Finally, the computational insights are experimentally validated with double-headed pyridine analogues.

No pyridine N-oxidation or alpha-hydroxylation were observed in these preparations.

IR spectra suggest that the pyridine nitrogen is not coordinating.

And Professor See, the eminent French physician, believes that the pyridine is the relieving agent.

We demonstrate a twisted conformation about the pyridine-piperidine bond of 9 by small-molecule X-ray crystallography.

This process is reversible upon addition of pyridine.

As already stated, both series occur in coal-tar and the pyridine series also more abundantly in bone-oil.

The results obtained displayed many more cross-ring fragmentation of the pyrimidine ring compared to the pyridine ring.

These enzymes share a conserved FAD-binding domain but lack a recognizable fold for binding the pyridine nucleotide.

On the other hand, a cigar produces but little pyridine, but more of the less active collidine.

These results demonstrate that pyridine-N-oxidation is a relatively minor detoxification pathway of NNK and NNAL in humans.

NAD is a pyridine nucleotide that is involved in cell metabolism and signaling of plant growth and stress.

A. Wyschnegradsky, and afterwards W. Konigs, expressed the opinion that the alkaloids were derivatives of pyridine or quinoline.

Perturbation of folate homeostasis can alter the pyridine nucleotide redox ratios that are important regulators of cellular metabolism.

This pyridine to which reference has just been made has lately been brought forward as a remedy for asthma.

Adjacent mononuclear units are overlapped through pi-pi stacking of pyridine rings to give a 2D sheet with a triangular channel.
