Abstract

Saponins encompass a diverse group of naturally occurring glycoside molecules exhibiting amphiphilic properties and a broad range of biological activities. There is a resurgence of interest in those saponins produced by marine organisms based on their potential therapeutic benefits, application in food products and most recently their potential involvement in intra- and inter-species chemical communication. The continual advancements in liquid chromatography techniques and mass spectrometry technologies have allowed for greater detection rates, as well as improved isolation and elucidation of saponins. These factors have significantly contributed to the expansion in the catalogue of known saponin structures isolated from marine invertebrates; however, there currently exists no specific chemical library resource to accelerate the discovery process. In this study, a Marine Animal Saponin Database (MASD v1.0) has been developed to serve as a valuable chemical repository for known marine saponin-related data, including chemical formula, molecular mass and biological origin of nearly 1000 secondary metabolites associated with saponins produced by marine invertebrates. We demonstrate its application with an exemplar asteroid extract (Acanthaster cf. solaris, also known as crown-of-thorns starfish; COTS), identifying saponins from the MASD v1.0 that have been previously reported from COTS, as well as 21 saponins isolated from multiple other related asteroid species. This database will help facilitate future research endeavours, aiding researchers in exploring the vast chemical diversity of saponins produced by marine organisms and providing ecological insights, and the realisation of their potential for various applications, including as pharmaceuticals.

用于鉴定海洋动物皂素相关代谢物的质谱数据库。
皂苷包含多种天然糖苷分子,具有两亲性和广泛的生物活性。由于海洋生物产生的皂苷具有潜在的治疗作用、可应用于食品,以及最近可能参与物种内和物种间的化学交流,人们对这些皂苷的兴趣再次升温。液相色谱技术和质谱技术的不断进步提高了皂苷的检测率,并改善了皂苷的分离和阐明。这些因素极大地促进了从海洋无脊椎动物中分离出的已知皂苷结构目录的扩大;然而,目前还没有特定的化学库资源来加速发现过程。本研究开发了海洋动物皂苷数据库(MASD v1.0),作为已知海洋皂苷相关数据(包括近 1000 种与海洋无脊椎动物产生的皂苷相关的次级代谢产物的化学式、分子质量和生物来源)的宝贵化学资料库。我们用一个示范性小行星提取物(Acanthaster cf. solaris,又称棘冠海星;COTS)演示了该数据库的应用,从 MASD v1.0 中识别出了以前从 COTS 中报道过的皂苷,以及从多个其他相关小行星物种中分离出的 21 种皂苷。该数据库将有助于促进未来的研究工作,帮助研究人员探索海洋生物产生的皂苷的巨大化学多样性,提供生态学见解,并实现其在包括制药在内的各种应用领域的潜力。
