Alzheimer's Disease (AD) is a fatal age-related neurodegenerative condition with a multifactorial etiology contributing to 70% of dementia globally. The search for a multi-target agent to hit different targets involved in the pathogenesis of AD is crucial. In the present study, the neuroprotective effects of four extracts were assessed in LPS-induced AD in mice.

Among the Egyptian species, was reported to be cytotoxic against multidrug-resistant cancer cells. In this context, we aimed to explore the metabolome of and compare it to other members of the genus in pursuance of identifying its bioactive principles.

To study the chemical determinant for antimicrobial activity essential oils (EOs), five species were analyzed including: , , , and . Conventional hydro-distillation (HD) and microwave-assisted extraction (MAE), as new green technologies, were compared for the extraction of essential oils.

We hypothesized that cytotoxic medicinal plants with novel phytochemicals can overcome MDR and kill MDR-cells with similar efficacy as drug sensitive cells.
Purpose: We evaluated plant extracts from an unexplored ecosystem in Egypt with unusual climate and nutrient conditions for their activity against sensitive and multidrug-resistant cancer cell lines.
species are rich in diterpenes. A solvent extraction of , a species indigenous to the Southern Sinai of Egypt, afforded several premyrsinane diterpenoids (⁻) as well as previously reported metabolites (⁻) that included three flavonoids. Isolated compounds were chemically characterized by spectroscopic analysis.

Among marine-derived metabolites, terpenoids have provided a vast array of molecular architectures. These isoprenoid-derived metabolites also exhibit highly specialized biological activities ranging from nerve regeneration to blood-sugar regulation.

The syntheses of such natural products help in obtaining them in bulk amounts. The recognition of microbial biotransformation as important manufacturing tool has increased in chemical and pharmaceutical industries.
