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).
