Title Inhibition of glutaminase preferentially slows growth of glioma cells with mutant IDH1.

Abstract Text Mutation at the R132 residue of isocitrate dehydrogenase 1 (IDH1), frequently found in gliomas and acute myelogenous leukemia, creates a neoenzyme that produces 2-hydroxyglutarate (2-HG) from α-ketoglutarate (α-KG). We sought to therapeutically exploit this neoreaction in mutant IDH1 cells that require α-KG derived from glutamine. Glutamine is converted to glutamate by glutaminase and further metabolized to α-KG. Therefore, we inhibited glutaminase with siRNA or the small molecule inhibitor bis-2-(5-phenylacetamido-1,2,4-thiadiazol-2-yl)ethyl sulfide (BPTES) and found slowed growth of glioblastoma cells expressing mutant IDH1 compared with those expressing wild-type IDH1. Growth suppression of mutant IDH1 cells by BPTES was rescued by adding exogenous α-KG. BPTES inhibited glutaminase activity, lowered glutamate and α-KG levels, and increased glycolytic intermediates while leaving total 2-HG levels unaffected. The ability to selectively slow growth in cells with IDH1 mutations by inhibiting glutaminase suggests a unique reprogramming of intermediary metabolism and a potential therapeutic strategy.


  • Case insensitive filtering will display rows if any text in any cell matches the filter term
  • Use simple literal full or partial string matches
  • Separate multiple filter terms with a space. Any order may be used (i. e. a b c and c b a are equivalent )
  • Filtering will only apply to rows that are already loaded on the page. Filtering has no impact on query parameters.
  • Use quotes to match on a longer phrase with spaces (i.e. "mtor c1483f")


  • Generally, the default sort order for tables is set to be first column ascending; however, specific tables may set a different default sort order.
  • Click on any column header arrows to sort by that column
  • Hold down the Shift key and click multiple columns to sort by more than one column. Be sure to set ascending or descending order for a given column before moving on to the next column.

BPTES bis-2-(5-phenylacetamido-1,2,4-thiadiazol-2-yl)ethyl sulfide Glutaminase Inhibitor 3 BPTES is a small molecule that inhibits glutaminase, which results in decreased conversion of glutamine to glutamate, and potentially leads to decreased tumor cell growth (PMID: 21045145, PMID: 25915584, PMID: 32450839).
