Additionally, the binding afnity of tanshinone Cabozantinib I to GABAA receptors is only moderate, and thus, it can be unlikely that the ameliorating effect of tanshinone I on diazepam induced studying and memory impairment is directly derived from its binding to GABAA receptors.
In addition, activation of NMDA receptors as well as the resulting Ca2 inux activate CaMKII, which in turn activates Ras GTP, which initiates a series of kinase cascades, like the Raf 1, MAP kinase/ERK kinase and ERK cascades. Accordingly, blockade on the Cabozantinib NMDA receptor can reduce ERK activation. Conversely, increased ERK activation can attenuate NMDA receptor blockade induced physical and behavioural changes. Furthermore, in the present study, we found that ERK and CREB were hyperphosphorylated in the hippocampal tissues of mice that had completed the acquisition trial in the passive avoidance task, but that this phosphorylation was lower in MK 801 treated mice. In addition, tanshinone I reversed the MK 801induced inhibition of ERK and CREB phosphorylation in the hippocampal tissues of mice that performed the acquisition trial.
These results suggest that ERK phosphorylation and downstream CREB phosphorylation play crucial roles in tanshinone I induced learning and memory enhancement. Moreover, ERK phosphorylation should be a common pathway for the learning and memoryrelated NSCLC behavioural changes observed after GABAA receptor agonist or NMDA receptor antagonist treatment, which suggests that the ERK cascades in the hippocampus are a potential target for the development of a cognitive improvement agent. In conclusion, the present study demonstrates that tanshinone I can increase signalling by ERK/CREB in the hippocampus, and enhance learning and memory. Moreover, tanshinone I was found to reverse the learning and memory impairments associated with NMDA or GABAA receptors by activating ERK signalling in the hippocampus.
Verapamil is the most extensively characterized P gp inhibitor and multidrug resistance associated protein reversal agent. It is also reported that coadministration of verapamil with a recognized antidepressant improves the clinical outcome in previously resistant cases and the Cabozantinib inhibition of P gp was a potential mechanism of action for verapamil during treatment resistant depression. Danshen, the dried root of Salvia miltiorrhiza Bunge, is widely used for the treatment of various microcirculatory disturbance related diseases, such as cardiovascular disease, liver dysfunction, and cerebrovascular disease. Chemical constituents of Salvia miltiorrhiza Bunge are classied into two major categories: lipophilic compounds and hydrophilic compounds.
Studies have showed that lipophilic compounds Tanshinone I, Tanshinone IIA, Cryptotanshinone, and 15, 16dihydrotanshinone I had the ability to ameliorate memory decits induced by scopolamine, Tanshinone IIA and 2 Tanshinone IIB could lead to reduction of brain infarct volume and the Capecitabine restoration of neurological function in an experimental model of stroke in mice, Cryptotanshinone could improve the cognitive ability in Alzheimers disease transgenic mice.
