Organic compounds that contain technetium as an integral part of the molecule. These compounds are often used as radionuclide imaging agents.
The location of the atoms, groups or ions relative to one another in a molecule, as well as the number, type and location of covalent bonds.
Inorganic or organic compounds that contain sulfur as an integral part of the molecule.
Volatile Organic Compounds
Organic compounds that have a relatively high VAPOR PRESSURE at room temperature.
The relationship between the chemical structure of a compound and its biological or pharmacological activity. Compounds are often classed together because they have structural characteristics in common including shape, size, stereochemical arrangement, and distribution of functional groups.
Concentrated pharmaceutical preparations of plants obtained by removing active constituents with a suitable solvent, which is evaporated away, and adjusting the residue to a prescribed standard.
Drug Evaluation, Preclinical
Preclinical testing of drugs in experimental animals or in vitro for their biological and toxic effects and potential clinical applications.
