Protective effect of Clinacanthus nutans in cisplatin‐induced nephrotoxicity on human kidney cell (PCS‐400‐010) elucidated by an LCMS‐based metabolomics approach

Abstract

Cisplatin‐induced nephrotoxicity has been widely reported in numerous studies. The objective of this study is to assess the potential nephroprotective effects of Clinacanthus nutans (Burm. f.) Lindau (Acanthaceae) leaf extracts on human kidney cells (PCS‐400‐010) in vitro using an LCMS‐based metabolomics approach. Orthogonal partial least square‐discriminant analysis identified 16 significantly altered metabolites when comparing the control and pre‐treated C. nutans cisplatin‐induced groups. These metabolites were found to be associated with glycerophospholipid, purine, and amino acid metabolism, as well as the glycolysis pathway. Pre‐treatment with C. nutans aqueous extract (125 μg/mL) for 24 h, followed by 48 h of cisplatin induction in PCS‐400‐010 cells, demonstrated a nephroprotective effect, particularly involving the regulation of amino acid metabolism.
