This type of antibiotic holds the promise of self-destruction over a number of hours of exposure to light, so that it would not allow selection of resistance in the environment. (4) (5) The synthesis and inhibitory activity toward human leukocyte elastase of new 7α-methoxy and 7α-chloro...
The oxidation number of an atom in a compound or in its pure state is its charge when it becomes an ion. This is the value that is the main concern in a redox reaction. It is the one monitored because the corresponding change in this value will mean that the chemical species undergoes...
