background indomethacin is a nsaid (non-steroidal anti-inflammatory drug) that is used in treatment of pain and inflammatory. immediate and sustained release products of this drug have side effects, so a proper replacement is needed. use of the medicine via topical and cutaneous routs has advantages such as avoiding side effects on gastrointestinal; and supplying an amount of medicine in plasma...
losartan potassium is a well known orally active non-peptide angiotensin ii receptor antagonist. losartan potassium and its principle active metabolites block the vasoconstrictor and aldosterone secreting effect of angiotensin ii by selectively blocking the binding of angiotensin ii to at1 receptors. the drug is reported to promote the decrease in ventricular hypertrophy, salt and water excreti...
phorbiaceae. It is a shrub or small tree reaching 4—5 meters high and native to Thailand, where it is commonly called “Plao phae”. In this paper, we describe the isolation and structure elucidation of newly isolated 3 -(4 -hydroxy-3 ,5 dimethoxyphenyl)-propyl benzoate, 3 -(4 -hydroxyphenyl)propyl benzoate and four known compounds [3 -(4 -hydroxy-3 -methoxyphenyl)-propyl benzoate, poilaneic acid...
The objective of this investigation was to find a simple method for the production of phenolic rich products and sugar derivatives (biopolyols) via separation of liquefied lingocellulosic materials. Liquefaction of lignocellulosic materials was conducted in methanol at 180 °C for 15 min with the conversion of raw materials at about 75%. After liquefaction, the liquefied products were separated ...
A series of N-hydroxyformamide tumor necrosis factorconverting enzyme (TACE)/matrix metalloprotease (MMP) inhibitors were evaluated for their potential to induce human cytochrome P450 3A (CYP3A). Two in vitro assays were used: 1) a cell-based reporter gene assay for activation of the pregnane X receptor (PXR), and 2) a primary “sandwich” culture of human hepatocytes. Approximately 50 TACE/MMP i...

Nine compounds, 3-hydroxy-4,5-dimethoxyphenyl-beta-D-glucopyranoside (1), beta-D-fructfuranosyl-alpha-D-(6-vanilloyl)-glucopyranoside (2), beta-D-fructfuranosyl-alpha-D-(6-syringyl)-glucopyranoside (3), 3-hydroxy-1-(4-hydroxy-3-methoxyphenyl)-2-[4-(3-hydroxy-1-(E)-propenyl)-2-methoxyphenoxy]propyl-beta-D-glucopyranoside (4), 3-hydroxy-1-(4-hydroxy-3-methoxyphenyl)-2-[4-(3-hydroxy-1-(E)-propenyl...
ME T H Y L N P R O P Y L ETHER is an isomer of di-ethyl ether and possesses the formula CHs-O(CHI)J-CHJ. The physical properties of the two drugs are similar, and the vapour pressure curve of methyl-n-propyl ether is such that it may be used in the Oxford Vaporizer No. 1 without any alteration in the calibration of the instrument (see Figure). Methyl-n-propyl ether has a very unpleasant pungent...
