Cancer is one of the deadliest and most heterogeneous diseases. Cancers often develop drug resistance, which can lead to treatment failure or recurrence. Accordingly, anticancer compounds are essential for chemotherapy-resistant cancer cells. Phenolic compounds are of interest in the development of cancer drugs due to their medicinal properties and ability to target different molecular pathways. Gallic acid (GA), as one of the main components of phenol, which is abundantly present in plant compounds such as walnut, sumac, grapes, tea leaves, oak bark, and other plant compounds, has antitumor properties. GA can prevent cancer progression, cell invasion, and metastasis by targeting molecular pathways and is an effective complement to chemotherapy drugs and combating multidrug resistance (MDR). In this review, we discuss various mechanisms related to cancer, the therapeutic potential of GA, the antitumor properties of GA in various cancers, and the targeted delivery of GA with nanocarriers.
Keywords: Cancer; Drug resistance; Gallic acid; Molecular pathway.
