In Vitro HS-276 reduces expression of TNF, IL-6, and IL-1β in a dose-dependent manner, with IC50 values of 138, 201, and 234 nM, respectively[1].
In Vivo HS-276 (CIA mouse model of inflammatory arthritis, 50 mg/kg, IP, daily for 6 days) reduces inflammation, pannus, cartilage damage (CD), bone resorption (BR), and periosteal bone formation (PBF) histological manifestations[1]. HS-276 (CD-1 mice, 30 mg/kg, Oral gavage, once) shows excellent bioavailability in mice with a Cmax of 3.68 μM and %F of 98.1%[1].
