Abstract
Pseudodiploöspora longispora (previously known as Diploöspora longispora) is a pathogenic fungus of Morchella mushrooms. The molecular mechanism underlying the infection of P. longispora in fruiting bodies remains unknown. In this study, three known peptaibols, alamethicin F-50, polysporin B, and septocylindrin B (1-3), and a new analogue, longisporin A (4), were detected and identified in the culture of P. longispora and the fruiting bodies of M. sextelata infected by P. longispora. The primary amino sequence of longisporin A is defined as Ac-Aib1-Pro2-Aib3-Ala4-Aib5-Aib6-Gln7-Aib8-Val9-Aib10-Glu11-Leu12-Aib13-Pro14-Val15-Aib16-Aib17-Gln18-Gln19-Phaol20. The peptaibols 1-4 greatly suppressed the mycelial growth of M. sextelata. In addition, treatment with alamethicin F-50 produced damage on the cell wall and membrane of M. sextelata. Compounds 1-4 also exhibited inhibitory activities against human pathogens including Aspergillus fumigatus, Candida albicans, methicillin-resistant Staphylococcus aureus and vancomycin-resistant Enterococcus, and plant pathogen Verticillium dahlia. Herein, peptaibols are confirmed as virulence factors involved in the invasion of P. longispora on Morchella, providing insights into the interaction between pathogenic P. longispora and mushrooms.

Abstract
Trichoderma, a genus with more than 400 species, has a long history of use as an industrial bioreactor, biofertilizer, and biocontrol agent. It is considered a significant source of secondary metabolites (SMs) that possess unique structural features and a wide range of bioactivities. In recent years, numerous secondary metabolites of Trichoderma, including terpenoids, polyketides, peptides, alkaloids, and steroids, have been identified. Most of these SMs displayed antimicrobial, cytotoxic, and antifungal effects. This review focuses on the structural diversity, biological activities, and structure-activity relationships (SARs) of the SMs isolated from Trichoderma covered from 2018 to 2022. This study provides insights into the exploration and utilization of bioactive compounds from Trichoderma species in the agriculture or pharmaceutical industry.

Abstract
Total 23 eleven-residue peptaibols, including five reported ones (1-5) in our previous work, were isolated from the fungus Trichoderma longibrachiatum Rifai DMG-3-1-1, which was obtained from the mushroom Clitocybe nebularis (Batsch) P. Kumm. The structures of the 13 new peptaibols (6-10 and 12-19) were determined by their NMR and MALDI-MS/MS data, their absolute structures were further determined by Marfey's analyses and their ECD data. Careful comparison of the structures of 1-23 showed that only seven residues varied including the 2nd (Gln 2 /Asn 2 ), 3rd (Ile 3 /Val 3 ), 4th (Ile 4 /Val 4 ), 6th (Pro 6 /Hyp 6 ), 8 th (Pro 6 /Hyp 6 ), 10th (Pro 10 /Hyp 10 ) and 11th (Leuol 11 /Ileol 11 /Valol 11 ) residues. Comparison of the IC 50 s against the three tested cell lines of 1-23 indicated that 2nd, 3rd and 4th amino acid residues affected their cytotoxicities powerfully. Compounds 2, 5, 9, 11, 21 and 22 showed moderate antibacterial activities against Staphylococcus aureus MRSA T144, which also showed stronger cytotoxicities against BV2 and MCF-7 cells.

Abstract
A recently discovered secondary metabolism regulator, NPD938, was used to alter the secondary metabolite profile in Fusarium sp. RK97-94. Three lucilactaene analogues were detected via UPLC-ESI-MS analysis in NPD938-treated culture. The three metabolites were successfully purified and identified as dihydroNG391 (1), dihydrolucilactaene (2), and 13α-hydroxylucilactaene (3) via extensive spectroscopic analyses. DihydroNG391 (1) exhibited weak in vitro antimalarial activity (IC50 = 62 μM). In contrast, dihydrolucilactaene (2) and 13α-hydroxylucilactaene (3) showed very potent antimalarial activity (IC50 = 0.0015 and 0.68 μM, respectively). These findings provide insight into the structure-activity relationship of lucilactaene and its analogues as antimalarial lead compounds.

Abstract
Fungal species of genus Sepedonium are rich sources of diverse secondary metabolites (e.g., alkaloids, peptaibols), which exhibit variable biological activities. Herein, two new peptaibols, named ampullosporin F (1) and ampullosporin G (2), together with five known compounds, ampullosporin A (3), peptaibolin (4), chrysosporide (5), c(Trp-Ser) (6) and c(Trp-Ala) (7), have been isolated from the culture of Sepedonium ampullosporum Damon strain KSH534. The structures of 1 and 2 were elucidated based on ESI-HRMSn experiments and intense 1D and 2D NMR analyses. The sequence of ampullosporin F (1) was determined to be Ac-Trp1-Ala2-Aib3-Aib4-Leu5-Aib6-Gln7-Aib8-Aib9-Aib10-GluOMe11-Leu12-Aib13-Gln14-Leuol15, while ampullosporin G (2) differs from 1 by exchanging the position of Gln7 with GluOMe11. Furthermore, the total synthesis of 1 and 2 was carried out on solid-phase to confirm the absolute configuration of all chiral amino acids as L. In addition, ampullosporin F (1) and G (2) showed significant antifungal activity against B. cinerea and P. infestans, but were inactive against S. tritici. Cell viability assays using human prostate (PC-3) and colorectal (HT-29) cancer cells confirmed potent anticancer activities of 1 and 2. Furthermore, a molecular docking study was performed in silico as an attempt to explain the structure-activity correlation of the characteristic ampullosporins (1–3).

Abstract
Six new 11-mer peptaibols designed as zealpeptaibolins, A - F were isolated from the soil fungus, Trichoderma sp. RK10-F026, based on the principal component analysis of the MS data from five different culture compositions. Previously, 20-mer peptaibols from the same fungal strain were identified; 11-mer peptaibols in contrast were discovered from a different culture condition, signifying peptaibol production was culture condition-dependent. These peptaibols contained three Aib-Pro motifs in the sequence. The structures were established by NMR and HR-MS experiments including detailed MS/MS fragmentations. The absolute configurations were determined by Marfey's analysis. Zealpeptaibolin F exhibited the strongest cytotoxicity toward K562 leukemia cells with an IC50 value of 0.91 µM.

Abstract
N-acetyl-α-hydroxy-β-oxotryptamine (1) along with N-acetyl-β-oxotryptamine (2) and pimprinine (3) were isolated from the culture broth of Streptomyces sp. 80H647. Compound 1 was found to be a racemate via X-ray diffraction analysis and the enantiomers were successfully purified by chiral-phase HPLC. The absolute configuration was assigned by comparison of the calculated and experimental ECD spectra. The α-hydroxy moiety of 1 was vital for cytotoxicity against different cancer cell lines.
