“…Their anti-inflammatory effects [36], antimalarial activity [37], neuroprotective activities [38] have also been reported. They are also selective inhibitor of acetylcholinesterase (AChE) [39,40] with promising potential as therapeutic option for Alzheimer's disease treatment [41]. Our findings are consistent with the report of Shafika et al, [42]; they identified major polyphenols in avocado seeds to be catechin and pyrogallol, hesperidin, naringin and rutin.…”

Aims: Persea americana (P. americana) dubbed ‘green gold’ is a highly sought after fruit today, with insatiable export market. Different parts of avocadoes have been consumed both for nutritional and health benefits across regions of the world. Therefore, this study investigates the bioactive composition of P. americana seed ethyl acetate fraction and acute toxicological effects. Place and duration of study: Department of Biochemistry, Federal University of Technology Owerri, Imo State, Nigeria; between May 2019 and October, 2019. Methodology: Quantitative phytochemical composition was assessed using gas chromatography fitted with flame ionization detector (GC-FID) and acute toxicity determined using standard method. Results: Result of quantitative phytochemical composition of P. americana seed fraction shows a rich presence of phytochemicals such as epicatechin, kaempferol, proanthocyanin, rutin, resveratrol, ribalinidine, naringin, spartein, quinine, flavan-3-ol, anthocyanin, lunamarin, sapogenin, flavonones, flavones. The quantitative phytochemical composition of P. americana seed shows that among other phytochemicals, the seed is relatively rich in anthocyanin, quinine, epicatechin, tannin and proanthocyanin with concentrations of 69.39 ± 8.33 µg/g, 22.16 ±1.77 µg/g, 21.88 ± 2.53 µg/g, 19.86 ± 1.19 µg/g and 10.98 ± 0.55 µg/g respectively. The acute toxicity studies on the seed reveal that the ethyl acetate fraction of P. americana seed did not elicit any lethal signs of morbidity and mortality at doses up to 5000mg/Kgb.wt. and are therefore considered generally safe. Conclusion: P. americana seed ethyl acetate fraction contains essential phytochemicals with useful phyto-medicinal and nutraceutical benefits. The implications of these findings are further discussed.

“…A molecule is said to have more favorable binding modes with a better fit if the FF score shows greater negative value . The docked conformations having the lowest binding energy were selected for discussion . However, for the most favorable interaction, if a molecule has a small docking score, then it is said to have a higher binding affinity of ligands for a particular receptor .…”

Physicochemical and Pharmacokinetic Analysis of Anacardic Acid Derivatives

Anacardic acid (AA) and its derivatives are wellknown for their therapeutic applications ranging from antitumor, antibacterial, antioxidant, anticancer, and so forth. However, their poor pharmacokinetic and safety properties create significant hurdles in the formulation of the final drug molecule. As a part of our endeavor to enhance the potential and exploration of the anticancer activities, a detailed study on the properties of selected AA derivatives was performed in this work. A comprehensive analysis of the drug-like properties of 100 naturally occurring AA derivatives was performed, and the results were compared with certain marketed anticancer drugs. The work focused on the understanding of the interplay among eight physicochemical properties. The relationships between the physicochemical properties, absorption, distribution, metabolism, and excretion attributes, and the in silico toxicity profile for the set of AA derivatives were established. The ligand efficacy of the finally scrutinized 17 AA derivatives on the basis of pharmacokinetic properties and toxicity parameters was further subjected to dock against the potential anticancer target cyclin-dependent kinase 2 (PDB ID: 1W98). In the docked complex, the ligand molecules (AA derivatives) selectively bind with the target residues, and a high binding affinity of the ligand molecules was ensured by the full fitness score using the SwissDock Web server. The BOILED-Egg model shows that out of 17 scrutinized molecules, 3 molecules exhibit gastrointestinal absorption capability and 14 molecules exhibit permeability through the blood−brain barrier penetration. The analysis can also provide some useful insights to chemists to modify the existing natural scaffolds in designing new anacardic anticancer drugs. The increased probability of success may lead to the identification of drug-like candidates with favorable safety profiles after further clinical evaluation.

“…The current treatment of AD is only symptomatic and mainly involves restoring of acetylcholine (ACh) levels through acetylcholinesterase (AChE) inhibition [ 71 ]. Three AChE inhibitors, namely donepezil, galanthamine ( 13 ) and rivastigmine, are currently used as the main therapeutic option for AD treatment [ 72 ]. Since the Amaryllidaceae alkaloid galanthamine ( 13 ) has been introduced into clinical practice, other Amaryllidaceae alkaloids have received attention as potential AChE inhibitors [ 5 , 73 , 74 , 75 , 76 ].…”

Lycoris Herbert, family Amaryllidaceae, is a small genus of about 20 species that are native to the warm temperate woodlands of eastern Asia, as in China, Korea, Japan, Taiwan, and the Himalayas. For many years, species of Lycoris have been subjected to extensive phytochemical and pharmacological investigations, resulting in either the isolation or identification of more than 110 Amaryllidaceae alkaloids belonging to different structural types. Amaryllidaceae alkaloids are frequently studied for their interesting biological properties, including antiviral, antibacterial, antitumor, antifungal, antimalarial, analgesic, cytotoxic, and cholinesterase inhibition activities. The present review aims to summarize comprehensively the research that has been reported on the phytochemistry and pharmacology of the genus Lycoris.
