Abstract
Mellpaladines A-C (1-3) and dopargimine (4) are dopamine-derived guanidine alkaloids isolated from a specimen of Palauan Didemnidae tunicate as possible modulators of neuronal receptors. In this study, we isolated the dopargimine derivative 1-carboxydopargimine (5), three additional mellpaladines D-F (6-8), and serotodopalgimine (9), along with a dimer of serotonin, 5,5'-dihydroxy-4,4'-bistryptamine (10). The structures of these compounds were determined based on spectrometric and spectroscopic analyses. Compound 4 and its congeners dopargine (11), nordopargimine (15), and 2-(6,7-dimethoxy-3,4-dihydroisoquinolin-1-yl)ethan-1-amine (16) were synthetically prepared for biological evaluations. The biological activities of all isolated compounds were evaluated in comparison with those of 1-4 using a mouse behavioral assay upon intracerebroventricular injection, revealing key functional groups in the dopargimines and mellpaladines for in vivo behavioral toxicity. Interestingly, these alkaloids also emerged during a screen of our marine natural product library aimed at identifying antiviral activities against dengue virus, SARS-CoV-2, and vesicular stomatitis Indiana virus (VSV) pseudotyped with Ebola virus glycoprotein (VSV-ZGP).

Abstract
In the development of applications to mitigate nuisance cyanobacterial blooms, environmentally friendly approaches have gained much attention. Recently, we found a bacterial strain Go58, which was isolated from the biofilm of a water plant, that showed potent algicidal activity against the bloom-forming cyanobacterium Microcystis aeruginosa. Whole genome sequencing of strain Go58 suggested that it is potentially a novel species closely related to Pseudomonas protegens. Pyoluteorins were obtained from the culture broth of this strain, and they demonstrated high toxicity against cultured cyanobacterial species, including M. aeruginosa and Anabaena cylindrica, but less toxicity against eukaryotic microalgae and other aquatic organisms. The production of pyoluteorin was enhanced by the presence of the target cyanobacterium. When a wild-caught microalgal consortium was treated with either strain Go58 or pyoluteorin, both efficiently suppressed the growth of harmful wild cyanobacteria, but promoted the growth of some specific eukaryotic microalgae. Since P. protegens is globally ubiquitous and highly anticipated to be a biopesticide for infectious diseases in the field of agriculture, the similar bacterial group identified in this study may also have potential as a safe on-site collectable biological countermeasure for controlling cyanobacterial blooms.

Abstract
Fourteen aromatic metabolites (6-19) were isolated from an aqueous extract of the solitary tunicate Cnemidocarpa irene collected in Hokkaido, Japan. The structures of the metabolites were determined based on the spectroscopic interpretations, including one- and two-dimensional NMR, mass spectra, UV, and circular dichroism data. The biopterin analogue 10 modulated the behavior of mice after intracerebroventricular injection and showed a weak affinity to ionotropic glutamate receptor subtypes. Analyses of fluorescent coelomic fluid of the tunicate revealed that pterin 12 was responsible for the fluorescence of the blood cells, while β-carbolines 1 and 3 were fluorescent compounds in the serum. The metabolic profiles in adults, juveniles, larvae, and eggs of the animal differed substantially, suggesting that the metabolism of the animal, especially biosynthesis of aromatic secondary metabolites, changes over different life stages.

Abstract
Questiomycin A (1) along with three new compounds, questiomycins C–E (2–4), were isolated from culture of Alteromonas sp. D, an algicidal marine bacterium, guided by algal lethality assay using the raphidophyte, Chattonella antiqua, one of the causative organisms of harmful algal bloom. The structures of 1–4 were assigned on the basis of their spectrometric and spectroscopic data. Compounds 1 to 4 exhibited algicidal activity against C. antiqua with LC50 values ranging from 0.18 to 6.37 μM. Co-cultivation experiment revealed that 1 was produced only when the microalgae and the bacterium are in close contact, suggesting that some interactions between them trigger the biosynthesis of questiomycins. These results suggested that the algicidal bacteria such as Alteromonas sp. D can control microalgae chemically in marine ecosystem.

Abstract
New brominated β-carbolines irenecarbolines A (1) and B (4) along with known β-carbolines 2 and 3 and a new 8-oxoisoguanine derivative, 5, were isolated from a solitary ascidian, Cnemidocarpa irene. The structures of these compounds were determined on the basis of their spectral data. All, except for 3, inhibited the action of acetylcholinesterase (AchE). The activities of 1 and 5 were comparable to those of galantamine, a clinically used AchE inhibitor. Compounds 1 and 2 were found to be present in high concentrations in blood, and fluorescence was observed in certain types of cells found in the blood of the tunicate.

Abstract
A new polyamine-modified indole derivative protoaculeine B (1) was isolated from Okinawan marine sponge Axinyssa aculeata. The structure of 1 was assigned on the basis of spectral data along with chemical transformations. Because the structure of 1 greatly inferred the N-terminal amino acid for highly modified peptide toxin aculeines, the probable structure for aculeine B was proposed on the basis of high-resolution mass spectral analysis.

Abstract
A siderophore, named bisucaberin B, was isolated from Tenacibaculum mesophilum bacteria separated from a marine sponge collected in the Republic of Palau. Using spectroscopic and chemical methods, the structure of bisucaberin B (1) was clearly determined to be a linear dimeric hydroxamate class siderophore. Although compound 1 is an open form of the known macrocyclic dimer bisucaberin (2), and was previously described as a bacterial degradation product of desferrioxamine B (4), the present report is the first description of the de novo biosynthesis of 1. To the best of our knowledge, compound 1 is the first chemically characterized siderophore isolated from a bacterium belonging to the phylum Bacteroidetes.

Abstract
A siderophore biosynthetic gene cluster was cloned from a metagenomic library generated from deep sea sediment. The gene cluster was successfully expressed in Escherichia coli to produce bisucaberin, a siderophore originally reported from the marine bacterium Alteromonas haloplanktis. The cloned bisucaberin biosynthetic gene cluster was moderately similar to that of the known bisucaberin producer Vibrio salmonicida. However, the cloned gene cluster consists of four genes rather than three genes found in the V. salmonicida cluster. The low overall homology of the amino acid and nucleotide sequences with those of other species suggests that the cloned genes were derived from one of the unsequenced bacteria including uncultured species.
