Enzymatic Deprotection of Methylthiomethyl Esters: Synthesis of O-(Carbamoyl) and O-(Sulfamoyl)salicylic Acids
摘要:
An enzymatic selective deprotection of methylthiomethyl esters via their sulfone derivatives in presence of labile carbamoyloxy as well as sulfamoyloxy functionalities lead to the formation of O-(carbamoyl) and O-(sulfamoyl)salicylic acids respectively.

(EN) The present invention relates to novel salicylate compounds which comprise a salicylate moiety and a biologically active agent of interest, where the compound binds and bonds specifically through reaction of the salicylate ester to serum albumin at Lys 199. Albumin is a long-lived moiety present in the blood. Novel salicylate compounds of the present invention provide for long-lived maintenance of the biologically active entity in the host. These compounds find broad applications in prophylactic and therapeutic applications, production of antibodies, reduction of the biologically effective concentration or activity of an endogenous or exogenous blood component, and in other situations where long term administration of a physiologically active compound is of interest.(FR) La présente invention porte sur de nouveaux composés de salicylate comprenant une fraction de salicylate et un agent biologiquement actif. Le composé s'immobilise et se lie spécifiquement par réaction de l'ester de salicylate à la sérum-albumine au niveau de Lys 199. L'albumine est une fraction de longue durée présente dans le sang. Les nouveaux composés de salicylate de cette invention assurent un maintien de longue durée dans l'hôte de l'entité biologiquement active. Ces composés ont des applications étendues dans les domaines prophylactiques et thérapeutiques, dans la production d'anticorps, la réduction de la concentration ou l'activité biologiquement efficace d'un composant sanguin endogène ou exogène, et dans d'autres situations où l'administration à long terme d'un composé biologiquement actif s'avère importante.
