Abstract
Fluorescent probes have gained profound use in biotechnology, drug discovery, medical diagnostics, molecular and cell biology. The development of methods for the translation of fluorophores into fluorescent probes continues to be a robust field for medicinal chemists and chemical biologists, alike. Access to new experimental designs has enabled molecular diversification and led to the identification of new approaches to probe discovery. This review provides a synopsis of the recent lessons in modern fluorescent probe discovery.

Abstract
The design of synthetic routes by retrosynthetic logic is decisively influenced by the transformations available. Transition-metal-catalyzed C-H activation has emerged as a powerful strategy for C-C bond formation, with myriad methods developed for diverse substrates and coupling partners. However, its uptake in total synthesis has been tepid, partially due to their apparent synthetic intractability, as well as a lack of comprehensive guidelines for implementation. This Review addresses these issues and offers a guide to identify retrosynthetic opportunities to generate C-C bonds by C-H activation processes. By comparing total syntheses accomplished using traditional approaches and recent C-H activation methods, this Review demonstrates how C-H activation enabled C-C bond construction has led to more efficient retrosynthetic strategies, as well as the execution of previously unattainable tactical maneuvers. Finally, shortcomings of existing processes are highlighted; this Review illustrates how some highlighted total syntheses can be further economized by adopting next-generation ligand-enabled approaches.

Abstract
Fluorescent natural products are a rich source of drugs and chemical probes, but their innate fluorescence can interfere with fluorescence-based screening assays. Caspase-8 is a key player in apoptosis, its inhibition having been found to be beneficial for treatment of inflammatory and neurodegenerative diseases. Small-molecular inhibitors of caspase-8 remain sparsely reported, however. In this study, we firstly developed a light-up probe based on an AIEgen and capable of targeting caspase-8. This fluorescent dye has a Stokes shift of 200 nm, which could allow the innate fluorescence signals of natural products to be avoided. On screening a library of 86 fluorescent natural products, we found for the first time that gossypol showed potent inhibition of caspase-8 in vitro and in situ. This unique light-up probe, coupled with colored natural products, could represent an efficient approach to hit discovery for druggable targets.

Abstract
The development of efficient syntheses of complex natural products has long been a major challenge in synthetic chemistry. Designing cascade reactions and employing bioinspired transformations are an important and reliable means of achieving this goal. Presented here is a combination of these two strategies, which allow efficient asymmetric synthesis of the cinchona alkaloid (+)-cinchonidine. The key steps of this synthesis are a controllable, visible-light-induced photoredox radical cascade reaction to efficiently access the tetracyclic monoterpenoid indole alkaloid core, as well as a practical biomimetic cascade rearrangement for the indole to quinoline transformation. The use of stereoselective chemical transformations in this work makes it an efficient synthesis of (+)-cinchonidine.

Abstract
We report a novel approach to the classical natural product quinine that is based on two stereoselective key steps, namely a C-H activation and an aldol reaction, to unite the two heterocyclic moieties of the target molecule. This straightforward and flexible strategy enables a concise synthesis of natural (-)-quinine, the first synthesis of unnatural (+)-quinine, and also provides access to unprecedented C3-aryl analogues, which were prepared in only six steps. We additionally demonstrate that these structural analogues exhibit improved antimalarial activity compared with (-)-quinine both in vitro and in mice infected with Plasmodium berghei.

Abstract
Mauveine, a chemical icon, is no longer commercially available. If nowadays one wanted to have a sample of the original Perkin, or Caro, mauveine, and see its colour, where would one find it? The answer is on UK Victorian 6d postage stamps from 1867-1880. This was found from a comparison with historical samples of mauveine, from both William Perkin and a Heinrich Caro sample (here analysed for the first time). These have distinctly different compositions and this was used to identify the origin of mauveine in the postage stamps, with evidence found for mauveine made by both Perkin's and Caro's synthesis.

Abstract
Proteasome inhibitors are rapidly evolving as potent treatment options in cancer therapy. One of the most promising drug candidates of this type is salinosporamide A from the bacterium Salinispora tropica. This marine natural product possesses a complex, densely functionalized γ-lactam-β-lactone pharmacophore, which is responsible for its irreversible binding to its target, the β subunit of the 20S proteasome. Salinosporamide A entered phase I clinical trials for the treatment of multiple myeloma only three years after its discovery. The strong biological activity and the challenging structure of this compound have fueled intense academic and industrial research in recent years, which has led to the development of more than ten syntheses, the elucidation of its biosynthetic pathway, and the generation of promising structure-activity relationships and oncological data. Salinosporamide A thus serves as an intriguing example of the successful interplay of modern drug discovery and biomedical research, medicinal chemistry and pharmacology, natural product synthesis and analysis, as well as biosynthesis and bioengineering.

Abstract
Small but effective: two natural-product-like inhibitors of tumor necrosis factor α (TNF-α; represented in green in the picture) have been identified using structure-based virtual screening. These compounds represent only the third and fourth examples of direct targeting of TNF-α by a small molecule, and display potency comparable to that of the strongest TNF-α inhibitor reported to date.

Abstract
In 1918, Paul Rabe and Karl Kindler reported the three-step conversion of d-quinotoxine into quinine. In 1944 Robert B. Woodward and William von Eggers Doering reported the total synthesis of homomeroquinene and d-quinotoxine from 7-hydroxyisoquinoline. Based on the transformations by Rabe and Kindler, Woodward and Doering asserted the "Total Synthesis of Quinine" (the title of their 1944 and 1945 papers). In 2000 and 2001, Gilbert Stork concluded that the claim by Woodward and Doering is a "myth" because they had synthesized only homomeroquinene and d-quinotoxine; no synthetic quinine had been made in Cambridge. In fact, Rabe and Kindler never published the experimental details of their conversion of d-quinotoxine into quinine. This Review presents the results of a detailed examination of the synthesis of cinchona alkaloids, and previously unpublished material combined with unpublished material and numerous interviews give insight into the lives of the personalities in this nearly 100-year saga.
