    • The invention relates to derivatives of 2-hydroxytetrahydrofuran corresponding to general formula (I) in which A represents the radical, in which R1, R2, R4, R5 and R6 represent (in particular), independently, H, a halogen atom, OH, alkyl or alkoxy, R3 represents H, alkyl or —COR10, R10 representing H, alkyl or alkoxy, and W represents a bond, —CH2—CH2—, —CH═CH—, —O—, —S— or —NR11— in which R11 represents H or alkyl; X represents —CO—, —Y—CO—, —O—Y—CO— or —NR12—Y—CO—, Y represents an alkylene or haloalkylene alkyl, R12 represents H, alkyl or —COR13, R13 represents H, alkyl, haloalkyl or alkoxy, AA represents, each time that it occurs, a natural or non-natural amino acid; n represents 2 or 3; and finally R represents H, alkyl or —CO—R19, R19 representing alkyl. These compounds have a calpain inhibiting activity and/or an activity which traps the reactive oxygen species and can be used for preparing a medicament intended to treat the inflammatory and immunological diseases, cardio-vascular and cerebro-vascular diseases, disorders of the central or peripheral nervous system, cachexia, osteoporosis, muscular dystrophy, proliferative diseases, cataract, rejection reactions following organ transplants and autoimmune and viral diseases.
