Liverworts-potential source of medicinal compounds

Area of Science:

• * Plant biochemistry and natural product chemistry.
• * Focus on bryophytes, specifically liverworts (Marchantiophyta).

Background:

• * Bryophytes, including liverworts, mosses, and hornworts, are non-vascular plants.
• * Liverworts possess unique cellular oil bodies.
• * These organisms synthesize a wide array of secondary metabolites.

Purpose of the Study:

• * To review the isolation and chemical structures of biologically active compounds from liverworts.
• * To summarize the total synthesis of these compounds.
• * To highlight the diverse biological activities exhibited by liverwort-derived natural products.

Main Methods:

• * Literature review of published research on bryophyte natural products.
• * Analysis of chemical structures and isolation techniques.
• * Examination of synthetic routes for key compounds.

Main Results:

• * Liverworts produce terpenoids, aromatic compounds, and acetogenins.
• * These compounds exhibit a broad spectrum of biological activities: allergenic contact dermatitis, insecticide, insect antifeedant, cytotoxic, piscicidal, muscle relaxing, plant growth regulatory, anti-HIV, DNA polymerase beta inhibitory, anti-obesity, neurotrophic, NO production inhibitory, antimicrobial, and antifungal.
• * Numerous compounds have been isolated, their structures elucidated, and some have undergone total synthesis.

Conclusions:

• * Liverworts are a rich source of structurally diverse natural products with significant pharmacological potential.
• * The identified compounds offer promising leads for drug discovery and development.
• * Further research into bryophyte chemistry and bioactivity is warranted.
