Summary: The essential oil isolated from Araucaria heterophylla resin was analyzed, and 24 components were identified, accounting for 99.89% of the total detected constituents. The oil exhibited inhibitory activity against aldose reductase and BuCHE enzymes, possibly due to compounds containing epoxide and hydroxyl groups. This study provides preliminary screening for the oil as potential therapeutic agents for antidiabetic cataract and Alzheimer's disease.

Summary: To improve the bioavailability of caffeic acid, delivery systems were developed using ball milling and freeze-drying techniques to prepare solid dispersions of caffeic acid and magnesium aluminometasilicate. The 1:1 mass ratio solid dispersion obtained from ball milling was the most effective, and its identity was confirmed using X-ray powder diffraction and Fourier-transform infrared spectroscopy techniques. Screening tests demonstrated the improved anti-neurodegenerative activity of caffeic acid with enhanced solubility, inhibiting acetylcholinesterase, butyrylcholinesterase, tyrosinase, and showing antioxidant potential. In silico studies identified the domains of caffeic acid that interacted with enzymes relevant to neuroprotective activity. Furthermore, improved permeability through gastrointestinal tract and blood-brain barrier mimicking membranes validated the in vivo screening tests for anti-neurodegenerative activity.

Summary: Alzheimer's disease (AD) is a neurodegenerative disorder characterized by Aβ aggregation, tau hyperphosphorylation, and loss of cholinergic neurons. AD is also associated with oxidative stress, metal dyshomeostasis, inflammation, and cell cycle dysregulation. In this review, THA-based hybrids are summarized as potential anti-AD agents, highlighting strategies for drug design that have led to cognitive improvements and reduced hepatotoxicity.

Summary: Two undescribed split-ring iridoids (1-2) along with six known triterpenes (3-8) and one steride (9) were isolated from Viburnum chingii. Compound 2 exhibited a novel split-ring iridoid skeleton formed by electrocyclic reaction and split ring. The structures and absolute configurations of the new iridoids were determined using NMR, HRESIMS, and ECD calculations. All the isolated compounds were tested for their AChE inhibitory activity, with compounds 1, 2, 3, 4, and 7 showing significant effects compared to the positive control donepezil. Molecular docking studies were also conducted for these compounds.

Summary: The designed and synthesised pyridinium-2-carbaldoximes with quinolinium carboxamide moiety showed intermediate-to-high inhibition of both cholinesterases compared to standard oximes. In vitro evaluation revealed their reactivation ability on human recombinant acetylcholinesterase (hrAChE) and human recombinant butyrylcholinesterase (hrBChE), with one compound showing reactivation of all used organophosphates on hrAChE, and two novel compounds able to reactivate NIMP/NEMP-hrBChE. The molecular modelling results highlighted the importance of creating a pre-reactivation complex for better reactivation of both cholinesterases.

Summary: The mechanism of toxic action for organophosphates involves persistent inhibition of acetylcholinesterase, leading to hyperstimulation of the nervous system. Differences in their chemistries result in varied metabolism and toxicity. Age-related differences in sensitivity to organophosphates in mammals are primarily influenced by detoxication capacities.

Summary: There is currently no specific treatment for Alzheimer's disease, which is a significant public health concern, especially in developed countries with an aging population. Acetylcholinesterase and butyrylcholinesterase inhibitors have been used to treat this disease. Tyrosinase inhibitors are used preventively for Parkinson's disease, pigmentation disorders, and skin aging. Therefore, there is a need for novel enzyme inhibitors with desirable properties for the treatment of these diseases.

Summary: Acetylated triterpenoids were transformed into succinyl-spacered acetazolamide conjugates and tested for their inhibitory actvity on carbonic anhydrase II and cytotoxicity on human tumor cell lines and non-malignant fibroblasts. The conjugates derived from betulin and glycyrrhetinic acid showed the strongest inhibition, while those derived from ursolic or oleanolic acid were weaker inhibitors but had lower cytotoxicity. A betulin-derived conjugate displayed a Ki value of 0.129 μM and an EC50 value of 8.5 μM for human A375 melanoma cells.

Summary: 36 substituted benzylamides were synthesized from maslinic acid, bredemolic acid, and augustic acid, and their cytotoxicity was evaluated in various human tumor cell lines and non-malignant fibroblasts. The benzylamides derived from maslinic acid exhibited higher cytotoxicity compared to those derived from augustic acid or bredemolic acid. The most effective compound (compound 18, derived from maslinic acid) showed an EC50 value of 1.3 μM against A375 melanoma cells. Further staining experiments revealed that this compound primarily induced apoptosis rather than necrosis.

Summary: Maslinic acid was converted to rhodamine conjugates with different alkyl moieties, which showed high cytotoxicity, especially for A2780 cells. Among them, a propyl substituted rhodamine conjugate exhibited low EC50 values of EC50 = 0.01 μM and was approximately 15 times more cytotoxic to cancer cells than non-malignant fibroblasts (NIH 3 T3). The cytotoxicity was correlated with the lipophilicity of the residues, suggesting an interaction of the conjugates with the inner mitochondrial membrane as they acted as mitocanes.

Summary: Amides and rhodamine B conjugates of pentacyclic triterpene acids have demonstrated excellent cytotoxicity against human tumor cells. The spacer attached to the carboxyl group at ring E determines the cytotoxicity of these conjugates. One acetylated homopiperazinyl spacered rhodamine B conjugate showed high cytotoxicity against ovarian carcinoma cells. These conjugates act as mitocans and induce apoptosis, and have the ability to overcome resistance to standard chemotherapeutic drugs, making them promising candidates for chemotherapy.

Summary: Drimane meroterpenoids have attracted attention for their structural diversity and bioactivity, but the lack of an efficient synthetic route has hindered further development. A nickel-catalyzed decarboxylative cross-coupling method has been established to access a variety of drimane meroterpenoids, featuring mild conditions and tolerance for challenging functional groups. This method enables the scalable synthesis of advanced intermediates for late-stage functionalizations, which has led to the discovery of new antifungal leads against Rhizoctonia solani.

Summary: This study focuses on the development of triterpenoic acid-rhodamine conjugates with fluorescence shifted to the near-infrared (NIR) region for theranostic applications in cancer research. Spectral analysis revealed emission wavelengths around λ = 760 nm, enabling stronger signals and deeper tissue penetration. The conjugates were evaluated using SRB assays on tumor cell lines and non-malignant fibroblasts, demonstrating low nanomolar activity and high selectivity, similarly to their known rhodamine B counterparts. Additional staining experiments proved their mode of action as mitocans.

Mechanistically, G-5b engages the proteasome pathway to degrade ER, inhibiting the ER signaling pathway and inducing apoptosis and cell cycle arrest. In animal models, G-5b exhibited superior pharmacokinetics and pharmacodynamics properties. Overall, G-5b is a promising long-acting SERD worthy of further investigation and optimization.
