Antimicrobial resistance crisis: could artificial intelligence be the solution?

Antimicrobial resistance is a global public health threat, and the World Health Organization (WHO) has announced a priority list of the most threatening pathogens against which novel antibiotics need to be developed. The discovery and introduction of novel antibiotics are time-consuming and expensive. According to WHO's report of antibacterial agents in clinical development, only 18 novel antibiotics have been approved since 2014.

[Chemical constituents from Coptis chinensis].

Objective: To study the chemical constituents of Coptis chinensis.

Methods: The compounds were separated and purified by column chromatography and their structures were identified by spectroscopic methods.

Results: Seven compounds were isolated from the chloroform extract of Coptis chinensis, whose structures were determined as worenine (1),8,9-dihydroxy-1,5,6, 10b-tetrahydro-2H-pyrrolo[2,1 -alpha] isoquinolin-3-one (2),(+/-) -5,5'-dimethoxy-lariciresinol (3),3,4-dihydroxy-phenylethylalcohol(4), methyl-5-O-feruloylquinate (5), ethyl-5-O- feruloylquinate (6), apocynol (7).

[Determination of V, Mo, Ni, g in Chinese traditional cardiovascular medicine by AAS].

Aimed at curing life-threatening cardiovascular diseases, many new drugs containing Chinese medicines have been developed for commercial use. It is critical that the contents of these drugs are well monitored and controlled. In the last five decades, understanding the effects of trace elements on treating cardiovascular diseases has drawn more and more attention of researchers.

[Study on trace elements in wuji baifeng wan and its preparation].

We studied the amount of trace elements in the traditional Chinese medicine Wuji Baifeng Wan by cluster analysis, and found that the clustering results of the trace elements in Twelve Wuji Baifeng Wan (the southern preparation) and Wuji Baifeng Wan (the northern preparation) were not in the same group. In this paper, AAS was used for the determination of trace elements in Wuji Baifeng Wan and its preparation. The results showed that there were great differences between Twelve Wuji Baifeng Wan and Wuji Baifeng Wan , while the difference between Chinese Taihe Chicken and Native Chicken was slight.
