, p. 180 - 186 (2017)
In the current study, bivalent compounds 1–17 constructed by covalently linking the ?-amino group of lysine in a tripeptidic scaffold to a functionality via a linker were prepared and examined for their inhibitory potencies against SIRT1, a prototypical member of the β-nicotinamide adenine dinucleotide (β-NAD+)-dependent sirtuin family of protein Nε-acyl-lysine deacylases. A few of them were found to be stronger SIRT1 inhibitors than the N?-acetyl-lysine-containing monovalent counterparts 18 and 19. As exemplified with compounds 6 and 18, a bivalent SIRT1 inhibitor could exhibit a greater degree of inhibitory selectivity among SIRT1/2/3 than the corresponding monovalent counterpart. This study has laid a foundation for the future development of superior bivalent inhibitors against the (patho)physiologically and therapeutically important sirtuin family of deacylase enzymes.

Paragraph 0072-0073, (2019/12/25)
The invention belongs to wastewater treatment and in particular discloses a method for utilizing a byproduct 2-sodium thioglycollate in the production process of thionocarbamate. The method comprisesthe following steps: by taking a byproduct 2-sodium thioglycollate in the production process of thionocarbamate as a raw material, enabling the byproduct to react with a halogenation reagent so as toobtain alkyl thioether acetic acid; performing esterification on the alkyl thioether acetic acid with methanol so as to obtain alkyl thioether methyl acetate; and further enabling the alkyl thioethermethyl acetate to react with hydroxylamine hydrochloride, so as to obtain alkyl thioether ethyl hydroximic acid. By adopting the method, the problem that the byproduct 2-sodium thioglycollate in a process of thionocarbamate is hard to recycle can be solved, the utilization rate of the byproduct is increased, and the environment can be protected.

Paragraph 0059-0061, (2018/02/04)
The application relates to design of a novel molecule with ester group substituted by sulfone group by using a caffeic acid phenethyl ester (CAPE) with neuroprotective activity extracted from natural propolis as a primer according to bioisosterism principle and hydrogen-bond interaction theory; and the molecule has a structural general formula I, and the definition of each group is shown in the claims. The invention also relates to compound in vitroantioxidation capability evaluation, neuroprotective activity evaluation on cell level and traverse blood brain barrier ability evaluation. Activity evaluation results show that the synthesized novel compound has enhanced neuroprotective activity and can easily traverse the blood brain barrier, thus becoming a novel neuroprotective agent for treating neurodegenerative diseases.
