Development of a High-Throughput Lysyl Hydroxylase (LH) Assay and Identification of Small-Molecule Inhibitors against LH2.

ABSTRACT: Lysyl hydroxylase-2 (LH2) catalyzes the hydroxylation of telopeptidyl lysine residues on collagen, leading to the formation of stable collagen cross-links that connect collagen molecules and stabilize the extracellular matrix. High levels of LH2 have been reported in the formation and stabilization of hydroxylysine aldehyde-derived collagen cross-links (HLCCs), leading to fibrosis and cancer metastasis in certain tissues. Identification of small-molecule inhibitors targeting LH2 activity requires a robust and suitable assay system, which is currently lacking. Thus, despite being a promising target for these diseases, small-molecule inhibitors for LH2 have yet to be reported. Therefore, we developed a luminescence-based strategy to monitor LH activity and validated its ability to identify n
