Application
RAD51 Inhibitor B02 has been used:
- to test its effect on the polar body extrusion (PBE) rate in porcine oocytes
- for RAD51 inhibition in porcine embryos
- as RAD51 inhibitor and to test its effect on targeted nucleotide substitution (TNS) in induced pluripotent stem cells (iPSCs)
Biochem/physiol Actions
B02 (3-(Phenylmethyl)-2-[(1E)-2-(3-pyridinyl)ethenyl]-4(3H)-quinazolinone), a pyridinylvinyl-quinazolinone compound is cell-permeable. B02 inhibits human RAD51 recombinase and subsequent nucleofilaments formation. It halts homologous recombination (HR) repair events in cancer cells. B02 favors apoptosis in multiple myeloma and is crucial for sensitizing them to doxorubicin.

In checkpoint-deficient cells, DNA double-strand breaks (DSBs) are produced during replication by the structure-specific endonuclease MUS81. The mechanism underlying MUS81-dependent cleavage, and the effect on chromosome integrity and viability of checkpoint deficient cells is only partly understood, especially in human

Homologous recombination (HR) plays a critical role in facilitating replication fork progression when the polymerase complex encounters a blocking DNA lesion, and it also serves as the primary mechanism for error-free DNA repair of double-stranded breaks. DNA repair protein RAD51
