Zhang X, Song Q, Zheng H, Wang R, Zhang Q. Toxicity and Metabolomic Dysfunction Invoked by Febrifugin, a Harmful Component of Edible Nut of Swietenia macrophylla. Int J Mol Sci 2024; 25:9753. [PMID: 39273700 PMCID: PMC11396426 DOI: 10.3390/ijms25179753] [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: 08/06/2024] [Revised: 09/03/2024] [Accepted: 09/05/2024] [Indexed: 09/15/2024] Open
Abstract
Swietenia macrophylla fruit is a valuable and historically significant medicinal plant with anti-hypertension and anti-diabetes. We identified a toxic component, Febrifugin, from the edible part of the nut following zebrafish toxicity-guided isolation. Febrifugin is a mexicanolide-type limonoid compound. The toxic factor induced acute toxicity in zebrafish, including yolk sac edema and pericardial edema, reduced body length, decreased melanin deposition, and presented acute skeletal developmental issues. Further exploration of the acute toxicity mechanism through metabolomics revealed that Febrifugin caused significant changes in 13 metabolites in zebrafish larvae, which are involved in the pentose phosphate, tricarboxylic acid (TCA) cycle, and amino acid biosynthesis. The bioassay of oxidative stress capacity and qRT-PCR measurement showed that the compound significantly affected the h6pd gene in the pentose phosphate pathway and the mRNA expression of cs, idh3a, fh, and shda genes in the TCA cycle, leading to reactive oxygen species (ROS) accumulation and a notable decrease in glutathione (GSH) activity in zebrafish. These findings provide a basis for the rational use of S. macrophylla as a medicinal plant and raise awareness of the safety of medicinal plants.

[PMID: 37866424 DOI: 10.1016/j.fitote.2023.105708] [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: 08/09/2023] [Revised: 10/18/2023] [Accepted: 10/19/2023] [Indexed: 10/24/2023]
Abstract
Five undescribed triterpenoids and steroids (1-5), as well as ten known compounds, were purified from the branches and leaves of Cipadessa baccifera. Notably, 1 and 2 are rare cipadesin-type limonoids with an unusual 8,30-epoxide ring and 1,8-ether linkage, respectively. Compound 5 possessed pregnane steroid skeleton with an uncommon 5/6/6/6/5-fused ring system. Their structures were constructed by extensive spectroscopic analysis (NMR, IR, UV, and HRESIMS), and their absolute configurations were confirmed by ECD calculations and quantum chemical calculations. All the isolates were in vitro assayed for their antimicrobial potentials against 6 pathogenic microorganisms and antiproliferation activities against five human cancer cell lines. As a result, compounds 5, 12, 13, and 14 exhibited moderate antibacterial activities (MIC: 25-50 μg/mL). Moreover, 5 showed cytotoxicity against five cancer cell lines with IC50 values ranging from 8.0 to 19.9 μM.

Abstract
Eleven undescribed limonoids, cipacinerasins A-K, involving of four diverse carbon skeletal types, along with fifteen known analogues, were isolated from the branches and leaves of Cipadessa baccifera. Within them, cipacinerasins A and B feature a rearranged tetrahydropyranyl ring B formed between C-8 and C-30, are unusual miscellaneous-type limonoids. Cipacinerasins E and F are rare trijugin-type limonoids, of which the D-ring δ-lactone is cleaved. Their structures were elucidated on the basis of extensive spectroscopic data (HRESIMS, NMR, UV and IR), electronic circular dichroism (ECD) calculations, and single-crystal X-ray diffraction analysis. All compounds were evaluated in vitro cytotoxicity against five human tumor cell lines (K562, HeLa, PC3, LN-Cap and Hell), and cipacinerasin E showed moderate antitumor activity with IC50 values ranging from 8.0 to 24.8 μM.

Abstract
Covering: July 2010 to December 2021Limonoids, a kind of natural tetranortriterpenoids with diverse skeletons and valuable insecticidal and medicinal bioactivities, are the characteristic metabolites of most plants of the Meliaceae family. The chemistry and bioactivities of meliaceous limonoids are a continuing hot area of natural products research; to date, about 2700 meliaceous limonoids have been identified. In particular, more than 1600, including thirty kinds of novel rearranged skeletons, have been isolated and identified in the past decade due to their wide distribution and abundant content in Meliaceae plants and active biosynthetic pathways. In addition to the discovery of new structures, many positive medicinal bioactivities of meliaceous limonoids have been investigated, and extensive achievements regarding the chemical and biological synthesis have been made. This review summarizes the recent research progress in the discovery of new structures, medicinal and agricultural bioactivities, and chem/biosynthesis of limonoids from the plants of the Meliaceae family during the past decade, with an emphasis on the discovery of limonoids with novel skeletons, the medicinal bioactivities and mechanisms, and chemical synthesis. The structures, origins, and bioactivities of other new limonoids were provided as ESI. Studies published from July 2010 to December 2021 are reviewed, and 482 references are cited.

Abstract
Alzheimer's disease (AD) is a severe neurodegenerative disorder of different brain regions accompanied by distresses and affecting more than 25 million people in the world. This progressive brain deterioration affects the central nervous system and has negative impacts on a patient's daily activities such as memory impairment. The most important challenge concerning AD is the development of new drugs for long-term treatment or prevention, with lesser side effects and greater efficiency as cholinesterases inhibitors and the ability to remove amyloid-beta(Aβ) deposits and other related AD neuropathologies. Natural sources provide promising alternatives to synthetic cholinesterase inhibitors and many have been reported for alkaloids while neglecting other classes with potential cholinesterase inhibition. This review summarizes information about the therapeutic potential of small natural molecules from medicinal herbs, belonging to terpenoids, coumarins, and phenolic compounds, and others, which have gained special attention due to their specific modes of action and their advantages of low toxicity and high efficiency in the treatment of AD. Some show superior drug-like features in comparison to synthetic cholinesterase inhibitors. We expect that the listed phytoconstituents in this review will serve as promising tools and chemical scaffolds for the discovery of new potent therapeutic leads for the amelioration and treatment of Alzheimer's disease.
