| Description | Morphothiadin (GLS4) is a potent inhibitor on the replication of both wild-type and adefovir-resistant HBV (IC50 of 12 nM). |
| In vitro | Morphothiadin是一种对野生型和具有adefovir抗性的HBV复制强效的抑制剂(半抑制浓度IC50为12 nM)。Morphothiadin(GLS4)在25 μM浓度下不表现出任何毒性。其对初代肝细胞的半数致死浓度(CC50)为115 μM(P<0.001),而在HepAD38细胞中的CC90为190 μM(P<0.01)。Morphothiadin在25 nM至100 nM的浓度范围内显著抑制了HepAD38细胞上清液中病毒的积累(P<0.02)[2]。 |
| In vivo | 在小鼠体内,每天给予3.75 mg/kg的Morphothiadin治疗后病毒滴度增加了83.5倍,给予7.5 mg/kg的治疗增加了28.3倍,但对于给予更高剂量Morphothiadin的小鼠来说增幅仅为3至6倍。通常Morphothiadin剂量与病毒滴度呈反比关系,其中给予3.75 mg/kg剂量的小鼠病毒滴度反弹最高(540倍),而给予60 mg/kg剂量的小鼠反弹最低(23倍)(P<0.001)。超过7.5 mg/kg每天的Morphothiadin剂量在整个治疗期内显著抑制病毒复制周期,而超过15 mg/kg每天的剂量可在治疗结束后至多维持2周的病毒抑制[2]。 |
