Manipulation of galactolipid Fatty Acid composition with substituted pyridazinones.
The fatty acid composition of the major lipids of the chloroplast membranes, the mono- and digalactosyl diglycerides, can be definably altered with various substituted pyridazinones. Galactolipid fatty acid composition of wheat (Triticum aestivum L.) can be altered so that there is a decrease in linolenic acid accompanied by an increase in linoleic acid without a shift in the relative proportio...
متن کامل2-Arylacetamido-4-phenylamino-5-substituted pyridazinones as formyl peptide receptors agonists.
N-Formyl peptide receptors (FPRs: FPR1, FPR2, and FPR3) are G protein-coupled receptors that play key roles in modulating immune cells. FPRs represent potentially important therapeutic targets for the development of drugs that could enhance endogenous anti-inflammation systems associated with various pathologies, thereby reducing the progression of inflammatory conditions. Previously, we identi...
متن کاملSyntheses of highly functionalised 6-substituted pteridines.
Methods for the synthesis of polyfunctional 6-substituted pteridines from the corresponding 6-aldehydes are described. Alkene, ester, ketone, amide, cyano, oxime, bromo, methoxy and dihydroxy functional groups have all been introduced principally through improved methodologies for Wittig reactions using 2-thioalkyl-6-formylpteridines as substrates. Further modification of the alkenes derived fr...
متن کاملSynthesis of 1,5-diisopropyl substituted 6-oxoverdazyls.
1,5-Diisopropyl-6-oxo-verdazyl free radicals were synthesized via the condensation of BOC protected isopropyl hydrazine with phosgene, deprotection with aqueous HCl, condensation with aldehydes to form tetrazanes and finally oxidation to give the free radicals. The introduction of isopropyl groups results in free radicals that show greater solubility in a variety of solvents and are more stable...
متن کاملSynthesis and Antihypertensive Activity of Some Novel Pyridazinones
Four pyridazinones (2-5) were synthesized by the reaction of 3-benzoylpropionic acid with the corresponding hydrazines. These pyridazinones were further derivatized with appropriate aromatic aldehydes in the presence of piperidine to obtain the desired compounds (6-13). The chemical structures of the synthesized pyridazinones were elucidated on the basis of their spectral analysis (IR, 1H-NMR, ...
