catalyst for the solvent-free preparation of 3,3'-(arylmethylene)-bis(2-hydroxynaphthoquinone) 3,3′-(arylmethylene)-bis(2-hydroxynaphthalene-1,4-dione)} derivatives in high yields and relatively short times. The one-pot pseudo-multi-component reaction of 2-hydroxynaphthoquinone (2-hydroxynaphthalene-1,4-dione) (2 eq.) and arylaldehydes (1 eq.) has been used for the preparation of these compounds. Graphic

compared to cisplatin, thus indicating the superiority of 1j as a possible anticanceragent. This compound was observed to induceapoptosis in the glioma cells by inducing the caspasedependent apoptotic pathways via ROS and downregulating the PI3K/AKT/mTOR pathway. Estimation of different oxidative stress markers also confirms the induction of oxidative stress in 1j exposed cancer cells. The toxicity of 1j
