Phenyl 1-hydroxy-2-naphthoate, liquid crystal Intermediate
Intermediate for the synthesis of natural products and anti-carcinogenic compounds, liquid crystal intermediates.
Phenyl 1-Hydroxy-2-naphthoate (PHN) is a phenyl ester of 1-hydroxy-2-naphthoic acid. Hydroxynaphthoate derivatives are well known for their biological and medicinal properties. The 1-hydroxy-2-naphthoate moiety has been discovered in natural products such as the cytotoxic compounds 3-hydroxymollugin and 3-methoxymollugin. For their biological and medicinal properties, hydroxynaphthoates play an important role in drug discovery and they have been used as intermediates for the synthesis of the anti-carcinogenic compounds.
Research also shows that both methyl 1-hydroxy-2-naphthoate and ethyl 1,6-dihydroxy-2-naphthoate develop anti-inflammatory activity, while 1-hydroxy-2-naphthoic acid itself has been recognized as an antibacterial agent.
