have already been introduced. We have applied the olefin metathesis for the preparation of cysteine-targeted insecticides in high yields. The prepared compounds with either a succinimide or maleimide moiety were evaluated on Anopheles gambiae and human acetylcholinesterase with relatively high irreversible inhibition of both enzymes but poor selectivity. The concept of cysteine binding was not proved

The catalytic activity of macrocyclic phenanthroline-CuI complexes was utilized to synthesize [2]catenanes by intramolecular Sonogashira-type reaction. The high reactivity of the acyclic starting material was critical to synthesize the [2]catenane in acceptable yields. The relationship between the yield of the [2]catenane and the structure of the starting materials was disclosed.

eicosanes carrying phosphate headgroups and readily derivatizable thiol, maleimido, and activated carboxylic ester moieties were prepared. The C20-backbone of these molecules was assembled by a halopolycarbonhomologation from 1,8-dichlorooctane and 1,6-dibromohexane. 20-Mercapto- and 20-maleimido-icosylphosphates were synthesized via omega-bromo di-t-butyl protected icosylphosphate while 20-phosphonooxy-icosanoic

20 methylene spacers did not show photoinduced solid-to-liquid transitions. Azopolymers with 6 or 12 methylene spacers showed photoinduced solid-to-liquid transitions. This study demonstrates that spacers are essential for azopolymers with photoinducedreversible solid-to-liquid transitions, and thus, gives an insight into how to design azopolymers for photoinduced healing and processing.
Cytochrome c was found to undergo electron transfer reactions at a gold electrode modified with a Langmuir-Blodgett monolayer of 20-mercaptoeicosane-1-ol/dioleoyl-L-α-phosphatidylcholine (molar ratio, 1/20). The stability of the monolayer and the adsorption behavior of cytochrome c to the monolayer was also examined.
研究发现,细胞色素 c 在由 20-巯基-1-二十烷醇/二油酰-L-α-磷脂酰胆碱(摩尔比为 1/20)的 Langmuir-Blodgett 单层修饰的金电极上发生电子转移反应。此外,还考察了单层的稳定性以及细胞色素 c 在单层上的吸附行为。
