Product Information

Product Description

Biological Activity

Description Cidofovir suppresses virus replication by selective inhibition of viral DNA synthesis.
In vitro Cidofovir inhibits human cytomegalovirus (HCMV) infection in cultured cells. Cidofovir is inhibitory to CMV plaque formation even when added to the cells at 48 hr post infection with IC50 of 0.9 μg/mL for Davis and 1.6 μg/mL for AD-169 strains,respectively. [1] Cidofovir also inhibits herpes simplex virus infection. In addition, Cidofovir blocks cell fusion induced by HSV-1 in monkey kidney cells and blocks the expression of HSV-l-specific proteins and the synthesis of viral DNA. [3]
In vivo Cidofovir (5 mg/kg/day) subcutaneously for 5 days significantly reduces average virus infectivity titer in blood, spleen, lung and salivary gland in infected guinea pigs. Cidofovir significantly reduces lymphocytosis and average tissue indexe of spleen in infected animals. [2]. Cidofovir suppresses all manifestations (skin lesions, paralysis of the hind legs, and mortality) of hairless mice infected intracutaneously with HSV-1 or HSV-2. The most remarkable feature of Cidofovir is that a single administration of the compound, even as late as 4 days after infection, conferees significant protection against HSV-1 or HSV-2 infection. [4] Cidofovir inhibits growth of the highly aggressive melanoma tumor arising from mouse melanoma B16 cells grafted subcutaneously in C57B16/J mice. [5]

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.

Rat dose (mg/kg) = mouse dose (22.4 mg/kg) ×  mouse Km(3)  = 11.2 mg/kg
