Author is Nija, B.; Rasheed, Arun; Kottaimuthu, A..

The current research work investigate the neuronal pathway associated with NSAIDs that lead to the reduction in the initiation and progression of neurodegenerative diseases such as Alzheimer’s disease, Parkinsonism, etc. This research was developed amino acid prodrugs of the active enantiomer of ibuprofen, (+)-IBN and checks the pharmacol. effects, neuroprotective effect, anti inflammatory effect and anti-ulcerogenic effect. The treatment using (+)-IBN reduced the action of micoglia and the release of cytokine especially TNFα that are mainly involved in the neurodegenerative process. (+)- IBN reduced the deposition of soluble beta amyloid plaque by inhibiting the amyloid precursor protein, beta-secretase 1 and also enhancing the degradation process of beta amyloid via induction of insulin degrading enzyme. (+)-IBN also showed the property that the reduction in the TAU misfolding process. Therefore, the synthesized (+)-IBN amino acid prodrugs treatment effectively produce neuroprotective action, both restoring memory realed risk factors and reversing multiple brain neuropathol. hallmarks. The current research study developed the three amino acid prodrugs of (+)-ibuprofen by conjugating with L-Ph alanine, L-tryptophan and L-tyrosine also the physico-chem. characterization and spectral characterization was done. This study modify the carboxylic acid functional group present in the NSAIDs that lead to the formation of prodrugs with enhanced anti-inflammatory activity, reduced side effects and protective effect against neurodegenerative processes.

Activity of phospholene derivatives as catalysts for polymerization of diphenylmethane diisocyanate (I) [26447-40-5] increased with increasing electron-donor activity of the substituent on the P atom of the catalyst. Kinetics data showed a dependence of the catalytic activity of phospholene derivatives on their structure, and the highest activity showed oxides of tertiary phosphines, whereas introduction of O and Cl in the ester radical decreased the polymerization rate. A nucleophilic character of the catalyst in the formation of carbodiimide-containing polymers was suggested. The highest polymerization rate of I was observed in the presence of 1-oxo-1-ethyl-3-methyl-2-phospholene (II) [56255-62-0], 1-oxo-1,3-dimethyl-3-phospholene [15450-79-0] and 1-oxo-3-methyl-1-phenyl-2-phospholene [707-61-9] as catalysts.
