Abstract:
Leishmaniasis is one of the most neglected diseases in modern times, mainly affecting people from developing countries of the tropics, subtropics and the Mediterranean basin, with approximately 350 million people considered at risk of developing this disease. The incidence of human leishmaniasis has increased over the past decades due to failing prevention and therapeutic measures—there are no vaccines and chemotherapy, which is problematic. Acridine derivatives constitute an interesting group of nitrogen-containing heterocyclic compounds associated with numerous bioactivities, with emphasis t

Abstract:
Some new and known substituted 1,2,3,4-tetrahydroacridines incorporated at their position nine with various sulfa drug or thiosemicarbazide moieties were synthesized. Biologically, these compounds were investigated for their antiproliferative activity against human breast cancer (MCF-7) cell line and murine fibroblast normal cell line (BALB/3T3). The results were calculated as the IC<sub>50</sub> (inhibitory concentration 50% i.e. the concentration of tested compound which inhibits 50% of the cells population) compared with Cisplatin as control. Furthermore, a docking simulation study was carr

Abstract:
The catalyst-free sp3 C–H functionalization of tetrahydroacridine(quinolines) derivatives has been achieved using a Michael-type reaction with N-arylmaleimides. This method enables the facile synthesis of biologically important N-aryl bearing tetrahydroacridine(quinolines) moieties in a single step with high yields. The reaction occurs under non-catalytic conditions by heating of hydroacridines(quinolines) in DMSO within 4 h at 100–1200C. The reaction between starting compounds allows synthesizing (3S/4R)-3-[(3R/4S)-9-chloroacridine(quinoline)-4-yl]-1(-N-aryl)pyrrolidine-2,5-diones with a good

Abstract:
1 A class of compounds, 9-aminoacridines, have long been known to be reversible inhibitors of acetyl cholinesterase (AChE - EC 3.1.1.7), the most familiar of which is 9-amino-1,2,3,4-tetrahydroacridine (Tacrine). 2 A novel aminoacridine was synthesised: - 2-tertiary butyl-9-amino-1,2,3,4-tetrahydroacridine (2tBuTHA). 3 In vitro comparisons of the acetylcholinesterase inhibitory potential and neurotoxicity compared to Tacrine were performed using a chemically differentiated neuroblastoma cell line (Neuro 2A). 2tBuTHA, but not Tacrine, was cytotoxic to the neural cell following 20 h exposure, de

Abstract:
Tertiary N-haloethylamines are able to cyclize to the corresponding aziridinium ions. The inhibitory activity of the DSP-4 (N-(o-brombenzyl)-N-ethyl-2-chlorethylamine) and its two derivatives OS-21 (N-benzyl-N-ethyl-2-chloroethylamine) and OS-23 (N-fenylethyl-N-ethyl-2-chloroethylamine) was studied toward rat brain acetylcholinesterase (AChE) in vitro. The influence of the THA (tacrine; 9–amino-1,2,3,4–tetrahydroacridine) on AChE inhibition by these substances was also evaluated. The results demonstrated that all of three aziridinium compounds formed in solution caused a timeand concentration-

Abstract:
Alzheimer’s disease (AD) is neurodegenerative disease that is the cause of 60-70% of dementia cases. The major symptoms of AD involve progressive decline of cognitive and motor skills, caused by neuropathological changes, including elevation of oxidative stress, shrinkage of neurons, formation of Aβ plaques and neurofibrillary tangles in the central nervous system (CNS) and disruption of glutamatergic and cholinergic neurotransmission systems. In AD, the nerve terminal disruption is observed in immediate vicinity of Aβ plaques. Peripheral ionic site of AChE promotes aggregation of Aβ peptides
