What is Dinaphtho[2,3-b:2',3'-d]thiophene-5,7,12,13-tetrone?

Description

Seriniquinone (22200-69-7) is a new natural product isolated from a marine bacterium of the genus Serinicoccus. Displays selective toxicity against a distinct set of cell lines (within the NCI 60 panel) predominantly melanoma. Upon cellular treatment, seriniquinone was found to localize in the endoplasmic reticulum. Within 3 hours cells underwent autophagy followed by death via a caspase-9 apoptotic pathway. The target of seriniquinone was identified as the small protein, dermcidin, as determined using an immunoaffinity approach.1
