Ki: 0.66 nM (neurokinin)[1]
体外研究 (In Vitro)
Rolapitant has a high affinity for the human NK1 receptor with a Ki of 0.66 nM and high selectivity over the human NK2 and NK3 subtypes of more than 1000-fold, as well as preferential affinity for human, guinea pig, gerbil and monkey NK1 receptors over rat, mouse and rabbit[1].
上海金畔生物科技有限公司 has not independently confirmed the accuracy of these methods. They are for reference only.
体内研究 (In Vivo)
Rolapitant reverses NK1 agonist-induced foot tapping in gerbils following both intravenous and oral administration up to 24 hours at a minimal effective dose (MED) of 0.1 mg/kg. Rolapitant is active at 0.1 and 1 mg/kg in both acute and delayed emesis models in ferrets, respectively, consistent with clinical data for other NK1 antagonists. Clinical efficacy of anti-emetics is highly correlated with efficacy in the ferret emesis model, suggesting rolapitant is a viable clinical candidate for this indication[1].

SCH772984 (12.5-50 mg/kg; i.p.; twice daily for 14 days) leads to 98% tumor regression[1]. Dose-dependent antitumor activity is also observed in the KRAS-mutant pancreatic MiaPaCa model, with 36% regression at 50 mg/kg twice daily. Importantly, tumor regression is accompanied by robust inhibition of ERK phosphorylation in tumor tissue. SCH772984 is well tolerated on this schedule as measured by morbidity, lethality, or body weight loss[1].

体外研究 (In Vitro)
Dinaciclib (SCH 727965) is a potent DNA replication inhibitor that blocks thymidine (dThd) DNA incorporation in A2780 cells with an IC50 of 4 nM. Dinaciclib (100 nM) inhibits phosphorylation of the retinoblastoma (Rb) tumor suppressor protein and induces accumulation of the p85 PARP caspase cleavage product[1]. In vitro cell growth of pancreatic cancer cells is inhibited by Dinaciclib (SCH727965) in a dose-dependent manner. Upon incubation with Dinaciclib for 72 h, the GI50s are approximately 10 and 20 nM for MIAPaCa-2 and Pa20C cells, respectively. These results are consistent with studies of Dinaciclib in other cancer cell lines. In soft agar assays, 5 to 10 nM of Dinaciclib significantly reduces colony formation and anchorage independent growth of MIAPaCa-2 cells. Moreover, in vitro cell migration of Pa20C and MIAPaCa-2 cells is significantly reduced by Dinaciclib-concentrations starting from 2-5 nM, as demonstrated using BD FluoroChrom, modified Boyden Chamber and wound healing assays[2].
MCE has not independently confirmed the accuracy of these methods. They are for reference only.
体内研究 (In Vivo)
Dinaciclib (8, 16, 32, and 48 mg/kg, i.p.) results in tumor inhibition by 70%, 70%, 89%, and 96%, respectively; Dinaciclib (SCH 727965) is well tolerated, and the maximum body weight loss in the highest dosage group is 5%. Dinaciclib has a short plasma half-life in mouse. A dose of 5 mg/kg Dinaciclib given i.p. in mice is associated with a plasma half-life of ~0.25 hour[1]. Treatment with Dinaciclib (SCH727965) given as twice weekly i.p. doses of 40 mg/kg for 4 weeks causes significant tumor growth inhibition (TGI) in 10/10 (100%) of low-passage subcutaneous pancreatic xenografts tested[2].

Kinase Assay [1]
Recombinant cyclin/CDK holoenzymes are purified from Sf9 cells engineered to produce baculoviruses that express a specific cyclin or CDK. Cyclin/CDK complexes are typically diluted to a final concentration of 50 μg/mL in a kinase reaction buffer containing 50 mM Tris-HCl (pH 8.0), 10 mM MgCl2, 1 mM DTT, and 0.1 mM sodium orthovanadate. For each kinase reaction, 1 μg of enzyme and 20 μL of a 2 μM substrate solution (a biotinylated peptide derived from histone H1) are mixed and combined with 10 μL of diluted Dinaciclib (SCH 727965). The reaction is started by the addition of 50 μL of 2 μM ATP and 0.1 μCi of 33P-ATP. Kinase reactions are incubated for 1 hour at room temperature and are stopped by the addition of 0.1% Triton X-100, 1 mM ATP, 5 mM EDTA, and 5 mg/mL streptavidin-coated SPA beads. SPA beads are captured using a 96-well GF/B filter plate and a Filtermate universal harvester. Beads are washed twice with 2 M NaCl and twice with 2 M NaCl containing 1% phosphoric acid. The signal is then assayed using a TopCount 96-well liquid scintillation counter. Dose-response curves are generated from duplicate, eight-point serial dilutions of inhibitory compounds. IC50 values are derived by nonlinear regression analysis[1].

