Metarrestin (ML246) is an orally active, first-in-class and specific perinucleolar compartment inhibitor. Metarrestin disrupts the nucleolar structure and inhibits RNA polymerase (Pol) I transcription, at least in part by interacting with the translation elongation factor

MW150 (MW01-18-150SRM) is a selective, CNS penetrant, and orally active inhibitor of p38α MAPK with a Ki of 101 nM. MW-150 inhibits the ability of the endogenous p38α MAPK to phosphorylate an endogenous substrate MK2

PARPi-FL (Olaparib-bodipy FL) is a small-molecule fluorescent inhibitor of PARP1 that can specifically bind to PARP1. PARPi-FL can be used as a fluorescent imaging agent for tumor detection, diagnosis, and surgical guidance.
