Embodiments concern methods and small molecule compositions for selectively inhibiting RAD51-mediated D-loop formation while preserving RAD51's ability to form nucleoprotein filaments. The selective RAD51 D-loop formation activity inhibitors DNA repair while minimizing replication-associated toxicity in normal tissue.

target in oncology. Herein we report a novelclass of RAD51 inhibitors that were identified by high throughput screening. In contrast to many previously reported RAD51 inhibitors, our lead compound 1 is capable of blocking RAD51-mediated D-loop formation (IC50 21.3 ± 7.8 μM) at concentrations that do not influence RAD51 binding to ssDNA. In human cells, 1inhibits HR (IC50 13.1 ± 1.6 μM) without blocking
