When the inhibitory activity interms of the ED50 was compared with that of simvastatin,pitavastatin showed a 3-fold stronger activity in the rat and 15-fold stronger activity in a guinea pig model.22 The inhibitory effect of pitavastatin on sterol synthesis is thought to be liver-selective [1]. pitavastatin reduces total and phosphorylated tau levels in a cellular model of tauopathy, and in primary neuronal cultures. The decrease caused by pitavastatin is reversed by the addition of mevalonate, or geranylgeranyl pyrophosphate. The maturation of small G proteins, including RhoA was disrupted by pitavastatin, as was the activity of glycogen synthase kinase 3β (GSK3β), a major tau kinase [4].in vivo: Intravenous treatment with pitavastatin-incorporated nanoparticles, but not with control nanoparticles or pitavastatin alone, inhibited plaque destabilization and rupture associated with decreased monocyte infiltration and gelatinase activity in the plaque[2].The EAM model was established in BALB/c mice by immunization with murine α-myosin heavy chain. Mice were fed pitavastatin (5 mg/kg) or vehicle once daily for 3 weeks from day 0 to day 21 after immunization [3].

Cilostazol(OPC 13013; OPC 21) is a potent inhibitor of PDE3A, the isoform of PDE 3 in the cardiovascular system (IC50=0.2 uM).IC50 Value: 0.2 uM [1]Target: PDE3Ain vitro: Cilostazol caused a concentration-dependent increase in the cAMP level in rabbit and human platelets with similar potency. Furthermore, cilostazol and milrinone were equally effective in inhibiting human platelet aggregation with a median inhibitory concentration (IC50) of 0.9 and 2 microM, respectively. In rabbit ventricular myocytes, however, cilostazol elevated cAMP levels to a significantly lesser extent (p < 0.05 vs. milrinone) [2]. Cilostazol inhibited SIPA dose-dependently in vitro. The IC50 value of cilostazol for inhibition of SIPA was 15 +/- 2.6 microM (m +/- SE, n=5), which was very similar to that (12.5 +/- 2.1 microM) for inhibition of ADP-induced platelet aggregation. Cilostazolpotentiates the inhibition of SIPA by PGE1 and enhances its ability to increase cAMP concentrations [3].in vivo: A single oral adminstration of 100 mgcilostazol to healthy volunteers produced a significant inhibition of SIPA [3]. Male C57BL/6J mice were assigned to five groups: mice fed a normal diet (groups 1 and 2); 0.1% or 0.3% cilostazol-containing diet (groups 3 and 4, respectively); and 0.125% clopidogrel-containing diet (group 5). Two weeks after feeding, groups 2-5 were intraperitoneally administered carbon tetrachloride (CCl4 ) twice a week for 6 weeks, while group 1 was treated with the vehicle alone [4].Toxicity: Cilostazol in addition to dual antiplatelet therapy appears to be effective in reducing the risk of restenosis and repeat revascularization after PCI without any significant benefits for mortality or stent thrombosis [5].
