The invention relates to conformation-constrained entirely-synthetic macrocyclic compounds. A conformation-constrained, space-defined 12-30-member macrocyclic system (I) which is as shown in the description comprises three different constitution units: an aromatic template a, a confor1ation regulator b and a spaced part c, which are illustrated in the description and the claims. The macrocyclic compounds (I) can be easily prepared according to a parallel synthesis method or a combinatorial chemistry method, and are designed for realizing interaction with a specific biological target. Particularly, the compounds show agonistic or antagonistic activity to the following matters: a motilin receptor (MR), a 5-hydroxytryptamine receptor (5-HT2B receptor) of a subtype 5-HT2B, and a prostaglandin F2alpha receptor (FP receptor). Thus, the compounds are effectively used for treating gastrointestinal tract hypomotility disorder such as diabetic gastroparesis and constipation-predominant irritable bowel syndrome, CNS-related diseases such as migraine, schizophrenia, psychosis and depression, ocular hypertension such as glaucoma-related ocular hypertension, and premature delivery.

Molecular cloning and expression of a prostaglandin F2alpha receptor which is linked to the signal transduction pathways via guanine nucleotide binding regulatory (G) proteins and measured by, for example, cAMP, IP3 or intracellular calcium. By constructing cell lines that express a prostaglandin F2alpha receptor, the affinities and efficacies of agonist and antagonist drugs with the receptor can be assessed. A recombinant DNA construct includes a vector and a DNA fragment encoding a prostaglandin F2alpha receptor. A host cell is transformed with a recombinant DNA construct, so that the DNA fragment is expressed and a prostaglandin F2alpha receptor is produced. Suitable host systems include eukaryotic and prokaryotic cells, especially mamalian cells such as rat or human. Additionally, for diagnostic purposes, antibodies to a prostaglandin F2alpha receptor can be prepared by producing all or a portion of the receptor protein and injecting these into various types of mammals. Using the resulting antibodies, expression of an F2alpha receptor cDNA, i.e. receptor protein in tissue and cells can be measured.

The invention belongs to the technical field of biological medicine and relates to application of CD4+ T cell-derived BACE1 and/or prostaglandin E2 receptor EP2 and/or EP4 as a therapeutic target of Alzheimer's disease. It is found for the first time that CD4 + T cell-derived BACE1 can specifically shear prostaglandin synthetase precursor protein mPGES2, so that the maturation of mPGES2 is promoted, synthesis of prostaglandin PGE2 is promoted through mature mPGES2, and therefore, abnormal activation of CD4 + T cells is caused; meanwhile, the CD4 + T cells are abnormally activated and the expression of BACE1 is increased in AD patient and AD mouse models; meanwhile, the PGE2 receptor EP2/EP4 antagonist can improve the pathological phenotype of the Alzheimer's disease. Therefore, the CD4 + T cell-derived BACE1 and/or EP2 and/or EP4 can be used as a target for treating the Alzheimer's disease, and a new target is provided for researching a novel medicine for treating the Alzheimer's disease.
