Abstract:
PROBLEM TO BE SOLVED: To obtain the subject new compound used as an intermediate for synthesizing compounds inhibiting the proteases of retroviruses, especially the protease of human immunodeficiency virus causing human acquired immunodeficiency syndrome and for synthesizing medicines for treating the disease. SOLUTION: Compounds of formulas I and II (R is H, a lower alkyl), e.g. N-(((benzyl)oxy)carbonyl)-L-phenylalaninal. The compound of formula I, etc., is obtained e.g. by binding a protected O-aminoaldehyde of formula III to a compound of the formula VCl3 (tetrahydrofuran)3 and Zn to produce a diol mixture, isolating a compound of formula IV, and subsequently hydrolyzing the isolated compound of formula IV with Ba(OH)2 to produce an aminodiol of formula V.

Abstract:
PROBLEM TO BE SOLVED: To provide a method for improving the pharmacokinetics of drugs metabolized by cytochrome P450 monooxygenases. SOLUTION: The method comprises combination administration of ritonavir or a pharmaceutically acceptable salt thereof. When the ritonavir is administered in combination with drugs metabolized by the cytochrome P450 monooxygenases, two sorts of these therapeutic agents can be prescribed as a separate formulation administered at a simultaneous or different time, or these two sorts of therapeutic agents can be administered as a single formulation.
