生物活性

Helenalin is an anti-inflammatory sesquiterpene lactone. Helenalin selectively inhibits transcription factor NF-κB by directly targeting p65. Helenalin has alkylating activity, targets the cysteine sulfhydryl groups in the p65 subunit of NF-κB, thereby inhibits its DNA binding.

体外研究

Helenalin (10 μM; 20-120 minutes) causes complete inhibition of NF-κB DNA binding after 80 minutes.
The anti-inflammatory, anti-carcinogenic phytochemical, Helenalin is a potent inhibitor of periodic Skp2 accumulation, an F-box protein mediating SCF E3 ligase ubiquitylation and degradation of both CKIs during S phase progression.

The molarity calculator equation
Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)
The dilution calculator equation
Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2
