Plants and fungi have provided, or inspired, key pharmaceuticals for global health challenges, including cancer, heart disease, dementia, and malaria, and are valued as traditional medicines worldwide. Global demand for medicinal plants and fungi has threatened certain species, contributing to biodiversity loss and depletion of natural resources that are important for the health of humanity. We consider the evolving role of plants and fungi in global healthcare as new challenges to human health and to biodiversity arise. We present current and emerging scientific approaches, to uncover and preserve nature‐based health solutions for the future, through harmonization with biodiversity conservation strategies.
For some professionally, vocationally,
or technically oriented
careers, curricula delivered in higher education establishments may
focus on teaching material related to a single discipline. By contrast,
multidisciplinary, interdisciplinary, and transdisciplinary teaching
(MITT) results in improved affective and cognitive learning and critical
thinking, offering learners/students the opportunity to obtain a broad
general knowledge base. Chemistry is a discipline that sits at the
interface of science, technology, engineering, mathematics, and medicine
(STEMM) subjects (and those aligned with or informed by STEMM subjects).
This article discusses the significant potential of inclusion of chemistry
in MITT activities in higher education and the real-world importance
in personal, organizational, national, and global contexts. It outlines
the development and implementation challenges attributed to legacy
higher education infrastructures (that call for creative visionary
leadership with strong and supportive management and administrative
functions), and curriculum design that ensures inclusivity and collaboration
and is pitched and balanced appropriately. It concludes with future
possibilities, notably highlighting that chemistry, as a discipline,
underpins industries that have multibillion dollar turnovers and employ
millions of people across the world.
Fungal-derived drugs include some of the most important medicines ever discovered, and have proved pivotal in treating chronic diseases. Not only have they saved millions of lives, but they have in some cases changed perceptions of what is medically possible. However, now the low-hanging fruit have been discovered it has become much harder to make the kind of discoveries that have characterised past eras of fungal drug discovery. This may be about to change with new commercial players entering the market aiming to apply novel genomic tools to streamline the discovery process. This review examines the discovery history of approved fungal-derived drugs, and those currently in clinical trials for chronic diseases. For key molecules, we discuss their possible ecological functions in nature and how this relates to their use in human medicine. We show how the conservation of drug receptors between fungi and humans means that metabolites intended to inhibit competitor fungi often interact with human drug receptors, sometimes with unintended benefits. We also plot the distribution of drugs, antimicrobial compounds and psychoactive mushrooms onto a fungal tree and compare their distribution to those of all fungal metabolites. Finally, we examine the phenomenon of self-resistance and how this can be used to help predict metabolite mechanism of action and aid the drug discovery process.
An aromatic alkaloid-rich 'absolute' extract from Vepris gossweileri inhibited Saccharomyces cerevisiae at 62.5 μg.mL -1 and Bacillus subtilis at 500 μg.mL -1 . A loss of activity upon fractionation indicated possible synergistic effects. Three new acridones, gossweicridone A (3), B (4) and C (5) and known compounds from the extract were inactive. Combinations of compounds showed that a sub-fraction containing mixtures of minor compounds with (Ε)-caryophyllene augmented activity by 50-folds, with MIC values of 19.6 μg.mL -1 for S. cerevisiae and 375.0 μg.mL -1 for B. subtilis, demonstrating potent ΣFIC values of 0.02 and 0.375 respectively. From the active sub-fraction, three compounds were assigned as tecleanatalensine B, 13Shydroxy-9Z,11E,15E-octadecatrienoic acid and normelicopine. In combination with (Ε)-caryophyllene they separately demonstrated MIC values of 18 μg.mL -1 , 34 μg.mL -1 and 16 μg.mL -1 , respectively against S. cerevisiae. The synergistic combinations were more potent with addition of pheophytin A, suggesting that the synergistic antifungal effect of the extract is multi-layered.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
