Abstract
Covering: September 1964 to June 2023Bacteria and fungi living in symbiosis with insects have been studied over the last sixty years and found to be important sources of bioactive natural products. Not only classic producers of secondary metabolites such as Streptomyces and other members of the phylum Actinobacteria but also numerous bacteria from the phyla Proteobacteria and Firmicutes and an impressive array of fungi (usually pathogenic) serve as the source of a structurally diverse number of small molecules with important biological activities including antimicrobial, cytotoxic, antiparasitic and specific enzyme inhibitors. The insect niche is often the exclusive provider of microbes producing unique types of biologically active compounds such as gerumycins, pederin, dinactin, and formicamycins. However, numerous insects still have not been described taxonomically, and in most cases, the study of their microbiota is completely unexplored. In this review, we present a comprehensive survey of 553 natural products produced by microorganisms isolated from insects by collating and classifying all the data according to the type of compound (rather than the insect or microbial source). The analysis of the correlations among the metadata related to insects, microbial partners, and their produced compounds provides valuable insights into the intricate dynamics between insects and their symbionts as well as the impact of their metabolites on these relationships. Herein, we focus on the chemical structure, biosynthesis, and biological activities of the most relevant compounds.

Abstract
The marine sponge-derived fungus Stachylidium bicolor 293 K04 is a prolific producer of specialized metabolites, including certain cyclic tetrapeptides called endolides, which are characterized by the presence of the unusual amino acid N-methyl-3-(3-furyl)-alanine. This rare feature can be used as bait to detect new endolide-like analogs through customized fragment pattern searches of tandem mass spectrometry data using the Mass Spec Query Language (MassQL). Here, we integrate endolide-specific MassQL queries with molecular networking to obtain substructural information guiding the targeted isolation and structure elucidation of the new proline-containing endolides E (1) and F (2). We showed that endolide F (but not E) is a moderate antagonist of the arginine vasopressin V1A receptor, a member of the G protein-coupled receptor superfamily.

Abstract
Antimicrobial resistance is one of the main global threats to human health in the 21st century due to the rapid appearance of bacterial resistance and the lack of novel bioactive compounds. Natural products, especially from Actinomycetes, remain the best source to refill the drug industry pipeline. Different strategies have been pursued to increase the chances of discovering new molecules, such as studying underexplored environments like arthropod symbionts, which represent a relevant reservoir for active metabolites. This review summarizes recent research on the identification of bioactive molecules produced by Actinomycetes associated with arthropods' microbiome. The metabolites have been categorized based on their structural properties and host, highlighting that multidisciplinary approaches will be the key to fully understanding this complex relationship.

Abstract
Madurastatins are a group of pentapeptides containing an oxazoline moiety, and, in a few cases, an imidazolidinone ring as an additional structural feature. In our search for new potential antiparasitic metabolites from natural sources, we studied the acetone extracts from a culture of Actinomadura sp. CA-135719. The LC/HRMS analysis of this extract identified the presence of the known madurastatins C1 (1), D1 (4), and D2 (5) together with additional members of the family that were identified as the new madurastatins H2 (2) and 33-epi-D1 (3) after isolation and spectroscopic analysis. The planar structures of the new compounds were established by HRMS, ESI-qTOF-MS/MS, and 1D and 2D NMR data, and their absolute configuration was proposed using Marfey's and bioinformatic analyses of the biosynthetic gene cluster (BGC). A revision of the absolute configuration of madurastatins D1 and D2 is proposed. Additionally, madurastatins containing imidazolidinone rings are proved to be artifacts originating during acetone extraction of the bacterial cultures.

