Gyrophoric Acid, a Secondary Metabolite of Lichens, Exhibits Antidepressant and Anxiolytic Activity In Vivo in Wistar Rats.

Gyrophoric acid (GA) is a secondary metabolite of various lichens. It exhibits various biological activities in vitro, but only one study has been carried out in vivo. Because our previous study showed that GA stimulates neurogenesis in healthy rats, the current study aimed to explore the potential of GA during stress-induced depressive-like states in male Wistar rats.

Bioactive Compounds and Their Influence on Postnatal Neurogenesis.

Since postnatal neurogenesis was revealed to have significant implications for cognition and neurological health, researchers have been increasingly exploring the impact of natural compounds on this process, aiming to uncover strategies for enhancing brain plasticity. This review provides an overview of postnatal neurogenesis, neurogenic zones, and disorders characterized by suppressed neurogenesis and neurogenesis-stimulating bioactive compounds. Examining recent studies, this review underscores the multifaceted effects of natural compounds on postnatal neurogenesis.

Exploring the Potential of Cannabinoid Nanodelivery Systems for CNS Disorders.

Cannabinoids have a major therapeutic value in a variety of disorders. The concepts of cannabinoids are difficult to develop, but they can be used and are advantageous for a number of diseases that are not sufficiently managed by existing treatments. Nanoconjugation and encapsulation techniques have been shown to be effective in improving the delivery and the therapeutic effectiveness of drugs that are poorly soluble in water.

Atranorin, a Secondary Metabolite of Lichens, Exhibited Anxiolytic/Antidepressant Activity in Wistar Rats.

Atranorin (ATR) is one of lichens' many known secondary metabolites. Most current studies have investigated the various effects of ATR in vitro and only sporadically in vivo. The latest data indicate that ATR may have anxiolytic/antidepressive effects.
