Abstract
The prognosis with pancreatic cancer is among the poorest of any human cancer. One of the important factors is the tumor hypoxia. Targeting tumor hypoxia is considered a desirable therapeutic option. However, it has not been translated into clinical success in the treatment of pancreatic cancer. With enhanced cytotoxicities against hypoxic pancreatic cancer cells, BE-43547A2 (BE) may serve as a promising template for hypoxia target strategy. Here, based on rational modification, a BE prodrug (NMP-BE) is encapsulated into sulfonated azocalix[5]arene (SAC5A) to generate a supramolecular dual hypoxia-responsive complex NMP-BE@SAC5A. Benefited from the selective load release within cancer cells, NMP-BE@SAC5A markedly suppresses tumor growth at low dose in pancreatic cancer cells xenograft murine model without developing systemic toxicity. This research presents a strategy for the modification of covalent compounds to achieve efficient delivery within tumors, a horizon for the realization of safe and reinforced hypoxia target therapy using a simple approach.

Abstract
Eukaryotic elongation factor 1A (eEF1A) canonically delivers amino acyl tRNA to the ribosomal A site during the elongation stage of protein biosynthesis. Yet paradoxically, the oncogenic nature of this instrumental protein has long been recognized. Consistently, eEF1A has proven to be targeted by a wide assortment of small molecules with excellent anticancer activity, among which plitidepsin has been granted approval for the treatment of multiple myeloma. Meanwhile, metarrestin is currently under clinical development for metastatic cancers. Bearing these exciting advances in mind, it would be desirable to present a systematic up-to-date account of the title topic, which, to the best of our knowledge, has thus far been unavailable in the literature. The present review summarizes recent advances in eEF1A-targeting anticancer agents, both naturally occurring and synthetically crafted, with regard to their discovery or design, target identification, structure–activity relationship, and mode of action. Their structural diversity and differential eEF1A-targeting mechanisms warrant continuing research in pursuit of curing eEF1A-driven malignancy.

Abstract
Enamine and enol ethers are nucleophilic functional groups that are well known to most chemists. When enamine or enol ethers are present in natural products, they are nearly exclusively found as derivatives having a direct connection to electron-withdrawing groups for stabilization, and the resulting larger entities, such as enamides or enol acylates, can be further extended or modified in the framework of natural products. The restricted conformational space that is associated with even simple enamine and enol ether derivatives can be a strong determinant of the overall molecular structure, and the more polarized derivatives can endow some natural products with electrophilic properties and thus facilitate covalent interactions with biological targets.In this Account, I describe our efforts (published since 2016) to prepare natural products from several different classes that all feature enamine or enol ether derivatives as key functionalities. Our choice of targets has been guided by a desire to illuminate unknown biological mechanisms associated with the compounds or, alternatively, to improve upon known biological activities that appear to be promising from a biomedical perspective. In the present text, however, the exclusive focus will be on the syntheses.First, I will discuss the basic properties of the functional groups and briefly present a small collection of illustrative and inspirational examples from the literature for their construction in different complex settings. Next, I will provide an overview of our work on the macrocyclic APD-CLD natural products, rakicidin A and BE-43547A1, involving the development of an efficient macrocyclization strategy and the development of methods to construct the hallmark APD group: a modified enamide. The synthesis of the meroterpenoid strongylophorine-26 is discussed next, where we developed an oxidative quinone methoxylation to build a vinylogous ester group in the final step of the synthesis and employed FeCl3-mediated cascade reactions for the rapid assembly of the overall scaffold to enable a short semisynthesis from isocupressic acid. An efficient core scaffold assembly was also in focus in our synthesis of the alkaloid streptazone A with the signature enaminone system being assembled through a rhodium-catalyzed Pauson-Khand reaction. Sequential, site-selective redox manipulations were developed to arrive at strepatzone A and additional members of the natural product family. Finally, I discuss our work to prepare analogs of complex polyether ionophores featuring functionalized tetronic acids as cation-binding groups. A method for the construction of a suitably protected chloromethylidene-modified tetronate is presented which enabled its installation in the full structure through a C-acylation reaction. This work exemplifies how components of abundant polyether ionophores can be recycled and used to access new structures which may possess enhanced biological activities.

