Minimal structural requirements of alkyl gamma-lactones capable of antagonizing the cocaine-induced motility decrease in planarians

We recently reported that the natural cyclic lactone, parthenolide, and related analogs prevent the expression of behavioral effects induced by cocaine in planarians and that parthenolide’s gamma-lactone ring is required for this effect. In the present work, we tested a series of alkyl gamma-lactones with varying chain length (1-8 carbons) to determine their ability to antagonize the planarian motility decrease induced by 200 muM cocaine. Alkyl lactones with up to a 4-carbon alkyl chain did not affect planarian motility or antagonized the cocaine-induced motility decrease; only the compound gamma-nonalactone (a gamma-lactone with a 5-carbon chain) was able to prevent the cocaine-induced behavioral patterns, while alkyl lactones with longer carbon chains failed to prevent the cocaine-induced effects. Thus, we conclude that the optimal structural features of this family of compounds to antagonize cocaine’s effect in this experimental system is a gamma-lactone ring with at a 5-carbon long functional group.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 105-21-5, help many people in the next few years.Safety of Gamma-heptalactone

Synthesis of new (3-aminopyrrolidin-3-yl)phosphonic acid – A cucurbitine analogue – and (3-aminotetrahydrothiophen-3-yl)phosphonic acid via phosphite addition to heterocyclic hydrazones

Hydrazones were prepared by condensation of carbocyclic and heterocyclic ketones with benzoyl- and tosylhydrazines. These hydrazones underwent nucleophilic addition with phosphite to provide efficiently (3- hydrazinopyrrolidin-3-yl)-, (3-hydrazinotetrahydrothiophen-3-yl)-, (3-hydrazinotetrahydrofuran-3-yl)-, and (1-hydrazinocyclopentyl)phosphonates. Cleavage of the hydrazine N-N bonds followed by acidic hydrolysis of the phosphonate functions of the (3-aminoheterocyclopentyl)phosphonates gave the new (3-aminopyrrolidin-3-yl)- and (3-aminotetrahydrothiophen-3-yl)phosphonic acids. This synthesis was achieved in a four-step sequence from the appropriate ketones. Georg Thieme Verlag Stuttgart.

Aroma quality improvement of Chardonnay white wine by fermentation and ageing in barrique on lees

The aroma quality of Chardonnay white wines as affected by different processing conditions is assessed in this work. Three technologies were tested: fermentation and ageing in stainless steel, fermentation and ageing in barrique on lees, fermentation and ageing in barrique on lees after partial removal of lees after fermentation. Volatile profile by means of gas-chromatography coupled to mass spectrometry and sensory analysis by means of descriptive and triangle tests were evaluated in order to discriminate between the tested wines. The ageing on lees, most without raking, led to an enhancement of flavor active compounds, such as lactones, terpenoids, ketones, aldehydes and esters, and to a likely related improvement of taste. Change in odor with respect to traditionally made wine was not easily established, because the presence of lees attenuated the impact of wood, which is generally strong, on the aroma balance of wine.
