The Success of Natural Products in Drug Discovery

Abstract: Drug discovery leading to robust and viable lead candidates’ remains a challenging scientific task, which is the transition from a screening hit to a drug candidate, requires expertise and experience. Natural products and their derivatives have been recognized for many years as a source of therapeutic agents and of structural diversity. However, in addition to their chemical structure diversity and their biodiversity, the development of new technologies has revolutionized the screening of natural products in discovering new drugs. Applying these technologies compensates for the inherent limitations of natural products and offers a unique opportunity to re-establish natural products as a major source for drug discovery. The present article attempts to describe the utilization of compounds derived from natural resources as drug candidates, with a focus on the success of these resources in the process of finding and discovering new and effective drug compounds, an approach commonly referred to as “natural product drug discovery”.

Therapeutic and Medicinal Uses of Aloe vera: A Review

Abstract: The plant Aloe vera is used in Ayurvedic, Homoeopathic and Allopathic streams of medicine, and not only tribal community but also most of the people for food and medicine. The plant leaves contains numerous vitamins, minerals, enzymes, amino acids, natural sugars and other bioactive compounds with emollient, purgative, anti-microbial, anti inflammatory, antioxidant, aphrodisiac, anti-helmenthic, antifungal, antiseptic and cosmetic values for health care. This plant has potential to cure sunburns, burns and minor cuts, and even skin cancer. The external use in cosmetic primarily acts as skin healer and prevents injury of epithelial tissues, cures acne and gives a youthful glow to skin, also acts as extremely powerful laxative.

Overcoming the Bell-Shaped Dose-Response of Cannabidiol by Using Cannabis Extract Enriched in Cannabidiol

Abstract: Cannabidiol (CBD), a major constituent of Cannabis, has been shown to be a powerful anti-inflammatory and anti-anxiety drug, without exerting a psychotropic effect. However, when given either intraperitoneally or orally as a purified product, a bell-shaped dose-response was observed, which limits its clinical use. In the present study, we have studied in mice the anti-inflammatory and anti-nociceptive activities of standardized plant extracts derived from the Cannabis sativa L., clone 202, which is highly enriched in CBD and hardly contains any psychoactive ingredients. In stark contrast to purified CBD, the clone 202 extract, when given either intraperitoneally or orally, provided a clear correlation between the anti-inflammatory and anti-nociceptive responses and the dose, with increasing responses upon increasing doses, which makes this plant medicine ideal for clinical uses. The clone 202 extract reduced zymosan-induced paw swelling and pain in mice, and prevented TNFα production in vivo. It is likely that other components in the extract synergize with CBD to achieve the desired anti-inflammatory action that may contribute to overcoming the bell-shaped dose-response of purified CBD. We therefore propose that Cannabis clone 202 (Avidekel) extract is superior over CBD for the treatment of inflammatory conditions.

Corticosteroids and ICU Course of Community Acquired Pneumonia in Egyptian Settings

Abstract: Background: Pneumonia is the most common cause of community-acquired infection requiring ICU admission. 60-87% of patients with severe community acquired pneumonia (CAP) admitted to the ICU develops respiratory failure and require mechanical ventilation (MV). Objectives: To assess the efficacy and safety of adjunctive low dose hydrocortisone infusion treatment in Egyptian ICU patients with CAP. Methods: Hospitalized patients, clinically and radiologically diagnosed with CAP, were randomized to receive hydrocortisone 12.5 mg/h IV infusion for 7 days or placebo, along with antibiotics. The end-points of the study were improvement in PaO2:FIO2 (PaO2:FIO2 > 300 or ≥100 increase from study entry) and SOFA score by study day 8 and the development of delayed septic shock. Results: 80 patients were recruited, 40 of them received hydrocortisone and the remaining 40 received placebo. By study day 8, hydrocortisone treated patients showed a significant improvement in PaO2:FIO2 and chest radiograph score, and a significant reduction in C-reactive protein (CRP) levels, Sepsis-related Organ Failure Assessment (SOFA) score, and delayed septic shock compared to the control group. Hydrocortisone treatment was associated with a significant reduction in the duration of MV. However, hydrocortisone infusion did not show significant difference in the ICU mortality. Conclusions: adjunctive 7-day course of low dose hydrocortisone IV in patients with CAP hastens recovery of pneumonia and prevents the development of sepsis related complications with a significant reduction in duration of the mechanical ventilation.
