Fecha de publicación: | 2021 | Editor: | Elsevier | Citación: | Saudi Pharmaceutical Journal 29: 236-243 (2021) | Resumen: | Salvia species have been traditionally used to improve cognition and have been proved to be a potential natural treatment for Alzheimer's disease. Salvia fruticosa Mill. (Turkish sage or Greek sage) demonstrated to have anticholinergic effects in vitro. The aim of this study was to understand the mechanism underlying the neuroprotective effects of S. fruticosa infusion and its representative compound rosmarinic acid, which was detected by LC-DAD-ESI-MS/MS. The protective effects of the S. fruticosa infusion (SFINF) and its major substance rosmarinic acid (RA) on amyloid beta 1–42 -induced cytotoxicity on SH-SY5Y cells together with p-GSK-3β activation were investigated. Their in vitro inhibitory effects against glycogen synthase kinase 3β, β-secretase, and casein kinase 1δ enzymes were also evaluated. The results showed that treatment with the all tested concentrations, SFINF significantly decreased Aβ 1–42-induced cytotoxicity and exhibited promising in vitro glycogen synthase kinase 3β inhibitory activity below 10 µg/mL (IC 6.52 ± 1.14 µg/mL), in addition to β-secretase inhibition (IC 86 ± 2.9 µg/mL) and casein kinase 1δ inhibition (IC 121.57 ± 4.00). The SFINF (100 µg/mL and 250 µg/mL) also activated the expression of p-GSK-3β in amyloid beta 1–42 treated SH-SY5Y cells. The outcomes of this study demonstrated that the S. fruticosa infusion possessed activity to prevent amyloid beta 1–42 -induced neurotoxicity and provided proof that its mechanism may involve regulation of p-GSK-3β protein. | Descripción: | The authors would like to thank Dr. Ana Martinez (CSIC-CIB) for her kind and valuable support concerning the enzyme assays.
