Article Synopsis
  • Chaga mushroom, a fungus primarily found on birch trees, has been recognized for its traditional use in cancer treatment, and this study explores its chemical makeup and effectiveness against various cancer cells.
  • The research identifies key compounds in chaga extracts, such as inotodiol and betulinic acid, and evaluates their cytotoxic effects on 31 human cancer cell lines using a specific testing method.
  • Results indicate that chaga extracts display moderate anticancer activity, with stronger effects from those growing on specific birch species, particularly against HepG2 and CAL-62 cancer cell lines, suggesting chaga's potential as a source of anticancer compounds.

The pharmaceutical industry usually utilizes either hydrophobic or hydrophilic substances extracted from raw plant materials to prepare a final product. However, the waste products from the plant material still contain biologically active components with the opposite solubility. The aim of this study was to enhance the comprehensive usability of plant materials by developing a new no-waste extraction method for eucalypt leaves and by investigating the phytochemical and pharmacological properties of eucalypt extracts and their 3D-printed dosage forms.

Anxiety disorders are highly prevalent worldwide and can affect people of all ages, genders and backgrounds. Much efforts and resources have been directed at finding new anxiolytic agents and drug delivery systems (DDSs) especially for cancer patients to enhance targeted drug delivery, reduce drug adverse effects, and provide an analgesic effect. The aim of this study was (1) to design and develop novel nanofiber-based DDSs intended for the oral administration of new 1,2,3-triazolo-1,4-benzodiazepines derivatives, (2) to investigate the physical solid-state properties of such drug-loaded nanofibers, and (3) to gain knowledge of the anxiolytic activity of the present new benzodiazepines in rodents in vivo.
