LTURM34 is a specific DNA-PK inhibitor (IC₅₀=34 nM). LTURM34 exhibits 170-fold selectivity for DNA-PK over PI3K. LTURM34 shows potent antiproliferative activity in a wide range of tumor cell lines^[1].

LTURM34 shows potent inhibition of DNA-PK with excellent selectivity over the Class I PI3K isoforms. The IC₅₀s are 5.8 and 8.5 μM for PI3K β and δ, respectively. LTURM34 is more consistently active against the selected cell lines (11 of 16), but at best shows 54% inhibition against the HOP-92 non-small cell lung cancer line^[1].

LTURM34 is dissolved at 10 mM in DMSO and stored at -20°C until use. PI3K enzyme activity is determined in 50 μL of 20 mM HEPES pH 7.5, 5 mM MgCl₂ with 180 μM PI and 10 μM ATP. After a 60 min incubation at room temperature the reaction is stopped by the addition of 50 μl of Kinase-Glo followed by a further 15 min incubation. Luminescence is then read using a luostar plate reader. LTURM34 is diluted in 20% (v/v) DMSO at the ndicated concentrations in order to generate a concentration versus inhibition of enzyme activity curve which is then analysed using GraphPad Prism version 5.00 for Windows, in order to calculate the IC50^[1].
