A series of novel 9, 13-disubstituted berberine derivatives have been synthesized and evaluated for the antibacterial activities against Staphylococcus aureus, including Newman strain and multidrug-resistant strains (NRS-1, NRS-70, NRS-100, NRS-108, and NRS-271). Compound 20 shows the most potent activity against the growth of Newman strain, with a MIC value of 0.78?μg/mL, which is comparable with the positive control vancomycin. In addition, compound 20, 21, and 33 are highly antistaphylococcal active against five strains of multidrug-resistant S.?aureus, with MIC values of 0.78–1.56?μg/mL. Of note, theses antibacterial active compounds have no obvious toxicity to the viability of human fibroblast (HAF) cells at the MIC concentration.

Histone modifying proteins, specifically histone deacetylases (HDACs) and bromodomains, have emerged as novel promising targets for anticancer therapy. In the current work, based on available crystal structures and docking studies, we designed dual inhibitors of both HDAC6/8 and the bromodomain and PHD finger containing protein 1 (BRPF1). Biochemical and biophysical tests showed that compounds 23a,b and 37 are nanomolar inhibitors of both target proteins. Detailed structure-activity relationships were deduced for the synthesized inhibitors which were supported by extensive docking and molecular dynamics studies. Cellular testing in acute myeloid leukemia (AML) cells showed only a weak effect, most probably because of the poor permeability of the inhibitors. We also aimed to analyse the target engagement and the cellular activity of the novel inhibitors by determining the protein acetylation levels in cells by western blotting (tubulin vs histone acetylation), and by assessing their effects on various cancer cell lines.

Paragraph 0020; 0023; 0025, (2018/11/03)
The invention belongs to the field of medicinal chemical industry, and particularly relates to a synthetic process of an esmolol intermediate 3-(4-hydroxyphenyl) methyl propionate. The synthetic process comprises the steps of: adopting p-methyl phenol and acetic anhydride as raw materials, performing an acylation reaction to obtain (4-methyl) phenol acetate, performing a halogenation reaction between the obtained (4-methyl) phenol acetate and a halogenating reagent, then carrying out a substitution reaction between the halogenated product and diethyl malonate, performing hydrolysis decarboxylation, and then carrying out an esterification reaction between the obtained product with methanol to obtain the 3-(4-hydroxyphenyl) methyl propionate. Through the route of the synthetic process, the process conditions are optimized, and the synthetic process has simple operation, easy and available raw materials and low cost; and the 3-(4-hydroxyphenyl) methyl propionate is obtained finally through acylation, halogenation, substitution, hydrolysis decarboxylation and the esterification reaction, and the synthetic process has a good industrial value and a total yield of 48.8%.
