The Pyridine Nucleotide Cycle and Its Role in the Biosynthesis of Ricinine by Ricinus communis

The pyridine moieties of the pyridine nucleotides, nicotinic acid mononucleotide, nicotinic acid adenine dinucleotide, and nicotinamide adenine dinucleotide, were shown to be incorporated into ricinine by Ricinus communis L. with an efficiency comparable to that of quinolinic acid, nicotinic acid, and nicotinamide, which had been established previously as being efficient precursors of this alka...

Activation of the de novo pathway for pyridine nucleotide biosynthesis prior to ricinine biosynthesis in castor beans.

The ricinine content of etiolated seedlings of Ricinus communis increased nearly 12-fold over a 4-day period. In plants quinolinic acid is an intermediate in the de novo pathway for the synthesis of pyridine nucleotides. The only known enzyme in the de novo pathway for pyridine nucleotide biosynthesis, quinolinic acid phosphoribosyltransferase, increased 6-fold in activity over a 4-day period w...

Biosynthesis of the pyridine ring of ricinine.

The most widely distributed substituted pyridine compounds in living systems are the pyridine nucleotides. The nicotinamide moiety (Fig. 1, I) of these compounds arises from the indole nucleus of tryptophan in animals, (1, 2) and Neurospora (3, 4), but not in higher plants (5-7) and certain bacteria (8). Pyridine compounds which might be used to study the biosynthesis of the pyridine nucleus ar...

Activity Guided Isolation Of Anti-Inflammatory Compound/Fraction From Root Of Ricinus communis Linn

In Indian system of medicines, root of Ricinus communis Linn. is used to treat inflammation and liver disorders. In present study, the ME of root was prepared by soxhlet method. ME was fractionated into four fractions; explicitly, chloroform, ethyl acetate, n-butanol, and remaining aqueous fraction. The n-butanol fraction, having showed significant inhibition of inflammation, was subjected to f...
