摘要:
Novel acid-labile tris(alkoxy)benzyl ester handles for use in linking protected amino acid or peptides to a support during peptide synthesis are disclosed. Methods for producing the handles, for linking them to solid support resins and for using the resin-linked handles in peptide synthesis are disclosed.
摘要:
The invention relates to indolesulfonyl halogenides which are useful for the protection of organic compounds comprising at least one guanidino moiety and/or at least one amino group. The invention further relates to a process for their preparation and their use as protecting reagents. The invention also relates to the process for the protecting reaction and to the protected compounds thereof.
摘要:
Pramlintide, a peptide having the 37 amino acid sequence KCNTATCATQRLANFLVHSSNNFGPILPPT-NVGSNTY-NH2 is prepared via a convergent three-fragment synthesis strategy from the fragments comprising the amino acid residues 1-12, 13-24 and 25-37, respectively.
摘要:
Novel iminium-type coupling agents containing proton acceptors in their iminium moiety, which can be used beneficially as coupling agents in various chemical polypeptide and/or polynucleotide syntheses, and are particularly useful as yield enhancing and racemization suppressing coupling agents for use in peptide syntheses, are disclosed. Further disclosed are a process of preparing such iminium-type coupling agents and their use in the preparation of polypeptides and/or polynucleotides.
摘要:
Antitumoral compounds of Formula I, and pharmaceutically acceptable salts, derivatives, tautomers, prodrugs or stereoisomers thereof useful as antitumour agents.
摘要:
A mammalian expression vector that is a murine CMV promoter and the first intron of the major immediate early gene of the human cytomegalovirus. There are mammalian host cells containing the expression vector. There is also a process for the production of recombinant protein by using the expression vector.
