Calycosin (Cyclosin) acts as a selective estrogen receptor modulator. Calycosin induces apoptosis in human ovarian cancer SKOV3 cells by activating caspases and Bcl-2 family proteins. Calycosin suppresses breast cancer cell growth via ERβ-dependent regulation of IGF-1R, p38 MAPK and PI3K/Akt pathways. Calycosin has antineoplastic effects against osteosarcoma through inducing apoptosis showing in vitro and in vivo investigations. Calycosin was shown to induce angiogenesis in human umbilical vein endothelial cell cultures (HUVEC) in vitro. Calycosin may be an effective skin-lightening agent that regulates the expression of melanogenic enzymes. Calycosin exhibited tyrosinase inhibitory activity with an IC(50) value of 38.4 microM.

5-epi-Arvestonate A, a sesquiterpenoid extracted from Seriphidium transiliense whole plants, enhances melanogenic production by stimulating MITF and tyrosinase family gene transcription. Additionally, it suppresses IFN-γ-chemokine expression via the JAK/STAT signaling pathway in HaCaT cells [1].

Tyrosinase-IN-22 (compound 4) serves as a potent inhibitor for tyrosinase substrates, namely L-tyrosine and L-dopa, exhibiting inhibitory concentrations (IC50s) of 60 nM and 30 nM, respectively. Additionally, it demonstrates significant antioxidant and anti-melanogenic properties, making it suitable for related research endeavors [1].
