Hygromycin B
Hygromycin B is a selective antibiotic.
Antibiotics are a type of antimicrobial used in the treatment and prevention of bacterial infection.
Hygromycin B is an antibiotic that is effective on most bacteria, fungi and higher eukaryotes. Hygromycin B has a single binding site within the 30S subunit, which is in consistent with its monophasic effect. The binding site is located in the major groove of the helix with a highly sequence-specific way. Hygromycin B inhibits protein synthesis by inhibiting the translocation step of elongation and causing mistranslation of mRNA in the 70S ribosome [1]. Hygromycin B selectively inhibited activity of the ribosomal ATPase (RbbA) on 70S ribosomes and releases RbbA from 70S ribosomes at physiological concentrations. RbbA enhances the reactivity of A889 and G890 of the 16S rRNA switch helix region. Also, Hygromycin B protects G1494 and A1408 in the decoding region.

| Cell experiment:[1] | |
| Cell lines | Mouse L cells |
| Reaction Conditions | 200 μg/ml hygromycin B for 2 ~ 6 weeks |
| Applications | Hygromycin B was used for resistance selection in mouse L cells transfected withEscherichia coli genes coding for resistance to the aminocyclitol antibiotics hygromycin B. |
| Animal experiment:[2] | |
| Animal models | Four-week-old BALB/c mice susceptible to MHV-A59 infection |
| Dosage form | 0 ~ 10 μmol/kg Intraperitoneal (i.p.) injection |
| Applications | A single injection of hygromycin B reduced the number of lesions in the livers of MHV-A59-inoculated mice. Higher doses of the drug appeared to be slightly more effective at reducing virus-induced lesions. |
