Abstract
Donepezil is a centrally acting acetylcholinesterase (AChE) inhibitor with therapeutic potential in inflammatory diseases; however, the underlying autonomic and cholinergic mechanisms remain unclear. Here, we assessed effects of donepezil on mean arterial pressure (MAP), heart rate (HR), HR variability, and body temperature in conscious adult male C57BL/6 mice to investigate the autonomic pathways involved. Central versus peripheral cholinergic effects of donepezil were assessed using pharmacological approaches including comparison with the peripherally acting AChE inhibitor, neostigmine. Drug treatments included donepezil (2.5 or 5 mg/kg sc), neostigmine methyl sulfate (80 or 240 μg/kg ip), atropine sulfate (5 mg/kg ip), atropine methyl bromide (5 mg/kg ip), or saline. Donepezil, at 2.5 and 5 mg/kg, decreased HR by 36 ± 4% and 44 ± 3% compared with saline (n = 10, P < 0.001). Donepezil, at 2.5 and 5 mg/kg, decreased temperature by 13 ± 2% and 22 ± 2% compared with saline (n = 6, P < 0.001). Modest (P < 0.001) increases in MAP were observed with donepezil after peak bradycardia occurred. Atropine sulfate and atropine methyl bromide blocked bradycardic responses to donepezil, but only atropine sulfate attenuated hypothermia. The pressor response to donepezil was similar in mice coadministered atropine sulfate; however, coadministration of atropine methyl bromide potentiated the increase in MAP. Neostigmine did not alter HR or temperature, but did result in early increases in MAP. Despite the marked bradycardia, donepezil did not increase normalized high-frequency HR variability. We conclude that donepezil causes marked bradycardia and hypothermia in conscious mice via the activation of muscarinic receptors while concurrently increasing MAP via autonomic and cholinergic pathways that remain to be elucidated.

Abstract
Mushroom polysaccharides are active medicinal compounds that possess immune-modulatory and anticancer properties. Currently, the mushroom polysaccharides krestin, lentinan, and polysaccharopeptides are used as anticancer drugs. They are an unexplored source of natural products with huge potential in both the medicinal and nutraceutical industries. The northern parts of Pakistan have a rich biodiversity of mushrooms that grow during different seasons of the year. Here we selected an edible Morchella esculenta (true morels) of the Ascomycota group for polysaccharide isolation and characterization. Polysaccharopeptides and polysaccharides from this mushroom were isolated using the green chemistry, hot water treatment method. Fourier transform infrared spectroscopy revealed the sugar nature and possible beta-glucan type structure of these polysaccharides. Antioxidant assays showed that the deproteinized polysaccharides have moderate free radical scavenging activity. These isolated polysaccharides exhibited good acetylcholinesterase (AChE) and butyryl cholinesterase (BChE) inhibition activities. Therefore, these polysaccharides may be valuable for the treatment of Alzheimer's and Parkinson's diseases. Further bioassays are needed to discover the true potential of M. esculenta polysaccharides for medicinal purposes.

Abstract
:
Alzheimer, a progressive disease, is a common term for memory loss which interferes with
daily life through severe influence on cognitive abilities. Based on the cholinergic hypothesis, and Xray
crystallographic determination of the structure of acetylcholinesterase (AChE) enzyme, the level of
acetylcholine (ACh, an important neurotransmitter associated with memory) in the hippocampus and
cortex area of the brain has a direct effect on Alzheimer. This fact encourages scientists to design and
synthesize a wide range of acetylcholinesterase inhibitors (AChEIs) to control the level of ACh in the
brain, keeping in view the crystallographic structure of AChE enzyme and drugs approved by the Food
and Drug Administration (FDA).
:
AChEIs have slightly diverse pharmacological properties, but all of them work by inhibiting the segregation
of ACh by blocking AChE. We reviewed significant scaffolds introduced as AChEIs. In some
studies, the activity against butyrylcholinesterase (BuChE) has been evaluated as well because BuChE
is a similar enzyme to neuronal acetylcholinesterase and is capable of hydrolyzing ACh. In order to
study AChEIs effectively, we divided them structurally into 12 classes and briefly explained effective
AChEIs and compared their activities against AChE enzyme.

