Chemometric‐based drug discovery approaches from natural origins using hyphenated chromatographic techniques

Introduction Isolation and characterization of bioactive components from complex matrices of marine or terrestrial biological origins are the most challenging issues for natural product chemists. Biochemometric is a new potential scope in natural product analytical science, and it is a methodology to find the compound's correlation to their bioactivity with the help of hyphenated chromatographic techniques and chemometric tools. Objectives The present review aims to evaluate the application of chemometric tools coupled to chromatographic techniques for drug discovery from natural resources. Methods The searching keywords “biochemometric,” “chemometric,” “chromatography,” “natural products bioassay,” and “bioassay” were selected to search the published articles between 2010‐2023 using different search engines including “Pubmed”, “Web of Science,” “ScienceDirect,” and “Google scholar.” Results An initial stage in natural product analysis is applying the chromatographic hyphenated techniques in conjunction with biochemometric approaches. Among the applied chromatographic techniques, liquid chromatography (LC) techniques, have taken up more than half (53%) and also, mass spectroscopy (MS)‐based chromatographic techniques such as LC–MS are the most widely used techniques applied in combination with chemometric methods for natural products bioassay. Considering the complexity of dataset achieved from chromatographic hyphenated techniques, chemometric tools have been increasingly employed for phytochemical studies in the context of determining botanicals geographical origin, quality control, and detection of bioactive compounds. Conclusion Biochemometric application is expected to be further improved with advancing in data acquisition methods, new efficient preprocessing, model validation and variable selection methods which would guarantee that the applied model to have good prediction ability in compound relation to its bioactivity. Biochemometric is a new approach in the bioactive natural‐products discovery that correlates compound's detection analytical signals to their bioactivity with the help of chemometric tools. The present review paper suggests among the hyphenated chromatographic techniques, liquid chromatography (LC) techniques have taken up more than half (53%) and mass spectroscopy (MS)‐based chromatographic detecting systems are the most applied ones in this scope. Biochemometric application is expected to be further improved with advancing in data
