Special Issue Information

Dear Colleagues,

Plant-based products derived from various plant parts (leaves, roots, etc.) that have biological activity offer a huge and relatively unexplored reservoir of new therapeutic agents with potential benefits for treating, preventing, or alleviating diseases with fewer side effects and sustainable supply. These products include a diverse array of chemical substances such as flavonoids, terpenoids, polyphenols, and alkaloids, which have been found to possess diverse biological activities through multiple mechanisms of action. The vast chemical diversity can lead to the discovery of novel bioactive compounds in the treatment and management of highly prevalent diseases such as cardiovascular and neurodegenerative disorders. Chronic inflammation is a critical factor in the pathogenesis of these health conditions, and plant-based compounds, known for their anti-inflammatory, antioxidant, and multi-targeted properties, offer promising therapeutic avenues. Exploring and utilizing plant-based bioactive products are becoming increasingly crucial for the development of innovative drugs that can address unmet human medical needs.

This Special Issue aims to explore the potential of herbal bioactive products in the field of pharmaceuticals applied to human health. The focus of this Special Issue will be on the discovery, characterization, and application of bioactive compounds from plants, emphasizing their therapeutic potential, mechanisms of action, and advantages over currently available drugs.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

  • Discovery and isolation of novel bioactive compounds from plants.
  • Pharmacological activities and mechanisms of action.
  • Preclinical and clinical studies.
  • Pharmacokinetics, toxicokinetics, and pharmacodynamics.
  • Cardiovascular, neurodegenerative, and metabolic diseases.

We look forward to receiving your contributions.

Background: Gluten-related disorders, particularly celiac disease, are triggered in susceptible individuals by the toxic effects of gluten, the major storage protein of wheat grains. This toxicity can be reduced by wheat glutenases. Members of the papain-like cysteine protease family, which can act in the human gastrointestinal tract, are promising candidates for the enzymatic treatment of celiac disease. Methods: Two wheat proteases were selected using AlphaFold2, produced in recombinant forms, and characterized. Their glutenase potentials under acidic or slightly acidic conditions were evaluated and compared with the properties of the previously characterized wheat glutenase Triticain-α. Results: All enzymes tested, Ta-P7, Ta-V6, and Triticain-α, were able to hydrolyze the model substrate (α-gliadin-derived epitope) in the pH range of 3.6–7.5. Nevertheless, Triticain-α performs the most efficient hydrolysis of the peptide substrate under the conditions of the gastrointestinal tract, according to its kinetic characteristics. In the wheat gluten degradation experiment at pH 4.6 and 37 °C, both Ta-P7 and Triticain-α cleaved the mixture almost completely within 5 min. In addition, Triticain-α and Ta-P7 significantly reduced the levels of toxic peptides compared to both intact gluten and gluten treated with pepsin-trypsin digestion as tested by the Ridascreen Gliadin Kit. Conclusions: Novel wheat proteases under investigation possess the expected glutenase activity to varying degrees; however, Triticain-α is a primary candidate for potential use in the enzymatic therapy of gluten-related disorders.

Background/Objectives: Psoriasis, a prevalent dermatological disorder, poses therapeutic challenges due to limited effective treatments or adverse side-effects. Traditional medicinal plants like Alstonia scholaris and Wrightia tinctoria, historically used in Ayurvedic and Siddha practices, show potential in treating inflammatory skin diseases. This study aims to explore their in vitro and in vivo anti-psoriatic properties to develop safer and more effective therapies. Methods: Chloroform:methanol fractions from ethanol extracts of Alstonia scholaris and Wrightia tinctoria were evaluated for anti-psoriatic activity. In vitro assays using HaCaT cells assessed cell viability, apoptosis, and inflammatory markers. In vivo studies utilized an IMQ-induced psoriasis mouse model, evaluating skin lesions, histopathology, and cytokine profiles. Results: Chloroform fractions significantly reduced HaCaT cell viability and induced apoptosis. They also dose-dependently downregulated IL-8 and RANTES levels. In vivo, these fractions reduced skin inflammation, edema, and psoriasis scores. Histopathological analysis showed decreased epidermal thickness and dermal inflammation. Key psoriasis biomarkers IL-17 and IL-23 were significantly reduced. Conclusions: Chloroform:methanol fractions from Alstonia scholaris and Wrightia tinctoria demonstrated potent anti-psoriatic effects in vitro and in vivo. These findings support their potential as novel phytotherapeutic agents for managing psoriasis, offering promise for further development and clinical application. Full article

Background: Anxiety disorders have a 7.3% worldwide prevalence and, considering the long period of treatment, developing new efficient and safer pharmacological tools is critical. Essential oils consist of highly concentrated lipophilic compounds from plants with therapeutic potential effects, such as Lavandula burnatii, produced in Córdoba, Argentine, with high levels of active pharmaceutical ingredients in its essential oil (linalyl acetate and linalool). The evidence indicates that lavender essential oil could induce anxiolytic effects; however, more systematic studies are needed. Methods: To test the anxiolytic attributes of Lavandula burnatii, male Wistar rats (200–260 g) were injected intraperitoneally with two different doses of essential oil (30/80 mg/kg) or vehicle (Myritol 318, a high-purity vegetable oil), once (acute) or for 7 days. One hour after the last administration, the anxiolytic effects were evaluated using the following behavioral tests: the dark–light test and the elevated plus maze test. The open-field test was used to assess locomotor activity. Results: Our results showed that the lower dose of lavender essential oil induces anxiolytic effects since it increases the time spent in the aversive compartment in each evaluation. The acute administration has no impact on the behaviors evaluated. The higher dose is comparable with the control group and does not show significant differences. Conclusions: More studies are needed to better characterize the beneficial effects of this essential oil for anxiety disorders and to establish an adequate dosage range. Full article
