摘要:
A preventive and remedy for diarrhea containing conagenin or a salt thereof as the active ingredient, capable of intensely suppressing particularly a diarrheic symptom accompanying the administration of cancer chemotherapeutics to thereby permit perennial cancer chemotherapy, and capable of preventing exhaustion of the physical strength of a patient to thereby enhance the therapeutic effect.

摘要:
D-β-Lysylmethanediamine represented by formula (I) or a salt or hydrate thereof has an activity of inhibiting the infection with AIDS virus or HIV, and hence an AIDS virus infection inhibitor containing the same as an active ingredient is prospective as one of the remedies for AIDS which is thought to be difficult to cure.

摘要:
A sulphostin analogue represented by the general formula, wherein n is an integer of from 0 to 3, provided that a case where n is 2 and steric configurations of C* and P* are S and R, respeetively, is excluded, or a pharmaceutically acceptable salt thereof.
摘要:
The invention provides 5-deoxy-5,5-difluoro derivatives of aminoglycoside antibiotics of neamine, kanamycin A, kanamycin B, gentamicin and seldomycin, each synthesized as a novel compound, and also 1-N-(α-hydroxy-φ-aminoalkanoyl) derivatives synthesized from the newly obtained 5-deoxy-5,5-difluorokanamycins A and B and analogs thereof. The 5-deoxy-5,5-difluoro derivatives thus obtained have antibacterial activities superior or substantially equivalent to those of the amino-glycoside antibiotics from which they are derived and further have a remarkably improved median lethal dose (LD50) when intravenously administered to mice and a remarkably reduced toxicity on mammals.
摘要:
A novel pyrrolidine derivative represented by general formula (1) or a pharmaceutically acceptable salt thereof, having a prolyl endopeptidase inhibitor activity and promising as an active ingredient of an antiamnetic. In said formula R1 represents (1) lower alkyl (C₁-C₆) or (2) an optionally substituted hydrocarbon ring group (a 3- to 15-membered monocyclic or fused-ring group); n and m represent each an integer and the sum of them represents an integer of 0 to 2; X and E represent each oxygen. NR' (wherein R' represents hydrogen or C₁-C₆ alkyl), sulfur, phenylene, CH=CH or CH₂; A represents an amino acid or imino acid residue wherein the functional group(s) may be substituted, or a glycine residue wherein the amino group may be substituted; and Y1 represents C₃-C₈ cycloalkyl.
