Demeclocycline
Demeclocycline is only found in individuals that have used or taken this drug. It is a tetracycline analog having a 7-chloro and a 6-methyl. Because it is excreted more slowly than tetracycline, it maintains effective blood levels for longer periods of time. [PubChem]Demeclocycline inhibits cell growth by inhibiting translation. It binds (reversibly) to the 30S and 50S ribosomal subunit and prevents the amino-acyl tRNA from binding to the A site of the ribosome, which impairs protein synthesis by bacteria. The binding is reversible in nature. The use in SIADH actually relies on a side-effect of tetracycline antibiotics; many may cause diabetes insipidus (dehydration due to the inability to concentrate urine). It is not completely understood why demeclocycline impairs the action of antidiuretic hormone, but it is thought that it blocks the binding of the hormone to its receptor.

Tetracyclines are polyketides having an octahydrotetracene-2-carboxamide skeleton, substituted with many hydroxy and other groups (4as,5as,12as)-7-chloro-4-(dimethylamino)-3,6,10,12,12a-pentahydroxy-1,11-dioxo-1,4,4a,5,5a,6,11,12a-octahydrotetracene-2-carboximidic acid is considered to be a practically insoluble (in water) and an extremely strong acidic compound (4as,5as,12as)-7-chloro-4-(dimethylamino)-3,6,10,12,12a-pentahydroxy-1,11-dioxo-1,4,4a,5,5a,6,11,12a-octahydrotetracene-2-carboximidic acid can be found in humans.
Demeclocycline
Tetracycline which lacks the methyl substituent at position 7 and in which the hydrogen para- to the phenolic hydroxy group is substituted by chlorine. Like tetracycline, it is an antibiotic, but being excreted more slowly, effective blood levels are maintained for longer. It is used (mainly as the hydrochloride) for the treatment of Lyme disease, acne and bronchitis, as well as for hyponatraemia (low blood sodium concentration) due to the syndrome of inappropriate antidiuretic hormone (SIADH) where fluid restriction alone has been ineffective.
