Abstract
The invention relates to the field of organic synthesis and medicinal chemistry and particularly discloses an O-(benzimidazolyl) ethyl derivative of cleistanone, a preparation method and an application thereof in preparation of a medicine for resisting acute renal failure. A novel O-(benzimidazolyl) ethyl derivative of cleistanone is synthesized and the preparation method is disclosed. The pharmacological experiment shows that the O-(benzimidazolyl) ethyl derivative of cleistanone has the effect of resisting the acute renal failure and has a value for developing the medicine to resist the acute renal failure.
Description
Technical field
The present invention relates to organic synthesis and medicinal chemistry art, be specifically related to Cleistanthus sumafranus (Miq) Muell-Arg-C. Saichikii Merr wood ketone Cleistanone derivant, preparation method and its usage.
Background technology
Acute renal failure (Acute Renal Failure, ARF) be the clinical syndrome caused by many reasons, be found in clinical departments patient, sickness rate is high and often have serious consequences, its feature is that (a few hours are to a couple of days) renal function sharply declines in a short time, clinical manifestation is acute oliguria (urine volume <400mLPd) or anuria (urine volume <100mLPd), in body, nitrogen matter metabolite is discharged and is produced obstacle, there is azotemia rapidly, water and electrolyte, acid base imbalance, and cause each system corresponding function imbalance of whole body.The principal element of acute renal failure is caused to be the sharply minimizing of renal blood flow, and the oxidative stress caused due to nephridial tissue ischemia and cell injury, finally cause the deterioration of renal tissue structural damage and function.There is no the generally acknowledged effective medicine for the treatment of acute renal failure clinically at present, only by correcting water-electrolyte balance, correcting the symptomatic treatment measures such as acidosis and improving symptom, the later stage also needs to maintain body function by hemodialysis.Improving kidney perfusion obstacle and alleviating in Renal tissues damage and have the clinical medicine of obvious curative effects rare.
From natural product, find compound or lead compound and carry out structural modification and obtain its derivant, thus the potential drug obtaining high-efficiency low-toxicity there is important value most.
The compound Cleistanthus sumafranus (Miq) Muell-Arg-C. Saichikii Merr wood ketone Cleistanone that the present invention relates to is one and within 2011, delivers (Van Trinh ThiThanh et al., 2011.Cleistanone:A Triterpenoid from Cleistanthus indochinensis witha New Carbon Skeleton.
volume2011, Issue22,pages 4108 – 4111, August 2011) compound, we have carried out structural modification to compound Cleistanthus sumafranus (Miq) Muell-Arg-C. Saichikii Merr wood ketone Cleistanone, obtain a new Cleistanthus sumafranus (Miq) Muell-Arg-C. Saichikii Merr wood ketone Cleistanone derivant, and its anti-acute renal failure activity is evaluated, it is active that it has anti-acute renal failure.
Summary of the invention
The invention discloses a Cleistanthus sumafranus (Miq) Muell-Arg-C. Saichikii Merr wood ketone Cleistanone derivant, its structure is:
Cleistanthus sumafranus (Miq) Muell-Arg-C. Saichikii Merr wood ketone Cleistanone derivant (III) of the present invention is by method preparation below:
(1) Cleistanthus sumafranus (Miq) Muell-Arg-C. Saichikii Merr wood ketone Cleistanone (I) and glycol dibromide are obtained by reacting the O-bromoethyl derivant (II) of Cleistanthus sumafranus (Miq) Muell-Arg-C. Saichikii Merr wood ketone Cleistanone;
(2) the O-bromoethyl derivant (II) of Cleistanthus sumafranus (Miq) Muell-Arg-C. Saichikii Merr wood ketone Cleistanone obtains Cleistanthus sumafranus (Miq) Muell-Arg-C. Saichikii Merr wood ketone Cleistanone derivant (III) with benzimidazole generation substitution reaction.
