biological activities due to their structural relationship with chromones (benzopyrans), which are widely known as privileged scaffolds in medicinal chemistry. In this work, we report the synthesis of 35 thiochromone derivatives and the in vitro antileishmanial and cytotoxic activities. Compounds were tested against intracellular amastigotes of Leishmania panamensis and cytotoxic activity against human monocytes

by chemical synthesis and evaluated as inhibitors of cathepsinsL and B. The most promising inhibitors from this group are selective for cathepsinL and demonstrate IC50 values in the low nanomolar range. In nearly all cases, the thiochromanone sulfide analogues show superior inhibition of cathepsinL as compared to their corresponding thiochromanone sulfone derivatives. Without exception, the compounds
New convenient conditions for the Friedlander synthesis of quinolines are described. Polysubstitutedquinolines were readily prepared using chlorotrimethylsilane as a promoter and water-acceptor agent.
