Abstract:
The invention relates to novel derivatives of short-chain fatty acids, in particular derivatives of butyric acid, useful for all the known clinical applications of the latter, which show physicochemical characteristics suitable for an easy oral administration, being devoid of the unpleasant organoleptic properties that characterise butyrate. The new compounds are amide derivatives which can be synthesised by reaction of the corresponding fatty acid halide with a naturally occurring amino acid, phenylalanine or a suitable derivative thereof, and which are in a poorly hygroscopic, easily weighable form, stable to acids and alkalis and able to release the acid at the small and large bowel level in a constant manner over time. They do not have disagreeable odours and are practically tasteless, thus allowing the manufacture of preparations for oral administration also suitable for the therapy of chronic diseases and in the paediatric field.

Abstract:
An N-acyl-N-phenyltetrahydrophthalamic acid derivative represented by general formula (I), a process for producing the same, and a herbicide containing the same as the active ingredient: wherein X and Y represent each independently hydrogen or halogen; R1 represents hydrogen, halogen, lower alkoxy, lower alkenyloxy, lower alkynyloxy, lower alkoxyalkoxy or lower alkoxycarbonylalkoxy; R2 represents lower alkyl, halogenated lower alkyl, or (un)substituted phenyl; and R3 represents lower alkoxy, lower alkenyloxy, lower alkynyloxy, lower alkoxyalkoxy, benzyloxy, or lower alkoxycarbonylalkoxy. The herbicide is widely applicable to upland fields, paddy fields, orchards, pastures, turfs, forests, non-crop lands and so forth, and is highly safe to crops, thus proving very useful.
Abstract:
The present invention provides a system for evaporating a radioactive fluid, a method for the synthesis of a radiolabelled compound including this system, and a cassette for the synthesis of a radiolabelled compound comprising this system. The present invention provides advantages over known methods for evaporation of a radioactive fluid as it reduces drastically the amount of radioactive gaseous chemicals that are released in the hot cell. It is gentler and more secure compared to the known process and provides access to radiosyntheic processes that may not been acceptable for safety reasons related to release of volatile radioactive gases during evaporation. In addition, the process yields are higher because the radioactive volatiles are labelled intermediate species.

Abstract:
The present invention relates to organic activators having the following general formula (I): wherein R 1 is a substituted or unsubstituted alkyl or aryl moiety comprising at least five carbons, R 2 is a substituted or unsubstituted alkyl moiety comprising less than five carbons, R 3 is a suitable bridging moiety, R 4 is a charged moiety, N is nitrogen, each G is, independently, an oxygen containing moiety and Z, when present, is a charge balancing counter ion. The present invention also relates to cleaning compositions comprising said organic activators, and processes for making and using the aforementioned organic activators and cleaning compositions.
Abstract:
The present invention provides a simplified method for the preparation of F-labelled compounds that is particularly suitable for automation. The method of the invention is specifically applicable where the 18 F-labelled compound is prepared from a labelling precursor that comprises protecting groups and wherein the synthetic route to the final compound includes removal of these protecting groups by acid or alkaline hydrolysis. Also provided by the present invention is a cassette useful for carrying out the method of the invention in an automated manner.
