PURPOSE: To obtain a new compound having activity for inhibiting the migration and proliferation of cells caused by stimulation with a cell migration growth factor, especially a platelet-derived growth factor and capable of providing a prophylactic and therapeutic agent for ischemic cardiopathy, arteriosclerosis, etc.
CONSTITUTION: This compound is represented by formula I or II [B is 0 or S; A is CH2, CO or SO2; R is a halogen; (n) is 0-5] or its salt, e.g. 1-(3,4- dichlorobenzoyl)-3-(4-oxo-2-thioxo-5-thiazolidinylidene)-2-indolinone. The compound is obtained by reacting, e.g. isatin represented by formula III with a compound represented by formula IV in the presence of a base such as triethylamine in an inert solvent such as DMF and then reacting the resultant N-substituted isatin derivative with a heterocyclic compound represented by formula V in the presence of a basic compound as a reaction accelerator in an aromatic hydrocarbon solvent such as toluene.

2. Description of the Related Art In recent years, it has been elucidated that cell migration growth factors are involved in various diseases, and cell migration and proliferation caused by stimulation of these factors are associated with acute myocardial infarction and angina pectoris. Deeply involved in the pathogenesis of various diseases such as coronary arteriosclerosis, stenosis, ischemic heart disease due to occlusion, arteriosclerosis, interstitial lung fibrosis, osteoarthritis, chronic rheumatoid arthritis, nephrosis, and cancer Has been reported. For example, in chronic coronary stenosis disease with arteriosclerosis as the etiological background, platelets aggregate and cell growth factors such as PDGF are released at the damaged site as a result of damage to the intima due to risk factors such as hypertension and hyperlipidemia. It is known that the stimulation causes migration of medial smooth muscle cells.
In addition, the cause of chronic re-occlusion after percutaneous coronary dilatation (PTCA), which is used as a treatment method for arterial occlusion disease, is
Platelet aggregates at the damaged sites of the expanded intima and media, and cell migration growth factors such as PDGF are released, which induces migration of medial smooth muscle cells to the intima, resulting in revascularization. Is what happens. As represented by these, migration and proliferation of smooth muscle cells are involved in the pathogenesis of diseases related to stenosis / occlusion of blood vessels, and these migration / proliferation are caused by stimulation of cell migration growth factors such as PDGF. It is known to be brought.
