Identification and quantitation of usnic acid from the lichen Usnea species of Anatolia and antimicrobial activity.
Six species of lichens, such as Usnea florida, Usnea barbata, Usnea longissima, Usnea rigida, Usnea hirta and Usnea subflorida, were collected from different areas of Anatolia (district of Antalya, Karabük, Qankiri, Giresun and Trabzon) in Turkey. Their usnic acid amounts in acetone extracts were determined by HPLC. In addition, antimicrobial activities of these extracts were determined against...

متن کاملAn Antifungal Mechanism of Protolichesterinic Acid from the Lichen Usnea albopunctata Lies in the Accumulation of Intracellular ROS and Mitochondria-Mediated Cell Death Due to Apoptosis in Candida tropicalis
Candida species causes superficial and life-threatening systemic infections and are difficult to treat due to the resistance of these organism to various clinically used drugs. Protolichesterinic acid is a well-known lichen compound. Although the antibacterial activity of protolichesterinic acid has been reported earlier, the antifungal property and its mechanism of action are still largely uni...
متن کاملAntimicrobial peptides: broad-spectrum antibiotics from nature.
No therapeutically useful new classes of antibiotics have been identified in the past quarter of a century This has become of major consequence in the face of the increase in the incidence of significant antibiotic resistance in the past decade. Indeed, strains of several important pathogens have been identified for which very few, or even no, possibilities for antibiotic therapy exist. Althoug...
