Abstract

Provides a bisindolylmaleimide derivative and a preparation method and application thereof. The bisindolylmaleimide derivative has a good alpha-glucosidase inhibition effect, and can be used for preventing and treating diabetes.

Description

Bisindolylmaleimide derivative and preparation method and application thereof
The technical field is as follows:
the invention relates to a bisindolylmaleimide derivative and a preparation method and application thereof.
Background art:
with the change of living habits and dietary patterns of people, the incidence of diabetes mellitus is rising year by year. Data published by the WHO in 2011 shows that about 460 million people die of diabetes-related diseases worldwide each year, with medical costs for diabetes as high as $ 4650 million. Currently, there are nearly 1.0 million diabetics and about 3.4 million people with abnormal glucose metabolism in China. Diabetes has become the third leading killer following cancer, cardiovascular disease.
Diabetes is classified into type 1 diabetes (insulin-dependent diabetes mellitus) and type 2 diabetes (non-insulin-dependent diabetes mellitus), and more than 90% of patients belong to type 2 diabetes mellitus. The type 2 diabetes patient does not need insulin treatment, can regulate and control blood sugar by diet, and is treated by medicine only when diet regulation is ineffective. Starch in food is digested into oligosaccharide of glucose molecule by oral saliva and pancreatic amylase, the alpha-glucosidase breaks the alpha-1, 4-glycosidic bond of the oligosaccharide at non-reducing end to release glucose, and the glucose is absorbed by small intestine epithelium and enters blood circulation to become blood sugar. Under physiological state, alpha-glucosidase exists in the upper, middle and lower segments of small intestine, so that the sugar is absorbed rapidly and perfectly by human body. Alpha-glucosidase inhibitors delay or slow postprandial blood glucose elevation by reversibly or competitively inhibiting the activity of alpha-glucosidase at the brush border of the small intestine. In addition, after the alpha-glucosidase inhibitor drugs are taken in the fasting state (when the lower small intestine has no food ingredients), chyme such as carbohydrate, fat, protein and the like in the intestines enters the far end of the ileum; the part is the position with the most abundant storage of the small intestine glucagon-like peptide 21(GLP21), and can stimulate the increase of GLP21 secretion and the release of insulin, thereby reducing the postprandial blood sugar concentration. Therefore, alpha-glucosidase inhibitors (AGIs) are a class of oral hypoglycemic drugs that delay the absorption of carbohydrates in the intestinal tract to achieve the purpose of treating diabetes.
At present, the clinically applied alpha-glucosidase inhibitor drugs are mainly: after the acarbose, the voglibose and the miglitol are taken, the acarbose, the voglibose and the miglitol directly reach the large intestine without decomposing carbohydrate, and adverse reactions such as abdominal discomfort, flatulence, exhaust and the like can occur. Therefore, new alpha-glucosidase inhibitor drugs need to be found.
Diabetic nephropathy (DKD) is one of the most common serious microvascular complications of diabetes, occurs at about 30% -40% of Diabetic patients, has become the first cause of End Stage Renal Disease (ESRD), and is also the leading cause of mortality of diabetes. At present, although some progress is made in the research aspect of anti-DKD medicines, the existing clinical treatment means such as controlling blood pressure, blood sugar, blood fat, anti-inflammation and the like can only delay the progress of DKD to renal failure but can not reverse or prevent the disease development; meanwhile, the problems of uncertain curative effect, large toxic and side effects and the like (Curr Diabetes Rev 2005; 1: 281-.
The invention content is as follows:
the bisindolylmaleimide derivatives are widely concerned due to structural diversity and good biological activity, and the inventor is focused on the drug development of the bisindolylmaleimide derivatives, and unexpectedly finds that the compounds have alpha-glucosidase inhibitory activity and anti-diabetic effect.
Thus, the present inventors provide a compound of formula a, a pharmaceutically acceptable salt or prodrug thereof:

[ example 2 ] Activity assay
1. Alpha-glucosidase inhibitory Activity test
(1) Test method
The alpha-glucosidase inhibitory activity of some compounds was tested using p-nitrophenyl-alpha-D-glucopyranoside (PNPG) as substrate. PNPG is an analogue of maltose, can generate yellow p-nitrophenol after the action of alpha-glucosidase, and can be directly used for the detection of a spectrophotometer. The method comprises the following steps: first, the sample was dissolved in PBS sodium phosphate buffer (pH 6.8)Preparing 5 concentrations; then, 10. mu.L of the sample solution, 20. mu.L of the PBS solution, and 20. mu.L of a 2.5 mM-concentration glucoside solution (dissolved in a phosphate buffer solution) were added to each well of the 96-well plate, and the mixture was incubated at 37 ℃ for 5 minutes in an incubator. Alpha-glucosidase was diluted to 0.2U/mL with 0.01M PBS, 10. mu.L of each well was added to the above test solution, and after incubation at 37 ℃ for 15min in an incubator, the absorbance (OD value) at 405nm per well was measured with a microplate reader, and the inhibition (%): [ 1- (OD)Sample (I)/ODControl)]X 100%, to obtain IC50(μ M). The blank control is phosphate buffered saline solution, and the positive control is acarbose and nojirimycin.

2. In vivo antidiabetic nephropathy (DKD) assay
The in vivo anti-diabetic nephropathy (DKD) activity of compound 49 was evaluated using a classical db/db animal model of diabetic nephropathy.
Animal experiments are divided into 6 groups, each group is provided with 12 mice, the positive drug is selected from losartan, and each group adopts a subcutaneous injection administration mode. The administration was continued for 4 weeks, and the control group was given the same volume of physiological saline. The results show that lower injected doses of compound 49(1.0mg/kg/day and 2.0mg/kg/day) are able to significantly reduce 24 hour urine protein (24UPE) and Blood Urea Nitrogen (BUN) levels without significant change in the effect on fasting glucose (FBG); particularly, at the administration dose of 1.0mg/kg/day, the inhibition degree of 24UPE is up to 48.3 percent, which is better than that of the positive medicament Losartan (Losartan) (35.2 percent). The results are shown in Table 2.
