Abstract
Description
[0001] New compound combination of acetaminophen without hepatic side effects Technical field
[0002] The present invention relates to a new compound combination of paracetamol (Acetaminophen, APAP) without hepatic effects, in particular to a combination of paraacetaminophen and its ability to inhibit cytochrome P450 2E1 (CYP2E1) enzyme activity. A new compound of acetaminophen, which is a safe and pharmaceutically acceptable common excipient or any combination thereof, to reduce side effects such as liver toxicity caused by acetaminophen. Background technique
[0003] Acetaminophen, also known as paracetamol or N-acetyl-para-aminophenol, APAP for short, is the most commonly used antipyretic analgesic on the market, and many people often use APAP every year Cases of inappropriate poisoning or suicide have occurred. Liver damage caused by APAP is the most important factor causing severe illness and death. Many clinical experiences have proved that the hepatotoxicity of APAP can be prevented. Early diagnosis and real-time administration of the antidote N-acetylcysteine (NAC for short) can effectively prevent the occurrence of hepatotoxicity.
[0004] Early detection of acetaminophen overdose is warranted because the best prognosis is achieved when the antidote is administered within 8 hours of intoxication. The early signs of drug poisoning include physical discomfort, nausea and vomiting, but in some patients, the blood concentration of acetaminophen has reached the toxic level and the liver function is also obviously abnormal, and there are still no symptoms in the early stage (the first stage), the signs of liver toxicity Such as abdominal pain, persistent vomiting, jaundice, right upper quadrant pain, etc., will become more obvious 24 to 48 hours after a large amount of intake (the second stage). Serum transaminase usually begins to rise 16 hours after taking the drug, and clinical symptoms begin to appear. The third phase begins to appear about 3-4 days after taking the drug, at which time the degree of liver damage and prognosis can be predicted. Symptoms of liver toxicity can range from mild symptoms with elevated liver function values (AST > 1,000IU / L) to severe fulminant hepatitis with metabolic acidosis, jaundice, hypoglycemia, AST > 10,000IU / L, coagulation abnormalities and hepatic encephalopathy. The fourth stage can cause oliguric renal failure, which can lead to death in severe cases.
[0005] Some patients with acetaminophen poisoning have mild liver damage but severe nephrotoxicity. The main reason is that APAP is directly metabolized by cytochrome P-450s (cytochrome P450s, C VPs) on the renal tubules to cause nephrotoxicity. However, acute renal failure may also be caused by acute liver failure, primary kidney injury (FeNa > l) or hepatorenal syndrome (FeNa < 1). The calculation formula of FeNa: (Sodiumurinary ÷ Creatinineurinary) ÷ (Sodiumplasma ÷ Creatinineplasma) χ 100.
[0006] The peak blood concentration of acetaminophen can be reached within 1 to 2 hours after oral administration, most of which are metabolized from the liver, and more than 90% are combined with glucuronide and sulfate to form non-toxic metabolites. Only less than 5% are metabolized by different CYPs, including: CYP2E1, CYP1A2 and CYP3A4, among which CYP2E1 and CYP1A2 are the main metabolic enzymes. The metabolite N-acetyl-p-benzoquinoneimine, or NAPQI (as shown in Figure 1 ) produced by the metabolism of these enzymes is a highly active electrophile. Under normal circumstances, NAPQI will immediately react with intracellular glutathione to form a non-toxic thiol compound (mercaptide). When acetaminophen is used in excess, the consumption rate of glutathione in the cell is greater than the synthesis rate, and when the content of glutathione in the cell is lower than 30% of the normal level, NAPQI will bind to macromolecules or nucleotides containing cysteine in the cell, lead to liver cell damage. From the staining of cell tissue, it can be proved that before the necrosis of liver cells, NAPQI will form a covalent bond with the thiol group of cysteine in the center of the liver lobule.
