Anticancer activity of natural and synthetic acetylenic lipids
Lipids, 2006AbstractThis review is a comprehensive survey of acetylenic lipids and their derivatives, obtained from living organisms, that have anticancer activity. Acetylenic metabolites belong to a class of molecules containing triple bond(s). They are found in plants, fungi, microorganisms, and marine invertebrates.

INTERACTION OF ELECTRIC EEL ACETYLCHOLINESTERASE WITH NATURAL AND SYNTHETIC LIPIDS
Neurochemistry International, 1980Interaction of purified molecular forms of electric eel acetylcholinesterase with liposomes prepared from a number of natural and synthetic lipids was demonstrated by a flotation gradient technique. 14S+18S 'tailed' AChE interacted with certain phospholipids at both high and low ionic strength, and with several others only at low ionic strength.

Synthetic Lipid- and Lipoprotein Membranes
1971By superimposing monomolecular layers it is possible to arrange molecules in a specific planned order. This method of obtaining simple organized systems of molecules should be of interest to the membranologist as a possible means of building models of biological structures. The possibility of molecular contact between a synthetic monolayer assembly and

Synthetic functional π-stack architecture in lipid bilayers
Org. Biomol. Chem., 2006Neglected until recently, pi-stack architecture is rapidly emerging as a powerful strategy to create function in lipid bilayer membranes. Recent reports describe supramolecular rosettes acting as hosts of intercalating guests, to assemble in bilayer membranes and, in the case of stacked guanosine and folate quartets, to form ion channels.

Synthetic and modified glycerides: effects on plasma lipids
Current Opinion in Lipidology, 2001It has been suggested that the molecular species or structure of the triglyceride, i.e. not only what fatty acids are present but also their relative order in the sn1, 2, or 3 position on the triglyceride, can influence the metabolism of the triglyceride and its fatty acids, including lipoprotein metabolism.

Fusion of lipid bilayers induced by synthetic lipids and peptides
2009The fusion-inducing properties of three different synthetic lipid derivatives were investigated in model membranes. The results are discussed in terms of membrane destabilization caused by the formation of non-bilayer lipid structures following charge neutralization of the fusogenic components. First, studies on the fusion of large unilamellar vesicles

Low abundances of synthetics lipids in phantoms
SPIE Proceedings, 2012Phantoms simulate optical characteristics of tissues. Phantoms use to mimic light distributions in living tissue. Several Phantoms compositions made of silicone, polyester, polyurethane, and epoxy resin have been described in the literature. These kinds of phantoms have the problem of long time preservation.

Bilayer-Forming Synthetic Lipids: Drugs or Carriers?
Current Medicinal Chemistry, 2003Since their introduction as bilayer-forming synthetic compounds in the eighties, dioctadecyldimethylammonium (DODA) and dihexadecylphosphate (DHP) salts have found many uses in strategic, applied areas. In particular, DODA chloride or bromide vesicles interacted with negatively charged prokaryotic or eukaryotic cells, yielding adsorption isotherms of ...
