Title: Improved native chemical ligation with three or more components
Inventor: VILLAIN MATTEO
IPC: C07K1/02
Filed: 2002-05-31
Abstract: The invention provides a method of assembling oligopeptide intermediates in a native chemical ligation reaction that eliminates self-ligation of bi-functional intermediates. An important aspect of the invention is a bi-functional intermediate with an N-terminal cyclic thiazolidine protecting group which effectively prevents self-ligation in the chemical assembly process. The present invention is useful in methods for convergent synthesis of polypeptides and proteins and improves the efficiency of native chemical ligation reactions, particularly where three or more peptide fragements are used to assemble a polypeptide or protein product.

Abstract: L'invention concerne un raccord de tuyauterie à filetage conique haute résistance, présentant un rapport de changement de rayon par tour sur la modification de la largeur du filetage par tour, tel que ce rapport permet de conserver à la fois un joint fileté et une étanchéité, même lorsque le raccord est soumis à des charges d'exploitation transitoires, telles que les vibrations, les chocs, la courbure, la tension, la compression, la torsion et/ou les changements de température. La forme filetée peut être ouverte ou piégée afin d'être utilisée sur un tuyau de gros ou de petit diamètre; elle peut consister en un joint affleuré; comprendre des colliers d'un diamètre plus grand que celui du tuyau; des raccords à deux chevilles; des raccords pour outils et accessoires; cette forme peut également être utilisée pour raccorder provisoirement des postes de structures solides à des éléments de base pour lesquels une large gamme de couple de vissage répétitif est souhaitée. Les filetages sont faciles à fabriquer et à monter, et ils permettent de réduire les dégâts pouvant être provoqués par les manipulations. Le raccord décrit dans l'invention présente une capacité de couple très élevée sans utilisation d'épaulements; de plus, il peut être soumis à une "accélération de la rotation" répétée et serré sur une large gamme de couple, sans modification significative de la position de vissage finale. Le raccord présente une très grande résistance à la tension, à la compression et à la courbure par rapport au tuyau. Ce raccord peut se présenter dans des configurations haute résistance, telles que des joints affleurés intégrés, des manchons cylindriques presque affleurés, des raccords à deux chevilles, et même des raccords de postes structurels. L'invention concerne également des enduits d'enrobage pour filetage pouvant être utilisés avec un raccord donné.
