-
Paragraph 0089-0093, (2021/09/01)
The invention relates to N4 - hydroxycytidine derivatives as shown in general formula I. A pharmaceutically acceptable salt, a tautomer thereof, a stereoisomer thereof, a metabolite thereof, a metabolic precursor thereof, or a prodrug thereof, and the substituted N4 - hydroxycytidine derivative structure of the structure of Formula I. The pharmaceutical composition is used for preparing medicaments for treating infections such as SARS-CoV, HBV, HCV, H1N1, Ebola and SARS-CoV - 2, can effectively inhibit influenza viruses and SARS-CoV - 2 viruses, and can have the same result on other RNA viruses. The series of compounds can be applied to preparation of anti RNA virus drugs. The medicine is used for preparing a medicine for treating virus infection and is used for preparing a vaccine adjuvant for treating virus infection.

-
Paragraph 0080-0084, (2021/12/07)
The present invention provides an N4- hydroxycytidine derivative as shown in formula I, a pharmaceutically acceptable salt thereof, a tautomer thereof, a stereoisomer thereof, a metabolite thereof, a metabolic precursor thereof, or a prodrug thereof: 。 The compounds of the present invention have the following significant advantages: (1) the N4-hydroxycytidine compounds and their derivatives have a highly efficient inhibitory activity of RNA-dependent RNA polymerases of RNA viruses; (2) the N4-hydroxycytoside compounds and their derivatives and pharmaceutical compositions are widely used, can be prepared to treat / prevent SARS-CoV, HBV, HCV, H1N1, Ebola or SARS-CoV-2 virus infection disease drugs.
Containing polyoxyethylene ether hydroxy propyl aniline [...] permanaganate betaine and its preparation method
-
Paragraph 0027; 0029, (2017/05/16)
The invention relates to polyoxyethylene-ether-containing hydroxypropyl anilino carboxylate betaine and a preparation method thereof, and mainly solves the problems in the prior art that an oil-displacement agent containing a surfactant is bad in oil displacement effect and high in use concentration under the oil reservoir conditions of high temperature and high salinity, and alkalis in alkali-surfactant-polymer flooding pollute and damage stratum and oil wells and severely corrode equipment and conveying pipelines. The polyoxyethylene-ether-containing hydroxypropyl anilino carboxylate betaine has the molecular general formula (I) shown in the specification, and in the formula (I), R1 is any one of C15-C39 alkyl and alkenyl, n is 1-10, R2 is any one of C1-C4 alkylidene and hydroxyl-substituted alkylidene. The technical scheme relatively well solves the problems and is applicable to tertiary oil recovery of oil fields.
