In continuation of our efforts toward the discovery of potent HIV-1 NNRTIs with diverse structures, a series of novel S-DACO analogues of 6-(2-cyclohexyl-1-alkyl)-2-(2-oxo-2-phenyl-ethylsulfanyl)pyrimidin-4(3H)-ones were designed, synthesized and evaluated for their antiviral activities in MT-4 cells. Most of these new compounds showed moderate to good activities against wild type HIV-1 with IC50 values ranging from 7.55 μmol/L to 0.018 μmol/L. Among them, compound 5c was identified as the most promising inhibitor against HIV-1 replication with an IC50 = 0.018 μmol/L, CC50 = 194 μmol/L, and SI = 12791, which was much more potent than the reference drugs NVP and DLV and comparable to AZT and EFV. In addition, 5c also exhibited improved activity against double mutant HIV-1 strain RES056 compared to that of the reference drugs NVP/DLV and DB02. The preliminary structure-activity relationship (SAR) and molecular modeling studies were also discussed, which provides some useful indications for guiding the further rational design of new S-DACO analogues.

Paragraph 0028-0033; 0042, (2020/08/25)
The invention belongs to the field of organic synthesis, and particularly relates to a synthetic method of an acid compound. An acid anhydride compound and an alkyl bromide or a functionalized alkyl bromide are subjected to a cross-electrophilic coupling reaction to synthesize an acid compound, so that the application of the alkyl bromide in the cross-electrophilic coupling reaction is expanded, and a novel non-traditional method for chemically and selectively constructing a carbon-carbon bond through a decarburization process is provided. The synthesis method is simple, economic, green and environment-friendly, and has wider applicability or is suitable for large-scale production.

Paragraph 0016, (2020/10/14)
The invention provides a preparation method for synthesizing propiolic acid and derivatives thereof. The synthetic route of the method comprises the following steps: firstly, under anhydrous and anaerobic conditions, adding magnesium metal, elemental iodine and a solvent into a reactor, uniformly stirring the reactants, and then dropwise adding halogenated hydrocarbon to react to generate a hydrocarbyl magnesium halide Grignard reagent; dropwise adding terminal alkyne into the reactor for Grignard exchange reaction to obtain alkynyl magnesium halide; and finally, introducing CO2 into the reactor, carrying out nucleophilic addition reaction, and hydrolyzing the product to obtain the propiolic acid compound. The preparation method provided by the invention is simple, safe and mild in operation condition.
