TH301

TH301 acts as a stabilizer for cryptochrome circadian regulator 2 (CRY2) . It demonstrates selectivity by stabilizing CRY2 over CRY1 in a degradation assay conducted with HEK293 cells expressing CRY reporters at concentrations ranging from 0.1 to 10 μM. In wild-type mouse fibroblasts, TH301 extends the circadian period, but this effect is absent in Cry2-/- fibroblasts. Additionally, it boosts rosiglitazone-dependent induction of brown adipose tissue-specific genes such as Ucp1, Cidea, and Kcnk3 in primary mouse stromal vascular fractions.
