[PMID: 38058102 DOI: 10.1080/14786419.2023.2288242] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2023] [Accepted: 11/19/2023] [Indexed: 12/08/2023]
Abstract
One new lycopodine-type alkaloid (1), one new natural product (2), and eight known analogs (3-10) were isolated from the whole plants of Lycopodium japonicum Thunb. The structures of 1-10 were determined based on extensive comprehensive spectroscopic analyses, including UV, IR, NMR, and HRESIMS. Moreover, the isolated alkaloids were evaluated for their neuroprotective activity against Hemin-induced HT22 cell damage. Notably, compounds 1 and 10 exhibited potential neuroprotective activities, with 21.45% and 20.55% increase in cell survival at 20 μM, respectively. Moreover, compounds 1 and 10 revealed protective effects on Hemin-induced apoptosis in HT22 cells.

[PMID: 37966166 DOI: 10.1002/cbdv.202301449] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/18/2023] [Revised: 11/13/2023] [Accepted: 11/14/2023] [Indexed: 11/16/2023]
Abstract
One new fawcettimine-type alkaloid, phlecarinadine A (1), and twelve known ones (2-13) were isolated from the whole plant of Phlegmariurus carinatus. Their chemical structures were unambiguously established by extensive spectroscopic analyses, including nuclear magnetic resonance (NMR) spectroscopic and high resolution electrospray ionization mass spectrometry (HR-ESI-MS). The absolute configuration of 1 was elucidated by the electronic circular dichroism (ECD) technique. These compounds were tested for their cytotoxic and neuroprotective activities. None of these compounds revealed cytotoxic activity against five tumor cells. Phlegmariurine B (2) exhibited potential neuroprotective effects against hemin-induced HT22 cell damage, with a 17.76 % increase in cell survival at 10 μM. In further study, 2 can ameliorate hemin-induced neuronal cell death via an anti-apoptotic pathway. These findings suggest that 2 might be a valuable lead compound with neuroprotective activity.
