certain conditions using catalytic amounts of mineral acid. It has been found that cis-cis (rccc) and trans-trans (rttt) isomers of C-tetramethylcalixresorcinarene can be synthesized selectively by changing the ratio of water-organic phase, i.e. by changing the polarity of the medium. The reaction products have been separated using semi. Furthermore, Tetramethylkaempferol and pentamethylquercetin also increased mRNA levels of adiponectin, glucose transporter 4 (GLUT4), and fatty acid-binding protein (aP2). Both compounds also increased the mRNA levels of peroxisome proliferator-activated receptor (PPAR)γ2 and CCAAT/enhancer-binding protein (C/EBP)α, β, and/or δ, although.
Theacrine has many other names, such as 1,3,7,9-tetramethyluric acid, Temurin, Temorine, Tetramethyluric acid, Tetramethyl uric acid and with IUPAC name as 1,3,7,9-tetramethylpurine-2,6,8-trione.

The conjugated linoleic acid methyl cis-9,transoctadecadienoate has been prepared on a large scale from methyl ricinoleate. Methyl ricinoleate was purified from castor esters by a partition method. It was converted to the mesylate, which was reacted with a base (1,8-diazabicyclo[5,4,0]-undecene) to give a product that contained 66% of the desired by: Six novel cis/trans-butenedioic acid esters had been synthesized to discover the new bioactive molecules that could kill food-related bacteria and structures were analyzed by melting point, LC–MS, 1 H NMR and 13 C NMR.

Nametkin, G. Shvekhgeimer, V. Tyurin, Kh. Hassan, M. Mavalonov. In chemistry, 2,2,3,3-tetramethylsuccinic acid or 2,2,3,3-tetramethylbutane-1,4-dioic acid is a dicarboxylic acid with the formula C 8 H 14 O 4, or HOOC-C(CH 3) 2-C(CH 3) 2-COOH. It can be seen as derivative of succinic acid (butane-1,4-dioic acid) with two methyl groups replacing two hydrogen atoms on each of the central carbon atoms of the chain.