Abstract
The objective of this paper is to explore the function of the AOL-s00215g415 (Aog415) gene, which encodes for the synthesis of siderophore in the nematode trapping fungal model strain A. oligospora, in order to understand the relationship between siderophore biosynthesis and nematode trapping activity. After a through sequence analysis, it was determined that Aog415 is a siderophore-synthesizing NRPS. The product of this gene was then identified to be the hydroxamate siderophore desferriferrichrome, using mass spectrometry analysis. When compared to the WT strains, the Aog415 knockout strain exhibited a 60% decrease in siderophore content in fermentation broth. Additionally, the number of predatory rings of decreased by 23.21%, while the spore yield increased by 37.34%. The deletion of Aog415 did not affect the growth of A. oligospora in diverse nutrient medium. Lipid metabolism-related pathways were the primary targets of Aog415 disruption as revealed by the metabolomic analysis. In comparison to the WT, a significant reduction in the levels of glycerophospholipids, and glycolipids was observed in the mutation. The metabolic alteration in fatty acyls and amino acid-like molecules were significantly disrupted. The knockout of Aog415 impaired the biosynthesis of the hydroxamate siderophore desferriferrichrome, remodeled the flow of fatty acid in A. oligospora, and mainly reprogrammed the membrane lipid metabolism in cells. Desferriferrichrome, a hydroxamate siderophore affects the growth, metabolism and nematode trapping ability of A. oligospora by regulating iron intake and cell membrane homeostasis. Our study uncovered the significant contribution of siderophores to the growth and nematode trapping ability and constructed the relationship among siderophores biosynthesis, lipid metabolism and nematode trapping activity of A. oligospora, which provides a new insight for the development of nematode biocontrol agents based on nematode trapping fungi.

Abstract
Streptomyces spp. are well-known symbiotic microorganisms that produce antimicrobial metabolites against various pathogens. We isolated actinomycetes from the body surface of the termite Odontotermes formosanus and identified it as Streptomyces neopeptinius BYF101 based on 16S rRNA phylogenetic analysis. Chemical analysis of the cultures of termite-associated S. neopeptinius BYF101 via HR-MS2 and GNPS analyses enabled the isolation and identification of 20 metabolites, including the unreported obscurolide-type metabolites (1-3). The chemical structures of unreported compounds (1-3) were elucidated using HR-ESI-MS and 1D and 2D NMR analysis, and their absolute configurations were determined via chemical reactions followed by the application of competing enantioselective acylation (CEA) and computational methods for ECD and DP4+ probability calculation. The isolated compounds (1-20) were tested to determine their antifungal activity against two human fungal pathogens, Candida albicans and Cryptococcus neoformans. Among the compounds tested, indole-3-carboxylic acid (9) displayed antifungal activity against C. neoformans, with an MIC value of 12 μg/mL.

Abstract
Natural products (NPs) have historically played a primary role in the discovery of small-molecule drugs. However, due to the advent of other methodologies and the drawbacks of NPs, the pharmaceutical industry has largely declined in interest regarding the screening of new drugs from NPs since 2000. There are many technical bottlenecks to quickly obtaining new bioactive NPs on a large scale, which has made NP-based drug discovery very time-consuming, and the first thorny problem faced by researchers is how to dereplicate NPs from crude extracts. Remarkably, with the rapid development of omics, analytical instrumentation, and artificial intelligence technology, in 2012, an efficient approach, known as tandem mass spectrometry (MS/MS)-based molecular networking (MN) analysis, was developed to avoid the rediscovery of known compounds from the complex natural mixtures. Then, in the past decade, based on the classical MN (CLMN), feature-based MN (FBMN), ion identity MN (IIMN), building blocks-based molecular network (BBMN), substructure-based MN (MS2LDA), and bioactivity-based MN (BMN) methods have been presented. In this paper, we review the basic principles, general workflow, and application examples of the methods mentioned above, to further the research and applications of these methods.

Actinobacteria are involved into multilateral relationships between insects, their food sources, infectious agents, etc. Antibiotics and related natural products play an essential role in such systems. The literature from the January 2016-August 2022 period devoted to insect-associated actinomycetes with antagonistic and/or enzyme-inhibiting activity was selected. Recent progress in multidisciplinary studies of insect-actinobacterial interactions mediated by antibiotics is summarized and discussed.

Abstract
Natural products containing the highly unusual phosphotriester ring are known to be potent serine hydrolase inhibitors. The long-chain bicyclic enol-phosphotriester salinipostins (SPTs) from the marine actinomycete Salinispora have been identified as selective antimalarial agents. A potential regulatory function has been suggested for phosphotriesters based on their structural relationship with actinomycete signaling molecules and the prevalence of spt-like biosynthetic gene clusters across actinomycetes. In this study, we established a mass spectrometry-guided screening method for phosphotriesters focusing on their characteristic fragment ions. Applying this screening method to the SPT producer Salinispora tropica CNB-440, new SPT analogues (4-6) were discovered and their structures were elucidated by spectroscopic analyses. Previously known and herein-identified SPT analogues inhibited the activity of human monoacylglycerol lipase (MAGL), a key serine hydrolase in the endocannabinoid system, in the nanomolar range. Our method could be applied to the screening of phosphotriesters, potential serine hydrolase inhibitors and signaling molecules.
