Organophosphorus compounds have been used as pesticides and as chemical warfare nerve agents. The mechanism of toxicity of organophosphorus compounds is the inhibition of acetylcholinesterase, which results in accumulation of acetylcholine and the continued stimulation of acetylcholine receptors. Therefore, they are also called anticholinesterase agents.(More)
We have constructed a mixed dioleoylphosphatidylcholine (DOPC) and dioleoylphosphatidylglycerol bilayer (DOPG) bilayer utilizing MD simulations. The aim was to develop an explicit molecular model of biological membranes as a complementary technique to neutron diffraction studies that are well established within the group. A monolayer was constructed by(More)
The results of vasorespiratory studies in rats anaesthetised with pentobarbital show that (+/-) cannabidiol, a cannabinoid that lacks psychotropic actions and is inactive at cannabinoid (CB) receptors, does not affect respiration or blood pressure when injected (1-2000 microg; 3.2-6360 nmol i.a.). Cannabidiol in doses up to 2 mg (6360 nmol) i.a. or i.v. did(More)
Adenosine diphosphate ribosylation factor-1 (ARF1) is activated by cell membrane binding of a self-folding N-terminal domain. We have previously presented four possible conformations of the membrane bound, human ARF1 N-terminal peptide in planar lipid bilayers of DOPC and DOPG (7:3 molar ratio), determined from lamellar neutron diffraction and circular(More)
Human islet amyloid polypeptide (hIAPP) forms amyloid deposits in non-insulin-dependent diabetes mellitus (NIDDM). Pre-fibrillar hIAPP oligomers (in contrast to monomeric IAPP or mature fibrils) increase membrane permeability, suggesting an important role in the disease. In the first structural study of membrane-associated hIAPP, lamellar neutron(More)
The effect of myristoylation on the 15-amino-acid peptide from the membrane-binding N-terminus of ADP ribosylation factor 1 (ARF1) was studied using neutron diffraction and circular dichroism. A previous study on the non-acylated form indicated that the peptide lies parallel to the membrane, at a shallow depth and in the vicinity of the phosphorylcholine(More)
Temperature-scan X-ray scattering was used to study the effect of the fusion peptide of simian immunodeficiency virus (SIV) on the lipid polymorphism of N-methylated dioleoylphosphatidylethanolamine (DOPE-Me), in the presence and absence of one or both of the fusion inhibitors carbobenzoxy-D-phenylalanine-L-phenylalanine-glycine and(More)
