Rbin-1(ribozinoindole-1) is a potent chemical inhibitor of eukaryotic ribosome assembly. It inhibits recombinant full-length Mdn1's ATPase activity in vitro.

YU238259 is a novel inhibitor of homology-dependent DNA repair(HDR), but does not inhibit non-homologous end-joining (NHEJ), in cell-based GFP reporter assays.

E7449 is an orally bioavailable, brain penetrable, small molecule dual inhibitor of PARP1/2 and also inhibits PARP5a/5b, otherwise known as tankyrase1 and 2 (TNKS1/2), important regulators of canonical Wnt/β-catenin signaling. It has IC50 values of 1.0 and 1.2 nM for PARP1 and 2, respectively.

LTURM34 is a specific DNA-PK inhibitor, 170-fold more selective for DNA-PK activity compared to PI3K activity, with IC50 value of 0.034 μM.

B02 is a small-molecule inhibitor of human RAD51 with an IC50 of 27.4 μM, but does not inhibit its E. coli homologue RecA (IC50 > 250 μM).

Salermide is a reverse amide with a strong in vitro inhibitory effect on Sirt1 and Sirt2. Compared with Sirt1, Salermide is even more efficient at inhibiting Sirt2.

SRT3025 HCL is an orally available small molecule activator of the SIRT1 enzyme.

TAS-102 is an orally administered combination of a thymidine-based nucleic acid analogue, trifluridine, and a thymidine phosphorylase inhibitor, tipiracil hydrochloride.
