Book Description
The first contribution describes apolar and polar molecular fossils and, in particular biomarkers, along the lines usually followed in organic chemistry textbooks, and points to their bioprecursors when available. Thus, the apolar compounds are divided in linear and branched alkanes followed by alicyclic compounds and aromatic and heterocyclic molecules, and, in particular, the geoporphyrins. The polar molecular fossils contain as functional groups or constituent units ethers, alcohols, phenols, carbonyl groups, flavonoids, quinones, and acids, or are polymers like kerogen, amber, melanin, proteins, or nucleic acids. The final sections discuss the methodology used and the fundamental processes encountered by the biomolecules described, including diagenesis, catagenesis, and metagenesis. The second contribution covers the distribution of phthalides in nature and the findings in the structural diversity, chemical reactivity, biotransformations, syntheses, and bioactivity of natural and semisynthetic phthalides.

Book Description
The three reviews cover the advances in the chemistry and biology of withanolides over the last 16 years, review the chemistry and biology of the rocaglamide-type derivatives and related compounds, with emphasis on their structural diversity, biosynthesis, pharmacological significance and total synthesis, and summarize the extensive chemistry and biology studies on a natural product, which have resulted in a novel therapy approved worldwide.

Book Description
This volume presents three chapters discussing a range of topics. Chapter 1 deals with the development of efficient methods for compound dereplication that have been critical in the re-emergence of research on natural products as a source of new drug leads. It describes the main methods of dereplication, which rely on the combined use of large natural product databases and spectral libraries, alongside the information obtained from chromatographic, UV-Vis, MS, and NMR spectroscopic analyses of the samples of interest. Chapter 2 describes 989 plant natural products and their ecological functions in plant-herbivore, plant-microorganism, and plant-plant interactions. These compounds include alkaloids, phenols, terpenoids, and other structural types. The information presented should provide the basis for in-depth research on these plant natural products and their natural functions, and also for their further development and utilization. Chapter 3 focuses on lichens, with each constituting a symbiotic association composed of a primary mycobiont and one or more photobionts living mutualistically. Covered are lichens and their bionts, taxonomic identification, and their chemical constituents as exemplified by what is found in lichen biomes, especially those endemic to North America. Extraction and isolation procedures, as well as updates on dereplication methods using mass spectrometric GNPS and NMR spectroscopic spin network fingerprint procedures, and marker-based techniques to identify lichens are discussed. The isolation and structure elucidation of secondary metabolites of an endolichenic Penicillium species that produces bioactive compounds is described in detail.