The preparation method of further Cleistanthus sumafranus (Miq) Muell-Arg-C. Saichikii Merr wood ketone Cleistanone derivant (III) is:
(1) 440mg compound Cleistanthus sumafranus (Miq) Muell-Arg-C. Saichikii Merr wood ketone Cleistanone (I) is dissolved in 10mL benzene, in solution, adds the tetrabutyl ammonium bromide of 0.04g, the glycol dibromide of 3.760g and 50% sodium hydroxide solution of 6mL; Mixture stirs 24h at 25 degrees Celsius; After 24h, reactant liquor is poured in frozen water, use dichloromethane extraction twice immediately, merge organic phase solution; Then use water and saturated common salt water washing 3 times successively to organic phase solution, then use anhydrous sodium sulfate drying, last concentrating under reduced pressure is removed solvent and is obtained product crude product; Product crude product purification by silica gel column chromatography, mobile phase is: petroleum ether/acetone=100:1, v/v, collects the yellow yellow solid concentrating elution band namely to obtain the O-bromoethyl derivant (II) of Cleistanthus sumafranus (Miq) Muell-Arg-C. Saichikii Merr wood ketone Cleistanone.
(2) the O-bromoethyl derivant of the Cleistanthus sumafranus (Miq) Muell-Arg-C. Saichikii Merr of 273mg wood ketone Cleistanone is dissolved in the middle of 15mL acetonitrile, adds the Anhydrous potassium carbonate of 345mg wherein, the potassium iodide of 84mg and the benzimidazole of 1180mg, mixture reflux 5h; After reaction terminates, reactant liquor is poured in frozen water, with equivalent dichloromethane extraction three times, merge organic facies; Organic facies after merging with water and saturated common salt water washing successively, then use anhydrous sodium sulfate drying, concentrating under reduced pressure is removed solvent and is obtained product crude product; Product crude product purification by silica gel column chromatography, mobile phase is: petroleum ether/acetone=100:1.5, v/v, collects the brown solid that namely brown concentrated elution band obtains Cleistanthus sumafranus (Miq) Muell-Arg-C. Saichikii Merr wood ketone Cleistanone derivant (III).

Embodiment 4 compound III is to the therapeutical effect of acute renal failure rat
(1) experimental technique
Intramuscular injection glycerol is adopted to cause Acute Renal Failure Rats animal model.Select the healthy male SD rat 30 of 180 ~ 220g, be divided into 3 groups at random: sham operated rats (intramuscular injection normal saline); Model group (intramuscular injection glycerol); Compound III group (compound III 0.6mg/Kg, intramuscular injection glycerol), each group rat tail vein injection saline or compound III immediately after glycerol modeling, be administered once after 12 and 24 hours again.
(2) observation index
Rat last is put into metabolic cage and is collected twenty-four-hour urine after giving compound III or normal saline, stay latter 6 hours of urine with 4% chloral hydrate intraperitoneal injection of anesthesia, adopt laser Doppler flowmetry to measure after modeling and bilateral renal blood flow after treatment, average as single animal renal blood flow; Get blood and prepare serum, measure blood BUN and Cre (all by the operation of test kit description).
(3) experimental result
1. compound III can increase acute renal failure Mouse Kidney blood flow
Table 1 compound III is on the impact of acute renal failure Mouse Kidney blood flow
* P<0.05vs acute renal failure model group
2. compound III is to the protective effect of acute renal failure Mouse Kidney function tool
Acute renal failure rat intravenous injection normal saline is after 24 hours, and serum BUN and Cre is in table 2.Acute renal failure model group, apparently higher than sham operated rats, illustrates that model group animal renal function injury is serious.Compound III can improve the renal function (P<0.05) of acute renal failure rat.In table 2.
The each rats in test groups renal function index of table 2 compares
* P<0.05vs acute renal failure model group
Conclusion: compound III can protect the function of kidney, can be used for preparing anti-acute renal failure medicine.
The preparation of embodiment 5 compound III tablet involved in the present invention
Get the one in the middle of 20 g of compound III or its pharmaceutically acceptable salt, add the customary adjuvant 180 grams preparing tablet, mixing, conventional tablet presses makes 1000.
The preparation of embodiment 6 compound III capsule involved in the present invention
Get the one in the middle of 20 g of compound III or its pharmaceutically acceptable salt, add prepare capsule customary adjuvant as starch 180 grams, mixing, encapsulatedly makes 1000.
