Carboxy-PTIO potassium
Based on 7 publication(s) in Google Scholar
Carboxy-PTIO potassium is a potent nitric oxide (NO) scavenger that can make a quick reaction with NO to produce NO2. Carboxy-PTIO potassium can prevent hypotension and endotoxic shock through the direct scavenging action against NO in lipopolysaccharide-stimulated rat model.

Actividad biológica
Carboxy-PTIO potassium (200 μM; 1 h prior to physalin A; 24 hours) significantly suppresses the stimulation of NO expression induced by Physalin A (HY-N9942) treatment, but no change is observed in Carboxy-PTIO treatment alone[1].Carboxy-PTIO potassium (200 μM; 1 h prior to physalin A; 24 hours) reduces Physalin A-induced cleavage of procaspase-3 and PARP, down-regulated ICAD expression,diminishing DNA fragmentation in nuclei[1].Carboxy-PTIO potassium (200 μM; 1 h prior to Physalin A; 24 hours) shows no effect on iNOS expression. However, decreased-mTOR and p-mTOR levels induced by Physalin A is reversed by Carboxy-PTIO with concomitant suppression of LC3 I to LC3 II conversions in A375-S2 cells [1].
