Abstract
The invention relates to the field of type 2 diabetes related medicines and specifically relates to an 11beta-HSD1 inhibitor of a cyanobipyridine tert-alcohol structure, a preparation method of the 11beta-HSD1 inhibitor and the application of the 11beta-HSD1 inhibitor in preparing type 2 diabetes medicines. A formula I is as shown in the specification, wherein R is selected from the cyano group.
Description
Technical field
The present invention relates to the pharmaceutical field of diabetes B treatment.Specifically, the present invention relates to 11 beta-HSD 1 inhibitors, its preparation method to the medicative class nitrile group-containing two pyridine tertiary alcohol structure of diabetes B tool, and the purposes in pharmacy.
Background technology
Diabetes are the lysis caused by multi-pathogenesis, have influence on the population of global 6%-7%.Expect 2025, number of patients can double again and reach 300,000,000.The most important clinical pathologic characteristic of diabetes is that plasma glucose (blood sugar) concentration increases.It is the major cause leading diabetogenic various clinical symptom that blood sugar concentration increases.Unsteered hyperglycemia causes many diabetic complications, comprises ephrosis, neuropathy, retinopathy, hypertension, cerebral ischemia and coronary heart disease etc.Therefore, the key that blood sugar is treatment and prevent diabetes and complication thereof is reduced.
11-beta-hydroxy steroid dehydrogenase type 1 (11 β-HSD1) is the Effective target site of the symptom relevant with improving other diabetes to glycemic control in the past few years confirmed.Research is determined, glucocorticoid activity does not control by means of only secretion hydrocortisone and hands over control in tissue mutually horizontally through in the cell of active Cortisol and nonactive cortisone, this mutual traffic is crossed through 11-beta-hydroxysteroid dehydrogenase, namely 11 β-HSD1 (it activates cortisone) and 11 β-HSD-2 (its deactivation hydrocortisone) complete (Sandeep TC & Walker BR, Trends Endocrinol & Metab., 2001,12,446-453).This mechanism may be important for people, several in carbenoxolone (the anti-stain of a kind of suppression 11 β-HSD1 and-2 is die young medicine) treatment at first, this treatment causes insulin sensitivity to improve, illustrate 11 β-HSD1 by reduce active glucocorticoid organize horizontal Effective Regulation insulin action (WalkerBR et al.J.Clin.Endocrinol.Metab., 1995,80,3155-3159).
Many have insulin resistance but the patient not developing into diabetes B also has development to be called the risk of the symptom of " syndrome X " or " metabolic syndrome ".Syndrome X or metabolic syndrome take insulin resistance as feature, and with abdominal obesity, hyperinsulinemia, hypertension, low high-density lipoprotein (HDL) (HDL) and high vldl (VLDL).No matter whether these patients, develop into obvious diabetes, all have the risk of the above-mentioned cardiovascular complication of the development of increase.11 beta-HSD 1 inhibitors, except having therapeutic action ten thousand to diabetes B, increase the cognition enhancing needed for lipid disorders, obesity, atherosclerosis, Alzheimer and associated conditions, hypertension, intraocular pressure, promote that wound healing and metabolic syndrome etc. all have certain treatment and prophylactic effect.
The invention discloses 11 beta-HSD 1 inhibitors of a class nitrile group-containing two pyridine tertiary alcohol structure, these compounds can be used for the medicine preparing treatment diabetes B and relative disease thereof.

Embodiment
Below in conjunction with embodiment, the present invention is further illustrated.It should be noted that, following embodiment be only for illustration of, and not for limiting the present invention.The various changes that those skilled in the art's training centre according to the present invention is made all should within the protection domain required by the application's claim.
the synthesis of embodiment 1 Compound I-1
The synthesis of step 1. compound IV
Compound II per (0.80g, 10mmol) and compound III (0.86g, 10mmol) are dissolved in 10mL benzene, reflux 1 hour under nitrogen protection, and TLC checks and finds that reaction completes.Evaporate to dryness on a rotary evaporator after reaction mixture is slightly cold, resistates column chromatography purification, obtains compound IV, white solid, ESI-MS, m/z=167 ([M+H]
+).
