cis,cis-Muconic acid
cis-cis-Muconic acid is a presumptive metabolite of benzene. Muconic acid was first isolated from the urine of rabbits and dogs in 1909 (M. Jaffe, Z Physiol Chem 62:58-67). It was originally thought that if muconic acid was formed by the opening of the benzene ring in vivo then the cis-cis isomer should be the initial (and primary) product. However subsequent studies conducted in the 1950s proved that trans-trans-muconic acid is a true metabolite of benzene in mammals (Parke DV, Williams RT. Biochem J 51:339-348 (1952)). Furthermore, dosing rabbits with phenol or catechol also resulted in the urinary excretion of trans-trans-muconic acid. The oxidative ring opening of benzene first gives rise to cis-cis-muconaldehyde, which then isomerizes to cis-trans- and trans-trans-muconaldehyde; the latter is oxidized in vivo to trans-trans-muconic acid. Isomerization of the trans-trans form may take place in vivo to yield small amounts if the cis-cis and cis-trans form of muconic acid. cis-cis-Muconic acid may also be generated from microbial fermentation of benzoic acid. Certain strains of arthobacter are particularly efficient at this process. cis-cis-Muconic acid can also be found in Pseudomonas and Escherichia coli (https://link.springer.com/article/10.1007/BF00250491) (PMID:26360870).

Sumiki's acid
Sumikis acid is a naturally occurring human metabolite (PMID:949837). Sumikis acid was first identified in the urine of a leukemic patient who was excreting an abnormal amount of its glycine derivative (PMID:5043270). Sumikis acid was found to be excreted by normal subjects after a phenylalanine loading, while heterozygotes for phenylketonuria dont excrete it (instead, they excrete 2-hydroxybenzeneacetic acid) (PMID:4708049). Patients receiving furan-containing sugar solutions i.v. convert 50\\\\% of the 5-hydroxymethyl-2-furfural into Sumikis acid (PMID:4202014). Sumikis acid has been found to be a byproduct of the fungus Aspergillus and probably other species of fungi and yeast as well. Sumikis acid is a naturally occurring human metabolite.
