Calceolarioside B

Calceolarioside B is a phenylethanoid glycoside. Calceolarioside B can be isolated from the leaves of Akebia quinata. Calceolarioside B inhibits RLAR activity with an IC50 value of 23.99 μM. Calceolarioside B inhibits the entry of Omicron BA.2 into host cells. Calceolarioside B reduces IL-6 levels. Calceolarioside B has immunomodulatory activity. Calceolarioside B has anticancer activity against human hormone-independent prostate cancer[1][2][3][4].
