Cryogenine

Cryogenine is an alkaloid originally isolated from H. salicifolia that has anti-inflammatory activity. It inhibits prostaglandin synthetase (IC50 = 424 µM). Cryogenine (100 mg/kg per day, p.o.) reduces paw edema and the mean arthritic index in a rat model of adjuvant-induced polyarthritis.Formal Name: (4aR,6S,9Z,20S)-2,3,4,4a,5,6-hexahydro-14-hydroxy-17,18-dimethoxy-20H-6,20-methano-11,15-metheno-1H,8H-benzo[g]pyrido[2,1-d][1,5]oxaazacyclohexadecin-8-one.
