Abstract
The invention relates to a C-aryl glucoside derivative indicated by a general formula I, as well as a usage and a composition thereof. The C-aryl glucoside derivative has a good effect in inhibiting SGLT. The composition can be separately used or used together with other antidiabetic medicine or other therapeutic agent and can be used for preventing or curing diabetes and other relevant diseases.
Description
Technical field
The invention belongs to field of pharmacology, relate to class C-aryl glucoside derivative or its isomer, racemic modification, precursor or a pharmacy acceptable salt, and their purposes and composition.
Background technology
According to the data that the World Health Organization announces, nearly 1.5 hundred million people in the whole world suffer from diabetes.Type i diabetes (IDDM) and type ii diabetes (NIDDM) are two types the most basic in the diabetes, the former pathogenic characteristic is that pancreas can not excreting insulin, and the latter's pathogenic characteristic is the Regular Insulin relative deficiency due to the slow and insulin resistant of insulin secretion.Type ii diabetes is the most general one type, and nearly 90% diabetic subject belongs to this type.Hyperglycemia is considered to form the primary hazard factor of diabetic complication.The major complications of diabetes comprises retinal diseases, cardiovascular disorder, kidney disease, DPN, ulcer and foot pathology etc.
Type i diabetes generally adopts insulinize, though type ii diabetes can and be taken exercise and regulate by diet, pharmacological agent is normally requisite.The treatment type ii diabetes is except using Regular Insulin at present, also has some other alternative antidiabetic medicine, such as biguanides (reducing glycogen output and increase susceptibility), sulfonylurea and meglitinide (stimulating the generation of Regular Insulin), alpha-glucosidase inhibitor (reduction postprandial blood sugar) and thiazolidinediones (increasing susceptibility) to Regular Insulin to Regular Insulin.These Side effects of pharmaceutical drugs mainly comprise lactic acidosis (biguanides), hypoglycemia (sulfonylurea), oedema and weight increase (thiazolidinediones).Therefore wish to develop that make new advances, safe and orally active antidiabetic medicine,, and avoid occurring the relevant potential side effect of these medicines with additional existing therapy.
Kidney glucose transport system is a very promising target spot that can be used for therapeutic intervention diabetes and metabolism disorder thereof.The glucose transport of cell is finished by the glucose transporter (GLUTs) and the sodium dependent glucose transporter (SGLT) of facilitation diffusion.SGLT1 mainly is distributed in the brush border of small intestine, and SGLT2 is distributed in kidney cortex proximal tubule.Glucose heavily absorbing in kidney 90% betides in the epithelial cell of initial S1 section of kidney cortex proximal tubule, and SGLT2 is likely and is responsible for this re-absorbed main translocator.Nearest research prompting, thus the drainage that suppresses the SGLT increase glucose in urine of kidney is effective means (Arakawa K etc., Br J Pharmacol 132:578-86,2001 of treatment hyperglycemia; OkuA etc., Diabetes48:1794-1800,1999).Discover that thereby the SGLT2 transgenation that occurs in familial kidney glucose in urine patient causes sugar to be discharged from urine and makes glucose level normalizing, and the disorderly symptom relevant with other of renal function disappeared also.Therefore, can suppress SGLT particularly the compound of SGLT2 be very promising candidate antidiabetic medicine.
Although had at present at the compound that suppresses SGLT, yet also there are defectives such as activity is on the low side, effect is not enough in these compounds, so this area awaits to develop more effective compound.
Summary of the invention
The object of the present invention is to provide a class for suppressing SGLT very effective C-aryl glucoside derivative or its isomer, racemic modification, precursor or pharmacy acceptable salt, their purposes and pharmaceutical composition.

14C] pyranoside picked-up carrying out quantitative analysis.Sodium dependency pyranoside intake is with containing the sodium damping fluid and handles the intake obtain and deduct no sodium damping fluid and handle the difference of the intake that obtains (three answer the mean values in holes).
Table 1 compound external activity test result
Compound number | SGLT2 IC 50(nM) | SGLT1 IC 50(nM) | Selectivity (IC 50-SGLT1/IC 50-SGLT2) |
DAPAGLIFLOZIN (BMS-512148) | 7 | 885 | 126 |
Compd A | 2 | 614 | 307 |
Annotate: the data of the DAPAGLIFLOZIN (BMS-512148) that ADA (ADA) annual meeting in 2007 is announced are SGLT2 IC50=1.0nM, SGLT1 IC50=1600nM, and compound is 1600 to the selectivity of SGLT2 and SGLT1.For activity that can more objective compound of reaction, the inventor has added in test 25% human plasma (seeing test portion for details), with the intravital environment of anthropomorphic dummy.
Wherein, Compound D APAGLIFLOZIN (BMS-512148, CAS number: 461432-26-8) be a kind of C-aryl glucoside SGLT2 inhibitor.Its structure and relevant information are as follows:
Therefore as seen, in the test system that has added 25% human plasma, the external activity of the compd A of the present invention and selectivity of SGLT2 and SGLT1 significantly is better than reference compound DAPAGLIFLOZIN (BMS-512148) has the effect of good inhibition Na-dependent glucose transporter (SGLT2).
The glucose in urine of embodiment 4 compounds is discharged test
1. the rat glucose in urine of compound is discharged test
Irritate stomach by the compound (being respectively DAPAGLIFLOZIN (BMS-512148) and compd A) of body weight 1mg/kg amount after the fasting overnight of healthy male SD rat (5 every group), after the administration 1 hour, the glucose solution that orally give body weight 2g/kg measures.Urine is collected to detect in the urine glucose concn and to write down the urine amount in 4 hours and 24 hours after administration.Multiply by the uri-meter calculation with glucose in urine concentration and obtain the glucose in urine output.
