Paragraph 0073-0078, (2020/05/01)
The invention discloses a tenofovir phenyl propionate phosphoramidate compound as well as a pharmaceutical composition and an application of the tenofovir phenyl propionate phosphoramidate compound. The tests prove that the compound has the activity of inhibiting HBV virus replication, and has the advantages of higher activity, lower toxicity and the like than the existing drug tenofovir disoproxil fumarate (TDF) for treating AIDS. The experiments also prove that the compound also has the activity of inhibiting HIV-1 virus replication, and can be used for developing medicines for treating AIDSor medicines for treating hepatitis B.

The present invention discloses a tenofovir disoproxil fumarate analog preparation method, which comprises: carrying out a substitution reaction on adenine as a raw material and (R)-propylene carbonate in the presence of an alkali, carrying out a substitution reaction with (diethoxyphosphoryl)methyl-4-methylbenzenesulfonate, hydrolyzing with a concentrated hydrochloric acid solution, crystallizingto obtain anhydrous tenofovir, carrying out a reaction on the anhydrous tenofovir and chloromethyl isopropyl carbonate to obtain tenofovir monoester, and carrying out a reaction with 2-bromopropane to obtain the target compound. According to the present invention, the selected starting raw materials are inexpensive and easy to obtain, the process is simple, and the material utilization rate and total yield are improved; and the intermediate of the method is purified by re-crystallization, such that the yield is high, and the purity is high.
