In the 1980s, authors developed enzyme immunoassay (EIA) system for mouse nerve growth factor (NGF) to clarify its important physiological roles. Our EIA was a new and powerful tool measurement of extremely low levels NGF in vitro vivo, it contributed investigation into regulatory mechanism synthesis. After that, we demonstrated that compounds with molecular weight, such as 4-methylcatechol, wh...
of an internal rotation; the greater time for the carbon compound indicates some frictional resistance to rotation. Both dimethoxy compounds have similar relaxation times, as also have the tetramethoxy compounds. The greater size and substantially higher dipole moments of the silicon compounds, however, should produce a proportionately greater contribution from the molecular tumbling motion. Th...
This study aimed to determine the effect of Volatile Organic Compounds (VOCs) on some pathogens, these VOCs were emitted during interactions of barley with Fusarium culmorum Schltdl and/or Cochliobolus sativus Shoemaker, two common root rot pathogens. Our work shows that two organic esters: methyl propanoate (MP) and methyl prop-2-enoate (MA) significantly reduced the development of fungi in vi...
A general and direct strategy for the synthesis of chiral spiro-aziridine oxindoles has been developed via an aza-Corey-Chaykovsky reaction of isatin-derived N-tert-butanesulfinyl ketimines with excellent selectivity (dr = 98:2 to >99:1). The method is explored for the synthesis of chiral 3-substituted spiro-aziridine oxindoles with high (2S,3S)-selectivity over (2S,3R).
