Biological Evaluation of Extracts from Argentina with Potent Cholinesterase Inhibition for the Treatment of Neurodegenerative Disorders and Their Comorbidities-The Case of Sm. (Caprifoliaceae) Studied in Mice.

Alzheimer's disease (AD) is a neurodegenerative disorder whose pathophysiology includes the abnormal accumulation of proteins (e.g., β-amyloid), oxidative stress, and alterations in neurotransmitter levels, mainly acetylcholine.

Inhibitory effect of medicinal herbs against RNA and DNA viruses.

Fifteen Argentine medicinal plants were tested for their antiviral activity in vitro against herpes simplex viruses types 1 and 2 (HSV-1 and 2), bovine viral diarrhoea virus type 1 (BVDV-1), influenza virus type A (Inf A) and human immunodeficiency virus type 1 (HIV-1). Antiviral activity was evaluated by a reduction in cytopathic effect, plaque-forming units and p24 HIV-1 antigen. The Selective Index of the active extract (SI(extract) = CC50(extract)/EC50(extract)) of Coronopus didymus (SI(extract) = 110.
