Abstract
Hydrazonoyl halides were used as precursors for the synthesis of a new series of bis-spiropyrazoles via reaction with 3,5-diarylidene-piperidone derivatives under ultrasound irradiation. The products were secluded in good yield after short reaction periods.
The anticancer activity of bis-spiropyrazoles against HepG2 (hepatic cancer), A549 (lung cancer) and CaCo2 (colon cancer) cell lines was screened. Three tested compounds 4b, 4c and 4f showed promising activity.
