Hydrosols, also named hydrolates or aromatic waters, are considered distillation by-products obtained during essential oil extraction from herbs or spices, which are usually discarded.

Aloe vera leaf pulp has been utilized for over 5000 years as a medicinal plant by various civilizations, including the Egyptians, Romans, and Indigenous peoples of Africa, Asia, and the Americas

The aim of this work was to obtain a mixture of polyphenols and polysaccharides, extracted from forest fruit pomace (a side stream of forest fruit juice production) and chia seeds with a synergic antioxidant activity that will be further encapsulated and used in a fortified protein bar

During essential oil preparation from aromatic plants, floral waters or hydrosols or hydrolates are obtained as by-products presenting inhibitory effects on phytopathogenic fungi growth, while avoiding the main problem of soil accumulation observed for currently used fungicides

Prostaglandins (PGs) with cytoprotective activity were studied for a long time, and a few PGE₁ and PGE₂ stable analogues were promoted as drugs: arbaprostil, enprostil, misoprostol, and rioptostol. Similarly, nocloprost, a 9β-chlorine prostaglandin analogue, and many 9β- and 11β-substituted prostaglandins were synthesized and studied for their biological activity. We previously synthesized new 9β-halogenated prostaglandins with an ester group at the carbon atom 6 (PGs numbering) by the reaction of a δ-lactone intermediate with diols in acid catalysis. These compounds were used in the current molecular docking study to determine their potential cytoprotective (anti-ulcer) activity. The current study was done with the CLC Drug Discovery Workbench 2.4. software and an oxidoreductase enzyme receptor, chosen from the Protein Data Bank, ID: 4KEW (www.rcsb.org). We used two recognized drugs, omeprazole (co-crystallized with the enzyme) and nocloprost, as the standard. The 9β-halogenated prostaglandin analogs were docked. Nocloprost and all 9β-halogenated compounds had docking scores greater than that of omeprazole. The majority of the 9β-halogenated analogs had docking scores even greater than that of nocloprost, indicating that these compounds could have potential cytoprotective (anti-ulcer) activity. A few correlations between docking score and substituents on the prostaglandin skeleton were found.

Drugs belonging to the quinolone compounds are characterized by a quicker biological activity and a broad antibacterial spectrum [1–4].
