VE-822 is an inhibitor of ataxia-telangiectasia mutated (ATM) Rad3-related protein kinase (ATR), a regulator of DNA damage repair, with Ki and IC50 values of in vitro.{36517} It is selective for ATR over ATM (Ki = 34 nM; IC50 = 2,600 nM) as well as DNA-PK, mTOR, and PI3Kγ (Kis = >4,000, >1,000, and 220 nM, respectively). In cultured COLO 205 colorectal cancer cells, VE-822 (80 nM) reduces the IC50 of the topoisomerase 1 inhibitor SN-38 (Item No. 15632) by at least 8-fold.{36519} In a mouse xenograft model, it delays the growth of radiation-treated PSN-1 pancreatic cancer xenografts by 2-3-fold relative to radiation alone when administered at a dose of 60 mg/kg. VE-822 also enhances the tumoricidal effects of cisplatin (Item No. 13119) against primary human lung cancer xenografts and the effects of the topoisomerase inhibitor irinotecan (Item No. 14180) against COLO 205 colorectal tumors in mice.{36519,36518}

    CAY10512 – 50 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 – 1 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.
