Meclocycline sulfosalicylate is a salt prepared from demeclocycline by taking advantage of the basic dimethylamino group, which protonates and readily forms a salt in solution with 2-hydroxy-3-carboxybenzenesulfonic acid. Like all tetracyclines, meclocycline shows broad-spectrum antibacterial and antiprotozoan activity. The unusual complex counter-ion is likely to add an antiseptic component to the use of the compound for skin infections.
Meclocycline sulfosalicylate is soluble in ethanol, methanol, DMF or DMSO. Good water solubility.
