It has been connected with physiological processes in insects, human cells and bacteria. In this article, an overview of the biological importance of this compound is provided. A detailed analysis of its crystal structure and antibacterial properties were investigated. The experimental study was supplemented using density functional theory (DFT) and quantitative structure-activity relationship (QSAR) methods. Scandenone proved most potent against Mycobacterium smegmatis (mc2 155) with MIC below 1 μg/mL. In general, it was more potent against Gram-positive bacteria. Scandenone may be a potential tuberculosis medication.Graphical abstract
