We describe a convenient synthetic pathway to access the 12-membered PCTA macrocycle, a polyaminocarboxylate ligand for which its M2+ and M3+ complexes are commonly associated with applications in biomedical diagnostics and radiother

The interactions of gefitinib (Iressa) in EGFR are hydrogen bonding and van der Waals forces through quinazoline and aniline rings. However the morpholino group of gefitinib is poorly ordered due to its weak electron density. A series of novel piperazino analogues of gefitinib where morpholino group substituted with various piperazino groups were designed and synthesized. Most of them indicated significant anti-cancer activities against human cancer cell lines. In particular, compounds 52-54 showed excellent potency against cancer cells. Convergent synthetic approach has been developed for the synthesis of gefitinib intermediate which can lead to gefitinib as well as numerous analogues.

A new rhodamine appended tripodal receptor 1 has been designed and synthesized. The receptor selectively recognizes Hg2+ ions in CH 3CN-water (4:1, v/v; 10 μM tris HCl buffer, pH 7.0) by displaying a ratiometric change in emission. Additionally, the visual detection is possible by a sharp change in color. The receptor shows in vitro detection of Hg 2+ ions in human cervical cancer (HeLa) cells.
