De Minimis - 2811 / 6.1

Clonidine is an agonist of α2-adrenergic receptors (α2-ARs; Kis = 61.66, 69.18, and 134.9 nM for α2A-, α2B-, and α2C-ARs, respectively).{40326} It stimulates [35S]GTPγS binding to HEK293 cell membranes expressing the human receptors with EC50 values of 26.92, 56.23, and 912.01 nM for α2A-, α2B-, and α2C-ARs, respectively. Clonidine also binds to I1-imidazoline sites in a variety of cell and tissue types (Kds = 4-15 nM).{46373} It induces relaxation of isolated mesenteric artery rings precontracted with norepinephrine (Item No. 16673) when used at a concentration of 10 μM.{25849} Clonidine (10 μM) also induces membrane hyperpolarization and reduces norepinephrine-induced depolarization in isolated mesenteric artery rings. Clonidine (0.1 and 1 μg/kg) reduces mean blood pressure and heart rate when administered via microinjection to the nucleus reticularis lateralis (NRL) of anesthetized normotensive cats.{36359} Formulations containing clonidine have been used in the treatment of hypertension.

    The nuclear factor-κB (NF-κB) regulates the expression of numerous genes involved in immunity and inflammation, cellular stress responses, growth, and apoptosis. Resveratrol, a polyphenolic trans-stilbene, is a known inhibitor of the activation of NF-κB and exhibits activity against a wide variety of cancer cells.

  • 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 – 25 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.
