This research endeavors to inspect the chemical and biological profiling of methanol and dichloromethane (DCM) extracts prepared from Abutilon figarianum Webb. Total bioactive constituents and secondary metabolites were assessed via ultra-high performance liquid chromatography (UHPLC-MS). Biological effects were evaluated via antioxidant and enzymes inhibitory assays. The methanol extract was able to give the highest phenolic (51.92 mg GAE/g extract) and flavonoid (72.59 mg QE/g extract) contents and was found to contain 11 bioactive metabolites, including flavonoid, alkaloid, phenolic and fatty acid derivatives, as accessed by UHPLC-MS analysis. Similarly, the phytochemical profiling of the DCM extract tentatively identified the 12 different secondary metabolites, most of these were fatty acid derivatives. The methanol extract was most active in the radical scavenging, reducing power and total antioxidant power assays, while dichloromethane extract showed the highest metal chelating activity. For enzyme inhibition, the DCM extract showed the highest activity against cholinesterases, glucosidase and amylase, whereas methanol extract was most active against tyrosinase. Docking studies have supported the observed biological activity, where isobergapten showed higher activity against tyrosinase (−7.63 kcal/mol) with inhibition constant (2.55 µM), as opposed to other enzymes. The observed antioxidant and inhibitory potentials of A. figarianum against the studied enzymes tend to endorse this plant as a prospective source of bioactive phytochemicals.

The Creation

Compounds that act on mitochondrial functions are considered as promising drugs for the treatment of neurodegenerative diseases and age-related dementias. As a basis for the creation of such potential drugs, bioisosteric cinnamic acid analogs and polymethoxybenzene derivatives were selected. Derivatives of cinnamic acid have a wide range of biological activities, which can be important for drugs aimed at the treatment of neurodegenerative diseases, in particular Alzheimer′s disease. In this work, the neuroprotective activity of bioisosteric cinnamic acid analogs and polymethoxybenzene derivatives was studied. Among the compounds studied, lead substances 3, 4, and 7 have been identified. These compounds show no intrinsic toxicity and have a neuroprotective effect on the cellular model of neurodegeneration associated with calcium stress. The mechanism of their cytoprotective activity is probably due to the influence on mitochondrial functions, because these compounds effectively suppress the calcium-induced process of mitochondrial permeability jump. In addition, one of the substances investigated (7) has antioxidant properties, showing the ability to inhibit lipid peroxidation (LPO) of rat brain homogenate, which may be an additional mechanism of neuroprotective effect. The data obtained make it possible to recommend the investigated substances as a basis for the creation of effective neuroprotective drugs capable of influencing early stages of the development of neurodegenerative diseases.

Globally, the use of ethnoveterinary medicine as remedies for animal health among different ethnic groups justify the need for a systematic exploration to enhance their potential. In addition, the increasing popularity and utilisation of woody plants remain common in traditional medicine, which may be attributed to their inherent benefits. The current review was aimed at analysing ethnoveterinary surveys, biological activities, and secondary metabolites/phytochemical profiles of the woody plants of South Africa. Eligible literature (period: 2000 to 2020) were retrieved from different databases such as Google Scholar, PubMed, Sabinet, and Science Direct. Based on the inclusion and exclusion criteria, 20 ethnoveterinary surveys were eligible and were subjected to further analysis. We identified 104 woody plant species from 44 plant families that are used in the treatment of different diseases in animals, particularly cattle (70%) and goats (20%). The most mentioned (with six citations) woody plants were Terminalia sericea Burch. ex DC and Ziziphus mucronata Willd., which were followed by plants with five (Cussonia spicata Thunb., Pterocarpus angolensis DC and Vachellia karroo (Hayne) Banfi & Galasso) or four (Acokanthera oppositifolia (Lam.) Codd, Cassia abbreviata Oliv., and Strychnos henningsii Gilg) individual mentions. The most dominant families were Fabaceae (19%), Apocynaceae (5.8%), Rubiaceae (5.8%), Anacardiaceae (4.8%), Combretaceae (4.8%), Euphorbiaceae (4.8%), Malvaceae (4.8%), Rhamnaceae (4.8%), and Celastraceae (3.8%). Bark (33%), leaves (29%), and roots (19%) were the plant parts dominantly used to prepare remedies for ethnoveterinary medicine. An estimated 20% of woody plants have been screened for antimicrobial, anthelmintic, antioxidant, and cytotoxicity effects. Phytochemical profiles established a rich pool of valuable secondary metabolites (phenolic, flavonoids and condensed tannins) that may be responsible for the exerted biological activities. Overall, the significant portion of woody plants lacking empirical evidence on their biological effects indicates a major knowledge gap that requires more research efforts.