[0007] For patients with liver disease, alcoholism, or taking drugs that induce liver cytochrome P450 enzyme activity, ^mouth: Carbamazepine, Ethanol, Isoniazid, Phenobarbital (possibly other barbiturates), Phenytoin, Sulfinpyrazone, Sulfonylureas ^ Rifampin, Primidone, etc. All belong to the high-risk group that will cause severe hepatotoxicity of APAP. At this time, if the patient has complications such as adult respiratory distress syndrome, cerebral edema, uncontrollable hemorrhage, infection or multiple organ failure, it is easy to cause death. Taking alcohol as an example, alcohol is mainly metabolized by CYP2E1 in the liver, and its mechanism of inducing APAP poisoning can be divided into three stages. The first stage is that alcohol and APAP compete for the receptor of CYP2E1 in the liver. At this time, the concentration of NAPQI will first The second stage is that alcohol will prolong the half-life of CYP2E1 from 7 hours to 37 hours, which will increase the content of CYP2E1 in the liver, and the concentration of NAPQI will slowly rise at this time; the third stage is that when the alcohol is withdrawn, the liver has more More CYP2E1 to metabolize acetamide Acetaminophen can significantly increase the toxic metabolites of acetaminophen and cause liver cell damage. Studies in recent years have confirmed that the use of diallyl sulfide can effectively prevent hepatotoxicity caused by acetaminophen in mice, and further found that diallyl sulfide can inhibit the activity of CYP2E1 enzymes. The protective mechanism of hepatotoxicity should be through the inhibition of acetaminophen to produce the active intermediate product NAPQI.
[0008] The liver function of rats is tested by invasive and non-invasive methods to monitor the development of liver damage and screen for liver diseases. The most commonly used methods include measuring serum aspartate aminotransferase (AST), Alanine aminotransferase (ALT) and alkaline phosphatase (alkaline phosphatase) values, and the measurement of liver cell products such as: bilirubin (bilirubin), albumin (albumin), and the use of prothrombin The prothrombin time is used to detect coagulation factors, etc.; the quantitative test of liver function is based on the concentration of substances in the serum that are almost only metabolized by the liver. Hepatic blood flow is related to the quantity of substances supplied to the liver, and conversely, the clearance of the substances depends on the ability of the liver to metabolize.
[0009] Galactose is a sugar with a high extraction ratio, 90% of which is metabolized in the liver. In the liver, galactose is produced by galactokinase through epimerization reaction ( epimerization) to convert it into Glucose-1-phosphate; the action of galactokinase is the rate-limiting step of the galactose metabolic pathway in hepatocytes. The high extraction rate of galactose makes galactose metabolism, which depends on liver blood flow and liver function, the most important way to detect liver function. At present, there is no certain rule to evaluate the residual liver function of rats. Measurement The ability to metabolize a given compound (eg, galactose) allows the inference of a rate-determining step in the metabolism in the liver, and it is possible to obtain a representative quantity of residual liver function.
[0010] The inventor of this case tested patients with chronic hepatitis, liver cirrhosis and liver cancer with the galactose single-point method, and the results showed that the galactose single-point method can accurately detect these liver diseases; the galactose single-point method has been successfully applied to the exclusion of patients with liver diseases Residual liver function from drugs such as promazine and the antibiotic cefoperazone. In addition, the galactose single-point method has been recommended as one of the methods for testing liver function in the Guidance for Industry published by the US Food and Drug Administration (FDA). It can be seen that the above-mentioned customary usage of acetaminophen still has many deficiencies, is not a good design, and needs to be improved. Contents of the invention

[0074] The improved results were also reflected in the corresponding liver tissue. After a single oral dose of 1000 mg / kg APAP was gavaged in rats, hepatotoxicity was successfully produced in vivo. Visceral tissue sections showed that the hepatocytes around the central vein showed fragmentation, obvious vacuolization, few nuclei, and even some hepatocytes had necrosis symptoms. Compared with the normal control group, the liver cells were seriously injured (as shown in Figure 2B ); In contrast, the liver structure in the rats in the normal control group was relatively normal, and the liver cells were intact and arranged neatly without vacuoles (as shown in Figure 2A); while mannitol, menthol, sucralose The liver tissue section results of the rats in the liver protection test group showed that the liver cells were relatively complete, with obvious nuclei and fewer vacuoles (as shown in Figure 2C, D, F, G, H), showing mannitol, menthol, trichloro The liver tissue of rats in the sucrose and other liver protection test group was closer to the liver tissue of normal rats, and the combination of mannitol and sucralose had the best protective effect, and it was positively correlated with the dose. The higher the dose, the better the protective effect.
[0075] 3. Measurement of Residual Liver Function
[0076] As shown in Table 1, the galactose single-point method (GSP) value of rats in the normal control group and the APAP liver toxicity group had a highly significant difference (the GSP value of the normal control group rats was 289±38 mg / L; The GSP value of the rats in the toxicity group was 848±123 mg / L,;? < 0.005), in addition, the GSP values of the rats in the liver protection test groups such as dicalcium hydrogenate, mannitol, menthol and sucralose were respectively 444±60 mg / L, 253±29 mg / L, 289±20 mg / L, 218±31 mg / L, compared with APAP liver toxicity group, mannitol, menthol and sucralose and other liver protection test group The GSP values of the rats were significantly different from those of the APAP hepatotoxicity group rats (;? < 0.005); the GSP values of the hepatotoxic rats were significantly increased when APAP was administered alone; however, mannitol, menthol and Rats in the liver protection test group with excipients such as sucralose can resist this change.

