The anthelminthic activity of the essential oil (EO) of Piper aduncum L. was tested in vitro on eggs and larvae of resistant (Embrapa2010) and susceptible (McMaster) isolates of Haemonchus contortus. The EO was obtained by steam distillation and its components identified by chromatography. EO concentrations of 12.5 to 0.02 mg/mL were used in the egg hatch test (EHT) and concentrations of 3.12 t...

The chemical composition of the volatile metabolites of Crithmum maritimum harvested from several geographic localities along the Mediterranean coasts was studied by GC and GC-MSD. The major oil constituents were found to be dillapiole, gamma-terpinene, sabinene, limonene and beta-phellandrene. The Western populations were richer in dillapiole, whereas the Southern collections were characterize...

kcnk2 was previously shown to regulate immune-cell trafficking into the central nervous system (cns). kcnk2-/- mice demonstrated a more severe disease course in experimental autoimmune encephalomyelitis, an animal model of multiple sclerosis, due to an increased immune-cell migration into the cns. an upregulation of the cellular adhesion molecules icam1 and vcam1 on brain endothelial cells in k...

The aim of the present in vivo study was to determine whether a benzodioxan derivative MKC-242, (S)-5-[3-[(1,4-benzodioxan-2-ylmethyl)amino]propoxy]-1,3-benzodioxole hydrochloride, possesses an agonistic activity at postsynaptic serotonin (5-HT)1A receptors in the rat hippocampus when administered systemically. We examined the effects of acute administrations of MKC-242 on the firing activities...

Bioassay-guided fractionation was used to isolate the lignan polygamain as the microtubule-active constituent in the crude extract of the Mountain torchwood, Amyris madrensis. Similar to the effects of the crude plant extract, polygamain caused dose-dependent loss of cellular microtubules and the formation of aberrant mitotic spindles that led to G(2)/M arrest. Polygamain has potent antiprolife...

This article will present the factual material that up to 1972, MDMA was entered with the phenethylamine exists in the literature representing the results of laboraname. Since then, the heterocyclic term benzodioxole-5i tory studies and scientific experimentation with ethanamine has been the root name. The common abbremethylenedioxymethamphetamine or MDMA, the comviation MDMA is based on the co...
