Metabolite Identification
Common NameAnthrone
DescriptionAnthrone, also known as 9-oxoanthracene or az-O, belongs to the class of organic compounds known as anthracenes. These are organic compounds containing a system of three linearly fused benzene rings. Based on a literature review a significant number of articles have been published on Anthrone. This compound has been identified in human blood as reported by (PMID: 31557052 ). Anthrone is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Anthrone is part of the human exposome. The exposome can be defined as the collection of all the exposures of an individual in a lifetime and how those exposures relate to health. An individual's exposure begins before birth and includes insults from environmental and occupational sources.

Specific function:
Atrochrysone carboxyl ACP thioesterase; part of the gene cluster that mediates the biosynthesis of trypacidin, a mycotoxin with antiprotozoal activity and that plays a role in the infection process (PubMed:26278536, PubMed:26242966). The pathway begins with the synthesis of atrochrysone thioester by the polyketide synthase (PKS) tpcC (PubMed:26242966). The atrochrysone carboxyl ACP thioesterase tpcB then breaks the thioester bond and releases the atrochrysone carboxylic acid from tpcC (PubMed:26242966). The decarboxylase tpcK converts atrochrysone carboxylic acid to atrochrysone which is further reduced into emodin anthrone (PubMed:26242966). The next step is performed by the emodin anthrone oxygenase tpcL that catalyzes the oxidation of emodin anthrone to emodin (PubMed:26242966). Emodin O-methyltransferase encoded by tpcA catalyzes methylation of the 8-hydroxy group of emodin to form questin (PubMed:26242966). Ring cleavage of questin by questin oxidase tpcI leads to desmethylsulochrin via several intermediates including questin epoxide (By similarity). Another methylation step catalyzed by tpcM leads to the formation of sulochrin which is further converted to monomethylsulfochrin by tpcH. Finally, the tpcJ catalyzes the conversion of monomethylsulfochrin to trypacidin (PubMed:26242966). Trypacidin is toxic for human pulmonary and bronchial epithelial cells by initiating the intracellular formation of nitric oxide (NO) and hydrogen peroxide (H(2)O(2)), thus triggering host necrotic cell death (PubMed:22319557). The trypacidin pathway is also able to produce endocrocin via a distinct route from the endocrocin Enc pathway (PubMed:26242966).

Finally, the tpcJ catalyzes the conversion of monomethylsulfochrin to trypacidin (PubMed:26242966). Trypacidin is toxic for human pulmonary and bronchial epithelial cells by initiating the intracellular formation of nitric oxide (NO) and hydrogen peroxide (H(2)O(2)), thus triggering host necrotic cell death (PubMed:22319557). The trypacidin pathway is also able to produce endocrocin via a distinct route from the endocrocin Enc pathway (PubMed:26242966).
