Paragraph 0025-0027; 0044-0046; 0063-0065, (2020/11/22)
The invention belongs to the technical field of organic synthesis, particularly relates to a thiazole derivative and a synthetic method thereof, and particularly relates to a thiazole derivative (Z)-4-((2-(2-(2-(2,5-dimethoxyphenyl)-thiazole-5-yl)-ethylimino)(phenyl)methyl)-1,3-benzenediol and a synthetic method thereof. The synthesis method provided by the invention comprises the following steps:by taking 2,5-dimethoxybenzamide and ethyl 2-chloroacetate as raw materials, carrying out six reaction steps of carbonyl sulfide reaction, substitution, cyclization, substitution, chlorination, cyanidation, amidation, hydrolysis and substitution reaction to prepare the (Z)-4-((2-(2-(2-(2,5-dimethoxyphenyl)-thiazole-5-yl)-ethylimino)(phenyl)methyl)-1,3-benzenediol. According to the invention, an efficient synthesis method is provided for the synthesis of the thiazole derivative.

Small molecules with oxathiazol-2-one moiety were recently reported as potent inhibitors of Mycobacterium bovis var. bacilli Calmette-Guérin (BCG), among which HT1171 was the most potent and selective proteasome inhibitor. Herein we synthesized a series of novel compounds by bioisosteric replacement of the oxathiazol-2-one ring with 3H-1,2,4-dithiazol-3-one, and also fifteen 1,3,4-oxathiazol-2-one molecules in order for potency comparison and structure-activity relationship elucidation since their antibacterial effects on the virulent strains were not evaluated before. All the compounds were assessed for antitubercular activities on the virulent H37Rv strain by a serial dilution method. Among the tested compounds, 3H-1,2,4-dithiazol-3-one compound 4n was found to be the most active with a lowest MIC90 value of 1 μg/mL. Furthermore, the cytotoxicities of all the compounds against normal human liver cell line L02 were determined by an MTT method. Compound 4n displayed a lower inhibitory ratio than HT1171 at the concentration of 100 μM, indicating its better safety profile.
