NSC 185058 is an inhibitor of ATG4B, a cysteine protease that activates LC3B during the initiation of autophagy.{37384} It inhibits ATG4B cleavage of LC3B-GST (IC50 = 51 µM) and reduces LC3B lipidation induced by starvation in Saos-2 cells. NSC 185058 (100 µM) reduces starvation-induced autophagy and prevents autophagic vacuole formation in Saos-2 and MDA-MB-468 cells. It decreases phosphorylation of ribosomal protein S6 (RPS6) only marginally and does not affect phosphatidylinositol 3-kinase (PI3K) activity, indicating a direct role on ATG4B rather than through the mammalian target of rapamycin (mTOR) and PI3K signaling pathways. NSC 185058 (100 mg/kg) decreases autophagic vacuoles in vivo in mouse liver, inhibits tumor growth in an osteosarcoma nude mouse xenograft model, and decreases the number of autophagic vacuoles in osteosarcoma tumors.

  • 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.
