Arachidonoyl ethanolamide (AEA, Item No. 90050), also known as anandamide, is an endogenous ligand of the cannabinoid receptors.{2713} AEA is metabolized by fatty acid amide hydrolase (FAAH) to give arachidonic acid (Item No. 90010) and ethanolamine.{15373} ARN1203 is a fluorinated analog of AEA that serves as a substrate of FAAH (Km = 29 µM).{25931} Fluorinated substrates, like ARN1023, are used in ‘n-fluorine atoms for biochemical screening’ (n-FABS) assays, NMR functional assays that directly measure the conversion of the substrate into product.{25932} ARN1203 is used to perform n-FABS against FAAH to identify novel inhibitors.{25931, 25932,25933}
A fluorinated analog of AEA that serves as a substrate of FAAH (Km = 29 µM); used to perform n-FABS against FAAH to identify novel inhibitors

1,2-Dipalmitoyl-sn-glycero-3-PC (DPPC) is a zwitterionic glycerophospholipid commonly used in the formation of lipid monolayers, bilayers, and liposomes for use in a variety of applications.{14480,24261,14478,14479} It has been used in the formation of proteoliposomes for implantation of γ-glutamyl transpeptidase into human erythrocyte membranes.{14478} Incorporation of glycosphingolipid antigens into DPPC-containing liposomes increases the immunogenicity of the antigens in mice.{14479}

The PtdIn phosphates play an important role in the generation and transduction of intracellular signals.{8344,4096,14518} PtdIns-(3,4,5)-P3-biotin is an affinity probe which allows the PIP3 to be detected through an interaction with the biotin ligand. This design allows PtdIns-(3,4,5)-P3-biotin to serve as a general probe for any protein with a high affinity binding interaction with inositol-(3,4,5)-triphosphate phospholipids, such as phosphatidylinositol 3-kinase, PTEN, or PH-domain-containing proteins.

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.
