MK-8245 is a liver-targeting inhibitor of stearoyl-CoA desaturase (SCD) with IC50 of 1 nM for human SCD1 and 3 nM for both rat SCD1 and mouse SCD1, with anti-diabetic and anti-dyslipidemic efficacy.IC50 value: 1 nM (hSCD1) [1]Target: SCD1in vitro: MK-8245, a phenoxy piperidine isoxazole derivative, has been identified as a potent and liver-specific SCD inhibitor. It contains a tetrazole acetic acid moiety, which is the key molecule for OATPs recognition and liver-targeting. MK-8245 displays similar potencies against human, rat and mouse SCD1 with IC50 values of 1 nM for human SCD1 and 3 nM for both rat SCD1 and mouse SCD1. MK-8245 exhibits a significant SCD inhibition in the rat hepatocyte assay which contains functional, active OATPs with IC50 of 68 nM, while being only weakly active in the HepG2 cell assay which is devoid of active OATPs with IC50 of ~1 μM. MK-8245 displays highly selective activity for the Δ-5 and Δ-6 desaturases (i.e., >100000 μM vs rat and human Δ5D and Δ6D as assessed in the HepG assay [1].in vivo: Administration of MK-8245 at 10 mg/kg in mice exhibits a tissue distribution profile concentrated in the liver. It shows a liver-to-Harderian gland ratio of 21, suggesting a high degree of liver-targeting compared to a systemically distributed compound with liver-to-Harderian gland ratio of 1.5. Oral dosing of MK-8245 in mice, rats, dogs, and rhesus monkeys demonstrates that MK-8245 is distributed mainly to the liver, with low exposure in tissues associated with potential adverse events. The liver-to-skin ratios are >30:1 in all four species. Administration of MK-8245 to eDIO mice before the glucose challenge improves glucose clearance in a dose-dependent manner with ED50 of 7 mg/kg.

Pitavastatin (NK-104) is a potent HMG-CoA reductase inhibitor, Pitavastatin inhibited cholesterol synthesis from acetic acid with an IC50 of 5.8 nM in a human liver cancer cell line (HepG2).IC50 value: 5.8 nM(cholesterol synthesis from aceticacid in HepG2) [1]Target: HMG-CoA reductasein vitro: Pitavastatin inhibited cholesterol synthesis from aceticacid with an IC50 of 5.8 nM in a human liver cancer cell line (HepG2), which indicates that is 2.9 and 5.7 times as potent as simvastatin and atorvastatin, respectively. 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].

Hydralazine Hydrochloride is a direct-acting vasodilator that is used as an antihypertensive agent.Target: OthersHydralazine (apresoline) is a direct-acting smooth muscle relaxant used to treat hypertension by acting as a vasodilator primarily in arteries and arterioles. By relaxing vascular smooth muscle, vasodilators act to decrease peripheral resistance, thereby lowering blood pressure and decreasing afterload. However, this only has a short term effect on blood pressure, as the system will reset to the previous, high blood pressure necessary to maintain pressure in the kidney necessary for natriuresis. The long term effect of antihypertensive drugs comes from their effects on the pressure natriuresis curve. It belongs to the hydrazinophthalazine class of drugs [1]. Hydralazine may reduce blood pressure when compared to placebo in patients with primary hypertension, however this data is based on before and after studies, not RCTs. Furthermore, its effect on clinical outcomes remains uncertain [2].

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].
