Many terpene glycosides exhibit contrasteric patterns of 1,2-diol glycosylation in which the more hindered alcohol bears a sugar; protection less only increases steric repulsion. Here, we report method for using new sugar-linker that forms cleavable, 10-membered ring with high efficiency, leading to syntheses cotylenin E, J, and ISIR-050. Linker selection was aided by DFT calculations side reactions stereoselectivity, as well conformational analyses autoDFT, Python script converts SMILES strings DFT-optimized ensembles.

Natural products are the result of Nature's exploration biologically relevant chemical space through evolution and an invaluable source bioactive small molecules for biology medicinal chemistry. Novel concepts discovery new compound classes based on natural product structure may enable wider space. The pseudo-natural concept merges relevance with efficient by means fragment-based development to inspire matter de novo combination fragments in unprecedented arrangements. novel scaffolds retain biological but not obtainable known biosynthetic pathways which can lead chemotypes that have unexpected or bioactivities. Herein, we cover workflow design development, highlight recent examples, discuss a cheminformatic analysis significant portion active synthetic compounds were found be products. We compare as human-made equivalent, i.e. structure.

Pseudo-natural products (PNPs) combine natural product (NP) fragments in novel arrangements not accessible by current biosynthesis pathways. As such they can be regarded as non-biogenic fusions of NP-derived fragments. They inherit key biological characteristics the guiding product, chemical and physiological properties, yet define small molecule chemotypes with unprecedented or unexpected bioactivity. We iterate design principles underpinning PNP scaffolds highlight their syntheses investigations. provide a cheminformatic analysis collections assessing molecular properties shape diversity. propose discuss how iterative NP structure, design, synthesis, evaluation PNPs human-driven branch evolution products, that is, structure.

Chirality is an inherent aspect of biology, and interactions between biomolecules are often influenced by stereochemistry topographic complexity. This has implications for how small-molecule libraries assembled screening campaigns in chemical biology drug discovery. Here we review the state field context harnessing chirality as a source information at chemistry-biology interface. We further highlight emergence containing stereoisomeric sets compounds concept using stereoselectivity phenotype and/or target engagement way to prioritize actionable targets streamline identification selective potent modulators disease-relevant biomolecules. The density FDA-approved drugs effect on molecular complexity reported. Finally, axial atroposelectivity discussed potential expansions aforementioned concepts.

The fraction of sp3-hybridized carbons (Fsp3) and the stereogenic (FCstereo) are two widely employed scores molecular complexity with strong links to biologically relevant features. However, they do not comprehensively express topology, often match chemical intuition complexity. We propose spacial score (SPS) as an empirical scoring system that builds upon principle underlying Fsp3 FCstereo expresses a compound in uniform manner on highly granular scale. size-normalized SPS (nSPS) can differentiate distributions natural products synthetic compounds is applicable analysis biological activity data. Analysis ChEMBL database revealed general trends increasing selectivity potency nSPS. also be used advantageously planning synthesis programs for direct comparison transformations intermediates reaction sequences.

Although alkynes are one of the smallest functional groups, they among most versatile building blocks for organic chemistry, with applications ranging from biochemistry to material sciences. Alkynylation reactions have traditionally relied on use acetylenes as nucleophiles. The discovery and development ethynyl hypervalent iodine reagents allowed greatly expand transfer electrophilic synthons. In this feature article progress in field since 2018 will be presented. After a short introduction alkynylation reagents, developments synthesis alkynyl discussed. Their recent base-mediated transition-metal catalyzed alkynylations described.

Plants fungi, particular, supplied materials that altered behavior, perception, well-being profoundly. Many active principles remain well-known today: strychnine, morphine, psilocybin, ephedrine. The potential to circumvent constraints supply explore properties these led field product synthesis. This research delivered new molecules with properties, but also fundamental insights chemistry nonmetal elements H, C, N, O, P, S, Se, their combinations, i.e., organic chemistry.
