体外研究 |
Clemizole hydrochloride is found to inhibit HCV RNA replication in cell culture that is mediated by its suppression of NS4B’s RNA binding,with little toxicity for the host cell.The EC50 of Clemizole on the W55R mutant J6/JFH RNA is ~18µM (2.25 times the EC50 of the wild-type RNA).Clemizole is a novel inhibitor of TRPC5 channels.Clemizole efficiently blocks TRPC5 currents and Ca2+ entry in the low micromolar range (IC50=1.0-1.3µM).Clemizole exhibits a six-fold selectivity for TRPC5 over TRPC4β (IC50=6.4µM),the closest structural relative of TRPC5,and an almost 10-fold selectivity over TRPC3 (IC50=9.1µM) and TRPC6 (IC50=11.3µM).Clemizole hydrochloride as a novel blocker of TRPC5 with a half-maximal inhibitory oncentration of 1.1µM.The concentration-response curves confirmed a concentration dependent block of TRPC5 by Clemizole and revealed an apparent IC50 of 1.1±0.04µM. |

体内研究 |
Clemizole hydrochloride has an unexpectedly short plasma half-life (measured at 0.15 hours);it is very rapidly biotransformed into a glucuronide (M14) and a dealkylated metabolite (M12) and into a variety of lesser metabolites in C57BL/6J mice. |

细胞实验: |

Huh7.5 cells are maintained in DMEM supplemented with 1% L-glutamine,1% penicillin,1% streptomycin,1×nonessential amino acids and 10% FBS.Cell lines are passaged twice weekly after treatment with 0.05% trypsin-0.02% EDTA and seeding at a dilution of 1:5.Subconfluent Huh7.5 cells are trypsinized and collected by centrifugation at 700g for 5 min.The cells are then washed three times in ice-cold RNase-free PBS and resuspended at 1.5×107 cells/mL in PBS.Wild-type or mutant FLJ6/JFH-5′C19Rluc2AUbi RNA for electroporation is generated by transcription of XbaI linearized DNA templates using the T7 MEGAscript kit,followed by purification (RNA transcription and fluorescent labeling).We mixed 5µg of RNA with 400µL of washed Huh7.5 cells in a 2-mm-gap cuvette (BTX) and immediately pulsed (0.82 kV,five 99µs pulses) with a BTX-830 electroporator.After a 10 min recovery at 25℃,pulsed cells are diluted into 10mL of prewarmed growth medium.Cells from several electroporations are pooled to a common stock and seeded in 6-well plates (5×105 cells per well).After 24h,medium is replaced and cells are grown in the presence of serial dilutions of the various inhibitory compounds (e.g.,Clemizole hydrochloride) identified in the screen.Seventeen commercially available compounds,out of the 18 identified,are analyzed.Untreated cells are used as a negative control for water-soluble compounds.For compounds (e.g.,Clemizole hydrochloride) solubilized in DMSO,untreated cells are grown in the presence of corresponding concentrations of the solvent as a negative control.Medium is changed daily.After 72h of treatment cells are subjected to an Alamar Blue-based viability assay and luciferase assay.After 72h of treatment cells are incubated for 3h at 37℃ in the presence of 10% Alamar Blue reagent.Plates are then scanned and fluorescence is detected by using FLEXstation II 384.Depending on the inhibitory compound’s solvent (e.g.,Clemizole hydrochloride),water or DMSO,signal is normalized relatively to untreated samples or samples grown in the presence of DMSO,respectively. |

Mice Eight control NOG mice and eight humanized TK-NOG mice are administered 25mg/kg by mouth Clemizole,and blood samples are collected 30 minutes after administration.The C57BL/6J mice (3 per time point) are given 25mg/kg by mouth clemizole,and blood samples are collected for analysis at 15 and 30 minutes and 1,2,4,and 6 hours after administration.For the DDI studies,eight humanized TK-NOG mice are given Clemizole (25mg/kg by mouth) with or without Ritonavir (20mg/kg by mouth),and blood samples are collected 30 minutes after administration.Six of these mice are also treated with Debrisoquine (10mg/kg by mouth) in the presence or absence of Ritonavir (20mg/kg by mouth),and plasma samples are obtained 2 hours later for analysis. |
