available reagents. After evaluating 63 analogues against human coronavirus 229E, four of the best molecules were selected and shown to have micromolar activity against SARS-CoV-2. Since the action point was situated post virus entry and lying at the stage of viral polyprotein processing and the start of RNA synthesis, enzymatic assays were performed with CoV proteins involved in these processes. While no inhibition

at the C-4 position of the piperidine ring are important for optimal cytostatic properties. Compounds 20, 22, 27 and 29 were found to be the most potent with a 50% inhibitory concentration (IC50) ranging between 3 and 9.5 μM in the cancer cell lines evaluated. The NCI60 screen confirmed this 50% cytostatic concentration range for compound 20, irrespective of the nature of the tumor cell lines evaluated
