Inhibitors, Agonists, Screening Data SheetBIOLOGICAL ACTIVITY: PZM21 is a potent and selective μ opioid receptor agonist with an EC50 of 1.8 nM.IC50 & Target: EC50: 1.8 nM (μ opioid receptor)[1]In Vitro: PZM21 has no detectable κOR or nociceptin receptor agonist activity–it is actually an 18 nM κOR antagonist–while it is a500–fold weaker δOR agonist, making it a selective μOR agonist. At hERG, PZM21 has an IC50 of between 2 and 4 μM, 500– to1,000–fold weaker than its potency as a μOR agonist. Signalling by PZM21 and other μOR agonists appears to be mediated primarilyby the heterotrimeric G protein Gi/o, as its effect on cAMP levels is eliminated by pertussis toxin and no activity is observed in acalcium release assay [1].In Vivo: PZM21 is a potent Gi activator with exceptional selectivity for μOR and minimal β–arrestin–2 recruitment. Unlike morphine,PZM21 is more efficacious for the affective component of analgesia versus the reflexive component and is devoid of both respiratorydepression and morphine–like reinforcing activity in mice at equi–analgesic doses. PZM21 displays dose–dependent analgesia in amouse hotplate assay, with a per cent maximal possible effect (% MPE) of 87% reached 15 min after administration of the highestdose of drug tested [1].PZM21 has a long–lasting analgesic effect on CNS mediated–pain responses, but does not cause respiratorydepression and constipation, two key side effects of opioid agonists. PZM21 does not exhibit the type of biomarker responses, suchas hyperlocomotion or conditioned place preference response, that are observed when morphine and other opioids are used andare associated with reinforcement and addiction[2].PROTOCOL (Extracted from published papers and Only for reference) Animal Administration:[1]Mouse: PZM21 is dissolved in 0.9% sodium chloride. Mice are injected with either vehicle, morphine (5mg/kg, or 10 mg/kg), TRV130 (1.2 mg/kg) or PZM21 (10 mg/kg; 20 mg/kg; or 40 mg/kg). After injection of drug, the analgesiceffect expressed as percentage maximum possible effect (%MPE) is measured at 15, 30, 60, 90 and 120 min after drug treatment[1].References: [1].

Inhibitors, Agonists, Screening Data SheetBIOLOGICAL ACTIVITY: LY2109761 is an orally active, selective TGF–β receptor type I/II (TβRI/II) dual inhibitor with Ki of 38 nM and 300 nM, respectively, andnegatively affects the phosphorylation of Smad2.IC50 & Target: Ki: 38 nM (TβRI), 300 nM (TβRII)In Vitro: LY2109761 significantly inhibits the growth of L3.6pl/GLT soft agar colonies in a dose–dependent manner, and results inappr 33% inhibition at 2 μM and 73% inhibition at 20 μM. Targeting TβRI/II kinase activity with LY2109761 (5 μM) almostcompletely suppresses both the basal and TGF–β1–stimulated migration of L3.6pl/GLT cells[1]. LY2109761 induces adose–dependent reduction in phosphorylation of Smad–2. HLE endogenous phosphorylation of Smad–2 is inhibited by LY2109761.LY2109761 blocks migration on different ECM proteins and invasion of both HLE and HLF through a 3–dimensional structure.LY2109761 increases E–cadherin mRNA expression after 24 hours and protein levels after 48 hours[2]. LY2109761 pretreatmentreduces clonogenic survival in cell cultures of U87MG and T98 following radiation, resulting in an increase in the radiosensitivitywith a DEF0.1 of 1.30 and 1.37, respectively[3].In Vivo: LY2109761 (50 mg/kg, p.o.) greatly reduces the tumor volume and increases the median survival duration of the mice to45.0 days. The mice treated with LY2109761 develop significantly fewer metastatic lesions and, in some of them, no metastaticlesion, as indicated by the GFP signal, can be identified in the abdomen[1]. LY2109761 enhances radiation–induced tumor growthdelay in a U87MG subcutaneous xenograft tumor model in BALB/c nude mice. LY2109761 increases survival in an orthotopical CSLCglioblastoma model and enhanced antitumor activity of radiation[2].PROTOCOL (Extracted from published papers and Only for reference) Cell Assay: LY2109761 is dissolved in 100% DMSO at a stock concentration of 10 mM.[1]L3.6pl/GLT cells are washed twice with coldPBS and lysed at 4°C into RIPA buffer (50 mM Tris HCl [pH 8], 150 mM NaCl, 1% NP–40, 0.5% sodium deoxycolate, and 0.1% SDS).Tumor and liver specimens are homogenized into RIPA buffer with an electric homogenizer and then maintained in constant agitationfor two hours at 4°C. The lysates are cleared by centrifugation. Each lysate (20 μg of protein) is separated by 8% SDS–PAGE andprobed with polyclonal rabbit antibodies against total ERK1/2, TβRI, and TβRII or with monoclonal mouse antibodies againstphosphorylated Smad2, total Smad2, phosphorylated ERK1/2, and phosphorylated and total JNK. Immunoreactive proteins arevisualized with Lumi–Light Western blotting substrate according to the manufacturer's instructions. phosphorylated Smad2/Smad2band density ratios are calculated using the ImageQuant software.Animal Administration: LY2109761 is dissolved in the SX–1292 oral vehicle (1% sodium carboxymethylcellulose, 0.5% sodiumlauryl sulfate, and 0.05% antifoam). [1]Fifty mice are randomLy allocated into five groups (n=5 mice per group) to receive p.o. vehiclefor 50 μL of LY2109761 or 50 mg/kg LY2109761 twice a day p.o. On day 0, mice are anesthetized with 1.5% isofluorane–air mixture, asmall left abdominal flank incision is created, and the spleen is carefully exteriorized. L3.6pl/GLT or C5LM2/GLT cells (1.0×105 cells/50μL of HBSS), cultured in the presence of LY2109761 (5 μM) or DMSO from day ?5 to day 0, are inoculated into the spleen with aProduct Name:LY2109761Cat.

