Pharmacodynamics · 1 件

Aminosalicylic acid is an anti-mycobacterial agent used with other anti-tuberculosis drugs (most often isoniazid) for the treatment of all forms of active tuberculosis due to susceptible strains of tubercle bacilli. The two major considerations in the clinical pharmacology of aminosalicylic acid are the prompt production of a toxic inactive metabolite under acid conditions and the short serum half life of one hour for the free drug. Aminosalicylic acid is bacteriostatic against <i>Mycobacterium tuberculosis</i> (prevents the multiplying of bacteria without destroying them). It also inhibits the onset of bacterial resistance to streptomycin and isoniazid.

Mechanism of Action · 3 件

There are two mechanisms responsible for aminosalicylic acid's bacteriostatic action against <i>Mycobacterium tuberculosis</i>. Firstly, aminosalicylic acid inhibits folic acid synthesis (without potentiation with antifolic compounds). The binding of para-aminobenzoic acid to pteridine synthetase acts as the first step in folic acid synthesis. Aminosalicylic acid binds pteridine synthetase with greater affinity than para-aminobenzoic acid, effectively inhibiting the synthesis of folic acid. As bacteria are unable to use external sources of folic acid, cell growth and multiplication slows. Secondly, aminosalicylic acid may inhibit the synthesis of the cell wall component, mycobactin, thus reducing iron uptake by <i>M. tuberculosis</i>.

The antimicrobial activity of aminosalicylic acid is highly specific, and microorganisms other than Mycobacterium tuberculosis are unaffected. Most nontuberculous mycobacteria are not inhibited by the drug.

Aminosalicyclic acid is a structural analog of paraaminobenzoic acid, and its mechanism of action appears to be very similar to that of the sulfonamides. Since the sulfonamides are ineffective against Mycobacterium tuberculosis, and aminosalicyclic is inactive against sulfonamide susceptible bacteria, it is probable that the enzymes responsible for folate biosynthesis in various microorganisms may be quite exacting in their capacity to distinguish various analogs from the true metabolite.

An N-acetylation polymorphism is described that is expressed toward arylamine carcinogens in tumor target organs of an inbred rat model. High levels ... of arylamine carcinogen N-acetyltransferase activity were observed in kidney, colon, prostate and urinary bladder cytosols derived from Fischer (F-344) inbred rats ... Significantly lower ... levels of arylamine carcinogen N-acetyltransferase activity were observed for corresponding tissue cytosols derived from Wistar-Kyoto inbred rats. Intermediate levels of arylamine carcinogen N-acetyltransferase activity significantly different from both the parental strains were observed in F1 hybrids of the parental strains, consistent with codominant expression of two alleles at a single gene locus. The arylamine substrates exhibiting the acetylator phenotype-dependent N-acetyltransferase activities included ... p-aminosalicylic acid ... Highest levels of arylamine carcinogen N-acetyltransferase were expressed consistently in colon cytosol, but expression of the N-acetylation polymorphism toward arylamine carcinogens was observed in each (kidney, colon, prostate and urinary bladder) of the tumor target organs. The expression of the N-acetylation polymorphism in tumor target organs suggests that the inbred rat model will be useful in assessing the role of acetylator phenotype in arylamine-induced cancers of the colon and prostate.

An overview is presented of a selected number of mono-aromatic derivatives and their short-term effects on hepatic fatty acid biosynthesis. The cmpd discussed in this paper are o-hydroxybenzoate ... m-hydroxybenzoate, p-hydroxybenzoate, benzoate, p-t-butylbenzoate, p-aminosalicylate, clofibrate, halofenate, alpha-cyano-4-hydroxycinnamate and benfluorex. All of these drugs inhibit fatty acid biosynthesis by isolated rat liver cells, albeit with different effectiveness. In contrast, the cmpd have differential effects on fatty acid esterification and oxidation by isolated hepatocytes. An attempt is made to describe in molecular terms the underlying mechanisms of the acute inhibitory effects of the mono-aromatic derivatives on hepatic lipogenesis. It is proposed that all of the drugs exert an inhibitory action at the level of acetyl-CoA carboxylase, the enzyme generally considered to catalyze the rate-limiting step in hepatic fatty acid synthesis. This inhibitory effect may be either direct, i.e. by an alteration of the enzyme's structure as a results of interaction between drug and enzyme, or indirect, i.e. through a drug-induced change in the cellular levels of allosteric effectors of acetyl-CoA carboxylase.

