The production of lipase from Acinetobacter calcoaceticus LP009, a bacterium isolated from raw milk, was found to be best induced by Tween-80 at 1.0% concentration. It was efficiently secreted, and only a minute amount of activity was detected at the cell surface and intracellularly. A. calcoaceticus LP009 lipase exhibited maximum activity at pH 7.0 and 50(More)
A lipase-producing bacterium, Acinetobacter calcoacetius LP009, was isolated from raw milk. The optimum conditions for growth and lipase production by A. calcoaceticus LP009 were 15 degrees C with shaking at 200 rpm in LB supplemented with 1.0% (v/v) Tween 80. The crude lipase was purified to homogeneous state by ultrafiltration and gel filtration(More)
Dill fruit (Anethum graveolens L.) is herbal medicine that was used in Thai traditional medicine. The objective of this study was to investigate the chemical compositions and antibacterial activity of essential oil of dill fruit that was cultivated in Thailand (Udon Thani province). Essential oils of dill fruits were obtained by hydrodistillation and steam(More)
We have broken old surviving dogmas and concepts used in computational chemistry and created an efficient in silico ADME-T pharmacological properties modeling and prediction toolbox for any xenobiotic. With the help of an innovative and pragmatic approach combining various in silico techniques, like molecular modeling, quantum chemistry and in-house(More)
The aim of the present study was to investigate the binding sites interactions and the selectivity of sarpogrelate to human 5-HT(2) receptor family (5-HT(2A), 5-HT(2B) and 5-HT(2C) receptor subtypes) using molecular modeling. Rhodopsin (RH) crystal structures were used as template to build structural models of the human serotonin-2A and -2C receptors(More)
Serotonin (5-hydroxytryptamine, 5-HT), a monoamine neurotransmitter of the central nervous and peripheral systems (CNS), plays a critical role in a wide variety of physiological and behavioral processes. In the serotonergic system, deregulation of the tightly controlled extracellular concentration of 5-HT appears to be at the origin of a host of metabolic(More)
A series of prenylated resveratrol derivatives were designed, semisynthesized and biologically evaluated for inhibition of β-secretase (BACE1) and amyloid-β (Aβ) aggregation as well as free radical scavenging and neuroprotective and neuritogenic activities, as potential novel multifunctional agents against Alzheimer’s disease (AD). The results showed that(More)
The serotonergic system plays a critical role in a wide variety of physiological and behavioral processes. Dysregulation of the tightly controlled extracellular concentration of serotonin (5-hydroxytryptamine, 5-HT) appears to be at the origin of a host of metabolic and psychiatric disorders. Since the plasma membrane 5-HT transporter (SERT) is the major(More)
The geometric description of pharmacophores suffers from approximations. No consensus has been clearly established, despite the increasing interest in using pharmacophores in drug design and in patent applications. We therefore propose an original definition of a pharmacophore using spherical coordinates. These coordinates give a precise description of each(More)
