ri-1

RI-1 (RAD51 inhibitor 1) is a RAD51 inhibitor (IC50: 5-30 μM).

5’-O-DMT-Ri can be used in the synthesis of oligoribonucleotides[1]. [1]. Kadokura M.

Pegsunercept (PEG sTNF-RI), a pegylated monoclonal antibody, selectively binds to TNFA, incorporating a polyethylene glycol (pegol) moiety [1].

RI(dl)-2 TFA is a potent and selective RAD51-mediated D-loop formation inhibitor with an IC 50 of 11.1 μM which also inhibits homologous recombination(HR) activity in human cells with IC50 of 3.0 μM[1].

RI-962 is a potent and selective inhibitor of receptor-interacting protein kinase 1 (RIPK1), exhibiting an IC50 of 35.0 nM. It is utilized for the investigation of nervous system disorders and inflammatory diseases [1].
