1H-Pyrazolo-[3,4-b]pyridine-4-carboxylic acid (I) has been previously reported as an agonist of human peroxisome proliferator-activated receptor alpha (hPPARα). Here, a series of 1H-pyrazolo-[3,4-b]pyridine-4-carboxylic acid derivatives has been prepared in order to examine the structure-activity relationships (SAR). SAR studies clearly indicated that the steric bulkiness of the substituent on 1H-pyrazolo-[3,4-b]pyridine ring, the position of the distal hydrophobic tail part, and the distance between the distal hydrophobic tail part and the acidic head part are critical for hPPARα agonistic activity. These SAR results are somewhat different from those reported for fibrate-class hPPARα agonists. A representative compound (II) was as effective as fenofibrate in reducing the elevated plasma triglyceride levels in a high-fructose-fed rat model. In the experiment, the researchers used many compounds, for example, Methyl2-methylbutyrate (cas: 868-57-5Safety of Methyl2-methylbutyrate).
Methyl2-methylbutyrate (cas: 868-57-5) belongs to esters. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. Liquid esters of low volatility serve as softening agents for resins and plastics. Esters also include many industrially important polymers. Polymethyl methacrylate is a glass substitute sold under the names Lucite and Plexiglas; polyethylene terephthalate is used as a film (Mylar) and as textile fibres sold as Terylene, Fortrel, and Dacron.Safety of Methyl2-methylbutyrate
