ABSTRACT
A series of novel sulfonamide isoxazolo[5,4-b]pyridines were synthesized. The substrates for their synthesis were 3-aminoisoxazolo[5,4-b]pyridine and selected aryl sulfonic chlorides, chlorosulfonic acid and selected amines. Reactions were carried out using the classical and microwave methods. Selected compounds were tested towards antibacterial and antiproliferative activity. The structure of the obtained new derivatives was determined by elemental analysis and acquired IR and 1H NMR spectra. Among the tested compounds N- isoxazolo[5,4-b]pyridine-3-yl-benzenesulfonamide (2) and N-isoxazolo[5,4-b]pyridine-3-yl-4-methylbenzene-sulfonamide (5) showed antimicrobial activity towards Pseudomonas aeruginosa (ATCC 27853) and Escherichia coli (ATCC 25922) at doses 125, 250 and 500 µg. Both compounds showed a 50% inhibition of proliferation of breast carcinoma cell line MCF7 at concentrations of 152.56 µg/mL and 160 161.08 µg/mL, respectively.
