The β-diketiminatolead(II)-amido and -anilido complexes, [(BDI)Pb(NRR')] (BDI = [{N(2,6-iPr2C6H3)C(Me)}2CH]; NRR' = NH(2,6-iPr2C6H3), N(iPr)2), react at the amido/anilido nitrogen atom with simple saturated electrophiles such as methyltriflate. Addition of unsaturated electrophiles to these complexes either results in the formation of a complex mixture of products, or in the case of phenylisocy...

Chronic hepatitis increases the risk of hepatocellular carcinoma (HCC). To test whether circulating proteins reflect hepatic carcinogenesis, sera from patients and controls were albumin depleted, enriched for glycoproteins, digested with trypsin, and subjected to reverse phase chromatography and tandem mass spectrometry. Alpha-fetoprotein enhancer binding protein (AFPebp), a tumor suppressor, w...

This work described a simple and efficient synthesis of dialkyl 3-(alkylamino)-1-aryl-1H-pyrazole-4,5-dicarboxylates via a three component reaction between arylhydrazine, alkylisocyanid and dialkylacetylenedicarboxylates in the presence of phenylisocyanate and α-Fe2O3 nanoparticles. Eco friendly, solvent-free conditions, excellent yields, and short reaction times, inexpensive and readily availa...

A new series of 3-substituted (methyl, ethyl or phenyl)-3H-quinazolin-4-one derivatives (4a-l) were synthesized through condensation reaction of their potassium salts (3a-l) with methyl, ethyl and phenylisocyanate. The newly synthesized derivatives (4a-l) were evaluated for anticonvulsant activity. It was found that these compounds showed the highest anticonvulsant activity at low doses (50-100...
