Abstract
Phenotypic assays have a proven track record for generating leads that become first-in-class therapies. Whole cell assays that inform on a phenotype or mechanism also possess great potential in drug repositioning studies by illuminating new activities for the existing pharmacopeia. The National Center for Advancing Translational Sciences (NCATS) pharmaceutical collection (NPC) is the largest reported collection of approved small molecule therapeutics that is available for screening in a high-throughput setting. Via a wide-ranging collaborative effort, this library was analyzed in the Open Innovation Drug Discovery (OIDD) phenotypic assay modules publicly offered by Lilly. The results of these tests are publically available online at www.ncats.nih.gov/expertise/preclinical/pd2 and via the PubChem Database (https://pubchem.ncbi.nlm.nih.gov/) (AID 1117321). Phenotypic outcomes for numerous drugs were confirmed, including sulfonylureas as insulin secretagogues and the anti-angiogenesis actions of multikinase inhibitors sorafenib, axitinib and pazopanib. Several novel outcomes were also noted including the Wnt potentiating activities of rotenone and the antifolate class of drugs, and the anti-angiogenic activity of cetaben.

Abstract
Atherosclerosis is a major death cause in western industrialized countries. A diagnosing system, medical prevention, and treatment of atherosclerosis is not sufficient so far. A direct acting antiatherosclerotic agent is eagerly waited. ACAT inhibitor approach could provide such an agent. In the formation of atherosclerosis, cholesteryl esters, which are the lipids which accumulate in atheromatous plaques by an aid of macrophages and smooth muscle cells, forming foam cells, may play an important role. ACAT enzyme is responsible for the acylation of cholesterol to cholesteryl esters, a transformation which can be essential in not only cholesteryl esters accumulation at arterial walls but also the absorption of cholesterol in the intestine and the excretion of cholesterol in the liver. From these points, ACAT inhibitors might work against atherosclerosis in three different ways: first, cholesteryl ester accumulation inhibition at arterial walls could be a direct antiatherosclerotic effect; second, cholesterol absorption inhibition at the intestine; and third, cholesterol excretion acceleration at the liver, while the later two effects would result in a reduction of blood cholesterol level--a major risk factor of atherosclerosis. Taking account of this discussion, the ACAT inhibitors would be potent antiatherosclerotic agents. Medicinal research has been contributing full strength to produce an ultimate compound. These efforts should provide a drug which will be useful to patients.

Abstract
1. Cetaben in contrast to fibrates affect differently peroxisomal constituents. 2. Changes in large scale of liver non-peroxisomal parameters were compared after 10 days administration of equal doses (200 mg/kg/day) of cetaben and clofibric acid to male Wistar rats. 3. Clofibric acid treatment increased markedly the activities of FAD-glycerol-3-P dehydrogenase, beta-hydroxyacyl-CoA dehydrogenase, cytochrome-c oxidase, malic enzyme, NAD-glycerol-3-P dehydrogenase, ethoxycoumarin deethylase, p-nitroanisole demethylase and amounts of cytochrome P-450 and b5. 4. However no analogical changes were observed after cetaben treatment in the livers of experimental animals. 5. Both drugs increased the activities of alanine-glyoxylate aminotransferase-1 and acetylcarnitine transferase--enzymes with proven mitochondrial and peroxisomal location. 6. Cetaben contrary to clofibric acid does not increase solubilization of peroxisomal enzymes. 7. Enhanced acetylcarnitine transferase and alanine-glyoxylate aminotransferase-1 activities were distributed in mitochondria as well as in peroxisomes after clofibric acid treatment, however, only peroxisomes were enriched after cetaben administration. 8. The results obtained suggest that cetaben represents an exceptional type of peroxisome proliferator, specifically affecting peroxisomes, without having a negative influence on the processes of peroxisome biogenesis.

Abstract
The effects of cetaben and clofibric acid were compared on the activities of peroxisomal enzymes in the liver and kidney of male Wistar rats. Cetaben at 200 mg/kg body wt increased the activities of all of the enzymes in the liver that were studied two to eight times, whereas the changes induced by the same dose of clofibric acid increased some of the enzymes and decreased others. In the kidney, cetaben increased the activities of all investigated peroxisomal enzymes, while clofibric acid only increased the activity of palmitoyl-CoA oxidase. The data obtained in the dose-response study of cetaben revealed a significant rise in the activities of peroxisomal enzymes in both the liver and kidney at doses of 50-100 mg/kg body wt administered over 10 days, but the maximal effect was observed at 250 mg/kg. Palmitoyl-CoA oxidase and D-amino acid oxidase respond most markedly to cetaben. Cetaben could represent an atypical peroxisomal proliferator, since it increased the activities of all peroxisomal enzymes investigated. The fact that the individual components localized in the peroxisomes do not change markedly could be of importance with respect to the function and physical properties of peroxisomes.

Abstract
A method is described for the determination of the novel hypocholesterolaemic drug, 2-n-octadecylindole-5-carboxylic acid (I) in plasma. A homologue of I is used as the internal standard. Methanol is added to the plasma sample in order to precipitate the plasma proteins, followed by centrifugation and removal of the supernatant. This is reduced to dryness by heating under oxygen-free nitrogen, prior to reconstitution in the chromatographic mobile phase. The solution is assayed by injection on to a 5 micron particle size ODS2 analytical column, protected by a disposable RP-18 packed guard column, using an isocratic mobile phase of acetonitrile-water-isopropyl alcohol-formic acid (75:275:150:2.5, v/v). Detection is by ultraviolet absorbance at 276 nm. At a flow-rate of 1.5 ml min-1 and ambient temperature, the retention time of the drug is 16 min, whilst that for the internal standard is 21 min. This method has been validated and successfully used to assay clinical trial plasma samples. Basic pharmacokinetic parameters are presented.
