SCR7,1533426-72-0,IC-0212621
Scr7 is a DNA ligase IV inhibitor, initially identified as an anti-cancer agent [1]. Scr7 targets the DNA binding domain of DNA ligase IV, reducing its affinity for double strand breaks (DSBs) and inhibiting its function. Scr7 also inhibits DNA ligase III (but not DNA ligase I), albeit less efficiently. Cells were treated with doxycycline to induce Cas9 expression, with various concentrations of Scr7 for 24 h. Scr7 maintained cells capable of entering S/G2 phase, which is necessary for HDR. [1] Treatment of mice with Scr7 affects lymphocyte development, as DNA ligase IV plays a key role in the joining of coding ends during V(D)J recombination by means of C-NHEJ16. The defects in lymphocyte development upon Scr7 treatment are transient and reversible, due to the noncovalent mode of binding of Scr7. Scr7 enhanced the frequency of HDR by transiently blocking NHEJ (with the exception of DNA ligase I–dependent alt-NHEJ), resulting in precise genome editing by CRISPR-Cas9 in both cultured cells and in mice.
