Page/Page column 8; 12, (2009/01/23)
Novel biaromatic compounds that modulate peroxisome proliferator-activator receptors, known as PPAR, having the formula (I): are formulated into pharmaceutical compositions useful in human or veterinary medicine, or alternatively, in cosmetic compositions.
CHROMOIONOPHORE AND METHOD OF DETERMINING CALCIUM IONS
-
, (2008/06/13)
The invention relates to methods of determining calcium ions in a sample, wherein the ions are contacted with a compound having chromophoric moiety and an ionophoric moiety, where the ionophoric moiety interacts with the calcium ions present in the sample, resulting in the chromophoric moiety changing its radiation absorption properties in the ultraviolet and visible regions of the spectrum. For example, a change in an intensity of an absorption maximum is measured and the ion concentration is determined accordingly.

A novel biocatalytic approach for the large-scale production of S-2-ethoxy-3-(4-hydroxyphenyl)propanoic acid S-1 from its racemic ethylester rac-2 by enantioselective hydrolysis has been developed. S-1 is an important building block in the synthesis of PPARα and -γ agonists such as Ragaglitazar [NNC 61-0029 ((-)DRF2725)]. The development history comprises enzyme screening, biocatalyst and process optimization, and scale-up to pilot plant. The project was thereby highly interdisciplinary by combining biotechnology and chemistry technologies. The final process was successfully run on a 44-kg pilot scale in 43-48% yields and with high enantiomeric purities (98.4-99.6% ee).

The principles of 1,2-cyano-hydroxylation of olefins were applied to the preparation of 1,2-cyano-amines.The dipole component of this cycloaddition was nitrile imines, which formed pyrazolines with olefins.Ring cleavage was accomplished by thermolysis of 3-carboxypyrazolines, which gave 1,2-cyano-amines and subsequent hydrolysis gave β-amino acids.The synthesis of the title reagents were described.Ethyl 2-chloro-2-ethoxy-acetate gave selectively oximes, hydrazones, nitrones, and phosphonium salts with hydroxylamine, hydrazines, N-substituted hydroxylamines and triphenylphosphine respectively.The phosphonium salt was used in a Wittig reaction with aldehydes to give α-ketoesters.Treatment of the acid chloride with allyl alcohols and subsequently with a monosubstituted hydroxylamine gave the allylic ester nitrone, which underwent intramolecular cyclization.Similarly, intramolecular cyclization were carried out with the allylic ester - nitrile oxime and allylic ester - nitrile imine systems.
