4',5',7',17'-tetrahydroxy-14',18'-dimethyl-9',16'-dioxo-3',10'-dioxaspiro[oxirane-2,6'-pentacyclo[9.8.0.0¹,⁷.0⁴,¹⁹.0¹³,¹⁸]nonadecan]-14'-en-8'-yl acetate

Description

4',5',7',17'-Tetrahydroxy-14',18'-dimethyl-9',16'-dioxo-3',10'-dioxaspiro[oxirane-2,6'-pentacyclo[9.8.0.0¹,⁷.0⁴,¹⁹.0¹³,¹⁸]Nonadecan]-14'-en-8'-yl acetate belongs to the class of organic compounds known as quassinoids. These are a group of compounds chemically degraded from triterpenes. According to their basic skeleton, quassinoids are categorized into five distinct groups, C-18, C-19, C-20, C-22 and C-25 types. The C-20 quassinoids can be further classified into two types, tetracyclic and the pentacyclic. The tetracyclic variety does not have oxygenation at C-20, while the pentacyclic quassinoids possess additional oxygenation at C-20 that allows for the formation of an additional ring. 4',5',7',17'-tetrahydroxy-14',18'-dimethyl-9',16'-dioxo-3',10'-dioxaspiro[oxirane-2,6'-pentacyclo[9.8.0.0¹,⁷.0⁴,¹⁹.0¹³,¹⁸]nonadecan]-14'-en-8'-yl acetate is found in Eurycoma longifolia. 4',5',7',17'-Tetrahydroxy-14',18'-dimethyl-9',16'-dioxo-3',10'-dioxaspiro[oxirane-2,6'-pentacyclo[9.8.0.0¹,⁷.0⁴,¹⁹.0¹³,¹⁸]Nonadecan]-14'-en-8'-yl acetate is an extremely weak basic (essentially neutral) compound (based on its pKa).

Chemical Taxonomy

Description

Belongs to the class of organic compounds known as quassinoids. These are a group of compounds chemically degraded from triterpenes. According to their basic skeleton, quassinoids are categorized into five distinct groups, C-18, C-19, C-20, C-22 and C-25 types. The C-20 quassinoids can be further classified into two types, tetracyclic and the pentacyclic. The tetracyclic variety does not have oxygenation at C-20, while the pentacyclic quassinoids possess additional oxygenation at C-20 that allows for the formation of an additional ring.
