Pralatrexate is a dihydrofolate reductase (DHFR) inhibitor (Ki = 13.4 pM) and antifolate.{39422} It inhibits growth of CCRF-CEM acute lymphocytic leukemia cells (IC50 = 0.04 μM), MDA-468, SK-BR-3, and ZR-75-1 breast cancer cells (IC50s = 0.11, 0.28, and 0.26 μM, respectively), and SK-LC8 and SK-LC16 non-small cell lung cancer cells (NSCLC; IC50s = 0.42 and 0.11 μM, respectively). In vivo, pralatrexate increases median survival from 21 to 40 days when administered in 4 doses of 15 mg/kg over 11 days in an H9 T cell lymphoma mouse xenograft model.{39423} Pralatrexate is transported into cells via the reduced folate carrier (RFC) and undergoes polyglutamation by folylpolyglutamate synthetase (FPGS) to a greater extent than methotrexate (Item No. 13960) or pemetrexed (Item No. 14269).{39424,39425} Formulations containing pralatrexate have been used in the treatment of relapsed or refractory peripheral T cell lymphoma.

  • 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.
