Discovery of 2,4-dianilinopyrimidine derivatives as novel p90 ribosomal S6 protein kinase (RSK) inhibitors.

Summary: Cancer cells rely on a special protein called RSK to grow, multiply, and survive. Because of this, scientists are trying to find ways to block this protein to treat cancer. In this study, researchers created a new group of chemical compounds in the lab to see if they could stop the RSK protein from working. After testing them, they discovered that one specific compound, named "3e", did a fantastic job at blocking RSK. This exciting discovery means compound 3e could be a great starting point for developing a brand-new cancer drug!
