摘要:
N,N-substituted cyclic amine derivatives represented by general formula (VIII) or pharmacologically acceptable salts thereof: wherein A represents aryl, etc.; E represents -CO- or -CHOH-; G represents oxygen, etc.; J represents optionally substituted aryl; R1 represents lower alkyl, etc.; Alk represents linear or branched lower alkylene; n, v, w, x and y independently represent each 0 or 1; and p represents 2 or 3. These compounds or salts thereof are efficacious in treating diseases against which calcium antagonism is efficacious. These diseases include cerebrovascular disorder at the acute stage, cerebral stroke, cerebral infarction, head injury, cerebral nerve cell death, Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis, Huntington's disease, brain circulatory disturbance, brain function disturbance, pain, convulsion, schizophrenia, hemicrania, epilepsy, circular psychosis, nerve degeneration diseases, brain ischemia, AIDS, complex dementia, edema, anxiety and diabetic nephropathy.

摘要:
Novel compounds exhibiting excellent calcium antagonism, particularly neuroselective calcium antagonism, namely, compounds of the general formula (I), salts of the same, or hydrates of both wherein Ar is a group derived from an optionally substituted 5- to 14-membered aromatic ring, or the like; the ring A is one member selected from among piperazine, homopiperazine, piperidine and so on; the ring B is an optionally substituted C3-14 hydrocarbon ring or the like; E is a single bond, -CO-, or the like; X is a single bond, oxygen, or the like; R1 is hydrogen, halogeno, hydroxyl, or the like; and D?1, D2, W1 and W2¿ are each independently a single bond or optionally substituted C¿1-6? alkylene.
