Ulipristal acetate is a selective progesterone receptor modulator (SPRM) that binds to the human progesterone receptors PR-A and PR-B (EC50s = 8.5 and 7.7 nM, respectively), rabbit uterine PR (EC50 = 13.6 nM), and rabbit thymic glucocorticoid receptor (GR; EC50 = 15.4 nM).{40657} It is selective for human progesterone receptors over the human estrogen receptor (ER; EC50 = >10,000 nM). It inhibits growth of IGROV-1 and SKOV3 human ovarian cancer cells (IC50s = 15.5 and 31.5 μM, respectively) even after resistance to combined cisplatin (Item No. 13119) and paclitaxel (Item No. 10461) treatment has developed.{40658} Ulipristal acetate reverses the proliferative effect of progesterone on patient-derived germline mutant BRCA1 breast tissue xenografts in ovariectomized athymic mice.{40659} Ulipristal acetate (40 mg/kg, i.p.) administered to female mice within 6 hours of human chorionic gonadotropin (hCG) treatment inhibits ovulation.{40660} Formulations containing ulipristal acetate have been used as emergency contraceptives and to treat uterine fibroids.

    CAY10512 – 100 mg

    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. CAY10512 is a substituted trans-stilbene analog of resveratrol that is 100-fold more potent as measured by antioxidant activity. The IC50 value for inhibition of TNFα-induced activation of NF-κB by CAY10512 is 0.15 µM compared to 20 µM by resveratrol.{14545}

  • 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.
