A Phosphoramidate Prodrug Platform: One-Pot Amine Functionalization of Kinase Inhibitors with Oligoethylene Glycol for Improved Water-Solubility.

Small molecular kinase inhibitors play a key role in modern cancer therapy. Protein kinases are essential mediators in the growth and progression of cancerous tumors, rendering involved kinases an increasingly important target for therapy. However, kinase inhibitors are almost insoluble in water because of their hydrophobic aromatic nature, often lowering their availability and pharmacological efficacy.
