Combinational therapies are accompanied by severe side effects and significant financial burden, highlighting the urgent need for alternative, low toxicity treatments. This study sought to investigate the therapeutic efficacy of a new synthetic chalcone molecule, SHG-44, and its cellular mechanistic actions in U87MG and U251MG glioblastoma cell line models.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sec002\">\n<jats:title>Methods<\/jats:title>\n<jats:p>The effect of SHG-44 on glioblastoma cell viability, clonogenic survival, and cell migration was assessed using <jats:italic><jats:italic>in vitro<\/jats:italic><\/jats:italic> functional assays. Cellular reactive oxygen species levels were quantified to investigate oxidative stress induced by SHG-44. The induction of apoptosis by SHG-44 was examined through nuclear fragmentation analysis and acridine orange\/ethidium bromide staining. Small RNA-sequencing was performed to explore the regulatory effects of SHG44 on microRNA expression. The pharmacokinetic and pharmacodynamic properties of SHG-44 were evaluated through <jats:italic><jats:italic>in-silico<\/jats:italic><\/jats:italic> analysis.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sec003\">\n<jats:title>Results<\/jats:title>\n<jats:p>Cell viability assays demonstrated that SHG-44 significantly reduced cell viability in glioblastoma cells, with half-maximal inhibitory concentration of 70.39\u039c\u039c and 64.19\u039c\u039c in U87MG and U251MG cells, respectively. In line with these findings, a colony formation assay revealed a significant impairment of glioblastoma cells\u2019 clonogenic survival. SHG-44 effects on cell migration demonstrated a substantial abrogation of cell migration at 100\u039c\u039c SHG-44 within both glioblastoma cell lines. Cellular reactive oxygen species quantification showed a significant increase of ROS at 40\u039c\u039c SHG-44 concentrations within U87MG cells and a non-significant elevation of ROS within U251MG cells. Nuclear fragmentation and acridine orange\/ethidium bromide staining demonstrated that SHG-44 mediated cytotoxicity in U87MG and U251MG through apoptosis induction. Small RNA-sequencing analysis demonstrated that SHG-44 could regulate various cellular pathways through microRNA expression modulation in glioblastoma cell models. Further <jats:italic><jats:italic>in-silico<\/jats:italic><\/jats:italic> analysis of the pharmacokinetics and pharmacodynamics properties of SHG-44 demonstrated that the compound possessed sufficient absorption, distribution, potential to pass through the blood brain barrier, and low oral toxicity characteristics.<\/jats:p>\n<\/jats:sec>\n<jats:sec
