| Mechanism of Action | Quetiapine Fumarate is a dibenzothiazepine with antagonist activity at dopamine (D1, D2, D3) and serotonin (5-HT1A and 5-HT2) receptors. It also antagonizes adrenoreceptors (alpha 1A, alpha 1b, alpha 2) and histamine receptor (H1). |
| Eukaryotic Cell Culture Applications | Quetiapine was found to alleviate oxidative stress in PC12 cells, leading to higher cell viability and a lower rate of apoptosis. These studies give new insight into the link between oxidative stress and pathophysiology of schizophrenia and Alzheimer's (Wang et al, 2005). |
| Molecular Formula | C21H25N3O2S · 0.5C4H4O4 |
| Solubility | Slightly soluble in DMSO and DMF. slightly soluble in water. |
