Common Name(1r,10s,12r)-4-methoxy-9-azatetracyclo[7.5.2.0¹,¹⁰.0²,⁷]hexadeca-2(7),3,5,13-tetraene-5,12-diol
DescriptionSiculine belongs to the class of organic compounds known as phenanthridines and derivatives. These are polycyclic compounds containing a phenanthridine moiety, which is a tricyclic system with two benzene rings joined by a pyridine forming a non-linear skeleton. Hydrogenated derivatives are also included. (1r,10s,12r)-4-methoxy-9-azatetracyclo[7.5.2.0¹,¹⁰.0²,⁷]hexadeca-2(7),3,5,13-tetraene-5,12-diol is found in Crinum asiaticum and Sternbergia lutea. (1r,10s,12r)-4-methoxy-9-azatetracyclo[7.5.2.0¹,¹⁰.0²,⁷]hexadeca-2(7),3,5,13-tetraene-5,12-diol was first documented in 2009 (PMID: 19003939). Based on a literature review a small amount of articles have been published on Siculine (PMID: 21314165) (PMID: 35662286).
