2020 FDA TIDES (Peptides and Oligonucleotides) Harvest.

ABSTRACT: 2020 has been an extremely difficult and challenging year as a result of the coronavirus disease 2019 (COVID-19) pandemic and one in which most efforts have been channeled into tackling the global health crisis. The US Food and Drug Administration (FDA) has approved 53 new drug entities, six of which fall in the peptides and oligonucleotides (TIDES) category. The number of authorizations for these kinds of drugs has been similar to that of previous years, thereby reflecting the consolidation of the TIDES market. Here, the TIDES approved in 2020 are analyzed in terms of chemical structure, medical target, mode of action, and adverse effects.

Project description:The complete Haemophilus influenzae genome (1.83 Mb, Rd strain) provides opportunities for characterizing global genomic inhomogeneities and for detecting important sequence signals. Along these lines, new methods for identifying frequent words (oligonucleotides and/or peptides) and their distributions are applied to the H.influenzae genome with some comparisons and contrasts made with frequent words of other bacterial genomes. Three major classes of frequent oligonucleotides stand out: (i) oligos related to the familiar uptake signal sequences (USSs), AAGTGCGGT (USS+) and its inverted complement (USS-), (ii) multiple tetranucleotide iterations and (iii) intergenic dyad sequences (ISDs) found as AAGCCCACCCTAC and its dyad form. The USS+ and USS- occur in almost equal counts, are remarkably evenly spaced around the genome, and appear predominantly in the same reading frame of protein coding domains (USS+ translated to Ser-Ala-Val, USS- translated to Thr-Ala-Leu). These observations suggest that USSs contribute to global genomic functions, for example, in replication and/or repair processes, or as membrane attachment sites, or as sequences helping to pack DNA. The long tetranucleotide iterations, virtually unique to H.influenzae (i.e., unknown in other prokaryotes), through polymerase slippage during replication and/or homologous recombination may produce subpopulations expressing alternative proteins. The 13 bp frequent IDS words, invariably intergenic, occur mostly in clusters and provide potential for complex secondary structures suggesting that these sequences may be important signals for regulating the activity of their flanking genes. The frequent oligopeptides of H.influenzae are principally of two kinds--those induced by oligonucleotide frequent words (USSs, tetranucleotide iterations), and those associated with ATP or GTP binding sites that are generally composed of three motifs: the A-box which contributes to delineating the binding pocket; the B-box which functions in hydrolysis; and the C-box whose function is unknown. The A-box occurs fairly universally in prokaryotes and eukaryotes. The B- and C-motifs appear to be specialized to various functional groups (e.g., transport, recombination, chaperone activity). Other putative motifs correspond to homologs of Escherichia coli motifs, for example, are associated with proteins of transcriptional processing, aminoacyl-tRNA synthetases and proteins functioning in electron transfer.
