Abstract: A number of N-4-(2-aminoethoxy)phenylcarbonyl derivatives of various 3,5-bis(benzylidene)-4-piperidones 2-5 demonstrated noteworthy cytotoxic potencies towards human HL-60 leukemic cells as well as human HSC-2 and HSC-4 squamous cell carcinomas. In general, toxicity towards HGF, HPC, and HPLF normal cells was substantially lower. The highest selective toxicity was noted when the terminal base is morpholine. Lead optimization was based on finding compounds which had (i) high cytotoxic potencies, (ii) a greater toxicity to neoplasms than normal cells, and (iii) drug-likeness based on the rule of five. From the biodata generated, 5a evolved as a promising lead compound for further development. The mode of action of 5a included the induction of apoptosis in HL-60 cells in which internucleosomal DNA fragmentation and activation of caspase-3 was noted. In addition, 5a caused autophagy in HSC-2 cells.
