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.
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

1.3 and as inhibitors of the β-catenin-dependent “canonical” Wnt pathway. Thus they are showing great potential as medicaments for a variety of diseases.

Method for producing liposomes in a composition for skin permeation are provided. A composition that includes water, skin lipids, butters having linoleic acid and linolenic acid, Pracaxi oil, Plukenetia Volubilis seed oil, and phospholipids is provided. The composition is dispersed in a vessel using a high shear homogenizer. Negative pressure is created in the vessel such that liposomes of 5-20 microns are produced thereby providing for increased skin permeation of active ingredients added to the composition.

A composition to be used as a permeation enhancer is provided. The composition may be added to topical cosmetics or pharmaceutical formulations that are topically applied. The composition comprises about 0.05-5% w/w of one or more phospholipids, 1-20% w/w of one or more oils having essential fatty acids, behenic acid, and oleic acid, 0.1-3% w/w of one or more skin lipids, and 1-10% w/w of a butter having linoleic acid and linolenic acid. One of the oils used in the composition is Pracaxi oil.
