Bioactive small molecules are organic compounds that have a low molecular weight (900 daltons). Most pharmaceutical drugs are small molecules. Larger structures such as nucleic acids, proteins, and many polysaccharides are not small molecules.
Flumequine is a broad-spectrum, first-generation fluoroquinolone commonly used in veterinary research. It was patented in 1973 by Riker Labs. Flumequine is freely soluble in alkaline solutions and ethanol but is insoluble in water. Mechanism of...
