Curdione, one of the major sesquiterpene compounds from Rhizoma Curcumae, has been shown to exhibit multiple bioactive properties.IC50 value: 60–80 μMTarget:In vitro: The study of the influence of curdione on the hemorheological changes in blood stasis model rats and thrombolysis in vitro showed that curdione only possessed thrombolytic effect in dose of 0.235 g·L-1 and 2.35 g·L-1, but has not the notable activity of thrombolysis [1]. The effects of curdione on human platelet aggregation induced by thrombin (0.3 U/ml) were tested in vitro. Curdione preferentially inhibited PAF- and thrombin- induced platelet aggregation in a concentration-dependent manner (IC50: 60–80 μM), whereas much higher concentrations of curdione were required to inhibit platelet aggregation induced by ADP and AA. Curdione also inhibited P-selectin expression in PAF-activated platelets. Moreover, curdione caused an increase in cAMP levels and attenuated intracellular Ca2+ mobilization in PAF-activated platelets. In vivo: Curdione showed significant antithrombotic activity [2].

RI-1 is a RAD51 inhibitor with IC50 ranging from 5 to 30 μM.IC50 Value: 5-30 μMTarget: RAD51in vitro: RI-1 sensitizes cells to DNA damage by directly and specifically disrupting HsRAD51 and inhibiting the ability of RAD51 to form filaments on ssDNA. In addition, RI-1 alone generates single-agent toxicity in all three cancer cell lines (HeLa, MCF-7 and U2OS) with LD50 values in the 20–40 μM range. RI-1 decreases the rejoining of γ-H2AX foci in G2 phase cells and results in a higher level of unrepaired DSBs 6 hours after irradiation. in vivo:
Epinastine(WAL801) is an antihistamine and mast cell stabilizer that is used in eye drops to treat allergic conjunctivitis.Target: Histamine ReceptorEpinastine shows a high affinity to H1-receptors in receptor binding studies in the guinea pig ileum.
