Acid ceramidase (AC) is a cysteine hydrolase that plays a crucial role in the metabolism of lysosomal ceramides, important members of the sphingolipid family, a diversified class of bioactive molecules that mediate many biological processes ranging from cell structural integrity, signaling, and cell proliferation to cell death. In the effort to expand the structural diversity of the existing collection of AC inhibitors, a novel class of substituted oxazol-2-one-3-carboxamides were designed and synthesized. Herein, we present the chemical optimization of our initial hits, 2-oxo-4-phenyl-N-(4-phenylbutyl)oxazole-3-carboxamide 8a and 2-oxo-5-phenyl-N-(4-phenylbutyl)oxazole-3-carboxamide 12a, which resulted in the identification of 5-[4-fluoro-2-(1-methyl-4-piperidyl)phenyl]-2-oxo-N-pentyl-oxazole-3-carboxamide 32b as a potent AC inhibitor with optimal physicochemical and metabolic properties, showing target engagement in human neuroblastoma SH-SY5Y cells and a desirable pharmacokinetic profile in mice, following intravenous and oral administration. 32b enriches the arsenal of promising lead compounds that may therefore act as useful pharmacological tools for investigating the potential therapeutic effects of AC inhibition in relevant sphingolipid-mediated disorders.

A series of new benzimidazole bearing thiazolidinedione derivatives has been designed, synthesized by using conventional as well as microwave-assisted methods. Microwave-assisted synthesis caused a significant reduction in the reaction times and improvement in the yields of all the derivatives. All the new synthesized compounds were evaluated for their in vitro cytotoxic potential against selected human cancer cell lines of breast (MDAMB-231), prostate (PC-3), cervical (HeLa), lung (A549) and bone (HT1080) along with a normal kidney cells (HeK-293T). The compounds 17n, 17p and 17q were found to be potent cytotoxic with IC50 values in the range of 0.096–0.63 μM on PC-3, HeLa, A549 and HT1080 cancer cells. Most of the compounds have found to be safe on normal HeK-293T kidney cells in comparison to cancer cells. The treatment of cells with 17p and 17q showed the typical apoptotic morphological features like fragmentation and shrinkage of nuclei. Further, test compounds resulted in inhibition of cell migration through disruption of F-actin protein assembly. Hoechst, DCFH-DA staining, mitochondrial membrane and annexin binding assays revealed that the cancer cell proliferation was inhibited through induction of apoptosis in A549 cells.
