Synthesis and thermophysical properties of ionic liquids: Cyclopropyl moieties versus olefins as Tm-reducing elements in lipid-inspired ionic liquids

Cyclopropyl moieties embedded in the long aliphatic side chains of imidazolium-type ionic liquids are shown to be highly effective in lowering the Tm of such materials relative to counterparts bearing linear, saturated side chains. While not as efficient as olefins in bringing about this effect, ILs incorporating side-chain cyclopropanated modules are likely to be more resistant to aerobic degradation than those employing the former.

The newly synthesized linoleic acid derivative FR236924 induces a long-lasting facilitation of hippocampal neurotransmission by targeting nicotinic acetylcholine receptors

The newly synthesized linoleic acid derivative, FR236924, induces a long-lasting facilitation of hippocampal neurotransmission based on a persistent enhancement in the activity of presynaptic nicotinic ACh receptors via a PKC pathway and the ensuing increase in glutamate release, not only in vitro but in vivo at a low dosage (2 mg/kg, ip), which suggested the possibility of its use as a promising anti-dementia drug.

Ultrasound in Lipids. Furan Formation under Ultrasonic assisted Simmons-Smith Reaction and the Effect of Cadmium and Copper as Zinc Replacers

Methyl 12-oxo-octadec-9-cis-enoate gave methyl 9,12-epoxyoctadeca-9,11-dienoate when treated with zinc or cadmium in the presence of di-iodomethane and 1,2-dimethoxyethane under concomitant ultrasonic irradiation, while under similar conditions copper caused cyclopropanation across the ethylenic bond in methyl oleate and ricinoleate.
