    摘要: A method of enhancing the efficiency and increasing the duration of action of drugs (e.g. dihydropyridines and anti-bacterials) and particularly of nifedipine and penicillins wherein one or more hydrogen atoms are deuterated and wherein the deuterated drug has unexpectedly improved properties when used in much lower concentrations than unmodified drug. A method for determining the identity and bioequivalency of a new drug is also disclosed wherein the molecular and isotope structure of a new drug is determined by isotope ratio mass spectrometry and compared with the molecular and isotope structure of a known human drug.

    摘要: Cyclosporine derivatives are disclosed which possess enhanced efficacy and reduced toxicity over naturally occurring and other presently known cyclosporin and cyclosporine derivatives. The cyclosporine derivatives of the present invention are produced by chemical and isotopic substitution of the cyclosporine A (CsA) molecule by: (1) Chemical substitution and optionally deuterium substitution of amino acid 1; and (2) deuterium substitution at key sites of metabolism of the cyclosporine A molecule such as amino acids 1, 4, 9. Also disclosed are methods of producing the cyclosporine derivatives and method of producing immunosuppression with reduced toxicity with the disclosed cyclosporine derivatives.
