    摘要: A novel purine derivative exhibiting an effect to control inflammatory symptoms characteristic to nephritis and a medicine comprising this compound as an effective ingredient are provided. The compound is represented by the following general formula (I), wherein R1 is a hydrocarbon group having 17 or less carbon atoms and R2 is a hydrocarbon group having 16 or less carbon atoms, wherein one or more CH2 g roups in the hydrocarbon group which 7013 do not directly bind with the carbon atom at 2 or 7 position of the purine ring replaced are by carbonyl groups, sulfonyl groups, O, or S and/or one or more CH groups in the hydrocarbon group which do not directly bind with the carbon atom at 2 or 7 position of the purine ring are replaced by N, C-halogen, or C—C≡N, or a pharmaceutically acceptable salt thereof.

    摘要: A process for producing peptide derivatives of formula (1) or salts thereof: ##STR1## which comprises condensation of peptide derivative of formula (2): ##STR2## with carboxylic acid of formula (3): ##STR3## or condensation of a peptide derivative of formula (4): ##STR4## with a protected amino acid of formula (5'): ##STR5## wherein R.sup.1 and R.sup.2 are a lower alkyl group or hydrogen atom, R.sup.3 is a lower alkyl group, X is a methylthiomethyl, methanesulfonylmethyl, carbamoylmethyl, or a lower alkyl group, Ar is an aryl or heteroaryl group, and A.sup.4 is Ar--O--CH.sub.2 --CO. The peptide derivatives and salts thereof are useful as the human immunodeficiency virus (HIV) protease inhibitors.
