1 We chemically synthesized a non-hydrolyzable analog of the palmitoyl-cysteine thioester linkage (AcG-alpha-ketoamido-palmitoyl diamino propionate-VKIKK) (DAPKA) and showed that it inhibits palmitoyl:protein thioesterase (PPT1) in an in vitro assay using a specific fluorescent-based (4-methylumbelliferyl-beta-gluco-6-thiopalmitate) assay. palmitoyl-cysteine thioester palmitoyl-protein thioesterase 1 Homo sapiens
2 Overexpression of PPT1 protected against apoptosis induced by etoposide and the ketoamide and the inhibitory effect of the two was additive. Etoposide palmitoyl-protein thioesterase 1 Homo sapiens
3 Overexpression of PPT1 protected against apoptosis induced by etoposide and the ketoamide and the inhibitory effect of the two was additive. oxoazanide palmitoyl-protein thioesterase 1 Homo sapiens
