ABSTRACT
Crellastatin A, a cytotoxic sulfated bis-steroid isolated from the Vanuatu Island marine sponge Crella sp., was selected as an interesting probe for a comprehensive proteomic analysis directed at the characterization of its protein interactors. Given its peculiar structural features, A was submitted to a mass spectrometry-based drug affinity responsive target stability (DARTS) assay combined with (targeted-limited proteolysis-multiple reaction monitoring (t-LiP MRM), rather than a classical affinity purification strategy. Poly-ADP-ribose-polymerase-1 (PARP-1) emerged as the main crellastatin A cellular partner. This result was confirmed by both biochemical and in silico analyses. Further inâ
vitro biological assays highlighted an interesting crellastatin A inhibitory activity on PARP-1.
