| 英文名称 | Nitrocefin |
| 别名 | 头孢硝噻吩 |
| 英文别名 | Nitrocefin;(6R,7R)-3-[(1E)-2-(2,4-dinitrophenyl)ethenyl]-8-oxo-7-[(2-thienylacetyl)amino]-5-thia-1-azabicyclo[4.2.0]oct-2-ene-2-carboxylic Acid; [6R-[3(E),6α,7β]]-3-[2-(2,4-dinitrophenyl)ethenyl]-8-oxo-7-[(2-thienylacetyl)amino]-5-thia-1-azabicyclo[4.2.0] |
| 应用 | Nitrocefin is a chromogenic β-lactamase substrate that undergoes colour change from yellow to red as the amide bond in the β-Lactam ring is hydrolyzed by β-lactamase. Nitrocefin undergoes colour changes induced by lactamases produced by Gram-positive and Gram-negative bacteria. Several studies have utilized the colour changing properties of Nitrocefin for the detection of β-lactamase activity from bacterial cell extracts by isoelectric focusing and spectroscopy. Nitrocefin has also been used in studies involving β-lactamase resistant antibiotics. |
