Three new heterocyclic ring systems, isoxazolo[4,5‐d]‐1,2,4‐triazolopyridazines 12‐15, tetrazolo‐[4,3‐b]pyridazine 18 and isoxazolo[4,5‐d]pyridazino[2,3‐c]2H‐triazines 16,17 along with isoxazolo[4,5‐d]pyridazines 2, 5‐10 have been synthesized. Preliminary screening of these tricyclic heterocycles revealed that some of them possess significant antibacterial and antifungal activity.
