Boceprevir-d9 is intended for use as an internal standard for the quantification of boceprevir (Item No. 18379) by GC- or LC-MS. Boceprevir is an inhibitor of hepatitis C virus (HCV) non-structural protease 3/4A (NS3/4A; Ki = 14 nM for the HCV genotype 1b enzyme).{30614} Boceprevir inhibits HCV replication in Huh7 cells (EC50 = 200 nM).{36164} It also inhibits severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) main protease (Mpro; Ki = 1.8 µM) and reduces cytopathic effects of SARS-CoV-2 in Vero cells (EC50 = 1.31 µM).{58053} Formulations containing boceprevir have been used in the treatment of HCV.

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.
