Abstract
Two new prenylxanthone derivatives, asperidulins A (1) and B (2), along with a known emodin analogue (3) were isolated from an apple-derived fungus Aspergillus nidulans KIB-HACM-01. Their structures were elucidated by interpretation of HRMS, NMR, and comparisons of specific optical rotation. Asperidulin B (2) exhibited a moderate cytotoxicity against A549 and BEAS-2B with an IC50 values of 13.62 ± 0.41 and 11.27 ± 0.52 μM, and methyl-averantin (3) showed moderate cytotoxicities against all six tested cell lines (HL-60, A549, SMMC-7721, MDA-MB-231, SW480, BEAS-2B) with IC50 values ranging from 8.93 ± 0.56 to 35.27 ± 0.25 μM.

Description of Streptomyces naphthomycinicus sp. nov., an endophytic actinobacterium producing naphthomycin A and its genome insight for discovering bioactive compounds. Front Microbiol 2024; 15:1353511. [PMID: 38694805 PMCID: PMC11061393 DOI: 10.3389/fmicb.2024.1353511] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/10/2023] [Accepted: 04/01/2024] [Indexed: 05/04/2024] Open
Abstract
Endophytic actinobacteria are a group of bacteria living inside plant tissue without harmful effects, and benefit the host plant. Many can inhibit plant pathogens and promote plant growth. This study aimed to identify a strain of Streptomyces as a novel species and study its antibiotics production. An endophytic actinobacterium, strain TML10T was isolated from a surface-sterilized leaf of a Thai medicinal plant (Terminalia mucronata Craib and Hutch). As a result of a polyphasic taxonomy study, strain TML10T was identified as a member of the genus Streptomyces. Strain TML10T was an aerobic actinobacterium with well-developed substrate mycelia with loop spore chains and spiny surface. Chemotaxonomic data, including cell wall components, major menaquinones, and major fatty acids, confirmed the affiliation of strain TML10T to the genus Streptomyces. The results of the phylogenetic analysis, including physiological and biochemical studies in combination with a genome comparison study, allowed the genotypic and phenotypic differentiation of strain TML10T and the closest related type strains. The digital DNA-DNA hybridization (dDDH), Average nucleotide identity Blast (ANIb), and ANIMummer (ANIm) values between strain TML10T and the closest type strain, Streptomyces musisoli CH5-8T were 38.8%, 88.5%, and 90.8%, respectively. The name proposed for the new species is Streptomyces naphthomycinicus sp. nov. (TML10T = TBRC 15050T = NRRL B-65638T). Strain TML10T was further studied for liquid and solid-state fermentation of antibiotic production. Solid-state fermentation with cooked rice provided the best conditions for antibiotic production against methicillin-resistant Staphylococcus aureus. The elucidation of the chemical structures from this strain revealed a known antimicrobial agent, naphthomycin A. Mining the genome data of strain TML10T suggested its potential as a producer of antbiotics and other valuable compounds such as ε-Poly-L-lysine (ε-PL) and arginine deiminase. Strain TML10T contains the arcA gene encoding arginine deiminase and could degrade arginine in vitro.

Abstract
Two naphthoquinone-derived heterodimers with unprecedented carbon skeletons, eleucanainones A (1) and B (2), were isolated from the bulbs of Eleutherine americana. Their structures were elucidated by comprehensive spectroscopic methods. The structures of 1 and 2 were determined to be the first examples of dibenzofuran- and naphthalenone-containing naphthoquinone dimers. Compound 1 exhibited significant anti-MRSA activity in vitro with minimum inhibitory concentration (MIC) values of 0.78 μg/mL by downregulation of basal expression of agrA, cidA, icaA and sarA in methicillin-resistant S. aureus (MRSA).

Abstract
Seven new trialkyl-substituted benzene derivatives named benwamycins A-G (1-7), together with three known congeners, 8-10, were isolated from culture broth of the soil-derived Streptomyces sp. KIB-H1471. Their structures were elucidated by using 1D and 2D NMR analyses in combination with HRESIMS data. The absolute configurations of 1-9 were determined by chemical conversion and comparison of circular dichroism spectra and confirmed for 1 by single-crystal X-ray crystallography. Compounds 6 and 7 have a unique γ-pyrone-like ring on one side chain. Compounds 2 and 6 inhibited human T cell proliferation with IC50 values of 14.3 and 12.5 μM, respectively, without obvious cytotoxicity for naïve human T cells. Compounds 3 and 6 could weakly enhance insulin-stimulated glucose uptake.
