A compound having the formula (I):
for use in treating disease; a composition comprising said fused quinonic compound of formula (I) and at least one pharmaceutically acceptable carrier; as well as a method of modulating a Janus Kinase-Signal Transduction and Activators of Transcription (JAK-STAT) pathway. The activation of a JAK-STAT pathway is associated with several disease states such as immunological and inflammatory diseases, hyperproliferative disorders including cancer, and myeloproliferative diseases.
Described here is the first enantioselective total synthesis of lantalucratin C, which was isolated from the rainforest plant Lantana involucrata, and which possesses anti-tumor activity. The OH group on the aromatic ring was systematically introduced by an appropriate management of the OH protectinggroups. The alkyl side chain connected to a chiral carbon center was incorporated by directed ortho-lithiation
Unusual, chemoselective etherification of 2-hydroxy-1,4-naphthoquinone derivatives utilizing alkoxymethyl chlorides: scope, mechanism and application to the synthesis of biologically active natural product (±)-lantalucratin C
A novel etherification of 2-hydroxy-1,4-naphthoquinone derivatives with alkoxyalkyl chlorides and hydride bases is described. Precise study of the conditions and substrate scope suggested that the reaction occurs specifically in the molecule having a 2-hydroxy-1,4-benzoquinone skeleton. A chemoselective O-methylation reaction was achieved to afford a synthetically important intermediate, which offered

Palladium(II)-Catalyzed Reaction of Lawsones and Propargyl Carbonates: Construction of 2,3-Furanonaphthoquinones and Evaluation as Potential Indoleamine 2,3-Dioxygenase Inhibitors
An efficient reaction utilizing propargyl carbonates through Claisen rearrangement to synthesize furanonaphthoquinones is described. The remarkable transformation exhibits excellent functional group tolerance, affording the target furanonaphthoquinones in moderate to good yields (41–85%) undermildreactionconditions. Scaled-up preparation of the model product can make this reaction a method of choice
