Abstract: A series of 14-diarylidene-1-phenethylpiperidine-4-one derivatives were synthesized using Claisen-Schmidt
condensation reactions. The synthesized compounds were screened for their antimycobacterial activity against Mycobacterium
tuberculosis (MTB) H37Rv using High Throughput Screen (HTS) using an assay adapted from the microdilution
alamarBlue (AB) broth assay reported by Collins and Franzblau and additionally an alternative method for end-point detection
was assessed using the Promega reagent BacTiter-Glo™ Microbial Cell Viability (BTG). Most of the compounds
showed low-to-moderate activity with MIC of less than 30μM. Compound (3d) (3E,5E)-3,5-bis (4-triflouromethylbenzyledene)-
1-phenethylpiperidin-4-one was found to be the most active with MIC of 27.00 μM.
