This work aims to review the nutritional properties of the Moringa oleifera tree, emphasizing its main constituents and nutritional applications for humans and animals. Moringa oleifera (Moringaceae) is a cosmopolitan tree that grows in many tropical countries showing uncountable folk uses due to its various nutritional and pharmacological applications. The young leaves, flowers and pods are common vegetables in the Asian diet. All parts of this plant are renewable sources of tocopherols (γ and α), phenolic compounds, β-carotene, vitamin C and total proteins, including the essential sulfur amino acids, methionine and cysteine. The seed protein and fat contents are higher than those reported for important grain legumes and soybean varieties, respectively. Unsaturated fatty acids, especially oleic acid, carbohydrates and minerals are present in the seed in reasonable amounts. In general, there are low concentrations of antinutritional factors in the plant, although the seeds possess glucosinolates (65.5µmol/g dry matter), phytates (41g/kg) and hemagglutination activity while the leaves have appreciable amounts of saponins (80g/kg), besides low quantity of phytates (21g/kg) and tannins (12g/kg). Taking into consideration the excellent nutritional properties, the low toxicity of the seeds and the excellent ability of the plant to adapt to poor soils and dry climates, Moringa oleifera can be an alternative to some leguminous seeds as a source of high-quality protein, oil and antioxidant compounds and a way to treat water in rural areas where appropriate water resources are not available.

Cancer is the second most common cause of death in the USA. Among the known classes of anticancer agents, the microtubule-targeted antimitotic drugs are considered to be one of the most important. They are usually classified into microtubule-destabilizing (e.g., Vinca alkaloids) and microtubule-stabilizing (e.g., paclitaxel) agents. Combretastatin A4 (CA-4), which is a natural stilbene isolated from Combretum caffrum, is a microtubule-destabilizing agent that binds to the colchicine domain on β-tubulin and exhibits a lower toxicity profile than paclitaxel or the Vinca alkaloids. In this paper, we describe the docking study, synthesis, antiproliferative activity and selectivity index of the N-acylhydrazone derivatives (5a–r) designed as CA-4 analogues. The essential structural requirements for molecular recognition by the colchicine binding site of β-tubulin were recognized, and several compounds with moderate to high antiproliferative potency (IC50 values ≤18 µM and ≥4 nM) were identified. Among these active compounds, LASSBio-1586 (5b) emerged as a simple antitumor drug candidate, which is capable of inhibiting microtubule polymerization and possesses a broad in vitro and in vivo antiproliferative profile, as well as a better selectivity index than the prototype CA-4, indicating improved selective cytotoxicity toward cancer cells.
