Keeping in mind the immense biological potential of chalcones and sulfonamide scaffolds, a library of sulfonamide chalcones has been synthesized and evaluated for in vitro antifilarial assay against human lymphatic filarial parasite Brugia malayi. Experimental evidence showcased for the first time the potential of some sulfonamide chalcones as effective and safe antifilarial lead molecules against human lymphatic filarial parasite B. malayi. Sulfonamide chalcones 4d, 4p, 4q, 4t and 4aa displayed the significantly wide therapeutic window. Particularly chalcones with halogen substitution in aromatic ring proved to be potent antifilarial agents against Brugia malayi. Sulphonamide chalcones with lipophilic methyl moiety (4q and 4aa) at para position of terminal phenyl rings of compounds were found to have remarkable antifilarial activities with therapeutic efficacy. Observed preliminary evidence of apoptosis by effective chalcone derivatives envisaged its fair possibility to inhibit folate pathway with consequent defect in DNA synthesis.

Introduction: Toxoplasmosis, a zoonotic infection caused by the apicomplexan parasite , affects a significant portion of the global human population. This condition, particularly dangerous for pregnant women and immunocompromised individuals, currently lacks effective treatment options.
Methods: Eighteen coumarin-based derivatives were synthesized, comprising coumarin-chalcone hybrids (5a-i) and coumarin-pyrazoline hybrids (6a-i).

Cancer is the second leading cause of death worldwide and is considered a major public health problem. Despite the significant advances in cancer research, the conventional cancer treatment approaches often lead to serious side effects that affect the quality of life of cancer patients. Thus, searching for new alternatives for cancer treatment is crucial to minimize these problems.

Multidrug resistance (MDR) mechanisms in cancer cells are greatly influenced by glutathione transferase P1-1 (hGSTP1-1). The use of synthetic or natural compounds as hGSTP1-1 inhibitors is considered an effective approach to overcome MDR. Nine compounds consisting of coumarin-6-sulfonamide linked to chalcone derivatives were synthesized and evaluated for their ability to inhibit hGSTP1-1.
