The present invention relates to a method for preparing microvesicular ADAM15, comprising: (a) a step of activating protein kinase C (PKC) of separated mammalian cells; and (b) a step of separating microvesicle-containing ADAM15 from the mammalian cells. According to the present invention, a method for preparing microvesicular ADAM15 from mammalian cells is provided, and a novel cell regulation mechanism mediated by ADAM proteins is provided by the study of the function of the microvesicular ADAM15. Further, the present invention may provide a novel anti-cancer drug using microvesicular ADAM15, which inhibits adhesion, proliferation and migration of tumor cells.

The present application discloses the use of a family of abietane derivatives as activators of PKC family isoforms. The present application provides a small molecule selective activator of isoform delta of protein kinase C (PKCdelta), the 7alpha-acetoxy- 6beta-benzoyloxy-12-0-benzoylroyleanone (Roy-Bz), a semi-synthetic derivative of the natural diterpenoid 7alpha-acetoxy- 6beta-hydroxyroyleanone (Roy) isolated from a Lamiaceae family plant. Roy-Bz belongs to a novel family of small molecule modulators of PKC activity, the abietane derivatives with the general formula shown in Figure 1 wherein X, Y, Z, W; Rl, R2, R3, R4 and R5 are as defined herein, as a stereoisomer, enantiomer, racemate, tautomer thereof or mixtures thereof; or a pharmaceutically acceptable salt, solvate or prodrug thereof and their use as activators of PKC family isoforms.
