Design and synthesis of novel quinic acid derivatives: cytotoxicity and anticancer effect on glioblastoma.

Quinic acid (QA) is a cyclic polyol exhibiting anticancer properties on several cancers. However, potential role of QA derivatives against glioblastoma is not well established. Sixteen novel QA derivatives and QA- encapsulated poly (lactic-co-glycolic acid) nanoparticles (QA--NPs) were screened for their anti-glioblastoma effect using standard cell and molecular biology methods. Presence of a tertiary hydroxy and silylether groups in the lead compound were identified for the antitumor activity. QA- have 90% inhibition with the IC of 10.66 μM and 28.22 μM for LN229 and SNB19, respectively. The induction of apoptosis is faster with the increased fold change of caspase 3/7 and reactive oxygen species. QA- and QA--NPs shows similar cytotoxicity effect, providing the opportunity to use QA- as a potential chemotherapeutic agent.
