Abstract
Growing demand for the tasty and healthy food has driven the development of low-calorie sweeteners, sweet taste modulators, and bitter masking compounds originated from natural sources. With the discovery of human taste receptors, increasing numbers of sweet taste modulators have been identified through human taste response and molecular docking techniques. However, the discovery of novel taste-active molecules in nature can be accelerated by using advanced spectrometry technologies based on structure-activity relationships (SARs). SARs explain why structurally similar compounds can elicit similar taste qualities. Given the characterization of structural information from reported data, strategies employing SAR techniques to find structurally similar compounds become an innovative approach to expand knowledge of sweeteners. This review aims to summarize the structural patterns of known natural non-nutritive sweeteners, sweet taste enhancers, and bitter masking compounds. Innovative SAR-based approaches to explore sweetener derivatives are also discussed. Most sweet-tasting flavonoids belong to either the flavanonols or the dihydrochalcones and known bitter masking molecules are flavanones. Based on SAR findings that structural similarities are related to the sensory properties, innovative methodologies described in this paper can be applied to screen and discover the derivatives of taste-active compounds or potential taste modulators.

PHYTOCHEMISTRY 2021; 184:112666. [PMID: 33524858 DOI: 10.1016/j.phytochem.2021.112666] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/15/2020] [Revised: 01/06/2021] [Accepted: 01/09/2021] [Indexed: 06/12/2023]
Abstract
After anti-angiogenic activity screening, the potential n-butanol layer partitioned from the ethanol extract of Staurogyne concinnula was conducted. Further purification by Diaion HP20 column and preparative HPLC chromatography, four undescribed triterpenoid saponin derivatives, along with the known baptisiasaponin I, and four known phenylpropanoid glycosides were isolated and characterized from n-butanol layer. The structures of isolated compounds were elucidated by ESI-MS, 1D, and 2D MNR data. Biological evaluation revealed that baptisiasaponin I possessed significant anti-angiogenic effects (IC50 4.0 ± 0.2 μM). Further mechanism of action of baptisiasaponin I by inhibition of integrin/FAK/paxillin signaling pathway and its downstream effectors as MMP2 and MMP9 are also presented.
