A series of new O-(substituted benzyl) phosphoramidate prodrugs of tenofovir for the treatment of hepatitis B virus (HBV) infections have been designed and synthesized. An investigation of structure-activity relationships revealed that the compound bearing an o-methylbenzyl group (1a) has the most potent in vitro anti-HBV activity. This prodrug (1a) was well-tolerated in KM mice via intragastric administration at a dosage of up to 1.5 g/kg. In DHBV-infected ducks, prodrug 1a displayed a good inhibitory effect on the viral DNA replication in both the serum and the liver in a time- and dose-dependent manner and did not cause any necrosis, hemorrhage, or inflammatory response in the animal livers. Further investigation demonstrated that prodrug 1a achieved a higher exposure of the bioactive metabolite (tenofovir diphosphate, TFV-DP) in the liver, the target organ for the treatment of HBV infection, than tenofovir alafenamide fumarate (TAF) did at an equimolar dose. In the experiment, the researchers used many compounds, for example, (4-Methoxyphenyl)methanol (cas: 105-13-5Quality Control of (4-Methoxyphenyl)methanol).
(4-Methoxyphenyl)methanol (cas: 105-13-5) belongs to ethers. Of all the functional groups, ethers are the least reactive ones. Ether bonds are quite stable towards bases, oxidizing agents and reducing agents. At room temperature, ethers are pleasant-smelling colourless liquids. Relative to alcohols, ethers are generally less dense, are less soluble in water, and have lower boiling points. They are relatively unreactive, and as a result they are useful as solvents for fats, oils, waxes, perfumes, resins, dyes, gums, and hydrocarbons. Vapours of certain ethers are used as insecticides, miticides, and fumigants for soil.Quality Control of (4-Methoxyphenyl)methanol
