5,7-Dichlorokyneurenic acid (5,7-DCKA) is a derivative of kynurenic acid (Item No. 16792) and an NMDA receptor antagonist (Ki = 40 nM in a radioligand binding assay).{41941} It selectively inhibits glycine- over kainate-induced NDMA currents at 15 μM in Xenopus oocytes expressing rat NMDA receptors. 5,7-DCKA reduces NMDA-induced neurotoxicity in primary rat cortical neurons by 55 to 90% when used at concentrations ranging from 1 to 10 μM. In vivo, 5,7-DCKA (0.97-97 nmol) reverses mechanical hyperalgesia in magnesium-deficient rats in a dose-dependent manner.{41942} It blocks the positive ionotropic effect, hypertension, and increase in myocardial oxygen demand induced by electrical stimulation of the paraventricular nucleus (PVN) in anesthetized rabbits.{41943} 5,7-DCKA also increases social interaction time in the social interaction test and time spent in the open arms of the elevated plus maze, indicating anxiolytic-like activity, as well as disinhibits conflict responding in the Cook and Davidson conditioned conflict paradigm.{41944}

  • 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 – 5 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.
