Spectinomycin sulfate hydrate
Based on 3 publication(s) in Google Scholar
Spectinomycin sulfate hydrate is a broad-spectrum antibiotic and inhibits the growth of a variety of gram-positive and gram-negative organisms. Spectinomycin sulfate hydrate acts by selectively targeting to the bacterial ribosome and interrupting protein synthesis. Spectinomycin sulfate hydrate is also a noncompetitive inhibitor of td intron RNA with an Ki value of 7.2 mM-.

Biological Activity
Spectinomycin sulfate hydrate selectively inhibits protein synthesis in cells and in extracts of Escherichia coli:
Spectinomycin sulfate hydrate (50 μg/mL) inhibits Escherichia coli growth rapidly and reversibly, and suppresses amino acid incorporation immediately[1].
Spectinomycin sulfate hydrate (1 μg/mL or 3 μM) inhibits polypeptide synthesis directed either by endogenous messenger RNA or by MS-2 bacteriophage RNA, with maximum inhibition of 70-80% in extracts of Escherichia coli[1].
Spectinomycin sulfate hydrate blocks the translocation of peptidyl-tRNAs from A-site to P-site by inhibiting the binding of elongation factor G to the ribosome[2].
Spectinomycin sulfate hydrate interacts specifically with the residues G1064 and 01192 in 16S rRNA and potentially makes it inactive[2].
Spectinomycin sulfate hydrate exhibits splicing inhibition and is dependent on pH changes and Mg2+ concentration, indicating electrostatic interactions with the intron RNA[3].

Spectinomycin dihydrochloride pentahydrate (10 mg/kg; i.v.; single dose) has the major elimination pathway by renal excretion, approximately 55% is excreted into the urine in unchanged form[5].
