D-I03 is a selective RAD52 inhibitor with a Kd of 25.8 µM. It specifically inhibits RAD52-dependent single-chain annealing (SSA) and D-loop formation, with IC50 values of 5 µM and 8 µM, respectively. D-I03 also inhibits the growth of BRCA1 and BRCA2 deficient cells and prevents the formation of damage-induced RAD52 foci, but does not affect RAD51 foci induced by Cisplatin.

Polyinosinic-polycytidylic acid sodium (Poly(I:C) sodium) is a synthetic analog of double-stranded RNA and an agonist of toll-like receptor 3 (TLR3) and retinoic acid inducible gene I (RIG-I)-like receptors (RIG-I and MDA5).
