BACKGROUND AND OBJECTIVES Alcohol abuse complicates treatment of HIV disease and is linked to poor outcomes. Alcohol pharmacotherapies, including disulfiram (DIS), are infrequently utilized in co-occurring HIV and alcohol use disorders possibly related to concerns about drug interactions between antiretroviral (ARV) medications and DIS. METHOD This pharmacokinetics study (n=40) examined the e...

Courtship behavior in several pyralid species is associated with the exposure to male hair pencils (HPs) or special scales that released volatile compounds. HP chemicals induce conspecific female and/or male behaviors and are therefore qualified as male pheromones. Preliminary observation on the coffee berry moth (CBM), Prophantis smaragdina Butler (Lepidoptera: Crambidae: Spilomelinae) mating ...

Regioselective addition of aryl lithium to commercially available (S)-(+)-propylene oxide provides the corresponding (S)-aryl-2-propanol. The (R)-amphetamine is obtained by conversion of the alcohol to the tosylate followed by azide displacement and hydrogenation. Mitsunobu conversion of the alcohol to the (R)-bromide followed by azide displacement and hydrogenation affords the (S)-amphetamine....

Methyl sterculate was rearranged by use of 0.5% of rhodium catalyst to isomeric conjugated diene fatty acid methyl esters containing both methyleneand methyl-branched isomers. The rearranged products were hydrogenated directly to saturated, methyl-substituted, branched-chain fatty acid methyl esters with the methyl substituent at one of the positions formerly occupied by the cyclopropenoid ring...

The catalyst palladium/2,9-CD3-phenanthroline has a 1.8 times higher turnover number than its non-deuterated counterpart in the aerobic alcohol oxidation of methyl glucoside and allows the regioselective oxidation with dioxygen as the terminal oxidant.

Furfuryl alcohol, formed by acid- and heat-induced dehydration from pentoses, is found in many foodstuffs. It induced renal tubule neoplasms in male B6C3F1 mice and nasal neoplasms in male F344/N rats in a study of the National Toxicology Program (NTP). However, furfuryl alcohol was negative in the standard Ames test and in a battery of in vivo mutagenicity tests. Here, we show that furfuryl al...

A method to determine the absolute configuration of 2,3-epoxy-2-methylbutanoate ester residues in natural products is presented, based on (i) the reduction of the ester function to yield a 2-methyl-1,2-butanediol, (ii) esterification of the obtained primary alcohol with either (R)-(+)- or (S)-(-)-Mosher's acid to afford the corresponding Mosher's ester, and (iii) 1H-NMR spectral comparison of t...

In this study, GC-MS and sensory evaluation were used to analyze the volatile components of fruits 2 white M. rubra purple . Meanwhile, their relationship among each other massion pine ( Pinus massoniana ) detected. The test results showed that, there 60 organic compounds (VOCs) in 8 categories, including aldehydes, acids, ketones, alcohols, esters, phenols, olefins alkanes, found four cultivar...
