) by GC- or LC-MS. Methiocarb is a carbamate pesticide with insecticidal, molluscicidal, acaricidal, and bird repellant properties.{43317,43318,43319,43320,43323} It inhibits acetylcholinesterase (AChE) activity and is toxic to the western flower thrip (F. occidentalis; IC50 = 2.1 μM; LC50 = 3.26 ppm).{43318} Methiocarb is also toxic to the land snail M. obstructa (LD50 = 27.4 μg/snail) and the citrus mite A. pelekassi, inducing 94% mortality when used at a concentration of 0.5 ppm.{43317,43319} It reduces the seasonal percentages of cotton bolls infested with pink bollworm (P. gossypiella) to 4%, compared with 65% infestation in untreated controls, when applied to cotton fields at a concentration of 1.86 lb/acre.{43323} Methiocarb reduces damage to grapes by song birds when applied to vineyards at a concentration of 2.5 lbs AI per 100 gal water per acre.{43320} It is an estrogen receptor α (ERα) and ERβ agonist (EC20s = 19.87 and 20.24 μM, respectively) and an androgen receptor antagonist (IC50 = 13.89 μM) in cell-based reporter assays.{43321} It is toxic to juvenile rainbow trout (O. mykiss) and guppies (P. reticulata) with LC50 values of 0.8 and 1.48 mg/L, respectively, at 48 hours of exposure.{43322} Formulations containing methiocarb have been used in the agricultural control of pests.

  • 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 – 1 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) – 500 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}
