Abstract
An undescribed α-pyrone diaporpyrone E (1), and three known nucleotides, 5'-O-acetyl uridine (2), 5'-O-acetyl thymidine (3), and adenine (4), were identified from Diaporthe sp. CB10100, an endophytic fungus isolated from the medicinal plant Sinomenium acutum. The structure of 1 was determined by extensive analysis of its HRMS, 1D and 2D NMR spectroscopic data, as well as electronic circular dichroism calculations and comparison. The in vitro cytotoxic and antibacterial assays of 1 revealed that it has a 30.2% inhibitory effect on HepG2 cells at 50 μM, while no antibacterial activities against Staphylococcus aureus and Klebsiella pneumoniae at 64 μg/mL.

[PMID: 38064922 DOI: 10.1016/j.fitote.2023.105772] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/19/2023] [Revised: 11/16/2023] [Accepted: 12/02/2023] [Indexed: 01/12/2024]
Abstract
Three new compounds phomtersines A-C (1-3) together with nine known compounds were isolated from the marine-derived fungus Phomopsis tersa FS441. Their structures were sufficiently established by spectroscopic methods, including extensive 1D and 2D NMR techniques and modified Snatzke's method. Moreover, compounds 1-12 were evaluated for cytotoxic and anti-inflammatory activities. As a result, phomtersine B (2) and the known compound 10 showed moderate cytotoxic activity against the four tested cell lines with IC50 values ranging from 20.21 to 36.53 μM, and phomtersine A (1) exhibited moderate inhibitory activity against LPS-induced NO production.

[PMID: 34869205 PMCID: PMC8640094 DOI: 10.3389/fchem.2021.755351] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2021] [Accepted: 09/27/2021] [Indexed: 11/24/2022] Open
Abstract
Phytochemical investigation of Diaporthe foeniculina BZM-15 led to one new γ-butyrolactone derivative, diaportone A (1), one cyclopentenone derivative, diaportone B (3), and one monoterpene derivative, diaportone C (5), along with six known compounds (2, 4, and 6–9). Their structures as well as the absolute configurations were characterized by means of NMR, HRESIMS, and ECD spectroscopy and quantum chemistry calculation, respectively. Furthermore, all compounds were evaluated for their cytotoxic activity and antibacterial activity, and compounds 7 and 8 displayed significant antiproliferative effects on three human cancer cell lines (SF-268, MCF-7, and HepG2) with IC50 values ranging from 3.6 to 15.8 μM.
