Design and synthesis of boronic acid inhibitors of endothelial lipase
摘要:
Endothelial lipase (EL) and lipoprotein lipase (LPL) are homologous lipases that act on plasma lipoproteins. EL is predominantly a phospholipase and appears to be a key regulator of plasma HDL-C. LPL is mainly a triglyceride lipase regulating (V)LDL levels. The existing biological data indicate that inhibitors selective for EL over LPL should have anti-atherogenic activity, mainly through increasing plasma HDL-C levels. We report here the synthesis of alkyl, aryl, or acyl-substituted phenylboronic acids that inhibit EL. Many of the inhibitors evaluated proved to be nearly equally potent against both EL and LPL, but several exhibited moderate to good selectivity for EL. (C) 2011 Elsevier Ltd. All rights reserved.
Imidamide (amidine) analogs that can inhibit the activity of sphingosine kinase 1 and sphingosine kinase 2 (SphK1 & SphK2) are provided. The compounds can prevent angiogenesis in tumors.
The invention relates to compounds of Formula (I). Compounds of the present invention are inhibitors of sphingosine kinase 3, and are useful in the treatment of various disorders and conditions, such as inflammatory disorders.

Disclosed are a process for producing a porous stretched article of β-crystalline polypropylene-based resin, the process comprising the steps of crystallizing a melt of a polypropylene-based resin composition at a temperature of 15 to 140°C to form a solidified product containing β-form crystals and stretching the resulting solidified product at a temprature which is higher than 20 °C but lower than the melting point of the β-form crystals in said solidified product, the polypropylene-based resin composition comprising a polypropylene-based resin and 0.0001 to 5 parts by weight, per 100 parts by weight of the polypropylene-based resin, of at least one specific amide compound; and a porous stretched article produced by the process.
In a thermal recording sheet having a thermal recording layer containing a colorless or pale colored dye precursor and a color developer reactable with the dye precursor upon heating to develop a color, a dimerized or trimerized urea compound is used as the color developer to obtain a thermal recording sheet which is superior in ground color stability and a thermal recording sheet having a reversible recordability.
