Spectinomycin dihydrochloride is a broad-spectrum antibiotic and inhibits the growth of a variety of gram-positive and gram-negative organisms. Spectinomycin dihydrochloride acts by selectively targeting to the bacterial ribosome and interrupting protein synthesis. Spectinomycin dihydrochloride is also a noncompetitive inhibitor of td intron RNA with an K_i value of 7.2 mM^-.

Description

IC₅₀ & Target

bacterial ribosomal subunit^[5]

In Vitro

Spectinomycin dihydrochloride selectively inhibits protein synthesis in cells and in extracts of Escherichia coli:
Spectinomycin dihydrochloride (50 μg/mL) inhibits Escherichia coli growth rapidly and reversibly, and suppresses amino acid incorporation immediately^[1].
Spectinomycin dihydrochloride (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]^[1].
Spectinomycin dihydrochloride 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 dihydrochloride interacts specifically with the residues G1064 and 01192 in 16S rRNA and potentially makes it inactive^[2].
Spectinomycin dihydrochloride exhibits splicing inhibition and dependent on pH changes and Mg²⁺ concentration, indicating electrostatic interactions with the intron RNA^[3].
