Guggulsterone as a dual-function steroidal scaffold: Cholesterol modulation and bioenhancement potential against...

Area of Science:

• Biochemistry
• Pharmacology
• Nanotechnology

Background:

• 7-Ketocholesterol (7-KC) is a cytotoxic product of cholesterol oxidation implicated in various diseases.
• Existing treatments like statins fail to address pre-formed oxysterols, creating a therapeutic gap.
• Oxysterol accumulation drives oxidative stress, inflammation, and apoptosis in critical organ systems.

Purpose of the Study:

• To evaluate Guggulsterone (GGS) as a therapeutic agent against 7-KC-related pathologies.
• To explore GGS's mechanisms, including its antioxidant, anti-inflammatory, and cholesterol efflux-enhancing properties.
• To investigate the potential of nanocarrier-based formulations for GGS delivery.

Main Methods:

• Investigated GGS's effects on 7-KC formation and cellular resilience.
• Assessed GGS's impact on cholesterol efflux pathways (LDLR, ABC transporters).
• Explored GGS incorporation into advanced nanocarrier systems (SEDDS, nanoparticles, SLNs).

Main Results:

• GGS demonstrated antioxidant, anti-inflammatory, and Nrf2-activating effects, reducing 7-KC generation.
• GGS enhanced cholesterol efflux and improved cellular resistance to oxysterol-induced apoptosis.
• Nanocarrier formulations improved GGS bioavailability, stability, and tissue targeting, including brain penetration.

Conclusions:

• Guggulsterone presents a dual therapeutic strategy by reducing 7-KC and enhancing cholesterol clearance.
• Its ability to improve cellular resilience and bioavailability via nanodelivery is significant.
• GGS offers a promising approach to manage oxysterol burden and improve outcomes in related disorders.
