Pharmacological applications of farnesol (C 15 H 26 O): a patent review.

Introduction: Farnesol (C15H26O) is a sesquiterpene alcohol found in essential oils. This substance is reported to have different pharmacological activities such as antimicrobial, antitumor and antioxidant effects, as well as actions in different body systems. Areas covered: This study aimed to analyze pharmaceutical patents containing this substance in their formulations. Patent search was carried out through the WIPO (World Intellectual Property Organization), LatiPat and INPI (National Institute of Industrial Property) electronic banks using the following descriptors and combinations: 'farnesol', 'pharmaceutical product', 'pharmacology' and 'pharmacy'. Expert opinion: Primary research identified 54 patents, from which 17 were selected for the final analysis after applying the inclusion criteria. The selected patents referred to products presenting different pharmaceutical activities of interest such as the prevention and treatment of diseases affecting the dermis, central nervous and cardiovascular systems, diseases caused by different microorganisms and cancers, among others. A minority of the articles included in this review reported the type of farnesol isomer that was investigated, this becoming a major limitation for the development of future pharmaceutical products. With the completion of this study, farnesol presents itself as a potential agent with pharmacological application both in the prevention and treatment of different diseases.
