Pyridazinone-based derivatives as anticancer agents endowed with anti-microbial activity: molecular design, synthesis, and biological investigation.

Cancer patients undergoing chemotherapy are highly susceptible to infections owing to their compromised immune system, which also promotes cancer progression through inflammation. Thus, this study aimed to develop novel chemotherapeutic agents with both anticancer and antimicrobial properties. A series of diarylurea derivatives based on pyridazinone scaffolds were designed, synthesized, and characterized as surrogates for sorafenib.

Novel N-substituted 5-aminosalicylamides as dual inhibitors of cyclooxygenase and 5-lipoxygenase enzymes: Synthesis, biological evaluation and docking study.

Three new series of 5-aminosalicylic acid derivatives; series I (14, 16-18), series II (19-30) and series III (31-41) were synthesized as potential dual COX-2/5-LOX inhibitors. Their chemical structures were confirmed using spectroscopic tools including IR, H NMR, C NMR, mass spectroscopy and elemental analyses. The anti-inflammatory activity for all target compounds was evaluated in vivo using carrageenan-induced paw edema.
