rad51 in 3

RAD51-IN-3, a Rad51 inhibitor, is chemically identified as (8aR,9R)-11'-chloro-6',8'-dihydroxy-2H,2'H-[3,8'-bi-1H-benzo[f]indene]-1,3,5',7'(4H,6H)-tetraone.

PARP1/BRD4-IN-3 (compound HF4) is an effective inhibitor of BRD4 and PARP1, with IC50 values of 1210 nM and 2019 nM respectively. The compound exhibits antiproliferative activity, induces apoptosis (apoptosis) and cell cycle arrest at the G0/G1 phase. Additionally, PARP1/BRD4-IN-3 causes DNA damage and reduces the expression of the Rad51 protein, demonstrating anti-tumor activity.

Halenaquinone is a phosphatidylinositol 3-kinase inhibitor. Halenaquinone specifically inhibits the secondary DNA binding of RAD51. Halenaquinone inhibits RANKL-induced osteoclastogenesis. Halenaquinone induces apoptosis in PC12 cells.

Phosphoramide mustard cyclohexanamine is the active metabolite of cyclophosphamide, an alkylating agent that cross-links DNA strands, organizes cell division and causes cell death, and has antitumor activity.

CAY10760 is a novel RAD51-BRCA2 protein–protein interaction inhibitor (EC₅₀ = 19 μM) that interferes with the homologous recombination process.
