the traditional extraction method was used to evaluate the antioxidant properties of nettle leaves in soybean oil. also the effects of three different solvents (water, 80% methanol and chloroform) on the extraction content of phenolic and flavonoid compounds from nettle leaves were examined. water extract had the highest extraction yield, and chloroform extract had the highest extraction conten...

Primary cultures of Friend virus-infected spleen cells have a marked increase of hemoglobin synthesis in vitro in the absence of added erythropoietin. Seven sulfhydryl compounds were tested in this liquid culture system and all were found to enhance hemoglobin synthesis in a dose-dependent fashion. An optimum concentration for each compound was determined beyond which inhibition was observed. T...

materials and methods twelve natural compounds jaceosidin, withaferin a, curcumin, epigallocatechin-3-gallate (egcg), artemisinin, gingerol, ursolic acid, ferulic acid, berberin, silymarin, resveratrol, and indol-3-carbinol were docked against e6 and e7 oncoproteins of high-risk hpv types 16 and 18 using a protein-ligand docking software called autodock4.2. results out of these 12 natural compo...

a novel series of azolylalkylthio, -sulfoxy, and-sulfonyl compounds was designed, synthesized, and evaluated for antipicornaviral activity. two compounds (4i and 4 1) exhibited significant activity against various serotypes of human rhinovirus (hrv). it was found that incorporation of hydrophobic azoles such as 3-methylisoxazole or 4-methylthiazole led to increased activity. in addition, activi...

the present study aimed to use a method for the synthesis of some 3, 4-dihydropyrimidin-2-(1h) - ones/thiones. the study tried to answer the question whether this reaction can be performed without solvent and with new catalyst or not. to find answer to the question, we described a novel protocol for the efficient synthesis of 3, 4-dihydropyrimidin-2-(1h)-one derivatives using aromatic aldehyde,...

it   was   recently   demonstrated   that   5-(5-nitrofuran-2-yl)-1,   3,   4-thiadiazoles   with piperazinyl-linked benzamidine substituents are effective in vitro against leishmania major. following on this evidence, we used colorimetric assay of acid phosphatase activity in the promastigotes  as  an  indicator  for  cell  viability.  also  we  studied  the  effect  of  these compounds on ind...

extensive research in the last decade has defined that most chronic diseases display dysregulation of multiple cell signaling pathways that have been linked to inflammation. neuroinflammation is reaction of living nervous tissue to injury. it may be initiated in response to neurological disease. including infection, traumatic brain injury, toxic metabolites and autoimmunity. the natural compoun...

Epilepsy affects about 1% of the world's population. Due to the fact all antiepileptic drugs (AEDs) have some undesirable side effects and about 30% of epileptic patients are not seizure-free with the existing AEDs, there is still an urgent need for the development of more effective and safer AEDs. Based on our research work on antiepileptic compounds and other references in recent years, this ...
