A series of derivatives of ursolic acid (UA) were synthesised, the anti- activity was tested, and the selectivity index (SI) of these compounds was calculated to determine the derivative with the best anti- activity. Compound A7 showed the best activity against the (IC in infected GES-1 cells: 9.1 ± 7.2 μM), better than the lead compound UA and the positive control drug Spiramycin. Compound A7 was selected for further in vivo research: A7 was tested for its effect on the inhibition rate of tachyzoites in mice and its biochemical parameters, such as alanine aminotransferase, aspartate aminotransferase, glutathione, and malondialdehyde were determined. Compound A7 was evaluated for its anti-Toxoplasma activity and partial damage to the liver. Therefore, the results show that compound A7 could be a potential lead compound for developing a novel anti-Toxoplasma gondii molecule.

Ursolic acid (3-hydroxy-urs-12-ene-28-oic acid, UA) is a pentacyclic triterpene present in numerous plants, fruits and herbs and exhibits various pharmacological effects. However, UA has limited clinical applicability since it is classified as BCS class IV molecule, characterized by low solubility, low oral bioavailability and low permeability. In the present study, UA was isolated from the biomass marc of Lavandula angustifolia and was structurally modified by an induction of indole ring at the C-3 position and amide group at the C-17 position with the aim to enhance its pharmacological potential.

Background: Periodontitis, a chronic inflammatory disease, poses challenges in treatment due to its complex etiology. Tripterygium glycosides (TGs), renowned for their immunosuppressive and anti-inflammatory capabilities, present a prospective therapeutic option for the management of periodontitis. This study delves into the therapeutic efficacy of TGs in periodontitis and reveals the fundamental mechanisms involved.

Active herbal ingredients are gaining recognition for their potent anti-tumor efficacy, attributable to various mechanisms including tumor cell inhibition, immune system activation, and tumor angiogenesis inhibition. Recent studies have revealed that numerous anti-tumor herbal ingredients, such as ginsenosides, ursolic acid, oleanolic acid, and Angelica sinensis polysaccharides, can be utilized to develop smart drug carriers like liposomes, micelles, and nanoparticles. These carriers can deliver active herbal ingredients and co-deliver anti-tumor drugs to enhance drug accumulation at tumor sites, thereby improving anti-tumor efficacy.

This study aimed to assess how ursolic acid (UA) can protect human skin keratinocytes from damage caused by ultraviolet B (UVB) radiation. Utilizing an omics-based approach, we characterized the features of photodamage and investigated the potential of UA to reverse HaCaT cell subpopulation injury caused by UVB radiation. The most significant changes in metabolite levels after UA treatment were in pathways associated with phosphatidylcholine biosynthesis, arginine and proline metabolism.
