Data Source: Sanford-Burnham Center for Chemical Genomics (SBCCG) Source Affiliation: Sanford-Burnham Medical Research Institute (SBMRI, San Diego, CA) Network: NIH Molecular Libraries Production Centers Network (MLPCN) Grant Number: X01 MH083230-01 Assay Provider: Dr. Dmitri Rozanov, Sanford-Burnham Medical Research Institute, San Diego CA This assay was developed and performed to confirm hits originally identified in "uHTS for the identification of compounds that potentiate TRAIL-induced apoptosis of cancer cells" (AID 1443) and to study the structure-activity relationship on analogs of the confirmed hits. Compounds are either acquired from commercial sources or synthesized internally. The TRAIL-resistant cell line, MDA-MB-435 is used, because we would like to determine if compounds can potentiate TRAIL-mediated cytotoxicity not only in TRAIL-sensitive PPC-1 carcinoma cells(AIDs 1443 and 1624) but also in TRAIL-resistant cells.

- Biological Assay 5000 PPC-1 cells were plated and grown overnight. Compounds were plated and 4 hrs later, TRAIL was added to half of the plate while RPMI was added to the other half of the plate as a control. Plates were return to the incubator for 24 hrs. Plates were removed from the incubator and placed on the bench for 30 min and then 25 uL of Cell Titer Glo were added per well. Plates were placed on a rocker and then read on a luminometer. 5000 MDA-MB-231 cells were plated per well. Compound was added and 4 hrs later, TRAIL was added at 5 ng/mL; RPMI was added for a minus TRAIL control. Plates were incubated an additional 24 hrs, removed to the bench for 30 min, and then 25 uL of cell titer glo was added per well. Plates were placed on a rocker and read on a luminometer. Data were fit using PRISM.

Compounds are either acquired from commercial sources or synthesized internally. Cytotoxic chemotherapy induces apoptosis via a pathway involving mitochondria, sometimes referred to as the "intrinsic pathway." An acquired resistance to anticancer drugs commonly results from the accumulation of defects in components of the mitochondrial pathway for apoptosis. Discov
