Moore JE, Millar BC. Lack of correlation between surface water area and infection with Pseudomonas aeruginosa and the non-tuberculous mycobacteria (NTMs) in patients with cystic fibrosis (CF). INFECTIOUS MEDICINE 2024; 3:100125. [PMID: 39314805 PMCID: PMC11417682 DOI: 10.1016/j.imj.2024.100125] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/06/2024] [Revised: 05/07/2024] [Accepted: 08/01/2024] [Indexed: 09/25/2024]
Abstract
Background People with cystic fibrosis (CF) may develop clinically significant chronic respiratory infections with Pseudomonas aeruginosa (PA) and non-tuberculous mycobacteria (NTM). Open water has been suggested to be an important source for continuous or intermittent exposure to these pathogens. To date, there has been a paucity of studies examining the relationship between chronic PA and NTM infection in CF patients and surfaces waters, including blue spaces. The aim of this study was therefore to examine the relationship between chronic pulmonary infection with PA and NTMs in children and adults with CF in European countries and area of surface waters, including blue spaces. Methods European CF registry data detailing incidence of chronic PA and NTM infection in adults and children with CF in Europe (n=41,486 in 24 European countries) was correlated with surface water area data from the same countries (approx. 678,278 km2) employing Spearman coefficients. Results Correlation of chronic PA infection in children and adults and surface water area were not significant (p=0.0680 and p=0.8448, respectively), as was NTM infection (p=0.7371 and p=0.0712, respectively). Conclusions Acquistion of PA and its avoidance in people with CF is a complicated dynamic, not solely driven by close association with surface water, but through the integration of several other factors, including mitigations by people with CF to avoid high risk scenarios with surface water. This study was unable to demonstrate a correlation between PA and NTM infection in people with cystic fibrosis and surface water area at a national level. CF patients should continue to be vigilant about potential infection risks posed by water and take evidence-based decisions regarding their behaviour around water to protect them for acquiring these organisms from these sources.

Abstract
Marine-derived piperazine alkaloids (MDPAs) constitute a significant group of natural compounds known for their diverse structures and biological activities. Over the past five decades, substantial efforts have been devoted to isolating these alkaloids from marine sources and characterizing their chemical and bioactive profiles. To date, a total of 922 marine-derived piperazine alkaloids have been reported from various marine organisms. These compounds demonstrate a wide range of pharmacological properties, including cytotoxicity, antibacterial, antifungal, antiviral, and various other activities. Notably, among these activities, cytotoxicity emerges as the most prominent characteristic of marine-derived piperazine alkaloids. This review also summarizes the structure-activity relationship (SAR) studies associated with the cytotoxicity of these compounds. In summary, our objective is to provide an overview of the research progress concerning marine-derived piperazine alkaloids, with the aim of fostering their continued development and utilization.

Abstract
Ten diphenyl ethers (DPEs), including nine undescribed analogs named betaethrins A-I, were isolated from the desert plant endophytic fungus Phoma betae A.B. Frank (Didymellaceae). Their structures were determined mainly by NMR, HR-ESI-MS spectral and X-ray diffraction experiments. Betaethrins D-I possessed different fatty acid chains connected with the B-ring, which was the first report in all DPEs. The shielding effect of the B-ring on H-6 (A-ring) in methyl barceloneate, betaethrin A and betaethrins D-F (asterric acid analogs) was first observed and analyzed, which could differentiate the 1H-NMR chemical shift values of H-4/H-6 without the assistance of 3-OH. An empirical rule was then suggested: the steric hindrance between the A- and B-rings in asterric acid analogs might prevent these two aromatic rings from rotating freely, which led to the 1H-NMR chemical shift value of H-6 being in the high field zone due to the shielding effect of the B-ring on H-6. Based on the empirical rule, the chemical shift values of the A-ring in methyl barceloneate were revised. The possible biosynthesis of these isolates was postulated. Betaethrin H showed moderate cytotoxicity against MCF-7 and HepG2 cancer cell lines. Betaethrins A-F, H and I displayed strong antioxidant activities. These results further implied that endophytic fungi from unique environments, such as desert plants, with few chemical studies are an important resource of undescribed and bioactive metabolites.

Abstract
Fungi are a rich source of secondary metabolites with potent biological activities. Co-culturing a fungus with another microorganism has drawn much attention as a practical method for stimulating fungal secondary metabolism. However, in most cases, the molecular mechanisms underlying the activation of secondary metabolite production in co-culture are poorly understood. To elucidate such a mechanism, in this study, we established a model fungal-fungal co-culture system, composed of Aspergillus nidulans and Aspergillus fumigatus. In the co-culture of A. nidulans and A. fumigatus, production of antibacterial diphenyl ethers was enhanced. Transcriptome analysis by RNA-sequencing showed that the co-culture activated expression of siderophore biosynthesis genes in A. fumigatus and two polyketide biosynthetic gene clusters (the ors and cic clusters) in A. nidulans. Gene disruption experiments revealed that the ors cluster is responsible for diphenyl ether production in the co-culture. Interestingly, the ors cluster was previously reported to be upregulated by co-culture of A. nidulans with the bacterium Streptomyces rapamycinicus; orsellinic acid was the main product of the cluster in that co-culture. In other words, the main product of the ors cluster was different in fungal-fungal and bacterial-fungal co-culture. The genes responsible for biosynthesis of the bacterial- and fungal-induced polyketides were deduced using a heterologous expression system in Aspergillus oryzae. The molecular genetic mechanisms that trigger biosynthesis of two different types of compounds in A. nidulans in response to the fungus and the bacterium were demonstrated, which provides an insight into complex secondary metabolic response of fungi to microorganisms. KEY POINTS: • Co-culture of two fungal species triggered antibiotic diphenyl ether production. • The co-culture affected expression levels of several genes for secondary metabolism. • Gene cluster essential for induction of the antibiotics production was determined.

Abstract
Indole alkaloids are heterocyclic natural products with extensive pharmacological activities. As an important source of lead compounds, many clinical drugs have been derived from natural indole compounds. Marine indole alkaloids, from unique marine environments with high pressure, high salt and low temperature, exhibit structural diversity with various bioactivities, which attracts the attention of drug researchers. This article is a continuation of the previous two comprehensive reviews and covers the literature on marine indole alkaloids published from 2015 to 2021, with 472 new or structure-revised compounds categorized by sources into marine microorganisms, invertebrates, and plant-derived. The structures and bioactivities demonstrated in this article will benefit the synthesis and pharmacological activity study for marine indole alkaloids on their way to clinical drugs.
