Description

Non-peptide micromolecular compound is used as MC4R activators and its specific mutants medicine companion The application of companion
Technical field
The present invention relates to medicine preparation and applied technical field, and in particular to non-peptide micromolecular compound swashs as MC4R Dynamic agent and its application of specific mutants medicine companion.Described non-peptide micromolecular Compound nomenclature is BMS-470539, profit The application for preparing MC4R activators and special MC4R mutant medicine companion is used as with BMS-470539.
Background technology
Melanocortin receptor family includes 5 various physiological functions g protein coupled receptors (melanocortin receptor 1-5)1.It is black Melanocortin receptor -1 mainly acts on coloring and the anti-inflammatory of melanocyte, the life of the main function of melanocortin receptor -2 steroids Into melanocortin receptor -3 mainly acts on acquiring rate for food and nutrient distribution, the mainly regulation food intake of melanocortin receptor -4 And energy adjustment, melanocortin receptor -5 acts on outer secretion, particularly cortex glandular secretion2-7.In recent years, adult's obesity rates Rapid growth turn into influence worldwide in human health major issue.Evidence suggests melanocortin receptor -4 (Melanocortin-4receptor, MC4R) knock-out mice and the MC4R mutation mankind show early stage property obesity and with appetite Cross Sheng, hyperglycaemia and Hyperinsulinemia8-10.In addition, human genetics research shows MC4R code areas mutation stands most The single gene mutation frequently occurred leads obesogenous case11-14.Based on external functional study, MC4R mutant is divided into five classes: The first kind is null mutation acceptor;Equations of The Second Kind is cell membrane localization defect acceptor;3rd class is the affine defect acceptor of part;4th Class is signal activation defect acceptor;5th class is function burst-normal acceptor15
Most of nonactive MC4R mutant have a different degrees of cell membrane localization defect, ligand affinity defect, CAMP signals or pERK1/2 signal defects.Therefore, how to save these functional defects of MC4R mutant turns into treatment obesity Study hotspot.Such as heat shock protein A subunit can instruct MC4R correctly to fold as molecular chaperones can not be correct so as to save those The mutant of folding16.Also medicine companion PBA17, small molecule agonist THIQ18, small molecular antagonists ML00025376419All There is a certain degree of gene therapy to act on.But these molecules or medicine companion are mutated just for some special MC4R defects Body, therefore, it is necessary to the medicine companion for saving MC4R defect mutant further be excavated, for the new personalized antiadipositas drug of exploitation Thing lays the foundation.
Non-peptide micromolecular compound BMS-470539 chemical name is 1- [1- (3- methyl-L- histidyl--O- first Base-D- tyrosyls) -4- phenyl -4- piperidyls] -1- butanone, molecular weight is 559.697, the compound earliest be for MC1R by The activator of body exploitation16.Identical part can be combined based on MC4R and MC1R, and activate similar signal path.Prompting can be with For BMS-470539 carry out its as the pharmacological property research of the new activators of MC4R and its as medicine chaperone in itself Functional study to being saved MC4R mutant20
The content of the invention
It is an object of the invention to provide a kind of non-peptide micromolecular compound, numbering is BMS-470539 as melanocortin The application of acceptor -4 (abbreviation MC4R) activator.
It is BMS-470539 as preparing special MC4R mutant medicine it is a further object to provide one kind numbering The application of thing companion.
The chemical name of above-mentioned BMS-470539 compounds is 1- [1- (3- methyl-L- histidyl-s-O- methyl Ds-junket ammonia Acyl) -4- phenyl -4- piperidyls] -1- butanone, its chemical structural formula is as shown in figure 1, its molecular weight is 559.697.
In order to screen the active drug for saving MC4R defect mutant, applicant is to non-peptide micromolecular compound BMS- 470539 are studied.Applicant have studied BMS-470539 to the wild receptor actings of MC4R first, find its energy and MC4R Specifically bind and activate signal path downstream.Then, to develop its redemption effect to MC4R mutant, applicant selects 10 MC4R Equations of The Second Kind mutant (N62S, I69R, P78L, C84R, G98R, Y157S, M161T, W174C, P260Q and C271Y), 6 MC4R the 3rd class mutant (G55V, Δ 88-92, I102T, L106P, D126Y and A219V) and 4 MC4R The 4th class mutant (D90N, S136F, A175T and C326R) carried out related drugs save targeting screening test.It was found that BMS-470539 can the specific signal transduction functionality for saving some of which defect mutant.
Specifically, the present invention is achieved through the following technical solutions:
Applicant is tested by ligand affinity, the activation of cAMP and pERK1/2 signaling molecules detection, finds BMS- 470539 have high-affinity (as shown in Figure 2 and Table 1) with MC4R, and BMS-470539 also induces MC4R in dose-dependent form Signaling molecule cAMP (as shown in Figure 3 and Table 1) is produced, and induces MC4R to produce high-caliber pERK1/2 (as shown in Figure 4,5). So as to find that BMS-470539 is MC4R activator.
Applicant has found that BMS-470539 can preferably recover the class mutant of MC4R bis- by the detection to cAMP signal activations A175T, C326R in middle N62S, C84R, M161T, P260Q, G55V, I102T, L106P in the mutation of three classes, and the mutation of four classes Produce the ability of cAMP signaling molecules (as shown in Fig. 6,7,8 and table 2,3).
Applicant has found that BMS-470539 can preferably recover three classes mutation G55V by the WB detections to pERK1/2 albumen, Δ 88-92, I102T, L106P, D126Y, A219V, and four class mutant S136F, A175T, C326R produce pERK1/2 letters Number molecule ability (as Fig. 9,10 and table 3 shown in).
