Provided is a novel use of a plasminogen activator inhibitor-1 inhibitor (PAI-1 inhibitor) that is used as an active ingredient of an agent for controlling a tumor stem cell, an agent for enhancing the antitumor effect of an antitumor agent, an agent for tumor chemotherapy, a stem-cell protecting drug, or a hematopoietic disorder improving agent.

Use for PAI-1 inhibitor

The present invention provides a method for diagnosing schizophrenia, and a schizophrenia diagnostic reagent or device for use in the method. The present invention further provides a therapeutic or ameliorating agent for schizophrenia, which is effective for the treatment or amelioration of schizophrenia. The therapeutic or ameliorating agent for schizophrenia contains a carbonyl scavenger or a carbonyl-modified protein formation inhibitor as an active ingredient. The method for diagnosing schizophrenia according to the present invention includes measuring at least one parameter in a subject, the parameter being selected from the group consisting of: (1) a genetic abnormality of glyoxalase I gene; (2) the expression level or activity of glyoxalase I in a biological sample; (3) the amount of a carbonyl compound or a carbonyl-modified protein that is a protein modified with the carbonyl compound; and (4) the amount of pyridoxal in a biological sample.

Detection and treatment of schizophrenia

Inhibitor of plasminogen activator inhibitor-1

The present invention relates to an inhibitor of plasminogen activator inhibitor-1. The present invention further relates to a pharmaceutical composition that has an inhibitory action on PAI-1 activity and is useful in the prevention and treatment of various diseases whose onset is associated with PAI-1 activity. Furthermore, the present invention relates to a novel compound having PAI-1 inhibitory activity represented by the following general formula (I), and a salt thereof. Each symbol is defined as those in the specification.

Carbonyl compounds generated and accumulated in the peritoneal dialysate can be inactivated or eliminated by a carbonyl compound-trapping agent such as aminoguanidine. Carbonyl compounds generated during sterilization and storage of the peritoneal dialysate can be eliminated by pre-contacting with the trapping agent. Further, it is possible to eliminate carbonyl compounds transferred from the blood to the peritoneal cavity of the patient during peritoneal dialysis treatment, by adding the trapping agent to the peritoneal dialysate or by circulating the fluid through a carbonyl compound-trapping cartridge. Intraperitoneal protein modification by carbonyl compounds is inhibited by the present invention, thereby sufficiently reducing peritoneal disorders associated with peritoneal dialysis treatment.

Method for preparing peritoneal dialysate

To provide a inhibitor of protein modification products formation capable of inhibiting of vitamin B6 deficiency disease as a side effect, especially a renal protective agent. There is provided a use, as an active ingredient, of any of free or salt-form compounds of either of the formulae: (I) (II) [wherein R1 is substituted or unsubstituted aromatic ring; and each of R2, R3 and R4 is a hydrogen atom or monovalent organic group, or alternatively R2 and R3 cooperate to form a condensed ring or R3 and R4 cooperate to represent a divalent organic group, provided that R3 and R4 are not simultaneously hydrogen atoms]. 

Inhibitor of protein modification products formation

The present invention provides a compound represented by the following formula (I) wherein A is a cyclic group etc., B is a 1H-tetrazol-5-yl group or a 2,4-dioxothiazolidin-5-yl group, and Y is a single bond or a C6-10 arylene group, or a pharmacologically acceptable salt thereof or an ester thereof.

A gene expressed specifically in mesangial cells. A DNA expressed specifically in mesangial cells; a protein encoded by this DNA; an antibody binding to this protein, etc. These substances are indigenous to mesangial cells and, therefore, useful in, for example, identifying mesangial cells and detecting abnormalities in mesangial cells. Moreover, the above protein would be helpful for clarification of the functions of masangial cells and, in its turn, for clarification of the causes of diseases relating to masangial cells. This protein is expectedly applicable to the treatment and diagnosis of diseases relating to masangial cells.

MEGSIN protein

The present invention provides agents that decrease carbonyl stress comprising biguanides, such as metoformin. Through oral administration and such, the carbonyl stress-decreasing agents of the present invention are useful as drugs directly acting against carbonyl stress in vivo.
