    PR-957

    		 Proteasome Bacterial HIV Infection Inflammation/Immunology
    ONX-0914 (PR-957) is a selective inhibitor of low-molecular mass polypeptide-7 (LMP7), the chymotrypsin-like subunit of the immunoproteasome. ONX-0914 blocks cytokine production and attenuates progression of experimental arthritis. ONX-0914 is a noncompetitive irreversible inhibitor of the mycobacterial proteasome (Ki=5.2 μM). ONX-0914 reactivates latent HIV-1 through p-TEFb activation mediated by HSF-1 .

    KI-DX-014

    		ATP Synthase DNA/RNA Synthesis Neurological Disease Cancer
    KI-DX-014 is a DDX21 inhibitor with high RNA-binding inhibitory activity (IC50 of 3.31 μM). KI-DX-014 targets DDX21’s intrinsically disordered C-terminal domain, inhibits DDX21-structured RNA interaction, modulates DDX21’s RNA-dependent ATPase activity, and disrupts DDX21 biomolecular condensate formation. KI-DX-014 attenuates in vitro P-TEFb release from the 7SK snRNP complex, suppresses P-TEFb-dependent RNA polymerase II CTD phosphorylation, and induces developmental defects in zebrafish embryos. KI-DX-014 acts as a chemical probe for dissecting DDX21 functions in normal physiology and disease states. KI-DX-014 can be used for cancers and neurodegenerative disorders research .

    KL-2

    		 DNA/RNA Synthesis Cancer
    SEC inhibitor KL-2 (KL-2), a peptidomimetic lead compound, is a potent, selective super elongation complex (SEC) inhibitor and disrupts the interaction between the SEC scaffolding protein AFF4 and P-TEFb, resulting in impaired release of Pol II from promoter-proximal pause sites and a reduced average rate of processive transcription elongation. SEC inhibitor KL-2 exhibits an dose-dependent inhibitory effect on AFF4-CCNT1 interaction with a Ki of 1.50 μM .
