用途: Cidofovir is an anti-CMV drug which can suppress CMV replication by selective inhibition of viral DNA polymerase and therefore prevention of viral replication and transcription.IC50 Value:Target: CMV DNA polymerasein vitro: The minimum concentrations of (S)-HPMPC required to inhibit CMV plaque formation by 50% was microgram/ml. The selectivity indices of (S)-HPMPC, as determined by the ratio of the 50% inhibitory concentration for cell growth to the 50% inhibitory concentration for plaque formation for CMV (AD-169 strain), was 1,500 [1]. The time course of uptake of HPMPC into Vero cells was linear between 10 and 75 min and proportional to the concentration in the medium from 10(-6) to 10(-2) M. HPMPC uptake was temperature sensitive and the rate of uptake was considerably lower at 27 degrees than at 37 degrees and almost totally inhibited at 4 degrees [2]. in vivo: Levels of cidofovirin serum following intravenous infusion were dose proportional over the dose range of 1.0 to 10.0 mg/kg of body weight and declined biexponentially with an overall mean +/- standard deviation terminal half-life of 2.6 +/- 1.2 h (n = 25). Approximately 90% of the intravenous dose was recovered unchanged in the urine in 24 h. The overall mean +/- standard deviation total clearance of the drug from serum (148 +/- 25 ml/h/kg; n = 25) approximated renal clearance (129 +/- 42 ml/h/kg; n = 25), which was significantly higher (P 作用: 作用机制是在细胞胸苷激酶的作用下转化为活性代谢物单磷酸酯、二磷酸酯及磷酸胆碱的加成物,这些活性物抑制DNA聚合酶,竞争性地抑制脱氧胞嘧啶核苷-5'-三磷酸酯整合人病毒的DNA,缓DNA成,并使病毒DNA去稳定性,从而抑制病毒复制.因本品活性形态受细胞酶而不是病毒酶的作用,故病毒的突变不会使本品产生耐药性.临床上本品用于治疗敏感病毒引起的感染,如CMV视网膜炎、AIDS患者黏膜及皮肤HSV-I型和HSV-II型感染、乳头状瘤病毒感染等。本品毒性小,但有一定肾毒性,与丙磺舒合用可降低其肾毒性。 物理化学性质: CAS号:113852-37-2 常用中文名:西多福韦 常用英文名:Cidofovir 分子式:C8H14N3O6P 分子量:279.187 密度:1.8±0.1 g/cm3 沸点:609.5±65.0 °C at 760 mmHg 熔点:260ºC 闪点:322.4±34.3 °C 储存条件:room temp |