BIOLOGICAL ACTIVITY: GW4869 is a noncompetitive neutral sphingomyelinase inhibitor with an IC50 of 1 μM.IC50 & Target: IC50: 1 μM (neutral sphingomyelinase)[1]In Vitro: GW4869 (10 μM) partially inhibits TNF–induced sphingomyelin (SM) hydrolysis, and 20 μM of the compound is protectedcompletely from the loss of SM. The addition of 10–20 μM GW4869 completely inhibits the initial accumulation of ceramide,whereas this effect is partially lost at later time points (24 h). The action of GW4869 occurs downstream of the drop in glutathione.GW4869 is able, in a dose–dependent manner, to significantly protect from cell death. These protective effects are accompanied bysignificant inhibition of cytochrome c release from mitochondria and caspase 9 activation, therefore localizing N–SMase activationupstream of mitochondrial dysfunction[1]. In Vivo: Pre–treatment with GW4869 significantly impairs release of both exosomes and pro–inflammatory cytokines (TNF–α, IL–1β,IL–6) in RAW264.7 macrophages. At 12 h after LPS treatment or CLP surgery, WT mice pretreated with GW4869 displays loweramounts of exosomes and pro–inflammatory cytokines in the serum than control PBS–injected mice. Accordingly, GW4869treatment diminishes the sepsis–induced cardiac inflammation, attenuates myocardial depression and prolongs survival[2]. PROTOCOL (Extracted from published papers and Only for reference) Kinase Assay:[1]B. cereu sphosphatidylcholine–PLC is incubated in the presence or absence of 10 μM GW4869 in a reaction mixturecontaining 100 mM Tris, pH 7.2, 25% glycerol, 20 mM p–nitrophenyl/phosphorylcholine, and production of p–nitrophenol isquantified spectrophotometrically at 410 nm. Protein phosphatase 2A from bovine kidney is incubated in the presence or absence ofGW4869 in buffer containing 50 mM Tris, pH 7.4, 1 mM dithiothreitol, 100 μM MnCl2, and 20% glycerol, and phosphatase activity ismeasured[1].Cell Assay: GW4869 is routinely stored at -80 °C as a 1.5 mM stock suspension in Me2SO. Right before use, the suspension issolubilized by the addition of 5% methane sulfonic acid (MSA) (2.5 μl of 5% MSA in sterile double–distilled H2O are added to 50μL of GW4869 stock suspension).[1]Cells are treated with GW4869 for 30 min and then TNF is added in 10 μL/well. At the indicatedtime points, 25 μL of MTT stock solution are added to each well and incubated at 37 °C in 5% CO2 for 3 h. The cell viability is usingthe MTT assay[1].Animal Administration: GW4869 is dissolved in DMSO (0.005%).[2]Mouse: The mice are randomly assigned to four groups: PBS,GW4869, PBS+LPS and GW4869+LPS (n=5 per group). GW4869 is intraperitoneally (i.p.) injected at one dose of 2.5μg/g. Mice inthe PBS+LPS group are pre–injected i.p. with PBS 1 h prior to an i.p. injection of LPS (25 μg/g). Mice in the group of GW4869+LPSare pre–injected i.p. with GW4869 (2.5μg/g) for 1 h, followed by an i.p. injection of LPS (25 μg/g, 100μl). Mice receive injections ofPBS to a comparable volume (100μl) as controls. The survival rate of the PBS+LPS and GW4869+LPS groups are monitored every 6h for a 36 h period[2].Product Name:GW4869Cat.
