Detailed Research Description

  1. Biologically active compounds from natural sources: Natural products were and are still a rich source for drug discovery. One challenge is the rediscovery of known compounds. To avoid replication, Cao Lab is interested in studying the under-explored microorganisms in Hawaii. (i) The distribution and biologically active compounds of marine fungi have not been well studied compared with their counterparts in freshwater and terrestrial ecosystems. Few studies have addressed the occurrence of fungi in deep-sea sediments. Studies also showed that taxonomic and functional annotation of the transcriptome demonstrated that coral-associated fungi in Hawaii represent a diverse and metabolically active community, indicating that there is much to learn about fungi in corals. (ii) A total of 23,680 Hawaiian species have been documented, including 18,607 native Hawaiian species (9,151 indigenous species and 9,456 endemic species), and 5,073 human-introduced (non-native) species. Among the formally recognized species of native Hawaiian flowering plants, 88.9% are endemic to the Hawaiian islands. Research in the past ten years reveals that endophytic fungi are a rich source of biologically active secondary metabolites, but endophytic fungi are much underexplored. (iii) Bacteria, particularly actinimycetes, were traditionally the main source for drug discovery, especially for antibiotic. Many efforts have been focusing on discovering new drugs from old sources (for example, streptomyces), but it usually leads to the discovery of known natural products. More recently, efforts have been taken to reveal the cryptic natural products based on their unique genomic signatures. New technology enables scientists to study bacteria from new sources (for example, cyanobacteria, myxobacteria, uncultured bacteria, bacteria in lower animals, insects-associated bacteria, and bacteria from marine etc); and these adventures have resulted in the discovery of novel bioactive compounds with unique structural skeletons. Also, globally and locally remote, as well as physically and chemically diverse, Hawaiian aquatic habitats provide unique niches for the evolution of novel communities and microorganisms. Cao Lab is interested in finding new anticancer (& antibacterial and anti-fungal, etc.) natural products from marine and terrestrial fungi and bacteria collected in Hawaii, manipulating silent genes for the production of secondary metabolites, understanding how they are biosynthetically synthesized, and elucidating their mechanisms of action. Since the end of 2013, Cao Lab has published more than ten papers about anti-proliferative compounds, p53 reactivator, STAT3 & NF-kB inhibitors, and antibacterial & anti-fungal agents from Hawaiian fungi in “Org. Lett.”, “Sci. Rep.”, “Phytochemistry”, “Bioorg. Med. Chem. Lett.”, “Tetrahedron Lett.”, “Molecules”, and “Cancer Biol.” etc.
  2. Herbal medicine: Herbal medicine has a long history, which is still used in many countries. Although herbal medicine is not part of the mainstream medical care in the USA, FDA has approved two botanic drugs, and will likely approve more. One challenge to study herbal medicine is the identification of biologically active molecules that account for the claimed therapeutic effects and mechanisms of action. Cao Lab is interested in studying traditional medicine used in the Asia-Pacific Region. In the past few years, Cao Lab has been studying some medicinal plants including Barleria lupulina and Morinda citrifolia. From these plants, Cao Lab has isolated many new compounds, identified a few previously unknown Nrf2 activators, and published some papers in “PLoS ONE”, “J. Ethnopharmacol.”, “J. Nat. Prod.”, “Tetrahedron Lett.”, “Bioorg. Med. Chem. Lett.”, and “J. Nat. Sci.” etc.
