Embodiment 1
[0037] Embodiment 1 synthesis of diaryl pyrimidine derivatives
[0038]Under the protection of an inert gas, add the substituted naphthol to an anhydrous aprotic solvent, stir to dissolve it, then add 4-chloropyrimidine derivatives, stir to dissolve it, add anhydrous K 2 CO 3 , control the temperature at 90-100°C, and stir for 8-12 hours. After TLC showed that the reaction was finished, the K 2 CO 3 , the filtrate was poured into cold water, the precipitated solid was filtered and dried. Decolorized by activated carbon and recrystallized from toluene to obtain the desired compound.
[0039] Different 4-chloropyrimidine derivatives and different substituted naphthols were used to obtain the target compounds by the above method, and some results are as follows:
[0040] in N 2 Under protection, 8-hydroxyquinoline (4.2mmol) was added to 30mL of anhydrous DMF, stirred to dissolve it, and then 2-(4-cyanoanilino)-4-chloro-5-methylpyrimidine (3.5 mmol), stirred for 10min to di...
Embodiment 2
[0058] Embodiment 2 anti-HIV biological activity test
[0059] The anti-HIV virus activity at the cell level in vitro was determined by the Rega Institute of Pharmacy at Katholleke University in Belgium, mainly including two aspects: inhibitory activity and cytotoxicity to HIV-infected MT-4 cells. The method is described as follows: make the compound in HIV-infected MT-4 cells, at different times of HIV infection, use the MTT method to measure the protective effect of the drug on the cytopathic changes induced by HIV, and calculate that 50% of the cells are free from HIV-induced cell changes. half effective concentration EC 50 , Toxicity determination is carried out in parallel with anti-HIV activity experiment, also in MT-4 cell culture, the concentration that makes 50% uninfected cells take place cytopathic (CC 50 ), and calculate the selectivity index SI=CC 50 / EC 50 .
[0060] The anti-HIV activity of each compound is monitored by the inhibitory effect of the drug on t...
