Sodium tanshinone IIA sulphonate (T06) is a water-soluble derivative of tanshinone IIA, that displays versatile biological properties. Recently, it has been shown to act as an ectosteric inhibitor of cathepsin K (CatK). T06 binds in an ectosteric side of Cathepsin K remote from its active site and selectively inhibits collagen degradation. It also inhibits bone resorption in ovariectomized mice.
