Studies with knockout mice have indicated that the only isoform of phosphoinositide 3-kinase (PI3K) functioning in the oxidative burst of mouse neutrophils in response to heterotrimeric guanine nucleotide-binding protein-coupled receptor (GPCR) agonists is a class-IB PI3K, p110γ. In the present study, we observed that the cells from p110γ(-/-) mice gain ...

The chemistry of beer flavor instability remains shrouded in mystery, despite decades of extensive research. It is, however, certain that aldehydes play a crucial role because their concentration increase coincides with the appearance and intensity of "aged flavors". Several pathways give rise to a variety of key flavor-active aldehydes during ...

Pause and play: Dihydrooxazine oxides are stable intermediates that are protonated directly, without the intermediacy of the zwitterions, in organocatalytic Michael additions of aldehydes and nitroalkenes (see scheme, R=alkyl). Protonation of these species explains both the role of the acid co-catalyst in these reactions, and the observed stereochemistry when the ...
