Aformoterol is the (R,R)-enantiomer of the β2-adrenergic receptor (β2-AR) agonist formoterol (Item No. 15584).{43065} It selectively binds to β1- over β2-ARs (Kds = 2.9 and 113 nM, respectively) as well as β3-adrenergic, B2 bradykinin, neurokinin 1 (NK1) and NK2 receptors when used at concentrations up to 3 μM. Aformoterol induces cAMP accumulation in cultured human bronchial epithelial cells. Ex vivo, aformoterol (0.01-1,000 nM) induces dose-dependent relaxation of guinea pig tracheal strips precontracted with carbamoylcholine (Item No. 14486), ovalbumin, or histamine (pD2s = 8.4, 9.5, and 9.5, respectively). In vivo, aformoterol reverses histamine- and ovalbumin-induced bronchoconstriction in guinea pigs (ED50s = 1 and 40 nmol/kg, respectively). Formulations containing aformoterol have been used in the treatment of chronic obstructive pulmonary disease (COPD).

  • 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.
