Novel Quinolylnitrones Combining Neuroprotective and Antioxidant Properties.

We describe here the preparation, neuroprotective analysis, and antioxidant capacity of 11 novel quinolylnitrones (QN). The neuroprotective analysis of QN1-11 in an oxygen-glucose deprivation model, in primary neuronal cultures, has been determined, allowing us to identify QN6 as a very potent neuroprotective agent, showing significant high value at 0.5 and 10 μM (86.2%), a result in good agreement with the observed strong hydroxyl radical scavenger of QN6.
