别名:Vistide; GS 0504; HPMPC
Cidofovir通过选择性抑制病毒DNA的合成而抑制病毒复制。Cidofovir处理培养的细胞,抑制人类巨细胞病毒(HCMV)感染。Cidofovir抑制巨细胞病毒(CMV)蚀斑形成,即使是感染后48小时后加入到细胞中,作用于Davis和AD-169株时IC50分别为0.9 μg/mL和1.6 μg/mL。 Cidofovir也抑制单纯疱疹病毒感染。

细胞系 | Madin–Darby Canine Kidney or Vero cells |
方法 | In vitro efficacy of cidofovir against CHV-1 Madin–Darby Canine Kidney or Vero cells were plated into 96-well plates at 1*104 cells/well and maintained in Dulbecco’s minimal essential medium with 1 g/L glucose, l-glutamine, and sodium pyruvate (Cell Grow; Corning, Manassas, VA) containing 10% fetal bovine serum (Atlanta Biological, Flowery Branch, GA) and penicillin (200 U/mL)/ streptomycin (200 mg/mL) (Life Technologies, Grand Island, NY) for 24 h until confluent. Monolayers were infected with 5 PFU/well CHV-1 (a previously described field strain that was also utilized during the in vivo experimental study evaluating cidofovir) or HSV-1 strain F, respectively. After 2 h of incubation at 37 C, virus supernatants were removed, cells were rinsed once with phosphate-buffered saline (PBS), and 100 mL of sequential 2-fold serial dilutions of cidofovir (starting at 625 mM) was added to each well. Infection controls without cidofovir and noninfected drug-treated controls were also included. Plates were incubated at 37 C until a cytopathic effect (CPE) was visible in the infected nontreated controls, which was *72 hours postinfection (hpi) for CHV-1 and 48 hpi for HSV-1, respectively. Plates were rinsed 3 times with PBS, fixed in 80% ethanol for 10 min at -20 C, and stained with crystal violet (Fisher Scientific, Fair Lawn, NJ). Virusinduced CPE was scored as the percent of wells per dilution with observable plaque formation, and EC50 values were calculated using GraphPad Prism. |

例如,依据体表面积折算法,将化合物用于小鼠的剂量20 mg/kg 换算成大鼠的剂量,需要将20 mg/kg 乘以小鼠的Km系数(3),再除以大鼠的Km系数(6),得到化合物用于大鼠的等效剂量为10 mg/kg。
