In tissue engineering, survival of larger constructs remains challenging due to limited supply of oxygen caused by a lack of early vascularization. Controlled release of oxygen from small organic molecules represents a possible strategy to prevent cell death under anoxic conditions. A comprehensive study of methylated pyridone-derived endoperoxides has led to the development of water-soluble molecules that undergo retro-Diels-Alder reactions in aqueous environment releasing oxygen in high yield and with half-lives of up to 13 h. These molecules in combination with vitamin C as singlet oxygen quencher significantly improved survival of 3T3 fibroblasts and rat smooth muscle cells challenged with oxygen-depleted conditions.

This report describes the syntheses and structure-activity relationships of 8-(substituted pyridyl)pyrazolo[1,5-a]-1,3,5-triazine corticotropin releasing factor receptor-1 (CRF1) receptor antagonists. These CRF1 receptor antagonists may be potential anxiolytic or antidepressant drugs. This research resulted in the discovery of compound 13-15, which is a potent, selective CRF1 antagonist (hCRF1 IC50 = 6.1 ± 0.6 nM) with weak affinity for the CRF-binding protein and biogenic amine receptors. This compound also has a good pharmacokinetic profile in dogs. Analogue 13-15 is orally effective in two rat models of anxiety: the defensive withdrawal (situational anxiety) model and the elevated plus maze test. Analogue 13-15 has been advanced to clinical trials.
