  With the purpose of obtaining more potent and selective gastric prokinetic than metoclopramide (1), a new series of N-[(2-morpholinyl)alkyl]benzamides (17-52) were synthesized and their gastric prokinetic activity was evaluated by determining effects on the gastric emptying of phenol red semisolid meal and of resin pellets solid meal in rats and mice. The morpholinyl moiety was newly designed after

  Conformationally restricted, spatially defined 12-30 membered macrocyclic ring systems of type (I) are constituted by three distinct building blocks: an aromatic template a, a conformation modulator b and a spacer moiety c as detailed in the description and the claims. Macrocycles of type (I) are readily manufactured by parallel synthesis or combinatorial chemistry. They are designed to interact with specific biological targets. In particular, they show agonistic or antagonistic activity on the motilin receptor (MR receptor), on the serotonin receptor of subtype 5-HT2B (5-HT2B receptor), and on the prostaglandin F2 • receptor (FP receptor). They are thus potentially useful for the treatment of hypomotility disorders of the gastrointestinal tract such as diabetic gastroparesis and constipation type irritable bowl syndrome; of CNS related diseases like migraine, schizophrenia, psychosis or depression; of ocular hypertension such as associated with glaucoma and preterm labour.

  构象受限、空间定义的12-30元大环环系统(I型)由三个不同的构建模块组成：芳香模板a、构象调节剂b和间隔基团c，详细描述在说明书和专利要求中。I型大环可通过并行合成或组合化学方法轻松制备。它们设计用于与特定生物靶点相互作用。特别是，它们在胃动素受体(MR受体)、5-羟色胺受体亚型5-HT2B(5-HT2B受体)和前列腺素F2•受体(FP受体)上显示激动或拮抗活性。因此，它们潜在用于治疗胃肠道低动力障碍，如糖尿病性胃轻瘫和便秘型肠易激综合征；中枢神经系统相关疾病，如偏头痛、精神分裂症、精神病或抑郁症；眼压增高，如青光眼和早产。

  Conformationally restricted, spatially defined 12-30 membered macrocyclic ring systems of formulae Ia and Ib are constituted by three distinct molecular parts: Template A, conformation Modulator B and Bridge C. These macrocycles Ia and Ib are readily manufactured by parallel synthesis or combinatorial chemistry in solution or on solid phase. They are designed to interact with a variety of specific biological target classes, examples being the agonistic or antagonistic activity on G-protein coupled receptors (GPCRs), ion channels and signal transduction pathways. In particular, these macrocycles act as antagonists of the motilin receptor, the FP receptor and the purinergic receptors P2Y 1 , as modulators of the serotonin receptor of subtype 5-HT 2B , as blockers of the voltage-gated potassium channel K v 1.3 and as inhibitors of the β-catenin-dependent “canonical” Wnt pathway. Thus they are showing great potential as medicaments for a variety of diseases.
