Citronellol (CT) is a naturally occurring lipophilic monoterpenoid which has shown anticancer effects in numerous cancerous cell lines. This study was, therefore, designed to examine CT's potential as an anticancer agent against glioblastoma (GBM). Network pharmacology analysis was employed to identify potential anticancer targets of CT. A comprehensive data mining was carried out to assess CT and GBM-associated target genes. Protein–protein interaction network was constructed to identify hub genes and later GO and KEGG enrichment analysis was performed to elucidate the possible mechanism. Human glioblastoma cell line “SF767” was used to confirm in silico findings. MTT, crystal violet, and trypan blue assays were performed to assess the cytotoxic effects of various concentrations of CT. Subsequently, ELISA and qPCR were performed to analyze the effects of CT on proapoptotic and inflammatory mediators. In silico findings indicated that CT differentially regulated proapoptotic and inflammatory pathways by activating caspase-3 and 8 and inhibiting nuclear factor-kappa B (NF-κB), tumor necrosis factor-α, Janus kinase 2 (JAK2). Molecular docking also demonstrated strong binding affinities of CT with the above-mentioned mediators when compared to 5-fluorouracil or temozolomide. In SF767 cell line, CT displayed dose-dependent cytotoxic and antioxidant effects, and upregulation of annexin-V, caspase-3, and 8 along with downregulation of inflammatory modulators. In a nutshell, it can be concluded from these findings that CT possesses robust anticancer activity which is mediated via differential regulation of caspase-3, JAK2, and NF-κB pathways.
