Hinokitiol (HK), a monoterpenoid that naturally occurs in plants belonging to the Cupressaceae family, possesses important biological activities, including an anticancer effect. This review summarizes its anticancer potential and draws possible molecular interventions. In addition, it evaluates the biopharmaceutical, toxicological properties, and clinical application of HK to establish its viability for future advancement as a dependable anticancer medication. The assessment is based on the most recent information available from various databases. Findings demonstrate that HK possesses substantial therapeutic advantages against diverse types of cancer (colon, cervical, breast, bone, endometrial, liver, prostate, oral, and skin) through various molecular mechanisms. HK induces oxidative stress, cytotoxicity, apoptosis, cell-cycle arrest at the G and S phases, and autophagy through modulation of phosphatidylinositol 3-kinase (PI3K)/Akt/mammalian target of rapamycin (mTOR), p38/ERK/MAPK, nuclear factor kappa B, and c-Jun N-terminal kinase signaling pathways. Furthermore, this compound exhibits good oral bioavailability with excellent plasma clearance. Clinical uses of HK demonstrate therapeutic advantages without any significant negative effects. A thorough study of the pertinent data suggests that HK may serve as a viable candidate for developing novel cancer therapies. Consequently, more extensive studies are necessary to evaluate its cancer treatment efficacy, safety, and possible long-term hazards.