[0078] Screening for inhibitors of cytochrome P450 2E1 (CYP2E1) - rat liver microsomes versus human liver microsomes. Materials and Methods
[0079] 1. Test material
[0080] In this example, microsomes prepared from the livers of rats and human species were used for in vitro screening of CYP2E1 inhibitors. Cytochrome P450 2E1 (CYP2E1) inhibitors were screened for 55 common and safe edible excipients, and the large An effective inhibitor of CYP2E1 in mouse or human liver; the screening principle of the CYP2E1 inhibitor is: use the reaction of CYP2E1 in microsomes prepared from the liver of the species with its specific substrate Chlorzoxazone (CZX), add the test sample to act, and then detect CYP2E1 Metabolite Standard 6-OH-CZX ( 6 _Hydroxy-Chlorzoxazone), and based on the 6-OH-CZX production of the control group (control), the CYP 2E1 inhibition rate of the test sample was calculated.
[0081] Each test sample was dissolved in 10% methanol (methanol) or secondary water to test the effect of different concentrations of excipients (66uM, 33uM, 16.5uM; 0.167%, 0.08%, 0.042%, w / v) on CYP2E1 Inhibition rate, the results of the tested excipients are listed in Table 2.
[0082] In this example, the agents required for screening cytochrome CYP2E1 inhibitors using rat liver or human liver microsomes are as follows:
[0083] (1) CYP2E1: 100 mM potassium phosphate ( H 7.4) contains 10 mg / mL P450 protein concentration.
[0084] (2) Control Protein: 10 mg / mL P450 Protein dissolved in 100 mM Potassium Phosphate (pH 7.4).
[0085] (3) Buffer Solution: 0.5 M Potassium Phosphate (pH 7.4).
[0086] (4) Stop Solution: ice-acetonitrile.
[0087] (5) Cofactors: Contains 100 mM NADP+ and 10 mM Glucose 6-Phosphate.
[0088] (6) Glucose 6-Phosphate Dehydrogenase: 2000 units / ml dissolved in sterile water.
[0089] (7) Chlorzoxazone: Substrate, 16 mM Chlorzoxazone dissolved in 10% methanol.
[0090] (8) DDTC (Diethyldithiocarbamic acid): CYP2E1 selective inhibitor (positive control group), 20 mM DDTC dissolved in 10% methanol (methanol).
[0091] (9) NADPH-regenerating System: Add 530 uL Cofactors, 40 uL G6PDH (Glucose 6-Phosphate Dehydrogenase Solution) and 100 uL Control Protein to 3.42 mL.
[0092] 2. Screening of Cytochrome P450 2E1 (CYP2E1) Inhibitors
[0093] The protocol for screening cytochrome CYP2E1 inhibitors using rat liver or human liver microsomes is as follows: (1) 0.1M phosphate buffer (pH 7.4) containing 0.5 mg / mL rat liver or human liver microsomes, 5 mM MgCl in a water bath at 4°C 2 Let stand for 15 minutes;
[0094] (2) At this time, the experimental group was added with cytochrome P4 5 0 2E1 Reaction matrix drug 16 mM Chlorzoxazone and the compound to be screened; the control group was replaced by methanol: sterile water = 1: 1; the positive control group was replaced by DDTC;
[0095] (3) Finally, add coenzyme 1 mM NADP+, 10 mM G6P and 2 IU G6PD. The reaction solution was transferred to a 37°C water bath for pre-incubation for 1 minute, and the reaction time for the activity test experiment was 30 minutes;
[0096] (4) After the reaction, stop the reaction with 500 acetonitrile, let the sample stand for 1 minute, add the internal standard (5 ug / mL 4-hydroxy-tobutamide), centrifuge and take 20 uL of the supernatant, and use methanol: sterile water as a For ten-fold dilution, take 5 uL of the returned solution and inject it into the LC / MS / MS system for analysis;
[0097] (5) Result analysis: After converting the signal value measured by LC / MS / MS into the production amount (pmol) of CYP2E1 metabolite standard 6-Hydroxy-Chlorzoxazone, the CYP 2E1 inhibition rate of the control group is based on the control group is 0%, the CYP 2E1 inhibition rate of each positive control group and test group is calculated with the following formula: Experimental group 6 «OH« CZ3 production
[0098] CYP2I1 inhibition rate (%) [ 1 - ,,,,,,; j 100%
