Biological Activity
Tumulosic acid displays dose-dependent anti-KLK5 activity (IC50=19.3 μM)[1].
Tumulosic acid decreases in LL-37 production in human keratinocytes[1].
Tumulosic acid shows IC50 values of 14.84 and 10.48 μM against KLK5 and trypsin proteases, while it exhibited a weak inhibitory effect on KLK7 and chymotrypsin C proteases (19.5% and 4.0%, respectively, at 100 μM)[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
