LTURM34

LTURM34 is an inhibitor of DNA-PK with IC50 of 34 nM. LTURM34 displays effective antiproliferative activity in a wide range of tumor cell lines. LTURM34 shows 170-fold selectivity for DNA-PK over PI3K .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. LTURM34 displays effective inhibition of DNA-PK with excellent selectivity over the Class I PI3K isoforms (IC50s: 5.8 and 8.5 μM for PI3K β and δ, respectively) .