Cell Assay [1]
A2780 cells are plated onto tissue culture dishes and propagated with the appropriate growth media. Growing cultures are exposed to increasing concentrations of Dinaciclib (0.75, 1.5, 3.15, 6.25, 12.5, 25, and 500 nM) or a vehicle control, typically for 7 days. After removing the medium, cells are fixed with 50% methanol/50% acetone for 5 minutes and stained with 0.2% crystal violet in 2% ethanol for 5 minutes. Following staining, cells are washed with 5 to 10 mL of water. Stained cells are solubilized in 1% deoxycholic acid, and the absorbance of the resulting solution is measured at 600 nm using a SOFTmax PRO 4.3 plate reader. Absorbance of Dinaciclib-treated samples is plotted as a percent of that of a vehicle-treated control, and data are reported as an IC50 value relative to these controls. For suspension cell lines, assessments of cell viability are obtained using the alamarBlue Cell Viability Assay kit[1].

Animal Administration [1]
Mice[1] For tumor implantation, specific cell lines are grown in vitro, washed once with PBS, and resuspended in 50% Matrigel in PBS to a final concentration of 4×107 to 5×107 cells per milliliter. Nude mice are injected with 0.1 mL of this suspension s.c. in the flank region. Tumor length (L), width (W), and height (H) are measured by a caliper twice weekly on each mouse and then used to calculate tumor volume using the formula (L×W×H)/2. When the tumor volume reaches 100 mm3, the animals are randomized to treatment groups (10 mice/group) and treated i.p. with either Dinaciclib (8, 16, 32, and 48 mg/kg daily, i.p.) or individual chemotherapeutic agents according to the dosing schedule indicated in table and figure legends. Tumor volumes and body weights are measured during and after the treatment periods.

Ezetimibe (SCH 58235) is a potent cholesterol absorption inhibitor. Ezetimibe is a Niemann-Pick C1-like1 (NPC1L1) inhibitor, and is a potent Nrf2 activator.
IC50 & Target
NPC1L1, Nrf2[1]
体外研究 (In Vitro)
Ezetimibe (Eze) acts as a potent Nrf2 activator without causing cytotoxicity. Ezetimibe enhances transactivation of Nrf2, as revealed by a luciferase reporter assay. Ezetimibe also upregulates Nrf2 target genes, including GSTA1, heme oxygenase-1 (HO-1) and Nqo-1 in Hepa1c1c7 and MEF cells. Ezetimibe upregulates Nrf2 target genes in Nrf2+/+ MEF cells, whereas this induction is totally blocked in Nrf2-/- MEF cells. Taken together, Ezetimibe acts as a novel Nrf2 inducer in a ROS-independent manner[1]. Human huh7 hepatocytes are pretreated with Ezetimibe (10 μM, 1 h) and incubated with palmitic acid (PA, 0.5 mM, 24 h) to induce hepatic steatosis. Ezetimibe treatment significantly attenuates PA-increased triglycerides (TG) levels, which is consistent with our animal study. PA treatment resulted in an approximately 20% decrease in mRNA expression of ATG5, ATG6, and ATG7, which had been increased by Ezetimibe treatment. In addition, Ezetimibe treatment significantly increased the PA-induced reduction in LC3 protein abundance[2].

体内研究 (In Vivo)
Administration of Ezetimibe (Eze) reduces the liver weights of mice fed the methionine- and choline-deficient (MCD) diet. This is consistent with the beneficial effects of Ezetimibe on hepatic steatosis. Liver histology shows pronounced multiple macrovesicular fat droplets in mice on the MCD diet, but Ezetimibe treatment markedly decreases the number and size of those droplets. Furthermore, hepatic fibrosis in mice fed the MCD diet is significantly attenuated by Ezetimibe[1]. Blood and liver lipid levels including TG, free fatty acids (FFA), and total cholesterol (TC) are significantly decreased in Ezetimibe-treated OLETF rats. Moreover, OLETF rats show higher serum levels of glucose, insulin, HOMA-IR, TG, FFA, and TC than LETF animals, which are significantly reduced by Ezetimibe. In addition, histological analysis indicated that OLETF control rats showed larger lipid droplets in hepatocytes than age-matched LETO controls, which are attenuated by administration of Ezetimibe[2].

