Design, synthesis, and 5-lipoxygenase-inhibiting properties of 1-thio-substituted butadienes
摘要:
The synthesis of novel 1-thio-substituted butadienes, designed as mechanism-based 5-lipoxygenase inhibitors, is described. The structure of these compounds closely resembles a proposed high-energy intermediate during the lipoxygenation of arachidonic acid. They demonstrate 5-lipoxygenase inhibition in vitro and in vivo. The most potent compound is 15a with an IC50 of 1.8 microM in vitro. LTC4 release was inhibited by 80% after intraperitoneal administration of 15c at a dose of 2 mg/kg.

Palladium nanoparticles<i>in situ</i>synthesized on<i>Cyclea barbata</i>pectin as a heterogeneous catalyst for Heck coupling in water, the reduction of nitrophenols and alkynes
used as a catalyst for the conversion of alkynes into cis-alkenes with KOH/DMF as a hydrogenation source. The reaction was also utilized effectively for the synthesis of sexpheromones, including Plutella xylostella ((Z)-11-hexadecen-1-yl acetate) and Cylas formicarius ((Z)-3-dodecen-1-yl(E)-2-butenoate) with the total yields of 70% and 68%, respectively. Therefore, PdNPs supported on C. barbata pectin
