Mad1 (6-21) is a peptide fragment derived from the Mad1 protein, specifically encompassing residues 6 to 21. This fragment exhibits binding affinity towards the mammalian Sin3A PAH2 domain, with a Kd value of approximately 29 nM.
Dalbergioidin exhibits tyrosinase inhibitory activity with an IC50 of 20 mM. It shows a melanin biosynthesis inhibition zone in the culture plate of Streptomyces bikiniensis that has commonly been used as an indicator organism. Dalbergioidin protects MC3T3-E1 osteoblastic cells against H2O2-induced cell damage through activation of the PI3K AKT SMAD1 pathway, suggests that it may be useful in bone metabolism diseases, particularly osteoporosis. Dalbergioidin also ameliorates doxorubicin-induced renal fibrosis by suppressing the TGF-β signal pathway.
