Overview

7-hydroxystaurosporine is a synthetic derivative of staurosporine with potent antineoplastic (anticancer) activity. It acts as a broad-spectrum protein kinase inhibitor, targeting multiple kinases including serine/threonine kinase AKT, calcium-dependent protein kinase C (PKC), cyclin-dependent kinases (CDKs), checkpoint kinase Chk1, and others. By inhibiting these kinases, it disrupts cell cycle progression—arresting tumor cells at the G1/S phase—and impairs DNA repair mechanisms by inhibiting the G2 checkpoint via Chk1 inhibition, ultimately leading to apoptosis. The drug has been investigated in clinical trials for various advanced solid tumors and hematologic malignancies[1][2][5][10].
