Review of Oxepine-Pyrimidinone-Ketopiperazine Type Nonribosomal Peptides
H OH metabolites OH Review Review of Oxepine-Pyrimidinone-Ketopiperazine Type Nonribosomal Peptides Yaojie Guo , Jens C. Frisvad and Thomas O. Larsen * Department of Biotechnology and Biomedicine, Technical University of Denmark, Søltofts Plads, Building 221, DK-2800 Kgs. Lyngby, Denmark; [email protected] (Y.G.); [email protected] (J.C.F.) * Correspondence: [email protected]; Tel.: +45-4525-2632 Received: 12 May 2020; Accepted: 8 June 2020; Published: 15 June 2020 Abstract: Recently, a rare class of nonribosomal peptides (NRPs) bearing a unique Oxepine-Pyrimidinone-Ketopiperazine (OPK) scaffold has been exclusively isolated from fungal sources. Based on the number of rings and conjugation systems on the backbone, it can be further categorized into three types A, B, and C. These compounds have been applied to various bioassays, and some have exhibited promising bioactivities like antifungal activity against phytopathogenic fungi and transcriptional activation on liver X receptor α. This review summarizes all the research related to natural OPK NRPs, including their biological sources, chemical structures, bioassays, as well as proposed biosynthetic mechanisms from 1988 to March 2020. The taxonomy of the fungal sources and chirality-related issues of these products are also discussed. Keywords: oxepine; nonribosomal peptides; bioactivity; biosynthesis; fungi; Aspergillus 1. Introduction Nonribosomal peptides (NRPs), mostly found in bacteria and fungi, are a class of peptidyl secondary metabolites biosynthesized by large modularly organized multienzyme complexes named nonribosomal peptide synthetases (NRPSs) [1]. These products are amongst the most structurally diverse secondary metabolites in nature; they exhibit a broad range of activities, which have been exploited in treatments such as the immunosuppressant cyclosporine A and the antibiotic daptomycin [2,3]. -

Lists of Names in Aspergillus and Teleomorphs As Proposed by Pitt and Taylor, Mycologia, 106: 1051-1062, 2014 (Doi: 10.3852/14-0
Lists of names in Aspergillus and teleomorphs as proposed by Pitt and Taylor, Mycologia, 106: 1051-1062, 2014 (doi: 10.3852/14-060), based on retypification of Aspergillus with A. niger as type species John I. Pitt and John W. Taylor, CSIRO Food and Nutrition, North Ryde, NSW 2113, Australia and Dept of Plant and Microbial Biology, University of California, Berkeley, CA 94720-3102, USA Preamble The lists below set out the nomenclature of Aspergillus and its teleomorphs as they would become on acceptance of a proposal published by Pitt and Taylor (2014) to change the type species of Aspergillus from A. glaucus to A. niger. The central points of the proposal by Pitt and Taylor (2014) are that retypification of Aspergillus on A. niger will make the classification of fungi with Aspergillus anamorphs: i) reflect the great phenotypic diversity in sexual morphology, physiology and ecology of the clades whose species have Aspergillus anamorphs; ii) respect the phylogenetic relationship of these clades to each other and to Penicillium; and iii) preserve the name Aspergillus for the clade that contains the greatest number of economically important species. Specifically, of the 11 teleomorph genera associated with Aspergillus anamorphs, the proposal of Pitt and Taylor (2014) maintains the three major teleomorph genera – Eurotium, Neosartorya and Emericella – together with Chaetosartorya, Hemicarpenteles, Sclerocleista and Warcupiella. Aspergillus is maintained for the important species used industrially and for manufacture of fermented foods, together with all species producing major mycotoxins. The teleomorph genera Fennellia, Petromyces, Neocarpenteles and Neopetromyces are synonymised with Aspergillus. The lists below are based on the List of “Names in Current Use” developed by Pitt and Samson (1993) and those listed in MycoBank (www.MycoBank.org), plus extensive scrutiny of papers publishing new species of Aspergillus and associated teleomorph genera as collected in Index of Fungi (1992-2104). -

(2000). Observations on Aspergilli in Santa Rosa National Park, Costa Rica. Fungal Diversity 4: 81-100. Species of Aspergillus and their sexual states, Emericella, Eurotium, and Neosartorya, were isolated from soil or collected on natural substrata in Santa Rosa National Park in northwestern Costa Rica. Fungi were recovered by soil dilution plating, direct plating of soil on cyclosporine-containing media and direct plating on media used to recover osmotolerant and osmophilic fungi. We examined their distribution in soils collected at I-km intervals along an Il-kilometer transect on the Santa Elena Peninsula. A large and diverse group of Aspergillus species were isolated. Nine or more species were found at more than half of the sampling points along the transect. Some of the same species described from Costa Rica by Raper and Fennell were also recovered in this study. In addition to morphological identification, representatives of all Aspergillus species were subjected to DNA sequencing using the ITSI-5.8S-ITS2 regions and the 28S 01-02 regions. Sequencing selected regions of ribosomal DNA were an effective technique in the identification of Aspergillus. -

