MgO-ZnO nanoparticle as an efficient photocatalyst in the synthesis of substituted chromeno[4, 3-b]chromenes as effective drugs in gastrointestinal cancer therapy

Abstract

Chromeno[4,3-b]chromenes are biologically active compounds that have many applications in medicine, especially, in gastrointestinal field because of their anti-inflammatory and antioxidant properties. In this study, an efficient and environmental benign photocatalyst MgO-ZnO is proposed for the synthesis of a range of substituted chromenes under irradiation of a common green laser. To characterize MgO-ZnO techniques such as FT-IR, DRS, XRD, and FE-SEM are employed to ascertain the structure and physicochemical properties of the nanomaterial. Furthermore, an in-vitro cellular toxicity test was achieved on HCT-116 human gastrointestinal cancer cell line by MTT assay.
