Background/aims: Xylopic acid (XA) has been reported to exhibit analgesic activity, alleviate neuropathic pain in rodents, and demonstrate anti-inflammatory effects. Intrarectal challenge of rats with acetic acid induces colitis that bears resemblance in terms of its pathogenesis, histopathology, and inflammatory profile to that in humans. Reactive oxygen species are implicated as the main driving force in this inflammatory bowel disease. This study aimed to investigate the anti-colitic potential of XA.
Materials And Methods: We investigated the effect of XA on body weight, disease activity, inflammatory cell infiltration, and generation of reactive oxygen species. Rats were treated with XA or sulphasalazine, challenged intrarectally with acetic acid with macroscopic and microscopic findings made after eight days.
Results: Administration of XA to rats with colitis resulted in an increase in body weight with significant (p<0.05) improvement of the disease profile macroscopically. We observed decreased gross mucosal injury, reduced inflammation, and cellular proliferation with XA administration. Treatment with XA also resulted in decreased colonic epithelial expression of argyrophylic nucleolar organizer regions (AgNORs) with significant decrease (p<0.0001) in the quantitative expression of AgNORs/nucleus ratio to levels comparable with non-colitic control. We also observed reduced proliferation of mucosal mast cell in the colonic segment of the rats treated with XA. Treatment with XA also significantly (p<0.0001) increased the activity of SOD, CAT, and APx while it decreased the activity of MPO and MDA levels.
Conclusion: Xylopic acid possesses anti-colitic activity in rats induced with acetic acid colitis.
Parkinson disease is a neurogenerative disease common in adults and results in different kinds of memory dysfuntions. This study evaluated the monoamine oxidase B (MAO-B) inhibitory potential of kaurane diterpenoids previously isolated from Xylopia aethiopica through comprehensive computational approaches. Molecular docking study and molecular dynamics simulation were used to access the binding mode and interaction of xylopic acid and MAO-B enzyme.
Background: Xylopic acid (XA), a kaurene diterpene from the dried fruits of has anxiolytic- and antidepressant-like activity in mice and zebrafish. We aimed to assess the potential synergistic antidepressant-like effects of XA when combined with selected antidepressants in the mouse forced-swim test.
Materials And Methods: The antidepressant-like effect of xylopic acid (XA) (10, 30, 100 mgkg), fluoxetine (Flx) (3, 10, 30 mgkg), sertraline (Sert) (3, 10, 30 mgkg), imipramine (Imi) (10, 30, 100 mgkg-1) and ketamine (Ket) (0.
Objective: Secondary metabolites and polyphenolic compounds from medicinal plants have been demonstrated to have multiple biological functions with promising research and development prospects. This study examined the effect of -stigmasterol (with ergosterol) and xylopic acid isolated from on liver mitochondrial permeability transition pore (mPTP).
Methods: The compounds were isolated by vacuum liquid chromatography.

Stability studies of active pharmaceutical ingredients (APIs) remain an essential quality requirement of the pharmaceutical industry. Stability data of an API could guide in the choice of its processing technique, packaging method and storage conditions. Here, we sought to determine the stability or otherwise of xylopic acid (XA) under various stress conditions as stipulated by the International Conference on Harmonization (ICH).
