Definitions

  • the present invention relates to novel non-peptide GLP-1 agonists, pharmaceutical compositions comprising them, use of the non-peptide GLP-1 agonists for the preparation of pharmaceutical compositions and methods for the treatment and/or prevention of disorders and diseases wherein an activation of the human GLP-1 receptor is beneficial, especially metabolic disorders such as IGT (impaired glucose tolerance), Type 1 diabetes, Type 2 diabetes and obesity.
  • IGT abnormal glucose tolerance
  • GLP-1 (glucagon like peptide-1 ) is a 30 amino acid long peptide hormone secreted by the L- cells in the intestine.
  • GLP-1 consists of two native forms, GLP-1 (7-36) and GLP-1 (7-37), of the following amino acid sequences:
  • X is NH 2 for GLP-1 (7-36) and Gly for GLP-1 (7-37).
  • GLP-1 is a so-called incretin and its primary mechanisms of actions are to:
  • GLP-1 a very efficient blood glucose lowering agent (1 ).
  • the very efficient blood glucose lowering as well as the glucose dependency of its action makes it an ideal candidate for the treatment of Type 2 diabetes (2-10).
  • GLP-1 offers something that no other existing drug or drug candidate can provide: very efficient blood glucose lowering, even in SU (sulphonylurea)-failures (6), without the risk of serious hypoglycaemia.
  • GLP-1 has also been shown to increase the rate of insulin biosynthesis (12,13) and restore the ability of the ⁇ -cells to respond rapidly to rising plasma glucose in terms of first phase insulin release in rats (14).
  • GLP-1 would be expected to be able to prevent or delay the progression from IGT to full blown Type 2 diabetes.
  • Patients treated with GLP-1 compared to eg metformin or sulphonylureas, will be better managed and may as a result thereof have a much later transfer to insulin requiring therapy.
  • GLP-1 compounds have been shown to stimulate growth and proliferation of ⁇ -cells (15-17), thereby also supporting use of GLP-1 compounds and GLP-1 agonists for increasing the number of ⁇ -cells in a patient in vivo.
  • Type 2 diabetes patients may be an impaired incretin function (18,19).
  • GIP Global Inhibitory Polypeptide (19,20).
  • GIP Gastric Inhibitory Polypeptide
  • GLP-1 The ability of GLP-1 to decrease appetite and energy intake is now firmly established, both in normal, lean people and in obese people (22-24). Obese subjects have been shown to have an attenuated GLP-1 release in response to meals (25,26). This may further add to the po- 5686.204-WO tential of GLP-1 as being able to decrease weight in Type 2 diabetes patients. This use of GLP-1 is described further in WO No 98/20895 to Novo Nordisk A/S and WO No 98/28414 to Eli Lilly and Company.
  • GLP-1 is rapidly metabolised by the proteolytic enzyme Dipeptidyl Peptidase-IV (27) into an inactive or perhaps even antagonistic metabolite (28), complicating the use of GLP-1 as a drug.
  • GLP-1 and analogues of GLP-1 as well as fragments thereof in the treatment of Type 1 and Type 2 diabetes and obesity are disclosed in several publications.
  • GLP-1 fragments including GLP-1 (7-37) and GLP-1 (7-36), and functional derivatives thereof for use as insulinotropic agents.
  • WO No 91/11457 to Buckley et al. discloses analogues of the active GLP-1 peptides 7-34, 7-35, 7-36, and 7-37 for use in the treatment of Type 2 diabetes
  • WO No 98/08871 to Novo Nordisk A/S discloses derivatives of GLP-1 for use in the treatment of diabetes and obesity which are especially useful as they are both metabolically stable and very potent.
  • peptides are generally not known to be orally available.
  • the GLP-1 receptor is a so-called 7 transmembrane (7TM) G-protein coupled receptor. These receptors are transmembrane proteins consisting of a N-terminal extracellular part, a transmembrane core and three extracellular and three intracellular loops. The receptors are coupled to a G-protein (consisting of three subunits) and then further to an effector system.
  • the effector system for the GLP-1 receptor is the adenylyl cyclase enzyme. Upon activation of the receptor, adenylyl cyclase catalyses the formation of the second messenger cAMP from ATP.
  • glucagon-secretin (B) family consists of the receptors for GLP-1 , glucagon, GIP, secretin, VIP, PACAP, calcitonin, PTH, CRF, GRF and a few more.
  • the (B) family is characterised by a relative large N-terminal domain of the receptor.
  • the natural ligands for these receptors are all large peptides and the binding (and consecutive activation) of the receptors by their natural ligands is believed to involve both the N-terminal domain and the transmembrane region.
  • They may be characterised by activating the human GLP-1 receptor without competing with GLP-1 for the GLP-1 binding site in a competition binding assay.
  • G-protein coupled receptors are theoretically thought to exist in different conformations: R and R * , where R is the inactive receptor conformation and R * the active.
  • R is the inactive receptor conformation
  • R * the active.
  • the most recent literature speculates that there may be one or more intermediate states (31 ).
  • the compounds according to the invention may introduce a new model in order to accommodate their characteristics.
  • this model we introduce a further receptor conformation R** which is another active receptor conformation.
  • R* would then be the conformation that GLP-1 under normal circumstances stabilises where R** is the conformation that the compounds according to the invention stabilises.
  • a model with two different active receptor conformations may also offer an explanation for why some of the compounds according to the invention when tested in the assays are partial and not full agonists because one conformation may be able to elicit partial agonism only and the other full agonism.

  • non-peptide GLP-1 agonists according to the invention may be either partial or full agonists.
  • non-peptide GLP-1 agonist is a partial agonist.
  • Such partial agonists may be less likely of causing the receptor to desensitise because they do not fully activate the receptor and therefore also do not fully activate the desensitisation signals.
  • the non-peptide partial agonists have an E max of less than 90%, preferably less than 80% and more preferred in the range of 35 to 75% of that of GLP-1.
