ONO-8809 is a thromboxane A2 receptor antagonist. ONO-8809 inhibited the LTC4-induced airway hyperresponsiveness to histamine in a dose-dependent manner. Macrophage accumulation and matrix metalloproteinase-9 (MMP-9) activity in the stroke-negative area i
SKF-80723 HBr is a D1 receptor agonist. SKF-80723 HBr strongly potentiated the contralateral circling induced by quinpirole in rats with a unilateral 6-hydroxydopamine (6-OHDA) lesion of the medial forebrain bundle.
The early stage of atherosclerosis is characterized by the aggregation of foam cells, so called a fatty streak, in the inner arterial wall. CAY10487 inhibits formation of fatty streak lesions of the thoracic aorta in high cholesterol-fed rabbits without affecting plasma lipid profiles or significantly inhibiting ACAT-1 or ACAT-2 activity. The percent area occupied by the atherosclerotic lesion in rabbits supplemented with 0.05% CAY10487 in the diet was 16.1% compared to 53.5% in control rabbits. CAY10487 also exhibits antioxidant activity, inhibiting copper-mediated oxidation of low-density lipoprotein by about 75% at a concentration of 2 μM.
Malformin A is a cyclopentapeptide fungal metabolite that has been found in A. niger and has diverse biological activities. It is a plant growth regulator that induces malformations in plant structure. Malformin A inhibits replication of tobacco mosaic virus (TMV) in local lesion and leaf-disc assays (IC50s = 19.7 and 45.4 μg/ml, respectively). It is cytotoxic to NCI-H460, MIA PaCa-2, MCF-7, SF-268, and WI-38 cancer cells (IC50s = 70, 50, 100, 70, and 100 nM, respectively), inhibits proliferation of PC3 and LNCaP cells (IC50s = 130 and 90 nM, respectively), and induces apoptosis and necrosis in PC3 and LNCaP cells. Malformin A also increases the accumulation of reactive oxygen species, decreases the mitochondrial membrane potential, and induces autophagy in PC3 and LNCaP cells. It is toxic to mice when administered intraperitoneally (LD50 = 3.1 mg/kg) but not orally up to doses of 50 mg/kg.
Selective sigma (σ) receptor ligand. Displays high affinity for σ1; also binds at σ2 sites (Ki = 1.5 nM and 50.8 nM respectively). Selective over a range of receptor types including dopaminergic and muscarinic receptors, DAT and SERT.

Melagatran monohydrate is a thrombin inhibitor. Melagatran prevents tissue factor expression in human platelet-monocyte heterotypic complexes. Melagatran reduces advanced atherosclerotic lesion size and may promote plaque stability in apolipoprotein E-deficient mice.
