体外研究

Aprepitant decreases the metabolic activity with an estimated IC50 value of 20µM.Aprepitant induces cell-growth inhibition and G1 cell-cycle arrest.Aprepitant significantly induces apoptosis in Nalm-6 cells,and the apoptosis is mediated through caspase-3 activation.Aprepitant (20µM) induces p53 accumulation and expression of pro-apoptotic p53 target genes.Aprepitant (1,5,10µM) inhibits HIV infection in MDM from both depressed and not depressed HIV negative individuals ex vivo in a dose-dependent manner.IC90 value of aprepitant is equivalent to 10μM,and the IC50 value is about 5μM.

体内研究

Aprepitant prevents the increase of NK-1R expression induced by in vivo NHP infection with B.burgdorferi.Aprepitant treatment prevents B.burgdorferi-induced increases in CCL2 protein levels in the CSF of NHPs.Aprepitant treatment prevents B.burgdorferi-induced increases in CCL2 and CXCL13 mRNA expression in the dorsal root ganglia of NHPs,prevents B.burgdorferi-induced increases in CCL2,CXCL13,IL-17A,and IL-6 mRNA expression in the spinal cord of NHPs.Aprepitant treatment attenuates B.burgdorferi infection-induced reductions in astrocyte activity/numbers.Aprepitant (10mg/kg,i.p.) significantly attenuates the CPP expression and locomotor activation produced by AMPH and cocaine in mice.In contrast,aprepitant significantly enhances the expression of CPP produced by morphine while significantly suppressing the locomotor activity of the mice conditioned with morphine.Aprepitant does not induce significant CPP or conditioned place aversion or locomotor activation or suppression.Aprepitant (125mg/day,p.o.) results in 1 log reduction in plasma levels of viral RNA as compared to non-treated controls.

 

推荐实验方法(仅供参考)

细胞实验:

 

The inhibitory effect of aprepitant on metabolic activity of Nalm-6 cells is assessed by uptake of thiazolyl blue tetrazolium bromide (MTT) by viable cells.Cells are plated onto 96-well plates at a density of 5000 cells/well.After treatment with aprepitant at 5,10,15,20 and 30µM for 24,36 and 48h,the cells are further incubated with 100μL of MTT (0.5mg/mL) at 37℃ for 3h.Untreated cells are defined as the control group.Following solubilization of precipitated formazan with 100μL of DMSO,the optical densitometry is measured with an ELISA reader at a wavelength of 578nm.

 

动物实验:

 

Fifteen rhesus macaques are anesthetized and inoculated intrathecally with 1×108

live spirochetes into the cisterna magna,whereas five rhesus macaques are left uninfected and receive 1mL of RPMI 1640 medium after removing an equivalent volume of CSF.The establishment of in vivo B.burgdorferi infection is confirmed by positive culture from at least necropsy tissue sample.The first set of animals are studied for 2 weeks and included two control animals (one of which is treated with aprepitant),two infected and untreated animals,and two infected animals that are treated with aprepitant.The second set of animals are studied for 4 weeks and included three control animals (one of which is treated with aprepitant),five infected and untreated animals,and four infected animals treated with aprepitant.Animals receive an average dose of aprepitant of 28±6mg/kg per day p.o.daily,and drug treatments are started 2 days before inoculation.These doses are consistent with standard veterinary regimens for the chosen drugs in NHP,and the 4-week duration of the study precludes the development of neural pathology that occurs at 8 weeks following B.burgdorferi infection.
