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]

All Antibiotic Isoforms :

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].

In Vivo

Spectinomycin dihydrochloride (20 mg/kg; i.m.; 20-100 mg/kg; 9 d) shows the safety in healthy chicks^[4].
Spectinomycin dihydrochloride (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].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
