Special Issue Information

Medicinal plants present a valuable source of chemicals with potential therapeutic properties. They are widely used in traditional medicine as supportive therapeutics for various conditions and diseases. In recent years, there have been extensive studies in the area of medicinal plant research dealing with their various pharmacological effects. Novel research on this subject is necessary, since this is a hot topic field. Many in vitro studies describe the beneficial effects of plants for human health, highlighting promising pharmacological effects.

This thematic issue will cover the biological activity of medicinal plants and isolated compounds. Screening natural preparations for their biological activities is of prime importance, since natural raw material presents an excellent source of pharmaceuticals with a wide variety of different biologically active chemical structures.

The scope of the thematic issue will cover but is not limited to:

  • Chemical characterization of natural preparations;
  • Therapeutic potential of natural matrices in cardiovascular diseases, diabetes, cancer, and neurodegenerative diseases;
  • Antimicrobial activity;
  • Antioxidant activity;
  • Anti-enzymatic activity;
  • Anti-inflammatory activity;
  • Mechanism of pharmacological actions;
  • Structure–activity studies.

Additive Effect of a Combination of Artocarpus lakoocha and Glycyrrhiza glabra Extracts on Tyrosinase Inhibition in Melanoma B16 Cells

Artocarpus lakoocha (Al) and Glycyrrhiza glabra (Gg) extracts have been reported to show tyrosinase inhibitory activity and melanin pigment reduction. This is the first study to assess the combination of Al and Gg extracts in enhancing inhibition of tyrosinase and reduction of melanin pigments. Al and Gg extracted by maceration in 70% and 95% ethanol were analyzed for oxyresveratrol and glabridin using Ultra High Performance Liquid Chromatography. Extracts of Al and Gg singly and combinations of Al95 and Gg95 were tested for cytotoxicity, tyrosinase inhibitory activity, and reduction of melanin pigments in melanoma B16 cells. Al95 had higher antioxidant, tyrosinase inhibitory activity and reduced more melanin pigments in B16 cells compared to Al70, and exhibited higher levels of oxyresveratrol. Gg95 inhibited oxidative stress and mushroom tyrosinase better than Gg70, and exhibited higher levels of glabridin. Combinations of Al95 and Gg95 at various ratios (concentration of 0.1 mg/mL) were not cytotoxic to B16 cells. Interestingly, Al95 and Gg95 combined at a ratio 9:1 reduced melanin pigment up to 53% in B16 cells. This combination of Al95 and Gg95 extracts exhibited the additive effect of reducing melanin pigments by suppressing the expression of microphthalmia-associated transcription factor (MITF), tyrosinase (TYR) and tyrosinase-related protein-2 (TRP-2) in B16 cells. The combination of Al and Gg extracts could be developed as skin care products for hyperpigmentation treatment. Full article
