Abstract
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 motilinreceptor (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.
Description
[0001] This application is a divisional application whose parent application is Chinese invention patent application 200980160767.8. technical field [0002] Macrocyclic natural and synthetic products are in the development of new drugs, especially anti-infectives (see Review: F. von Nussbaum, M. Brands, B. Hinzen, S. Weigand, D. Angew.Chem.Int.Ed.Engl.2006,45,5072-5129; D.Obrecht,J.A.Robinson,F.Bernardini,C.Bisang,S.J.DeMarco,K.Moehle,F.O.Gombert,Curr.Med.Chem.2009 , 16,42-65), as anticancer drugs and in other therapeutic areas (C.E.Ballard, H.Yu, B.Wang, Curr.Med.Chem.2002,9, 471-498; F.Sarabia, S.Chammaa , A.S.Ruiz, L.M.Ortiz, F.J.Herrera, Curr.Med.Chem.2004, 11, 1309-1332) play a key role. They often show significant biological activity, and many macrocycles or their derivatives have been successfully developed as drugs (L.A.Wessjohann, E.Ruijter, D.Garcia-Rivera, W.Brandt, Mol.Divers. 2005,9,171 -186; D.J. Newman, G.M. Gragg, K.M. Snader, J. Nat. Prod. 2003, 66, 1022-...
