Mechanism of Action

Pharmacology:

  • Constituents: (3,4-dihydroxyphenyl)-2-ethyl[alpha-L-arabinopyranosyl-(1-->2)-alpha-L- rhamnopyranosyl-(1-->3)]-beta-D-apiofuranosyl-(1-->6)-4-O-caffeoyl-beta-D- glucopyranoside, alyssonoside 5, angoroside A 7, arenarioside, ballotetroside , caffeoyl-L-malic acid, forsythoside B, 13-hydroxyballonigrinolide , lavandulifolioside 6, luteolin-7-lactate, luteolin-7-glucosyl-lactate, phenylpropanoid glycosides, verbascoside.
  • Ballotetroside, a phenylpropanoid glycoside, has been isolated from the aerial parts of Ballota nigra.5 On the basis of chemical and spectral data, its structure has been established as (3,4-dihydroxyphenyl)-2-ethyl[alpha-L-arabinopyranosyl-(1-->2)-alpha-L- rhamnopyranosyl-(1-->3)]-beta-D-apiofuranosyl-(1-->6)-4-O-caffeoyl-beta-D- glucopyranoside.
  • Antibacterial effects: Verbascoside, forsythoside B, and arenarioside isolated from Ballota nigra exhibited a moderate antimicrobial activity against Proteus mirabilis and Staphylococcus aureus including one methicillin-resistant strain.1
  • Antioxidant effects: The ethanol extract of Ballota nigra subsp. anatolica has anti-superoxide anion formation with an IC50 value between 0.50-0.87mg/mL.2
  • Cholesterol effects: Spectrophotometric studies showed that verbascoside, forsythoside B, arenarioside, ballotetroside, and caffeoyl-L-malic acid extracted from Ballota nigra are strong inhibitors of Cu(2+)-induced LDL oxidation, independent of any capacity to act as Cu(2+) chelators.4
  • Neurosedative effects: In a laboratory study using affinity tests with rat striata, entire brains, and receptor rich preparations, four of the five compounds extracted from Ballota nigra (verbascoside, forsythoside B, arenarioside, ballotetroside, and caffeoyl malic acid) were able to bind to benzodiazepine, dopaminergic, and morphinic receptors receptors.3 Inhibitory concentrations at 50% were determined and vary from 0.4-4.7mg/mL.

Pharmacodynamics/Kinetics:

  • The ethanol extract of Ballota nigra subsp. anatolica has anti-superoxide anion formation with an IC50 value between 0.50-0.87mg/mL.2
