Abstract:
La présente invention concerne un procédé de synthèse de dithiocarbamates ou bis dithiocarbamates de glycérol (DTCGs) dans lequel, dans un milieu réactionnel comportant (1) un carbonate choisi parmi ie diéthylcarbonate, le diméthylcarbonate, ou le carbonate d'éthylène ou de propyiène associé à un polyol du type glycérol en présence d'un catalyseur basique ou (2) un carbonate cyclique à cinq chaînons, en milieu solvant, on ajoute une aminé primaire ou secondaire en présence de sulfure de carbone, et on récupère le DTCG formé. En particulier, un polyol du type glycérol est mis en présence de diéthylcarbonate, en présence d'un catalyseur, puis on ajoute au milieu réactionnel une aminé primaire ou secondaire en présence de sulfure de carbone, et on récupère le DTCG formé. L'invention permet de synthétiser en une seule étape des dithiocarbamates de glycérol directement à partir du glycérol comme matière première et solvant. Ce procédé fait intervenir le glycérol, du diéthylcarbonate, du disulfure de carbone (CS2) et une aminé primaire ou secondaire pour conduire aux dithiocarbamates de glycérol, la phase glycérol/NaOH ayant pu être recyclée 6 fois sans perte notable de rendement, l'acétate d'éthyle étant également recyclé après chaque extraction.
Abstract:

Abstract:
The invention provides novel thiocarbamate alpha-4 inhibitors of the general formula (I) wherein L is -C(S)-O- or -C(O)-S-; that are resistant to metabolism having improved half-life and/or clearance properties compared to corresponding carbamate compounds wherein substituents L, X, Y, Z, R -R , m, n, o and p are as defined herein. Also provided are compositions comprising compounds of formula I and a carrier, diluent or excipient as well as methods of treating a disease or condition mediated by the binding interaction of alpha-4 integrins to its ligands such as inflammatory diseases.
Abstract:
Disclosed are diaryl piperazines and related compounds. These compounds are selective modulators of capsaicin receptors, including human capsaicin receptors, that are, therefore, useful in the treatment of a chronic and acute pain conditions, itch and urinary incontinence. Methods of treatment of such disorders and well as packaged pharmaceutical compositions are also provided. Compounds of the invention are also useful as probes for the localization of capsaicin receptors and as standards in assays for capsaicin receptor binding and capsaicin receptor mediated cation conductance. Methods of using the compounds in receptor localization studies are given.
