Antibacterial aminoglycosides with a modified mode of binding to the ribosomal-RNA decoding site

TL;DR: Antibacterial aminoglycosides with a modified mode of binding to the ribosomal-RNA decoding site and their application in drug discovery and development is described.
Journal ArticleDOI

Structure-Based Design, Synthesis, and A-Site rRNA Cocrystal Complexes of Functionally Novel Aminoglycoside Antibiotics: C2'' Ether Analogues of Paromomycin

TL;DR: In this paper, a series of 2 O-substituted ether analogues of paromomycin were prepared based on new site-selective functionalizations, and X-ray cocrystal complexes of several such analogues revealed a new mode of binding in the A-site rRNA, whereby rings I and II adopted the familiar orientation and position previously observed with paromycin, but rings III and IV were oriented differently.
Journal ArticleDOI

Crystal structure of the bacterial ribosomal decoding site complexed with a synthetic doubly functionalized paromomycin derivative: a new specific binding mode to an a-minor motif enhances in vitro antibacterial activity.

TL;DR: Improved antibacterial activity supports the conclusion that analogue 1 might affect protein synthesis on the ribosome in two different ways: 1) specific binding to the A site forces maintenance of the “on” state with two bulged out adenines, and 2) a new binding mode of 1 to an A‐minor motif which stabilizes complex formation between the Ribosome and the mRNA–tRNA complex regardless of whether the codon–anticodon stem is of the
Journal ArticleDOI

Inhibition of aminoglycoside-deactivating enzymes APH(3')-IIIa and AAC(6')-Ii by amphiphilic paromomycin O2''-ether analogues.

TL;DR: The future of these antibiotics will eventually be compromised by the emergence of bacterial resistance, and in order to overcome this threat to human health, the structures of some other classes of antibiotics have also been substantially modified.
