A novel acetylcholinesterase (AChE) reactivator, a bispyridinium aldoxime named K048, was first synthesized in 2003. It is a promising antidote against tabun poisoning. Afterwards, other studies on several cholinesterases (ChE) of different species (humans, rats, etc.) and models (in vitro or in vivo) were conducted. We tested this oxime against nine different AChE inhibitors using in vitro tests on rat brain homogenate as sour Read More

A series of chrysin derivatives were prepared from 2-hydroxyacetophenone, 2,4-dihydroxyacetophenone, 2,4,6- trihydroxy- acetophenone, using modified Baker-Venkataraman transformation. Their anticancer activities in vitro were evaluated by the standard MTT method. The results of biological test showed that some of chrysin derivatives showed stronger anticancer activity than 5-fluorouracil.

Strong chelating ligands as oxodiacetate (oda) are model systems to study the process of metal trapping by living organisms. Vanadium compounds display interesting biological and pharmacological actions. In vertebrates, vanadium is stored mainly in bones. In the present study we report the effects of the complex of oda with vanadyl(IV) cation, VO(oda), on two osteoblast cell lines, one normal (MC3T3-E1) and the o Read More

A series of hetaryl imidazoles with VEGF receptors I and II inhibitory activities was subjected to QSAR analysis employing molecular descriptors calculated using QSAR software Dragon. Quantitative models of good statistical significance were formulated for both the activities through stepwise multiple linear regression using the method of least squares and the generated models were evaluated for predictive ability e Read More

Aldose Reductase (AR), the key enzyme of the polyol pathway catalyzes the reduction of glucose to sorbitol using nicotinamide adenine dinucleotide phosphate as an essential cofactor, has been demonstrated to play an important role in the pathogenesis of diabetic complications. Self Organizing Molecular Field Analysis (SOMFA), a novel threedimensional quantitative structure activity relationship (3D-QSAR) method has been used Read More

The present study investigated the treatment effects of the immunosuppressive agent, tacrolimus (FK506), on rats with acute necrotizing pancreatitis (ANP). Methods: We used the taurocholate-induced model of acute necrotizing pancreatitis (ANP) in rats that were divided into seven groups: The sham group included animals that underwent sham operations. The ANP group contained ANP rats induced by taurocholate Read More

A series of novel (±) 3-menthone semicarbazides (1-7) and thiosemicarbazides (8-14) were synthesized using an appropriate synthetic route and characterized by thin layer chromatography and spectral analysis. The anticonvulsant activity of synthesized compounds was established after intraperitoneal administration in three seizure models in mice which include maximal electroshock seizure (MES), subcutaneous pentyle Read More
