Leupeptin is a reversible inhibitor of cysteine, serine, and threonine proteases that is produced naturally by Streptomyces.{22713} It has been reported to inhibit cathepsin B (Ki = 6 nM), calpain (Ki = 10 nM), trypsin (Ki = 35 nM), plasmin (Ki = 3.4 μM), and kallikrein (Ki = 19 μM), and has no effect against chymotrypsin, elastase, renin, or pepsin.{22713} Leupeptin has been shown to be protective of auditory hair cells exposed to disruptive noise or ototoxic aminoglycoside-type antibiotics.{23480,23481} It is also widely used as a protein purification tool to prevent proteases present in tissue samples from degrading the protein of interest.

    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.

    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.
