(1r,2r,4r,8s,9r,10s,13s,16r)-2,8,16-trihydroxy-9-(hydroxymethyl)-5,5-dimethyl-14-methylidenetetracyclo[11.2.1.0¹,¹⁰.0⁴,⁹]hexadecan-15-one

Description

Kamebakaurin belongs to the class of organic compounds known as kaurane diterpenoids. These are diterpene alkaloids with a structure that is based on the kaurane skeleton. Kaurane is a tetracyclic compound that arises by cyclisation of a pimarane precursor followed by rearrangement. It possesses a [3,2,1]-bicyclic ring system with C15-C16 bridge connected to C13, forming the five-membered ring D. (1r,2r,4r,8s,9r,10s,13s,16r)-2,8,16-trihydroxy-9-(hydroxymethyl)-5,5-dimethyl-14-methylidenetetracyclo[11.2.1.0¹,¹⁰.0⁴,⁹]hexadecan-15-one is found in Isodon excisus, Isodon inflexus, Isodon japonicus, Isodon longitubus and Isodon umbrosus. (1r,2r,4r,8s,9r,10s,13s,16r)-2,8,16-trihydroxy-9-(hydroxymethyl)-5,5-dimethyl-14-methylidenetetracyclo[11.2.1.0¹,¹⁰.0⁴,⁹]hexadecan-15-one was first documented in 2016 (PMID: 26781327). Based on a literature review a small amount of articles have been published on kamebakaurin (PMID: 29320879) (PMID: 31468670) (PMID: 30333432) (PMID: 28624597).

Chemical Taxonomy

Description

Belongs to the class of organic compounds known as kaurane diterpenoids. These are diterpene alkaloids with a structure that is based on the kaurane skeleton. Kaurane is a tetracyclic compound that arises by cyclisation of a pimarane precursor followed by rearrangement. It possesses a [3,2,1]-bicyclic ring system with C15-C16 bridge connected to C13, forming the five-membered ring D.
