Description

Neoechinulin A is a member of the isoprenyl indole alkaloid chemical class, primarily isolated from the marine fungus Aspergillus amstelodami. Its chemical structure features a complex indole framework with isoprenyl substituents, contributing to its diverse biological activities. Neoechinulin A has garnered attention for its anti-inflammatory properties and recently identified antioomycete effects, particularly against pathogens like Phytophthora capsici (PMID:40843946 ). Analytical techniques such as high-performance liquid chromatography-mass spectrometry (HPLC-MS) have revealed its presence in various natural extracts, including FBT-baijiu, where it coexists with other alkaloids like eurocristatine and echinulin (PMID:39644119 ). The optimization of extraction methods has led to enhanced yields of neoechinulin A, with specific parameters yielding up to 1.500 mg/g (PMID:38792694 ). Furthermore, it has been identified as a significant compound in metabolomic studies, indicating its potential roles in various biochemical pathways (PMID:38163185 ). The isolation and characterization of neoechinulin A alongside other related alkaloids underscore its importance in natural product chemistry and its potential applications in pharmacology (PMID:37277707 ; PMID:36986059 ).
