摘要:Novel processes towards the synthesis of the antiviral valomaciclovir stearate in which an esterified guanine acetal is reduced to the corresponding alcohol, reacted with an activated amino acid and N-deprotected. The esterified guanine acetal is prepared from a 9-guanine derivative bearing an acyclic hydroxymethylbutylacetal. The processes are amendable to one-pot reactions.

摘要:A process of regiospecific synthesis of N-9 purine nucleoside analogs in either solution or solid phase synthesis is described. The introduction of the sugar moiety or its analogue on to a 6-heteroarylium purine or its mesomeric betaine so that formation of only the N-9 position regioisomers of the purine nucleoside analogs (either D or L enantiomers) is obtained. This regiospecific introduction of the sugar moiety allows the synthesis of purine nucleoside analogs in high yields without formation of the N-7-positional regioisomers, while the 6-heteroaryliums are leaving groups facilitated for nucleophilic displacement. Solid supported 6-heterarylium purine bases can be used for purine based library synthesis and synthesis of nucleotide monophosphates and polyphosphates. Processes for providing novel 6-heteroarylium purines and their corresponding mesomeric betaines for the regiospecific synthesis of N-9 purine nucleoside analogs and nucleotides are described.

摘要:A method of producing a monomer of a Shiga toxin B-subunit (STxB) protein or of a variant thereof by peptide chemical synthesis, as well as to a method of producing a pentamer of the STxB protein or of the variant thereof. The methods are particularly advantageous as they overcome major issues typically observed in peptide chemical synthesis, including solubility and purity issues.
