Structurally unique C terpenoids, perovsfolins A () and B (), were isolated from the aerial parts of an Uzbek medicinal plant, (Lamiaceae). Their chemical structures including an unprecedented 6/8/6/6/6 pentacyclic carbon skeleton with a C-C ester moiety were elucidated on the basis of spectroscopic analyses aided by density functional theory calculations as well as chemical evidence. Perovsfolin B () exhibited an anti-neuroinflammatory activity.

Traumatic brain injury (TBI) is a life-threatening condition with high incidence and mortality rates. The current pharmacological interventions for TBI exhibit limited efficacy, underscoring the necessity to explore novel and effective therapeutic approaches to ameliorate its impact. Previous studies have indicated that transcranial pulsed current stimulation (tPCS) can improve neurofunctional deficits in patients by modulating brain neuroplasticity.

It is believed that inflammation influences several physiological processes, including the function of the central nervous system. Moreover, the impairment of lipid mechanisms/pathways is associated with neurodegenerative disorders and onset of Alzheimer's disease (AD). AD is a chronic neurodegenerative disease representing the major cause of dementia worldwide.

Prenylated indole diketopiperazines represent a diverse array of alkaloids with complex chemical scaffolds and with a wide range of biological activities. Aiming to discover bioactive metabolites with structural novelty, genomic annotation in association with the MS/MS-based molecular networking demonstrated a deep-sea derived fungus Aspergillus puulaauensis F77 containing a profile of diketopiperazines. Targeted separation of the cultured fungus led to the isolation of 19 undescribed austamide-type diketopiperazines namely versicoines A-S.
