Radiolabeled Selective Matrix Metalloproteinase 13 (MMP-13) Inhibitors: (Radio)Syntheses and in Vitro and First in Vivo Evaluation

The noninvasive imaging of MMP activity in vivo could have a high impact in basic research as well as in clinical applications. This approach can be established using radiolabeled MMP inhibitors (MMPIs) as tracers for the detection of activated MMPs by means of PET. However, the complexity of diseases associated with dysregulated MMP expression necessitates the imaging of distinct MMPs or MMP subgroups to distinguish their individual role in specific diseases. To this end, selective and potent MMP-13 inhibitors based on a N,N′-bis(benzyl)pyrimidine-4,6-dicarboxamide core have been synthesized and successfully radiolabeled with carbon-11, fluorine-18, and gallium-68. Selected radiolabeled candidates were evaluated in vitro and in vivo regarding their pharmacokinetic properties and metabolic stability.

HISTONE LYSINE DEMETHYLASE INHIBITORS

The invention provides a compound which is an iV-oxalylglycine derivative of formula (I): a hydroxamic acid derivative of formula (II): or a heteroaryl derivative of fomula (III): wherein n; Z1; Z2; Y1; Y2; A; p; X1; X2; m; R4; B; R5; R6; R7; R8; R9; X3; R10; R11 and R12 are as defined herein, or a pharmaceutically acceptable salt thereof. These compounds are inhibitors of the human 2-oxoglutarate-dependant JMJD2 subfamily of histone demethylases, in particular JMJD2E. Such inhibitors are useful in changing the epigenetic state of cells resulting in the inhibition / activation of chromatin remodelling, multiple gene activation / deactivation, and in treating cancer and other conditions characterised by undesirable cellular proliferation, and psychiatric disorders including depression.
