Fourteen novel bis-carboxamide derivatives of 4-pyrones were designed and synthesized via Ugi four-componentreactions of 4-pyrone carbaldehydes, aromatic amines, isocyanides and carboxylic acids. The cytotoxic activity of synthesized derivatives was evaluated against LS180, MCF-7 and HL-60 cell lines using MTT reduction assay. Synthesized compounds demonstrated strong cytotoxic potential in HL-60 cell line
