Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

The present study is a continuation of the scientific research works for the synthesis of anthraquinonе-containing derivatives with cyclic ring systems by the interaction of 1,2,4-trihydroxyanthraquinone (purpurin) with cyclic carboxylic acid chlorides. Series of purpurin esters containing a saturated cyclic fragment was studied for antibacterial activity about museum strains of microorganisms. The effects of these preparations in vitro about Staphylococcus aureus ATCC 6538, Bacillus subtilis ATCC 6633, Escherichia coli ATCC 25922, Pseudomonas aeruginosa АТСС 27853 and fungus Сandida albicans АТСС 10231 were studied. It has been found that the compounds with the cyclohexane fragment have possess an antimicrobial activity with strains of microorganisms Staphylococcus aureus АТСС 6538 for which the MIC value was 31.25 μg/ml.
