SKI-73 (6a) can rapidly penetrate cell membranes and then be processed into active inhibitors, which are retained intracellularly with 10-collapse enrichment for a number of days. These compounds were characterized for his or her potency, selectivity, modes of action, and on-target engagement. SKI-73 (6a) recapitulates the effect of CARM1 knockout against breast malignancy cell invasion. Single-cell RNA-seq analysis revealed the SKI-73(6a)-associated reduction of invasiveness functions by altering epigenetic plasticity and suppressing the invasion-prone subpopulation. Interestingly, SKI-73 (6a) and CARM1 knockout alter the epigenetic plasticity with amazing difference, suggesting unique modes of action for small-molecule and genetic perturbations. We therefore found out a CARM1-habit mechanism of malignancy metastasis and developed a chemical probe to target this process.