Abstract
Background:
Adamantane derivatives possess multiple pharmacological activities such
as antiviral, anticancer, antimycobacterial, antidiabetic, antiparkinsonian and others. The interest of
medicinal chemists in adamantane compounds is due to their unique spatial structure, high lipophilicity,
and carbon cage rigidity. As a result, these molecules can easily penetrate biological lipid
membranes and often have unique target-specific activity profile. Another pharmacophore studied in
this work is pyridoxine (vitamin B6). Pyridoxine plays highly important roles in living cells as a key
cofactor of many enzymes. On the other hand, its molecular scaffold is a valuable structural platform
which has led to the development of several launched drugs (Pyritinol, Pirisudanol, Cycletanine,
Mangafodipir) and a wide number of preclinical and clinical drug candidates.
Objective:
The objective of this study is a synthesis of pyridoxine-adamantane and pyridoxinecyclooctane
dipharmacophore molecules. The underlying idea was to assess the antibacterial and
antiviral potential of such dipharmacophores, based on multiple examples of promising antiinfective
agents which have in their structures adamantane and pyridoxine moieties. Another specific reason
was to explore the ability of pyridoxine pharmacophore to suppress the potential of microbial pathogens
to develop resistance to drug molecules.
Methods:
In this study, a series of pyridoxine-adamantane and pyridoxine-cyclooctane dipharmacophore
molecules were synthesized based on reactions of three different cycloalkyl amines with the
corresponding electrophilic derivatives of pyridoxine aldehydes, chlorides and acetates. All synthesized
compounds have been tested for their in vitro activity against M. tuberculosis H37Rv strain and
H3N2 (A/Aichi/2/68) influenza virus.
Results:
Series of pyridoxine-adamantane and pyridoxine-cyclooctane dipharmacophore molecules
were synthesized based on reactions of three different cycloalkylamines with the corresponding
electrophilic derivatives of pyridoxine aldehydes, chlorides and acetates. Reaction of cycloalkylamines
with pyridoxine derivatives, in which meta-hydroxyl and ortho-hydroxymethyl groups are
protected by acetyl groups, represents a useful alternative to reductive amination of aldehydes and
nucleophilic substitution of alkyl halides. According to a tentative mechanism, it proceeds via paraand
ortho-pyridinone methides which readily react with nucleophiles. None of the synthesized dipharmacophore
compounds showed activity against M. tuberculosis H37Rv strain. At the same time,
three compounds demonstrated some antiviral activity against H3N2 (A/Aichi/2/68) influenza virus
(EC50 52-88 µg/mL) that was comparable to the activity of Amantadine, though lower than the activity
of Rimantadine. The results of this work can be useful in the design of physiologically active
derivatives of pyridoxine and adamantane.
Conclusion:
The results of this work can be useful in the design of physiologically active derivatives
of pyridoxine and adamantane.

Abstract
Two series of novel pyridoxine-based azaheterocyclic analogs of feruloyl methane (Dehydrozingerone, DZG) were synthesized, and their biological activity against a panel of tumor and normal cell lines was evaluated in vitro. The most active compounds possessed expressed cytotoxic activity, which was comparable to cytotoxic activity of doxorubicin and significantly higher than that of DZG, and a remarkable selectivity for the studied cancer cell lines as compared to the normal cells. The leading compound and DZG initiated arrest of the cell cycle in the G2/M phase, preventing normal division and further transition of daughter cells to the G0/G1 phase. Similar to DZG, but with higher efficiency, the leading compound was able to inhibit migration activity and, therefore, invasiveness of tumor cells. It also increased concentration of reactive oxygen species in tumor cells, induced depolarization of mitochondrial membranes and initiated apoptosis accompanied by disruption of integrity of cytoplasmic cell membranes. By contrast to DZG, the leading compound did not possess antioxidant properties. The obtained data make the described chemotype a promising starting point for the development of new anticancer agents.

Abstract
The conformational properties of three pyridoxine derivatives were studied by 1 H dynamic NMR spectroscopy. Conformational exchange caused by a rotation of 2-nytrophenyl group around one single C-C bond, of 2,4-dinitrophenyl substituent around two single C-O bonds, and twist-twist transformations of the seven-membered ketal cycle was observed by NMR experiments at low temperatures. Meanwhile, the conformational exchange of the acetal ring remains fast in the NMR timescale even at 198 K. The energy barriers for all observed conformational exchange processes were determined by the lineshape analysis of dynamic NMR spectra. The activation barriers of the 2-nitrophenyl group rotation were almost the same for all studied compounds, about 40-41 kJ/mol. The energy barriers of the conformational exchange processes of the 2,4-nitrophenyl group and the ketal cycle increased significantly up to 10 kJ/mol in comparison with previously studied compounds with similar structure.

Abstract
A series of trans-6-phenylethenyl substituted pyridoxine derivatives, novel bioisosteric analogs of drugs based on trans-stilbene scaffold, were synthesized using the Wittig reaction of a bis-triphenylphosphonium pyridoxine derivative with various aromatic aldehydes. Two compounds demonstrated high activity against the estrogen-dependent MCF-7 (breast cancer) cell line with IC50 in the range of 1.9–7.9 µM and very good selectivity for other studied normal and tumor cells, including the estrogen receptor negative MDA-MB-231 breast cancer cells. The active compounds possessed an intense blue fluorescence, and this feature allowed us to effectively visualize them in cytoplasm and in nucleus. The obtained results make the described chemotype a promising starting point for the development of new anticancer agents for the therapy of estrogen-dependent malignancies.
