Naturally Occurring

Cyanogenic glycosides are an important and widespread class of plant natural products, which are however structurally less diverse than many other classes of natural products. So far, 112 naturally occurring cyanogenic glycosides have been described in the phytochemical literature. Currently, these unique compounds have been reported from more than 2500 plant species. Natural cyanogenic glycosides show variations regarding both the aglycone and the sugar part of the molecules. The predominant sugar moiety is glucose but many substitution patterns of this glucose moiety exist in nature. Regarding the aglycone moiety, four different basic classes can be distinguished, aliphatic, cyclic, aromatic, and heterocyclic aglycones. Our overview covers all cyanogenic glycosides isolated from plants and includes 33 compounds with a non-cyclic aglycone, 20 cyclopentane derivatives, 55 natural products with an aromatic aglycone, and four dihydropyridone derivatives. In the following sections, we will provide an overview about the chemical diversity known so far and mention the first source from which the respective compounds had been isolated. This review will serve as a first reference for researchers trying to find new cyanogenic glycosides and highlights some gaps in the knowledge about the exact structures of already described compounds.

Marine invertebrates have been reported to be an excellent resource of many novel bioactive compounds. Studies reported that Indonesia has remarkable yet underexplored marine natural products, with a high chemical diversity and a broad spectrum of biological activities. This review discusses recent updates on the exploration of marine natural products from Indonesian marine invertebrates (i.e., sponges, tunicates, and soft corals) throughout 2007–2020. This paper summarizes the structural diversity and biological function of the bioactive compounds isolated from Indonesian marine invertebrates as antimicrobial, antifungal, anticancer, and antiviral, while also presenting the opportunity for further investigation of novel compounds derived from Indonesian marine invertebrates.

Human Disorders

Background: Natural products and their derived phytochemicals have been used in the medicine and gaining importance in the modern medicine due to their therapeutic potential and health beneficial effect on human disorders. Plenty of herbal drug based products are available in the market and playing an important role in the human health care system due to their health beneficial properties in human being. In the modern age we can find many herbal based products in the market mainly prepared from the natural products and used for the prevention and treatment of various human disorders. Benzylisoquinoline alkaloids are the important class of alkaloidal compounds and the better example are morphine, codeine, sanguinarine, berberine and canadine which are mainly known for their medicinal value in the medicine. Methods: Hydrastis canadensis is the important medicinal plant found to contain a significant amount of canadine, hydrastine and berberine. In the present investigation, numerous scientific databases such as Google, Pubmed, Science direct etc. have been searched to collect the important scientific information of canadine and analyzed to know the health beneficial aspect of canadine in the medicine. All the collected scientific information data’s were analyzed and have been categorized into mainly pharmacological and analytical aspects. Results: From the analysis of the collected scientific information, it was found that Hydrastis canadensis contain significant amount of canadine with many more phytochemical including canadaline, hydrastidine, isohydrastidine etc. Pharmacological activity data analysis revealed the biological importance of Hydrastis canadensis in the medicine for their traditional uses against gastritis, colitis, duodenal ulcers, loss of appetite, liver disease, bile secretion disorder, snake bites and vaginitis in the medicine. However, scientific data analysis of canadine revealed their effectiveness for their acetylcholinesterase inhibitory activity, anti-cancer, anti-microbial, anti-allergic activity and anti-oxidant activity. Different modern analytical tools have been used in the modern medicine for the isolation and quantification of canadine in the Hydrastis canadensis. Conclusion: Present investigation revealed the medicinal importance and pharmacological activities of a canadine in the medicine for the treatment of numerous human health complications. These scientific data will be helpful to the scientist to know the biological importance of canadine in the medicine against various forms of human complications.

Background: Food chemicals are a cornerstone in the food industry. However, its chemical diversity has been explored on a limited basis, for instance, previous analysis of food-related databases were done up to 2,200 molecules. The goal of this work was to quantify the chemical diversity of chemical compounds stored in FooDB, a database with nearly 24,000 food chemicals. Methods: The visual representation of the chemical space of FooDB was done with ChemMaps, a novel approach based on the concept of chemical satellites. The large food chemical database was profiled based on physicochemical properties, molecular complexity and scaffold content. The global diversity of FooDB was characterized using Consensus Diversity Plots. Results: It was found that compounds in FooDB are very diverse in terms of properties and structure, with a large structural complexity. It was also found that one third of the food chemicals are acyclic molecules and ring-containing molecules are mostly monocyclic, with several scaffolds common to natural products in other databases. Conclusions: To the best of our knowledge, this is the first analysis of the chemical diversity and complexity of FooDB. This study represents a step further to the emerging field of “Food Informatics”. Future study should compare directly the chemical structures of the molecules in FooDB with other compound databases, for instance, drug-like databases and natural products collections. An additional future direction of this work is to use the list of 3,228 polyphenolic compounds identified in this work to enhance the on-going polyphenol-protein interactome studies.

Pharmaceutical Activity

Natural products from plants are still important sources for the development of drugs, despite their recent neglect in pharmaceutical discovery programmes. The rapidly dwindling number of species endangers the availability of these natural compounds, which are characterized by the immense chemical and functional diversity ultimately responsible for their pharmaceutical activity. Although many steps in the drug discovery process have been continuously modified during recent years, a common dilemma is still unresolved, i.e. the supply crisis for hits discovered in rare wild plants due to their inaccessibility or lack of reproducibility. New technology, combining tissue culture, functional genomics and metabolomics, shows promise to overcome these problems and even to supply a greater chemical diversity of compounds.

Microbial Biosynthesis

Microbial cell factories are extensively used for the biosynthesis of value-added chemicals, biopharmaceuticals, and biofuels. Microbial biosynthesis is also realistic for the production of heterologous molecules including complex natural products of plant and microbial origin. Glycosylation is a well-known post-modification method to engineer sugar-functionalized natural products. It is of particular interest to chemical biologists to increase chemical diversity of molecules. Employing the state-of-the-art systems and synthetic biology tools, a range of small to complex glycosylated natural products have been produced from microbes using a simple and sustainable fermentation approach. In this context, this review covers recent notable metabolic engineering approaches used for the biosynthesis of glycosylated plant and microbial polyketides in different microorganisms. This review article is broadly divided into two major parts. The first part is focused on the biosynthesis of glycosylated plant polyketides in prokaryotes and yeast cells, while the second part is focused on the generation of glycosylated microbial polyketides in actinomycetes.
