The hydrolytic enzymes acetyl- and butyryl-cholinesterase, the cell adhesion molecules neuroligins, and the hormonogenic macromolecule thyroglobulin are a few of the many members of the α/β hydrolase fold superfamily of proteins. Despite their distinctive functions, their canonical subunits, with a molecular surface area of ~20,000 Ų, they share binding patches and determinants for forming hom...

Esenbeckia leiocarpa Engl. (Rutaceae), popularly known as guarantã, goiabeira, is a native tree from Brazil. Bioactivity-guided fractionation of the ethanol stems extract afforded the isolation of six alkaloids: leiokinine A, leptomerine, kokusaginine, skimmianine, maculine and flindersiamine. All isolated compounds were tested for acetyl cholinesterase inhibition, in vitro and displayed antich...

The aim of present study is to investigate neuroprotective and nootropic activity of Petroleum Ether Extract of Carica papaya seeds (PEECPS) on diabetic induced cognitive decline rats. Rectangular maze and morris water maze models were used to evaluate nootropic activity and neuroprotective effects were studied by estimating acetyl cholinesterase (AchE), malondialdehyde (MDA), superoxide dismut...

Phytochemicals found in extracts obtained from plants are very important bioactive constituents. In this study, phytochemicals extract content Celtis tournefortii .Lam. tree (CT) leaves were determined by a LC-MS method. The constituents with the major concentrations was rutin (2479.89 µg ml-1), coumarin (1241.68 biochanin A (1026.42 shikimic acid (477.32 chlorogenic (300.76 ml-1). suppressive ...

Ayurveda, Unani, Siddha and Homeopathy medicines are the major systems of indigenous medicines. Among these systems, Ayurveda is most trusted and widely practiced in India. Acorus calamus Roots and rhizomes have been used in Indian system of traditional medicine for hundreds of years and it is highly valued as a rejuvenator for the brain and nervous system and as a remedy for digestive disorder...

Type A botulinum toxin was studied for its ability to inhibit the action of acetyl-cholinesterase. The chromogenic substrate, indophenyl acetate, was used for assay of enzyme activity. Inhibition of enzyme function was detected through use of both 6.6 x 10(-6) mg (20 ld(50)) and 6.6 x 10(-10) mg (2 x 10(-3)ld(50)) of type A botulinal toxin. Control assays were performed by use of both homologou...

• First time HPTLC- Fusarium avenaceum bioassay using mycelium suspension HPTLC-EDA combined with HPTLC-DART-HRMS and HPTLC-ESI-HRMS Preparative-scale isolation of eight multipotent clerodane diterpenes cholinesterase, glucosidase, amylase microbial inhibitory potential compounds Giant goldenrod ( Solidago gigantea Ait.) root extract was screened for bioactive by high-performance thin-layer chr...

Megakaryocytopoiesis and platelet production can be assessed with reasonable accuracy by quantitative and functional analyses of circulating platelets. The evaluation of megakaryocytopoiesis in culture has remained unsatisfactory, particularly because platelet production is rarely observed. In mouse culture systems, megakaryocytes have been identified almost entirely by measurements of acetyl c...
