摘要Background:Kalanchoe pinnata,commonly known as“air plant”or“miracle leaf,”has been widely used in traditional medicine for its analgesic,wound-healing,anti-stress,and dermatological properties.Chronic stress can disrupt the gut microbiome,leading to both physical and mental health issues.Notably,the interplay between inflammatory skin diseases and anxiety is known to cause dysbiosis in gut microbiota.Given the gut-skin axis,the present study explores the prebiotic potential of K.pinnata phytocompounds in promoting anxiolytic effects and skin restoration through modulation of the gut microbiota.Methods:In vivo behavioural assays and histopathological evaluations were performed to assess the physiological effects of K.pinnata.GC-MS analysis identified key phytocompounds,which were further subjected to in silico studies.Network pharmacology analyses,including KEGG pathway mapping,gene ontology,and protein-protein interaction analysis,were conducted to determine gene targets associated with inflammatory skin disease,anxiety disorders,and inflammatory bowel diseases.Molecular docking studies were performed to validate the interactions between bioactive compounds and the identified hub genes.Results:Behavioural and histopathological studies revealed significant restorative effects of K.pinnata on both gut and skin tissues.Capillary microclots and aggregation were notably reduced.Two key bioactive compounds—4-(Benzoyl methyl)-6-Methyl-2H-1,4-Benzoxazin-3-One and 2-Fluoro-5-Trifluoromethyl Benzoic Acid,Pentyl Ester—demonstrated intense interaction with 10 hub genes(PTGS2,EGFR,MAPK3,SRC,NFKB1,CCND1,JAK2,ICAM1,HSP90AA1,and MMP9).Docking analysis revealed a strong binding affinity of 4-(Benzoyl methyl)-6-methyl-2H-1,4-benzoxazin-3-one with PTGS2(binding energy:−9.83 kcal/mol),suggesting a potential mechanism for modulating COX-2-mediated inflammatory responses.Conclusion:The study endorses the therapeutic potential of K.pinnata in modulating the gut-brain-skin axis through its prebiotic and anti-inflammatory activities.Specifically,it highlights the ability of its bioactive compounds to target PTGS2,a key enzyme in inflammation,supporting its application in treating anxiety,skin inflammation,and gut dysbiosis-related disorders.
