An efficient two-step synthesis of pyrazoline ligand 1 is described which is an effective âturn onâ fluorescent sensor for Cd2+ in MeCN. Oxidation to the corresponding pyrazole ligand 2 creates a âturn onâ fluorescent sensor now selective for Zn2+ and able to distinguish it from Cd2+.

The synthesis and antiproliferative activity of eleven 3-(pyrid-2-yl)-pyrazolines in two cancer cell lines are reported. X-ray crystallography was obtained of the lead compound 8i which was screened in the NCI 60 human tumour cell line and displayed sub-micromolar activity. Cell cycle analysis, in vitro tubulin assay and confocal microscopy are also reported and suggest that the lead compound disrupts microtubule formation.
