描述:

Neomycin sulphate?belongs to a class of antibiotics known as the aminoglycosides. Neomycin sulphate belongs to a class of antibiotics known as the aminoglycosides. Neomycin sulphate is bactericidal in action (kills bacteria). Neomycin sulphate (Neomycin sulphate) does this by causing the bacteria to produce defective proteins which are essential for their growth. Neomycin sulphate is an antibiotic, active against many strains of Gram-positive and Gram-negative bacteria including Staph. aureus, E. coli, Klebsiella spp., H. influenzae, S. typhi, Shigella and Mycobacterium tuberculosis. It is ineffective against fungi and viruses.

溶解性:Water :131 mg/mL (144.1 mM)

体外研究:

Neomycin interacts preferentially with the ribozyme-substrate complex and that this interaction leads to a reduction in the cleavage rate by stabilizing the ground state of the complex and destabilizing the transition state of the cleavage step. Neomycin effects a conformational change in the structure of trans-activating region (TAR) that can be detected by circular dichroism spectroscopy. Neomycin acts as a noncompetitive inhibitor that can bind to the Tat-TAR complex and increase the rate constant (koff) for dissociation of the peptide from the RNA. Neomycin is the most effective aminoglycoside (groove binder) in stabilizing a DNA triple helix. Neomycin stabilizes TAT, as well as mixed base DNA triplexes, better than known DNA minor groove binders (which usually destabilize the triplex) and polyamines. Neomycin shows a preference for stabilization of TAT triplets but can also accommodate CGC(+) triplets. Neomycin induces a concentration- and voltage-dependent partial block from both the cytosolic and luminal faces of the channel. Neomycin has a greater affinity for the luminal site of interaction than the cytosolic site: zero-voltage dissociation constants (Kb(0)) are respectively 210.20 nM and 589.70 nM for luminal and cytosolic block. Neomycin also exhibits voltage-dependent relief of block at holding potentials >+60 mV.
