Unlocking the Multifunctional Therapeutic Potential of Herbacetin: A Flavone derived Scaffold

Herbacetin (HBT), a naturally occurring flavone, exhibits broad therapeutic -- potential, including anti-cancer, anti-inflammatory, antioxidant, antimicrobial, neuroprotective, and anti-diabetic effects, by modulating key signaling pathways such as NF-κB, PI3K/AKT, AP-1, SGK1/FoxO1, AMPK, SIRT1, MMP9, and NLRP3. It also inhibits several critical enzymes, including ornithine decarboxylase, ATP-citrate lyase, SGK1, AChE, α-glucosidase, and CYP3A4. In the context of cancer, HBT has shown particularly promising activity against breast cancer, liver carcinoma, human colon cancer, and epidermal carcinoma. Structurally, HBT shares significant similarity with well-known flavonoids such as quercetin and kaempferol, and the availability of established total synthetic methodologies makes it an attractive candidate for synthetic chemists. However, the structural modification and comprehensive evaluation of ' 'HBT's biological activity remain underexplored. This review highlights its isolation, total synthesis, pharmacological properties, molecular targets, and future directions, emphasizing the versatility of the HBT scaffold as a promising foundation for the development of novel therapeutic agents.
