Production of peptides in known as "peptide synthesis", in organic chemistry. However, these organic compounds contain multiple amino acids which are bound together via "peptide" bonds; also known as amide bonds. Synthesis of peptides involves the coupling of carboxyl group or C-terminus of one amino acid to the amino group or N-terminus of another amino acid…
Polymerization is a common reaction, due to excessive use of amino acids to ensure coupling during each synthesis phase. As a result, a series of deprotection phases are added to the synthesis process which takes the following form:
t- Boc protecting group: This group requires more number of acid stable groups for side chain protection in orthogonal strategies. It was most commonly used to protect the terminal amine of the peptide being synthesized. This group can be added to amino acids with t-Boc anhydride and a suitable base. It reduces aggregation of peptides during synthesis.
Fmoc protecting group: It is currently being most widely used in the iterative synthesis of a peptide from amino acid units. It is usually removed from the N-terminus of the peptide during iterative synthesis. It is also cleaved under very mild basic conditions and is stable under acidic conditions. Fmoc group is preferred over BOC due to ease of cleavage, but it is less atom-economical.
Nucleoside analogs are replications of natural nucleosides. They prevent the production of new virus, when incorporated into virus DNA or RNA, during virus replication. The nucleoside analogues replace the natural nucleosides to block the completion of the viral DNA chain when they infect a new cell by HIV. ...