Blood from tuberculosis patients was cultured before, during, and after withdrawal of therapy involving five different drug combinations if isoniazid, thiacetazone, p-aminosalicyclic acid, and streptomycin. The approaches used to detect DNA damage were chromosome aberrations and sister chromatid exchanges (SCEs). A total of 179 subjects were analyzed. In combo these drugs showed synergistic, additive, and antagonistic effects, though they were found to be nonclastogenic individually. Four of the drug combinations, isoniazid plus thiacetazone, isoniazid plus p-aminosalicyclic acid, isoniazid plus thiacetazone plus streptomycin, and isoniazid plus p-aminosalicyclic acid plus streptomycin, induced a significant incr in the frequency of aberrations, whereas isoniazid plus streptomycin did not induce aberrations. In fact, streptomycin appeared to reduce the frequency of aberrations. SCEs were incr in only two patients: one treated with isoniazid plus thiacetazone and the other with isoniazid plus p-aminosalicyclic acid. The frequency of aberrations after withdrawal of therapy was decr; it was slightly higher than the controls, though it was insignificant. The return to normalcy could be due to elimination of damaged cells or the repair of DNA in lymphocytes. Though the drug-induced aberrations do not persist after withdrawal of therapy, the chromosome damaging combo of drugs should be used with caution, because the possibility of meiotic chromosome damage in germ cells (during therapy), which might be passed on to the next generation, cannot be ruled out.

BIOAVAILABILITY STUDIES ON P-AMINOSALICYLIC ACID & ITS SALTS IN 12 SUBJECTS. COLORIMETRIC ASSAY INDICATED THAT PEAK BLOOD LEVELS OCCURRED @ 0.5, 0.75, 1.5, & 3 HR FOR SODIUM, POTASSIUM, & CALCIUM SALTS & P-AMINOSALICYLIC ACID, RESPECTIVELY.

URINE EXCRETION DATA SHOWED ABSORPTION TO BE ESSENTIALLY COMPLETE ALTHOUGH RATES OF ABSORPTION DIFFERED.

Aminosalicyclic acid is readily absorbed from the gastrointestinal tract. A single oral dose of 4 g of the free acid produces maximal concentrations in plasma of about 75 ug/ml within 1.5 to 2 hours. The sodium salt is absorbed even more rapidly. The drug appears to be distributed throughout the total body water and reaches high concentrations in pleural fluid and caseous tissue. However, values in CSF are low, perhaps because of active outward transport.

Over 80% of the drug is excreted in the urine; more than 50% is in the form of the acetylated compound. The largest portion of the remainder is made up of the free acid.

用途医薬原料。

使用antimycobacterial antitubercular;NF-kB inhibitor.4-Aminosalicylic acid (p-aminosalicylic acid, PAS), an antituberculosis drug, is a model active pharmaceutical ingredient to study salt and cocrystal formation in a multiple hydrogen-bonding functionality molecule with carboxylic acid, amine, and phenol groups.It has also been used as a second line agent to sulfasalazine in people with inflammatory bowel disease such as ulcerative colitis and Crohn's disease.It is typically taken by mouth.

一般的な説明4-Aminosalicylic acid occurs as a white to yellowish white crystalline solid that darkens on exposure to light or air. It is slightly soluble in water but more soluble in alcohol. Alkali metal salts and the nitric acid salt are soluble in water, but the salts of hydrochloric acid and sulfuric acid are not. The acid undergoes decarboxylation when heated. An aqueous solution has a pH of approximately 3.2. PAS is administered orally in the form of the sodium salt, usually in tablet or capsule form. Symptoms of gastrointestinal irritation are common with both the acid and the sodium salt. Various enteric-coated dosage forms have been used in an attempt to overcome this disadvantage. Other forms that are claimed to improve gastrointestinal tolerance include the calcium salt, the phenyl ester, and a combination with an anion exchange resin (Rezi-PAS). An antacid such as aluminum hydroxide is frequently prescribed. The oral absorption of PAS is rapid and nearly complete, and it is widely distributed into most of the body fluids and tissues, with the exception of the CSF, in which levels are significantly lower.It is excreted primarily in the urine as both unchanged drug and metabolites.
