4-Thiazolidinone coumarin derivatives as two-component NS2B/NS3 DENV favivirus serine protease inhibitors: Synthesis, molecular docking, biological evaluation and structure - activity relationship studies

A series of novel 4-thiazolidinone inhibitors SKYa–SKYg, containing coumarin as a core structure were synthesized via facile and efficient method. The structures of the synthesized compounds were established by extensive spectroscopic studies (FT IR, 1D NMR, 2D NMR, LC–MS) and elemental analysis.