The synthesis of step 2. Compound I-1
Compound V-1 (2.20g; 12mmol) be dissolved in the THF of 20mL drying;-78 DEG C are cooled under nitrogen protection; 7.5mL (12mmol) n-BuLi is slowly dripped with syringe under stirring; after dropwising; reaction mixture continues stirring 1 hour at such a temperature; then slowly drip compound IV (0.83g with syringe again; the solution that THF 5mmol) being dissolved in 1mL drying makes; after dropwising; reaction mixture at room temperature stirs and spends the night, and TLC shows reaction to be completed.Reaction mixture pours in 200mL frozen water, stirs, with 50mL × 3CH
2cl
2extraction, merges extraction phase, uses salt water washing, anhydrous sodium sulfate drying.Suction filtration removing siccative, filtrate is evaporate to dryness on a rotary evaporator, and resistates uses purification by silica gel column chromatography, obtains Compound I-1, white solid, ESI-MS, m/z=343 ([M+H]
+).
embodiment 2-4
With reference to the method for embodiment 1, synthesize compound listed in Table:
embodiment 5 Compound ira vitro is to the restraining effect of 11 β-HSD1
The vitro enzyme activity of test compound is evaluated through scintillation proximity assay (SPA).The determined compound 11 β-HSD1 enzymes optimizing cortisone substrate, NADPH cofactor and structural formula (I) are made to carry out to the conversion of hydrocortisone 37 DEG C of cultivations.After incubation, the preparation of the SPA pearl applied by the a-protein with the pre-mixing of anti-hydrocortisone monoclonal antibody and nonspecific 11 β-HSD inhibitor such as 18 β-glycyrrhetinic acids adds in each hole.Mixture, 15 DEG C of vibrations, reads with the liquid scintillation counter being suitable for 96 orifice plates subsequently.Calculate relative to non-suppression control wells and suppress percentage ratio, obtain IC
50curve.Specifically, add in the hole of specifying on 96 orifice plates 40 μ L substrates (25nM in 50mM HEPES damping fluid [
3h]-cortisone+1.25mM NADPH, pH 7.4).Compound is dissolved in DMSO with 10mM, 50 times of dilutions successively in DMSO.Material 4 times of titration subsequently of dilution 7 times.In substrate, add the titrated compound of 1 μ L respectively subsequently in duplicate.For starting reaction, in each hole, add 11 β-HSD1 microsomes that 10 μ L obtain by Chinese hamster ovary celI transfection thing with the feedstock conversion producing about 10% with suitable concentration.For finally calculating suppression percentage ratio, add in a series of holes of the minimum and maximum test of expression: the one group of material not having compound or enzyme (background) containing substrate, containing substrate and enzyme without any another group material (peak signal) of compound.Plate is centrifugal to collect reactant simply under the low speed in centrifuges, with adhesive tape sealing, slowly mixes, cultivates 2 hours at 37 DEG C.After incubation, in each hole, add SPA pearl and formula (I) compound that the anti-hydrocortisone monoclonal antibody of 45 μ L suspends in advance.Plate is resealed, 15 DEG C of gentle vibrations more than 1.5 hours.Data are collected in plate base liquid scintillation counter.For controlling the suppression that anti-hydrocortisone antibody/hydrocortisone combines, will with 1.25nM [
3h-] hydrocortisone do in target substrate add in the single hole of specifying.In each such hole, add 200 μMs of compounds of 1 μ L, replace enzyme with 10 μ L damping fluids simultaneously.The suppression of any calculating is incorporated into the interference of the antibody on SPA pearl to hydrocortisone owing to compound.Test result sees the following form.
| Compound | IC 50(nM) |
| Reference compound R-1 | 18.3 |
| Compound I-1 | 11.6 |
| Compound I-2 | 12.1 |
