TARGET -> INHIBITOR
Helenalin selectively alkylates p65 subunit at Cys38 [27, 63]. Formation of this covalent bond sterically prevents the p50/p65 heterodimer from binding to DNA and therefore inhibits its transcriptional activation.
TARGET -> INHIBITOR
PARENT -> ACTIVE CONSTITUENT ALWAYS PRESENT
TARGET -> INHIBITOR
Helenalin binds to Cys445 of telomerase in the Michael-type addition reaction, disturbing recognition of the telomere DNA at the telomerase active site and causing suppression of the enzyme activity.
