The combination of circular dichroism with laser mass spectrometry via the measurement ion yields is a powerful tool in chiral recognition, but measured anisotropies are generally weak. method presented this contribution reduces error significantly. A common path optical setup generates pair counter-rotating foci interaction region time-of-flight spectrometer. As space focus condition fulfilled...

Bis diacetylpyridine derivative (1) was prepared and reacted with different halo-compounds, namely: epichlorohydrine and dichloroethyl ethyl ether to give 2a,b, respectively, and reacted with morpholine and piperidine to afford Mannich products 3a,b, successively. Compound 4 was synthesized by reaction of 1 with potassium thiocyanate. Reaction of 4 with 4-chlorobenzaldehyde, glucose and phthali...

Curcumin is known could inhibit the activation of NF-kB, which is important in osteoclast differentiation and activation. The aims of this research were to conduct the effect of curcumin and Pentagamavunon-0 or PGV-0 [2,5-bis-(4’-hydroxy-3’methoxybenzylidene)-cyclopentanone], on osteoclast differentiation and apoptosis. Osteoclast differentiation was carried out using Osteoclast Differentiation...

Over 40 new compounds were isolated and identified from a cold-finger molecular distillate obtained from a dichloromethane extract of a lactose-casein browning system, in connection with studies on off-flavor development in dairy products. These compounds consist of 15 C-5 to C-14 furanics, five pyrazines, three pyrroles, three lactones, 2-acetylpyridine, acrolein, cyclopentanone, 2-methyltetra...
