The spectrum of activity of the antibiotic can be widened when used in combination with SPR741 TFA. Synonyms: NAB741. Grades: >98%. CAS No. 1179330-52-9. Molecular formula: C44H73N13O13. Mole weight: 992.13. | |
| Tyrothricin | Tyrothricin is a cyclic polypeptide-antibiotic mixture from Bacillus brevis. It is a locally effective antibiotic effective against gram-positive bacteria. It is sometimes combined with benzocaine 5mg to provide relief from sore throats. In systemic intake it can lead to severe side effects, therefore, the use is limited to topical application.Tyrothricin belongs to the pharmacologically related group of polypeptide antibiotic compounds including colistin, polymyxin B and bacitracin. There is no cross-resistance to these three agents. Group: Inhibitors. Alternative Names: bactratycin; coltirot; dermotricine; duboscrudecrystals; hydrotricine; intradermtyrothricin; martricin; soluthricin. CAS No. 1404-88-2. Molecular formula: C65H85N11O13. Mole weight: 179.17112. Appearance: Solid. Purity: ≥96.0%. Density: 1.32 g/cm³. Catalog: ACM1404882. |  |
