Web26. sep 2024 · Unlike distillation, the reflux process is used in chemistry to accelerate a specific reaction thermally. This is done by conducting it in a controlled high temperature. The role of a condenser here is to cool down the generated vapours and convert them back into the liquid form. The liquid component is then sent back to the boiler. WebDesign Strategy. Like our previous design, we attempted to connect the 3,4-dihydro-2(1H)-quinolinone core with dithiocarbamate moiety through different lengths of the carbon chain linker to design novel multifunctional compounds for AD treatment (). 3,4-dihydro-2(1H)-quinolinone core was chosen to inhibit the MAO-B and interact with the PAS of AChE..
