    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 .

    KL-2

    		 Others 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 .

    BAY-958

    		CDK Cancer
    BAY-958 is a potent PTEFb/CDK9 inhibitor with high selectivity demonstrated in vitro, particularly within the CDK family. It shows strong antiproliferative activity against cancer cell lines such as HeLa and MOLM-13. In pharmacokinetic studies, BAY-958 exhibited good metabolic stability but had low aqueous solubility and moderate permeability, leading to challenges in bioavailability. Despite these limitations, BAY-958 hydrochloride effectively inhibited tumor growth in mouse xenograft models without significant toxicity, indicating promising efficacy in vivo. However, its suboptimal physicochemical properties prompted further development efforts to identify compounds with improved overall characteristics for potential clinical use .
