Abdominal aortic aneurysm (AAA) is a disease of the aorta characterized by pathological remodeling and progressive weakening of the vessel resulting in the increased risk of rupture and sudden death. In a mouse model of the disease induced by chronic Angiotensin II (AngII) infusion, progression of AAAs is associated with reduced differentiation of smooth muscle cells (SMCs) at the site of lesion development. In the mouse model, the effectiveness of cyclooxygenase-2 (COX-2) inhibition for attenuating AAA progression is associated with maintenance of a differentiated SMC phenotype. However, the safety of COX-2 inhibitors is currently in question due to the increased …

Ethanol causes neurotoxicity via several mechanisms at different points in the cycle of dependence, including neuroinflammation and oxidative stress during ethanol exposure as well as excitotoxicity during ethanol withdrawal. The primary therapeutic implication is that ethanol-induced neurotoxicity requires multifunctional pharmacotherapies which reduce all mechanisms. Using an innovative pharmacological high throughput screening method on a large plant extract library we discovered flavonoids with alpha7 nicotinic acetylcholine receptor (nAChR) activity. In addition to their well-known anti-inflammatory and antioxidant properties, this novel activity means they can potentially reduce excitotoxicity and therefore makes them ideal for inhibition of ethanol-induced neurotoxicity. Rhamnetin, the candidate compound, …
