Chlorzoxazone

5-chloro-2,3-dihydro-1,3-benzoxazol-2-one

C7H4ClNO2 (168.9931)

A centrally acting central muscle relaxant with sedative properties. It is claimed to inhibit muscle spasm by exerting an effect primarily at the level of the spinal cord and subcortical areas of the brain.

Selenocysteine

(2R)-2-Amino-3-selanylpropanoic acid

C3H7NO2Se (168.9642)

Selenocysteine is an amino acid that is present in several enzymes (for example glutathione peroxidases, tetraiodothyronine 5 deiodinases, thioredoxin reductases, formate dehydrogenases, glycine reductases and some hydrogenases). Selenocysteine has a structure similar to cysteine, but with an atom of selenium taking the place of the usual sulfur. Proteins that include a selenocysteine residue are called selenoproteins (Wikipedia). Selenocysteine is a naturally occurring amino acid in both eukaryotic and prokaryotic organisms. It is found in tRNAs and in the catalytic site of some enzymes. The genes for glutathione peroxidase and formate dehydrogenase contain the TGA codon, which codes for this amino acid (Pubchem). Formed by seleniferous plants, e.g. onion, cabbage

Thulium

Tm (168.9342)

Thulium, also known as 69tm or tulio, is a member of the class of compounds known as homogeneous lanthanide compounds. Homogeneous lanthanide compounds are inorganic compounds containing only metal atoms, with the largest atom being a lanthanide atom. Thulium is a chemical element with symbol Tm and atomic number 69. It is the thirteenth and third-last element in the lanthanide series. Like the other lanthanides, the most common oxidation state is +3, seen in its oxide, halides and other compounds; because it occurs so late in the series, however, the +2 oxidation state is also stabilized by the nearly full 4f shell that results. In aqueous solution, like compounds of other late lanthanides, soluble thulium compounds form coordination complexes with nine water molecules .
