The present invention relates to 4-piperidone derivatives represented by the following formula (I) and the acid addition salts thereof. The synthesis of new compounds is disclosed herein, together with experiments demonstrating their activity in cytotoxicity (IC50) assays against cancer cell lines and their preferential toxicity toward cancerous cells (vs. non-malignant cells). The compounds are also useful in reversing MDR (multidrug resistance).

Metal Complexes with Nitronyl Nitroxide Substituted Phenolate Ligands Providing New Magnetic Exchange Interaction Pathways − Synthesis, Structures, Magnetic Dilution Studies, and Ab Initio Calculations
The synthesis and magneticproperties of seven new nitronylnitroxide substituted phenolates with chelating amine groups are reported. Copper(II) and nickel(II) complexes prepared with these ligands are structurally and magnetically characterized, showing exchange interactions between the metal and the radical ligands through the phenolate oxygen. Magnetically diluted samples are prepared by embedding

Cytotoxic benzylidene hydrazides of terephthalic acid and related compounds
The present investigation involved the synthesis of a number of novel benzylidene hydrazides as candidate cytotoxic agents. The preparation of these compounds from terephthalic acid and isophthalic acid proceeded satisfactorily. However, the reaction of phthalic acid hydrazide with various aryl aldehydes was unsuccessful in general. Some of the unexpected products were identified. The shapes and also
