A-20832 inhibits resolvase-promoted site-specific recombination postsynaptically at strand cleavage. It does not inhibit resolvase binding to res, as measured by filter binding, or synapse formation. DNase I analysis in the presence of A-20832 indicates t
BMS 186318 is a human immunodeficiency virus (HIV) protease inhibitor designed to examine the possibility of developing resistance when two protease inhibitors are used together in recombination.
CAY10760 is an inhibitor of the protein-protein interaction between RAD51 recombinase and BRCA2 (EC50= 19 μM in a cell-free competitive ELISA).1It decreases homologous recombination by 54% in wild-typeBRCA2-expressing BxPC-3 pancreatic cancer cells when used at a concentration of 20 μM. CAY10760 (20 μM) decreases proliferation of BxPC-3, as well as mutantBRCA2-expressing Capan-1, cancer cells when used alone or in combination with the poly(ADP-ribose) polymerase (PARP) inhibitor olaparib . 1.Bagnolini, G., Milano, D., Manerba, M., et al.Synthetic lethality in pancreatic cancer: Discovery of a new RAD51-BRCA2 small molecule disruptor that inhibits homologous recombination and synergizes with olaparibJ.

NT1-O12B, an endogenous neurotransmitter-derived lipidoid (NT-lipidoid), serves as a highly efficient carrier for enhancing the transportation of various blood-brain barrier (BBB)-impermeable cargos to the brain. Incorporating NT1-O12B into BBB-impermeable lipid nanoparticles (LNPs) enables these LNPs to effectively traverse the BBB. In addition to enabling cargo passage through the BBB, NT-lipidoid formulations facilitate efficient delivery of the cargo into neuronal cells for purposes such as functional gene silencing or gene recombination[1].
MI-223 is an inhibitor of Mcl-1-stimulated homologous recombination (HR) DNA repair, which leads to sensitization of cancer cells to hydroxyurea- or olaparib-induced DNA replication stress.
53BP1-binding protein 1 (53BP1) engages with dimethylated lysine 20 on histone 4 (H4K20me2) through its tandem tudor domains within a homodimer configuration, crucial for the DNA damage response. UNC2170, a micromolar 53BP1 ligand, selectively interacts with this site, demonstrating at least 17-fold preference for 53BP1 over similar proteins. This interaction occurs in a pocket formed by the 53BP1's tudor domains. Moreover, UNC2170 acts as an antagonist to 53BP1 in cellular lysates, effectively inhibiting class switch recombination, a process dependent on the functional 53BP1 tudor domain, thus confirming its cellular activity.
