Molecular Glues

Pomalidomide is a derivative of thalidomide and acts as an immunomodulator.

SR-5037 is an orally active inhibitor of CDK12 and CDK13, with an IC50 of 31 nM, and functions as a molecular glue degrader for CycK, demonstrating a DC50 of 30 nM and Dmax exceeding 98%. By inhibiting the enzymatic activity of the CDK12/CycK and CDK13/CycK complexes, SR-5037 facilitates the recruitment of DDB1, leading to proteasome-mediated degradation of CycK. This compound has shown efficacy in degrading active CycK in mouse models of triple-negative breast cancer and is a valuable tool for investigating treatment options in such malignancies.

PVTX-405 is a selective, orally bioavailable inhibitor targeting IKZF2, designed as a molecular glue degrader. With a DC50 of 0.7 nM and a Dmax of 91%, it enhances degradation efficiency while minimizing off-target effects, exhibiting an IC50 of 48 µM for hERG inhibition. PVTX-405 demonstrates significant antitumor activity by inhibiting the growth of MC38 tumors and shows improved efficacy when combined with immune checkpoint therapies, such as anti-PD1 or anti-LAG3, in mouse models.

PPACK dihydrochloride is a potent and selective irreversible inhibitor of thrombin. It serves as an alternative anticoagulant to lithium heparin for blood gas and electrolyte analyses in whole blood. Additionally, PPACK dihydrochloride inhibits plasminogen activator (rt-PA), preventing its binding to plasma protease inhibitors. This compound also reduces plasmin-induced endothelial permeability and morphological changes in bovine aortic endothelial cell monolayers, making it suitable for investigations in thrombosis-related research.