Kinase Assay [1]
GST-p62 is prepared from Escherichia coli and 0.5 μg of the purified GST-p62 protein is used for in vitro AMPK phosphorylation assay. Phosphorylation of p62 protein by AMPK is determined by non-radioisotope method using γS-ATP. AMPK complex is immuno-purified from the HEK293 cells, to which either myc-AMPKα1 wild-type (WT) or myc-AMPKα1 kinase-dead mutant (KD, D157A) is transfected with Flag-AMPKβ1 and HA-AMPKγ1. AMPK complex is added into the reaction mixture containing 20 mM HEPES, pH7.4, 1 mM EGTA, 0.4 mM EDTA, 5 mM MgCl2, 0.05 mM DTT, 0.5 μg GST-p62, 0.2 mM AMP, and 1 mM ATPγS. Reaction is carried out at 37°C for 30 min, and then terminated by adding 20 mM EDTA. To detect γS-labeled p62 protein, the reaction product is alkylated with 2.5 mM PNBM for 2 h at room temperature and analyzed the products by western blotting using anti-thiophosphate antibody[1].

Animal Administration [1][2]
Mice[1] Ten-week-old C57BL/6J male mice are used. These animals are randomly assigned to one of three groups (7-10 mice in each group): normal chow diet; MCD diet, vehicle-treated; or MCD diet, Ezetimibe -treated. The mice had free access to diet and water, with temperature maintained at 23±2°C, humidity of 60%±10%, and 12-h light/dark cycles. In the MCD diet with Ezetimibe group, Ezetimibe 10 mg/kg is given once daily by oral gavage for 4 weeks. The chow and MCD diet with vehicle groups received the same volume of phosphate buffered saline orally for 4 weeks. Body weight is measured once a week over the course of the treatment period. After 4 weeks, the mice are anesthetized and killed; blood is collected via heart puncture. Tissues are harvested and either snap-frozen in liquid nitrogen and stored at −70°C or fixed in formalin and embedded in paraffin. Rats[2] Male OLETF (n=11) and age-matched LETO rats (n=3) are used, and experiments are conducted in a specific pathogen-free facility with a 12 h light/dark cycle. The OLETF rat is a model that represents late-onset hyperglycemia and exhibits a chronic disease course, mild obesity and clinical onset of diabetes mellitus. Animals have unrestricted access to water and food. At 12 wk of age, rats are randomized and treated with either PBS or Ezetimibe (10 mg/kg per day) via a stomach gavage for 20 wk. At the end of the study, the rats are fasted overnight and anesthetized with intraperitoneal Zoletil/Rompun. Blood is collected from the abdominal aorta, and liver tissues are dissected, immediately frozen in liquid nitrogen, and stored at -80°C until further analysis.

Lonafarnib (Sch66336) is a potent and orally active farnesyl transferase (FTase) inhibitor. Lonafarnib inhibits the activities of H-ras, K-ras and N-ras with IC50 values of 1.9 nM, 5.2 nM and 2.8 nM, respectively. Lonafarnib also has anti-hepatitis delta virus (HDV) activities.
Lonafarnib (Sch66336) potently inhibits Ha-Ras processing in whole cells and blocks the trans formed growth properties of fibroblasts and human tumor cell lines expressing activated Ki-Ras proteins[1]. All treatment groups containing Lonafarnib (10 µM) show a significantly higher level of unfarnesylated H-Ras (116-137%) compared to control treatment[2].

体内研究 (In Vivo)
In mouse, rat, and monkey systems, Lonafarnib (Sch66336) has excellent oral bioavailability and pharmacokinetic properties. In the nude mouse, Lonafarnib demonstrates potent oral activity in a wide array of human tumor xenograft models including tumors of colon, lung, pancreas, prostate, and urinary bladder origin[1]. Lonafarnib alone (80 mg/kg by oral gavage, once daily) has limited ability to inhibit orthotopic U87 tumors compared to vehicle treated control animals (T/C of 0.67). The combination of XRT/Tem (2.5Gy/day for 2 days; 5 mg/kg by oral gavage 90 min prior to XRT) is designed to produce modest tumor growth inhibition in vivo(T/C of 0.42). Concurrent Lonafarnib/XRT/Tem (Lonafarnib 80 mg/kg by oral gavage, once daily, XRT 2.5Gy/day for 2 days, and Tem 5 mg/kg by oral gavage 90 min prior to XRT) provides the strongest growth reduction (T/C of 0.02) and is significantly more effective than XRT/Tem (p<0.04), with the majority of animals demonstrating a decrease in tumor volume (p<0.05) after two weeks and persisting after 4 weeks (p<0.05)[2].

