-
Paragraph 0049; 0050, (2019/10/01)
The invention provides a dithiocarbamate-containing benzotriazole derivative and a preparation method and application thereof. Under the alkaline condition, dialkyl amine reacts with carbon disulfideto obtain dithiocarbamate salt, benzotriazole reacts with chloropropanol to obtain 3-(1-benzotriazolyl)propyl-1-alcohol, then 3-(1-benzotriazolyl)propyl-1-alcohol reacts with chloroacetyl chloride toobtain 3-(1-benzotriazolyl) propyl-2-chloroacetate, and finally 3-(1-benzotriazolyl)propyl-2-chloroacetate reacts with the dithiocarbamate salt to obtain the dithiocarbamate-containing benzotriazole derivative as shown in the general formula I. Accordingly, the preparation method is simple, the process condition is mild, raw materials are easy to obtain, the synthesis cost is low, the synthesis yield is high, environmental friendliness is achieved, the product can serve as an extreme pressure, anti-wear, anti-friction and anti-corrosion additive of lubricating oil to use, the bearing capacityof base oil can be obviously improved, and the anti-wear and anti-friction properties are improved.

The activity of β-lactam antibiotics is compromised by metallo-β-lactamases (MBLs). Herein, a series of dithiocarbamate derivatives were designed and synthesized. Their antibacterial activities were tested in combination with meropenem (MEM) against several MBL (NDM and IMP type)-producing clinical isolates. Clinical isolates harboring NDM-1 and IMP-4 became susceptible to MEM when it was combined with dithiocarbamate compounds 4a, 4b or 4f synthesized in this work. Compounds 4a and 4b increased the effectiveness of MEM by up to 2560 times against strains. In vitro bactericidal dynamics tests showed that bacteria died within 24 h when they were treated with compound 4f + MEM. Compounds 4a, 4b and 4f were non-hemolytic and exhibited low toxicity toward HeLa cells in vitro. These data show that compounds containing dithiocarbamate functional group may be helpful in the development of MBL inhibitors.