Clinical Relevance and Characteristics of Aspergillus Calidoustus and Other Aspergillus Species of Section Usti
Journal of Fungi Review Clinical Relevance and Characteristics of Aspergillus calidoustus and Other Aspergillus Species of Section Usti Emmanouil Glampedakis 1,Véronique Erard 2 and Frederic Lamoth 1,3,* 1 Infectious Diseases Service, Lausanne University Hospital and University of Lausanne, 1011 Lausanne, Switzerland; [email protected] 2 Clinique de Médecine et spécialités, infectiologie, HFR-Fribourg, 1708 Fribourg, Switzerland; [email protected] 3 Institute of Microbiology, Lausanne University Hospital and University of Lausanne, 1011 Lausanne, Switzerland * Correspondence: [email protected]; Tel.: +41-21-314-1010 Received: 30 April 2020; Accepted: 4 June 2020; Published: 12 June 2020 Abstract: The Aspergilli of section Usti (group ustus) are represented by over 20 species, of which Aspergillus calidoustus is the most relevant human pathogen. Invasive aspergillosis (IA) caused by these fungi is rare but could represent an emerging issue among the expanding population of patients with long-term immunosuppression receiving antifungal prophylaxis. Clinicians should be aware of this unusual type of IA, which often exhibits distinct clinical features, such as an insidious and prolonged course and a high occurrence of extra-pulmonary manifestations, such as skin/soft tissue or brain lesions. Moreover, these Aspergillus spp. pose a therapeutic challenge because of their decreased susceptibility to azole drugs. In this review, we outline the microbiological and clinical characteristics of IA due to Aspergillus spp. of section Usti and discuss the therapeutic options. Keywords: Aspergillus ustus; Aspergillus pseudodeflectus; Aspergillus granulosus; Aspergillus insuetus; Aspergillus puniceus; Aspergillus keveii; invasive aspergillosis 1. Introduction Fungi of the genus Aspergillus represent the most important pathogenic molds for humans, causing invasive aspergillosis (IA) in patients with impaired immune defenses. -

Lyngby, Denmark; 3Department of Microbiology, Faculty of Science and Informatics, University of Szeged, H-6701 Szeged, P.O. Box 533, Hungary *Correspondence: J. Houbraken, [email protected] Abstract: Aspergillus ustus is a very common species in foods, soil and indoor environments. Based on chemical, molecular and morphological data, A. insuetus is separated from A. ustus and revived. A. insuetus differs from A. ustus in producing drimans and ophiobolin G and H and not producing ustic acid and austocystins. The molecular, physiological and morphological data also indicated that another species, A. keveii sp. nov. is closely related but distinct from A. insuetus. Aspergillus section Usti sensu stricto includes 8 species: A. ustus, A. puniceus, A. granulosus, A. pseudodeflectus, A. calidoustus, A. insuetus and A. keveii together with Emericella heterothallica. Taxonomic novelties: Aspergillus insuetus revived, Aspergillus keveii sp. nov. Key words: actin, Aspergillus, β-tubulin, calmodulin, extrolite profiles, ITS, phylogenetics, polyphasic taxonomy. INTRODUCTION β-tubulin, calmodulin and actin genes, analysis of extrolite profiles, and macro- and micromorphological analysis of the isolates. Aspergillus ustus is a very common filamentous fungus found in foods, soil and indoor air environments (Samson et al. 2002). -

Current Research in Environmental & Applied Mycology 5(4), 285–306, Doi 10.5943/cream/5/4/1 Abstract The state of Gujarat is well known for its contrasting ecoregions such as moist deciduous forests and deserts. This paper deals with the documentation of fungi of Gujarat state. Field studies are carried out since 2007 in different parts of Gujarat to study the wood rot fungi that destroy wood logs in different forests. During these studies we noticed a great lacuna in documented record of fungi occurring in Gujarat. Here we provide, for the first time, a literature-based preliminary checklist of the fungi occurring in the state that is supplemented with our original field work and observations. It includes 334 species of 158 genera belonging to 78 families, which are further categorized into: Ascomycota (59 genera), Basidiomycota (85 genera), Chytridiomycota (2 genera), Oomycota (3 genera), “Zygomycota” (4 genera) and Myxomycota (5 genera). -

Lyngby, Denmark *Correspondence: R.A. Samson, [email protected] Abstract: Aspergillus comprises a diverse group of species based on morphological, physiological and phylogenetic characters, which significantly impact biotechnology, food production, indoor environments and human health. Aspergillus was traditionally associated with nine teleomorph genera, but phylogenetic data suggest that together with genera such as Polypaecilum, Phialosimplex, Dichotomomyces and Cristaspora, Aspergillus forms a monophyletic clade closely related to Penicillium. Changes in the International Code of Nomenclature for algae, fungi and plants resulted in the move to one name per species, meaning that a decision had to be made whether to keep Aspergillus as one big genus or to split it into several smaller genera.
