Ca2+ entry through store-operated Ca2+release-activated Ca2+ (CRAC) channels is essential for T-cell activation and proliferation. Recently, it has been shown that 3,5-bistrifluoromethyl pyrazole (BTP) derivatives are specific inhibitors of Ca2+-dependent transcriptional activity in T-cells (Trevillyan, J. M., Chiou, X. G., Chen, Y. W., Ballaron, S. J.,(More)
Brain nicotinic acetylcholine receptors are involved in several neuropsychiatric disorders, e.g. Alzheimer's and Parkinson's diseases, Tourette's syndrome, schizophrenia, depression, autism, attention deficit hyperactivity disorder, and anxiety. Currently, approaches selectively targeting the activation of specific nicotinic acetylcholine receptors are in(More)
A major challenge in neuroscience is identifying the cellular and molecular processes underlying learning and memory formation. In the past decades, significant progress has been made in understanding cellular and synaptic mechanisms underlying hippocampal learning and memory using long-term potentiation (LTP) experiments in brain slices as a model system.(More)
Donepezil is the current standard symptomatic treatment of mild-to-moderate Alzheimer's disease (AD) patients. It aims to compensate for the deficit in cholinergic neurotransmission by blocking acetylcholinesterase (AChE) and thus increases the concentration of extracellular acetylcholine. However, experience from clinical practice demonstrated that AChE(More)
As nicotinic acetylcholine receptor (nAChR) agonists directly address cholinergic neurotransmission with potential impact on glutamatergic function, they are considered as potential new symptomatic treatment options for Alzheimer's disease compared to the indirectly operating acetylcholinesterase inhibitors such as the current gold standard donepezil. In(More)
Rodent selectivity data of piperidine-4-yl-1H-indoles, a series of CC chemokine receptor-3 (CCR3) antagonists, are presented and discussed as part of an overall optimization effort within this lead compound class. Although attachment of an acidic moiety to the 1-position of the indole led to an overall balanced in vitro profile, in particular reducing(More)
INTRODUCTION The hERG (human ether-a-go-go-related gene) potassium channel (KV11.1) is an important anti-target in drug discovery as its inhibition by small molecules has considerable promiscuity and is linked to an increased risk of the potentially fatal ventricular arrhythmia torsade de pointes. Therefore, great efforts are taken in the pharmaceutical(More)
Conflicting findings are reported in the literature about the involvement of the mGlu5 receptor in hippocampal long-term potentiation (LTP), which might be a consequence of different sub-types of LTP induced by the investigators due to the specific experimental conditions used. A comparable controversy came up in the past concerning the influence of(More)
In the present work we develop a predictive QSAR model for the blockade of the hERG channel. Additionally, this specific end point is used as a test scenario to develop and evaluate several techniques for fusing predictions from multiple regression models. hERG inhibition models which are presented here are based on a combined data set of roughly 550(More)