Cell Assay [2]
CellTiter96 Aqueous Assay kit is used. Assays are performed with 5000 cells/well in a 96-well tissue culture plate. Plates are irradiated 24 h after drug exposure and assayed 96 h after XRT, with fresh drug treatments applied each day. For quantification, dye is added directly to each well, plates are washed as per the manufactures recommendation and cell viability determined by optical density. Significance is analyzed using the Student’s T-test. 12-well plates are seeded with 100,000 cells/well. Drug treatments are initiated 24 h after plating, and media is replaced every 24 h for a total of 96 h of drug exposure. Plates are irradiated after 24 h of drug exposure. Cells from triplicate sets of treatments are trypsonized and counted 48 h after irradation using a Z1 series coulter counter, and compared to cell numbers from wells counted on Day 1 (the day drug treatment is initiated). Proliferation after drug treatments are normalized to the control wells and expressed as % of the control treatment. Significance is analyzed using the Student’s T-test[2].

Animal Administration [2]
Mice[2] Lonafarnib is given once daily at 80mg/kg with twice weekly weightings to ensure accurate dosing. Temozolomide (Tem) is given by gavage at 5 mg/kg 90 min prior to XRT. For irradiation, anesthetized mice are placed in a lead shielding apparatus which limited radiation exposure to the head only. Treatment (2.5Gy/day for two days) is delivered using a Gammacell 40 irradiator delivering 100 rads/min. For in vivo combination experiments, suboptimal doses of XRT/Tem are selected to permit identification of synergistic effects of Lonafarnib.

A combination of flutamide and LHRH agonist induces an additive effect with a decrease in prostate weight to 101 mg, and an marked drop in prostatic ODC activity [4].

体外研究 (In Vitro)
SCH900776 (300 nM) shows potent inhibitory activities against phosphorylation at ser296-Chk1. SCH900776 (1 μM) causes a 30-fold decrease in the IC50 for NSC-32065 in MDA-MB-231 cells[1]. The Kd value of SCH 900776 for the CHK1 kinase domain is 2 nM. SCH 900776 exhibits an approximate EC50 of 60 nM in cells exposure to NSC-32065. SCH 900776 induces dose-dependent suppression of CHK1 pS296 and concomitant accumulation of phospho-RPA signal in U2OS cells[2].

体内研究 (In Vivo)
SCH 900776 induces the γ-H2AX biomarker at 4 mg/kg (i.p.), and enhances tumor pharmacodynamic and regression responses in A2780 xenograft model. SCH 900776 (16 and 32 mg/kg, i.p.) induces incremental improvements in tumor response. Escalation of SCH 900776 dose to 20 and 50 mg/kg in combination with LY 188011 results in improvements in TTP 10× in the A2780 xenograft systems[2].

Kinase Assay [2]
The Kinase Profiler service is used to generate general selectivity data for SCH 900776 against a broad range of serine/threonine and tyrosine kinases. Assays are typically run at two concentrations of SCH 900776 (0.5 and 5 μM), at a fixed (10 μM) concentration of ATP.

Cell Assay [1]
For cell growth assays, cells are seeded at low density (500-1000 cells) in 96-well plates and then incubated with drug for 24 h (8 wells per concentration). Following treatment, cells are washed and grown in fresh media for 5-7 days at 37°C. Prior to attaining confluence, cells are washed, lysed, and stained with Hoechst 33258. Fluorescence is read on a microplate spectrofluorometer. Results are expressed as mean and standard error for the concentration of drug that inhibited growth by 50%.

Animal Administration [2]
For tumor implantation, specific cell lines are grown in vitro, washed once with PBS and resuspended in 50% Matrigel in PBS to a final concentration of 4×107 to 5×107 cells per mL. Nude mice are injected with 0.1 mL of this suspension subcutaneously in the flank region. Tumor length (L), width (W), and height (H) are measured by a caliper twice a week on each mouse and then used to calculate tumor volume using the formula: (L×W×H)/2. Animals (N=10) are randomized to treatment groups and treated intraperitoneally with either SCH 900776 (formulated in 20% hydroxypropyl β-cyclodextrin) or individual chemotherapeutic agents, formulated as recommended. Tumor volumes and body weights are measured during and after the treatment periods. Data are recorded as means±SEM before being normalized to starting volume. Time to progression to 10x starting volume (TTP 10x) is monitored in some experiments. For pharmacodynamic marker analyses in mice, tumors and adjacent skin are collected at necropsy, fixed overnight in 10% formalin, and washed/stored in 70% ethanol. For skin punch biopsies, an area of approximately 4 square inches is shaved. Rats are anesthetized using inhaled isofluorane and dogs are locally anesthetized using subcutaneous administration of lidocaine. Samples are collected using a 4 mm biopsy punch. Skin punches are fixed in 10% formalin overnight before washing/storage in 70% ethanol.