Abstract
Pancreatic ductal adenocarcinoma (PDAC) is a highly aggressive malignant tumor and resistant to most therapies. Pancreatic cancer stem cells (PCSCs) had critical role in regulating PDAC progression, metastasis, and drug resistance. Therefore, targeting PCSCs is considered to be a promising strategy for treatment of PDAC. However, there is no effective drug that can selectively ablate PCSCs. A series of twenty rakicidin A analogues were synthesized via a combinatorial strategy and evaluated for their anti-PDAC activities, and the structure-activity relationship was also discussed. Compound 32g was prepared in 14 linear steps with 5.05% overall yield, which is much more efficient than our previously reported total synthesis of rakicidin A (19 linear steps with 0.19% yield). In a highly metastatic pancreatic cancer cell line ASPC-1, compound 32g showed about 4 times higher potency (IC50 = 0.022 μM) than rakicidin A (IC50 = 0.082 μM) at hypoxia condition, and 12 folds of hypoxia selectivity (IC50 = 0.27 μM at nomoxia condition). In contrast, the activity of adriamycin in the same hypoxic condition decreased. The percentage of PCSCs (with CD24+CD44+ESA+ biomarker), activity of ALDH, and the number of tumorspheres in PANC-1 cells were greatly reduced after treatment of 32g. More importantly, the tumor-initiating frequency was reduced by 19 folds after the treatment of 32g, which is better than that of rakicidin A (reduction of 4.7 folds).

Abstract
Absolute configurations of the three consecutive chiral centers in the cyclic depsipeptide microtermolide A have been tentatively assigned as 2‴R, 3‴R, and 4‴R. However, on the basis of a structural comparison with vinylamycin, another depsipeptide with a unique 4-amino-2,4-pentadienolate structure, the chiral centers could also be assigned as 2‴R, 3‴R, and 4‴S. Here, the first total synthesis of microtermolide A is reported and the configurations of the three consecutive chiral centers were confirmed to be 2‴R, 3‴R, and 4‴S. A similar approach was used to determine the analogous centers in microtermolide B as 2‴R, 3‴R, and 4‴S.

Abstract
Marine microorganisms possess unique metabolic and physiological features and are an important source of new biomolecules, such as biosurfactants. Some of these surface-active compounds synthesized by marine microorganisms exhibit antimicrobial, anti-adhesive and anti-biofilm activity against a broad spectrum of human pathogens (including multi-drug resistant pathogens), and could be used instead of existing drugs to treat infections caused by them. In other cases, these biosurfactants show anti-cancer activity, which could be envisaged as an alternative to conventional therapies. However, marine biosurfactants have not been widely explored, mainly due to the difficulties associated with the isolation and growth of their producing microorganisms. Culture-independent techniques (metagenomics) constitute a promising approach to study the genetic resources of otherwise inaccessible marine microorganisms without the requirement of culturing them, and can contribute to the discovery of novel biosurfactants with significant biological activities. This paper reviews the most relevant biosurfactants produced by marine microorganisms with potential therapeutic applications and discusses future perspectives and opportunities to discover novel molecules from marine environments.

Abstract
Developing new classes of anticancer molecules has always been a major scientific challenge owing to multidrug resistance of cancer cells to conventional chemotherapeutic agents. Microbial amphiphiles, particularly lipopeptides and glycolipids, have recently emerged as potential new-generation anticancer agents, owing to low toxicity, high efficacy and easy biodegradability. They exhibit anticancer activities by retarding cell cycle progression, inhibiting crucial signaling pathways such as Akt, extracellular signal-regulated kinase/c-Jun N-terminal kinase (ERK/JNK) and Janus kinase/signal transducer and activator of transcription (JAK/STAT), reducing angiogenesis, activating natural killer T (NKT) cells and inducing apoptosis through death receptors in cancer cells. It has been well established that the oncogenic signals of cancer cells are amplified by the overexpression of various membrane-bound receptors such as epidermal growth factor receptor (EGFR), vascular endothelial growth factor receptor (VEGFR), platelet-derived growth factor receptor (PDGFR) and insulin-like growth factor receptor (IGFR). Microbial amphiphiles, upon interaction with the cell membrane, are believed to suppress the activities of these cell surface receptors by fatty acid chain mediated membrane destabilization. This review analyzes the modes and mechanisms of action of these green molecules for application as potential anticancer agents.
