Category: benzofurans. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: Sodium 4-butyl-3,5-dioxo-1,2-diphenylpyrazolidin-4-ide, is researched, Molecular C19H19N2NaO2, CAS is 129-18-0, about [Effect of] prostaglandins and prostaglandin antagonists on bovine pulmonary vein in vitro. Author is Burka, J. F.; Eyre, P..

Sodium meclofenamate [6385-02-0] and phloretin phosphates dimer blocked PGE2 (I) [363-24-6]-induced contractions of bovine pulmonary vein whereas relaxations were not blocked. Diethylcarbamazine citrate [1642-54-2] inhibited the relaxant effect of I but it also antagonized the contractile effects of histamine, 5-hydroxytryptamine, and PGF2α [551-11-1] so its action was rather nonspecific. Phenylbutazone Na [129-18-0] antagonized the contractile and relaxant actions of I and the contractile actions of PGF2α. By classifying receptors by antagonism, the bovine pulmonary vein appears to contain I phenylbutazone-type, I Na meclofenamate-type, I phloretin phosphate -type, and PGF2α phenylbutazone-type receptors.

Swiss mice were protected from i.p. lethal doses of phaloidin [17466-45-4] by phenylbutazone Na (I Na) [129-18-0] and rifampicin (II) [13292-46-1]. I, II, sulfadimethoxine Na [1037-50-9], or Bactrim, a mixture of sulfamethoxazole [723-46-6] and trimethoprim [738-70-5], were also prophylactically active against poisoning by an extract prepared from the whole mushroom (Amanita phalloides). Penicillin G [61-33-6] and I also showed curative effects against the extract in MAG mice. Protection against α-amanitin was provided in Swiss mice by I, aminopyrine [58-15-1], penicillin, chloramphenicol Na succinate [982-57-0], sulfadimethoxine, or Bactrim. Combined treatment, including especially Bactrim, penicillin and chloramphenicol, gave greater protection.

The antacidic effectiveness of Al(OH)3 is studied by the modified Fuchs’ method. The efficacy of the spray-dried gel is better than the one dried at low temperature The efficacy decreases in the order liquid gel, dried gel, and granules. Even if dried gel is suspended in water, its efficacy is not improved. The efficacy is related not only to the size of particles, but also to aging. Mech. mixture of dried gel and other antacids, such as Mg salts, did not improve the antacid efficacy, but such mixtures treated with water showed good result.

cf. C.A. 51, 12433f. Antihistaminics, contained in the preparations for colds with various other ingredients, can be determined colorimetrically by precipitation as reineckates. By regulating the pH of their solutions or changing the quantity of added MeOH, the differential determination from other basic ingredients is accomplished. For the determination of antihistaminics in the mixture of aspirin, phenacetin, and caffeine, samples are dissolved in water and the antihistamine is precipitated with 2% NH4 reineckate in MeOH solution In the presence of aminopyrine or antipyrine, Clark-Lubs’ buffer solution is added in order to hold the pH of the solution at 6.5-7.0, then NH4 reineckate is added. The reineckate of ephedrine or methylephedrine is more soluble in MeOH than that of antihistaminics. From preparations containing thiamine, free antihistamine base is extracted with Et2O after adding K2HPO4. The aqueous solution hereby obtained is used for the determination of thiamine as its reineckate. Antihistaminics in the mixture of aspirin, phenacetin, and caffeine are titrated as free bases by passing through a column of Amberlite IR-4B (OH form). As aspirin is adsorbed on the resin, it is eluted with 50% alc. solution of N HCl, and titrated by bromometry.

Recommanded Product: 129-18-0. Aromatic compounds can be divided into two categories: single heterocycles and fused heterocycles.

Author is Ammar, Elsayed M.; Elakkad, Ibrahim N.; Elbitar, Hussein H..

Daily oral treatment with the phenylbutazone-Na [129-18-0] or Na salicylate [54-21-7] for 2 weeks decreased the cardiac activity of digoxin (I) [20830-75-5], as indicated by an increase in its lethal dose in guinea pigs. The uptake of I by ventricular strips from rabbits, pretreated with phenylbutazone or sodium salicylate, was decreased, and this decrease may explain its decreased cardiac activity. Competition between the 2 antirheumatic drugs and I is discussed at both the plasma protein and the cardiac tissue levels. Thus, drug interactions and the subsequent decreased clinical effectiveness of I occur when I is prescribed in combination with phenylbutazone or sodium salicylate.
