In this paper, we have attempted a theoretical calculation of some plant-isolated compounds as potential inhibitors of oxidative stress and Advanced Glycation Endproducts (AGEs). Herein, theoretical reactivity indices based on the CDFT theory were computed to explore the reactivity of five isolated products from Global reactivity indices based on HOMO and LUMO energy such as electronic chemical potential, hardness, electrophilicity and the local reactivity descriptors Parr function, molecular electrostatic potentials(MEP), electrostatic potential (ESP) and thermodynamic parameters for the studied compounds are computed and discussed using DFT method and two functionals B3LYP and CAM-B3LYP with 6-31 G(d,p) basis set. The free radical scavenging activity mechanisms (HAT, SET-PT, and SPLET) of some of the isolated products with DPPH are also presented in this work.

Investigating this species and its separated components chemical make-up and radical scavenging capacity, was the main goal. Using an online HPLC-ABTS˙ test, ORAC, and TEAC assays, the free radical scavenging capacity of the ethyl acetate extract was assessed.

Aqueous extracts were administrated to Wistar rats in bronchial-inflammation experimentally induced by an allergen and ovalbumin, administered intraperitoneally / intranasally (20mg/kg/day). Experimentation showed disturbances in bronchoalveolar fluid with increased leukocyte and lymphocyte levels as well as IL-4 concentration in the lungs and erythrocytes associated with high lipid peroxidation.

Additionally, the study aims to analyze the obtained results through studies; by conducting experiments and utilizing theoretical methods. In this context, we investigated the cytotoxic activity of enastron analogues on three human cell lines PRI (lymphoblastic cell line) derived from B-cell lymphoma.

These pseudonucleosides are synthesized in good yields starting from chlorosulfonyl isocyanate and --glucosamine hydrochloride in five steps; (protection, acetylation, removal of the Boc group, sulfamoylation, and cyclization). Further, novel glycosylated sulfamoyloxazolidin-2-one is prepared in three steps; carbamoylation, sulfamoylation, and intramolecular cyclization.

Many treatments of phobias exist and are based on plant extracts therapies, which play an important role in the amelioration of the behavior. Our study aimed to evaluate the adaptogenic activity of different essential oils provided from local plants: Cinnamomum camphora (Camphora), Eucalyptus globulus (Blue gum), Lavandula stœchas (Topped lavender) and Rosmarinus officinalis (Rosemary) on Wistar rats.

Background And Aim: In the present study, we investigate the phytochemical composition and the nephroprotective effects as well as the antioxidant properties of aqueous extract in alloxan-induced experimental diabetes in rats.
Experimental Procedure: Wistar rats were divided into four groups of seven rats each: Group I: Normal control (NC) received saline solution at 9‰ given by intraperitoneal way; Group II: Diabetic control (DC) received alloxan (150 mg/kg b.w) intraperitoneally; Group III: Normal control (NC + AHA) received saline solution at 9‰ and treated orally by AHA aqueous extract (400 mg/kg/b.
In the search for effective methods of biological control of stored products insect-pests, the essential oil of Origanum vulgaris was extracted using Clevenger apparatus and tested on reproduction and mortality of flour moth Ephestia kuehniella. Bio-insecticide works with a double action mechanism; administered by inhalation in pupae, essential oil affects their pupal development. It also disrupts the reproduction of exuviated adults by extending the preoviposition period and reducing the period of egg laying and fecundity because fecundated females cannot live more than four days compared to control group.

The present study was undertaken to evaluate the protective effect of Artemisia herba alba (AHA) leaf powder against alloxane-induced oxidative damage in diabetic rats. Rats were randomly divided into four groups: Group I controls received saline solution 9%; Group II was treated with 150 mg alloxane/(kg body weight) administered by intraperitoneal.
