Alzheimer's disease (AD) is considered to be the most common cause of dementia and is an incurable, progressive neurodegenerative disorder. Current treatment of the disease, essentially symptomatic, is based on three cholinesterase inhibitors and memantine, affecting the glutamatergic system. Since 2003, no new drugs have been approved for treatment of AD.(More)
Chirality is a fundamental property of biological systems and reflects the underlying asymmetry of matter. Interactions of drugs with receptors, enzymes or binding sites have long been known to be stereoselective, and it is increasingly recognized that both pharmacodynamic and pharmacokinetic events contribute to the overall clinically observed(More)
BACKGROUND Epilepsy is a neurological disorder with a worldwide prevalence estimated to be 0.5-1.0% of the population. Many potent antiepileptic drugs (AED) have been used for treatment but still about 30% of patients are resistant to current AEDs. Some AEDs are also used for the treatment of neuropathic pain. OBJECTIVE The aim of this report is to(More)
BACKGROUND Anticancer drugs - oxaliplatin (OXPT) and paclitaxel (PACLI) cause painful peripheral neuropathy activating Transient Receptor Potential (TRP) channels. Here we investigated the influence of 3-[4-(3-trifluoromethyl-phenyl)-piperazin-1-yl]-dihydrofuran-2-one (LPP1) and pregabalin on nociceptive thresholds in neuropathic pain models elicited by(More)
Among the various drug discovery methods, a very promising modern approach consists in designing multi-target-directed ligands (MTDLs). This methodology has been specifically developed for treatment of disorders with complex pathological mechanisms. One such disorder is Alzheimer's disease (AD), currently the most common multifactorial neurodegenerative(More)
A series of novel arylpiperazines bearing a pyrrolidin-2-one fragment was synthesized and evaluated for the binding affinity of the alpha(1)- and alpha(2)-adrenoceptors (AR) and for the antiarrhythmic and hypotensive activities of the compounds. The most potent and selective compound 1-[2-hydroxy-3-[4-[(2-hydroxyphenyl)piperazin-1-yl]propyl]pyrrolidin-2-one(More)
A series of 1-substituted pyrrolidin-2-one and pyrrolidine derivatives were synthesised and tested for electrocardiographic, antiarrhythmic, and antihypertensive activity as well as for alpha(1)- and alpha(2)-adrenoceptors binding affinities. Among the newly synthesised derivatives several compounds with 3-(4-arylpiperazin-1-yl)propyl moiety displayed(More)
Arylpiperazines represent one of the most studied classes of α1 -adrenoceptor (α1 -AR) antagonists. Currently, α1 -AR antagonists are useful in the treatment of benign prostatic hyperplasia, lower urinary tract symptoms or cardiac arrhythmia. The activity of various derivatives of 1-[3-(4-arylpiperazin-1-yl)propyl]pyrrolidin-2-one as α1 -adrenergic receptor(More)
The aim of this study was to evaluate the influence of 3-[4-(3-trifluoromethyl-phenyl)-piperazin-1-yl]-dihydrofuran-2-one (LPP1) on nociceptive thresholds in mouse models of persistent pain. Influence of LPP1 on motor coordination and its antioxidant capacity in mouse brain tissue homogenates were also assessed. Pain sensitivity thresholds in animals(More)
Recently we have shown that 3-[4-(3-trifluoromethyl-phenyl)-piperazin-1-yl]-dihydrofuran-2-one dihydrochloride (LPP1) is an antinociceptive and local anesthetic agent in rodents. Below an extended study of the pharmacological activity of LPP1 is described. In vitro LPP1 has no affinity for GABA(A), opioidergic μ and serotonergic 5-HT(1A) receptors. The(More)
