Definitions
- the present invention relates to a compound exhibiting excellent agonistic activity against melanocortin receptors, and more particularly, to a compound of Formula 1 below, a pharmaceutical composition comprising the same as an active ingredient, and uses, wherein the compound of the present invention is melanocortin It shows excellent hyperactive activity on the cortin-4 receptor, and can be particularly usefully used for prevention or treatment of obesity, diabetes, inflammation and erectile dysfunction:
- R1, R2, R3, R4 and n are as defined in the specification.
- Leptin protein is a hormone secreted by body fat cells (adipocytes), and its secretion increases with an increase in body fat content, and by regulating the functions of various neuropeptides generated in the hypothalamus, appetite, body fat It regulates various in vivo functions, including content and energy metabolism (Schwartz, et al., Nature 404, 661-671 (2000)).
- the signal transduction of appetite and weight control by leptin protein is made through the regulation of many factors downstream, the most representative of which are melanocortin, AgRP (agouti-related peptide) and neuropeptide Y. (neuropeptide Y, NPY) is a hormone.
- Alpha-MSH hormone induces various physiological responses by binding to three MCR subtypes in addition to MC4R.
- Five MCR subtypes have been identified so far.
- MC1R is mainly expressed in skin cells and is involved in melanin pigmentation (skin pigmentation)
- MC2R is mainly expressed in the adrenal gland and is mainly expressed in the production of glucocorticoid hormone. It is known to be involved and only the adrenocorticotropic hormone (ACTH) derived from POMC is its ligand.
- ACTH adrenocorticotropic hormone
- MC3R and MC4R which are mainly expressed in the central nervous system, are involved in the regulation of appetite, energy metabolism, and body fat storage efficiency, and MC5R expressed in various tissues is known to regulate exocrine function (Wikberg, et al., Pharm Res 42 (5) 393-420 (2000)).
- activation of the MC4R receptor has been proven to be a major action point in the development of anti-obesity drugs because it has the effect of effectively reducing body weight by inducing a decrease in appetite and an increase in energy metabolism (Review: Wikberg, Eur. J. Pharmacol 375, 295).
- MC4R The role of MC4R in appetite and weight control was primarily demonstrated through an agouti protein aberrant expression animal model (agouti mouse) experiment.
- agouti protein was expressed at a high concentration in the central nervous system due to genetic mutation and induces obesity by acting as an antagonist of MC4R in the hypothalamus (Yen, TT et al., FASEB J). 8, 479-488 (1994);Lu D., et al. Nature 371, 799-802 (1994)).
- AgRP agouti-related peptide
- Appetite inhibitors acting on the central nervous system are the main types of obesity treatment developed so far, and most of them are drugs that control the action of neurotransmitters. Examples include noradrenalin agents (phentermine and mazindol) and serotonergic agents fluoxetine and sibutramine.
- noradrenalin agents phentermine and mazindol
- serotonergic agents fluoxetine and sibutramine.
- the neurotransmitter modulator it exerts a wide range of effects on various physiological actions in addition to appetite suppression through numerous subtype receptors. Therefore, in the case of the modulators, there is a major disadvantage in that the selectivity for each subtype is lacking, and various side effects are accompanied by long-term administration.
- melanocortin agonists are neuropeptides, not neurotransmitters, and in MC4R gene KO mice, all other functions other than energy metabolism are normal. It has an advantage as an action point in that it can induce only a decrease.
- the receptor is a G-protein coupled receptor (GPCR), which belongs to the most successful category of new drug action points developed so far, and it is greatly distinguished from existing action points in that it is relatively easy to secure selectivity for subtype receptors. do.
- GPCR G-protein coupled receptor
