Queuine
Queuine is a highly modified derivative of guanine found in the first position of the anticodon of the transfer RNAs for asp, asn, his and tyr. The original transcripts of these tRNAs contain guanine in this position. All organisms with the exception of yeast and mycoplasma contain queuine. Bacteria synthesize queuine but it cannot be synthesized by higher mammals. Significant amounts of free queuine are present in common plant and animal food products.

S-(2-Methylpropionyl)-dihydrolipoamide-E
S-(2-Methylpropionyl)-dihydrolipoamide-E is an intermediate in valine, leucine and isoleucine degradation(KEGG ID C15977). It is the second to last step in the synthesis of branched chain fatty acid and is converted from 2-methyl-1-hydroxypropyl-ThPP via the enzyme 2-oxoisovalerate dehydrogenase [EC:1.2.4.4]. It is then converted to isobutyryl-CoA via the enzyme dihydrolipoyllysine-residue (2-methylpropanoyl)transferase [EC:2.3.1.168].

Methionyl-Glutamine
Methionyl-Glutamine is a dipeptide composed of methionine and glutamine. It is an incomplete breakdown product of protein digestion or protein catabolism. Some dipeptides are known to have physiological or cell-signaling effects although most are simply short-lived intermediates on their way to specific amino acid degradation pathways following further proteolysis. This dipeptide has not yet been identified in human tissues or biofluids and so it is classified as an Expected metabolite.
Entecavir
Entecavir is an oral antiviral drug used in the treatment of hepatitis B infection. It is marketed under the trade name Baraclude (BMS). Entecavir is a guanine analogue that inhibits all three steps in the viral replication process, and the manufacturer claims that it is more efficacious than previous agents used to treat hepatitis B (lamivudine and adefovir). It was approved by the U.S. Food and Drug Administration (FDA) in March 2005.
