The main objective presents research work to synthesize, characterization, and in-vivo evaluation of Pyridazine derivatives To study the different synthesized derivatives by using different anal. parameters like IR, Mass, and NMR anal. And also find out the antihypertensive activity. The studies on the hydralazine group drugs led to the synthesis of many Pyridazine derivatives with a wide activity spectrum on the cardiovascular system. Pyridazine derivatives, a class of compounds containing the N-N bond, exhibit a wide range of pharmacol. activities such as antidepressant, antihypertensive and cardiotonic, etc. Some 7-phenyl-3, 4, 8, 9-tetrahydro-2H-pyridazino [1, 6-a] [1, 3, 5] triazin-2-imine were synthesized by reacting 6-Ph substituted 2, 3, 4, 5-Tetrahydro pyridazin-3-one with cyclic secondary amine under Mannich reaction conditions. The total seven compounds (vj1-vj7) were synthesized under Mannich reaction conditions. All the synthesized derivatives were selected for evaluation of antihypertensive activities by a noninvasive method using Tail Cuff method. Most of the compounds showed good antihypertensive activity. Few compounds like vj4, vj5, and vj6 were found to show a highly significant reduction in mean arterial blood pressure but at a higher dose in comparison to standard drugs like proponolol and hydralazine. The substituted pyridazine derivatives discovered in this study may provide valuable therapeutic intervention for the treatment of hypertension.

Densities of dilute aqueous solutions of 1-monomethyl-2-thiourea and 1,1,3-trimethyl-2-thiourea have been measured using an Anton Paar DMA 5000 M vibrating-tube densimeter. The apparent molar volumes and expansibilities (down to infinite dilution) have been calculated from the obtained d. data. The experiments have been performed in the temperature range between (278.15 and 318.15) K, with a step of 10 K, at p ? 0.1 MPa. The influence of a nature of methyl-N-sited substituents on the structure-packing properties of aqueous thioureas has been discussed. A possibility to estimate the standard (limiting apparent or partial) molar volumes for asym. substituted 1,1-dimethyl-2-thiourea in water has been considered, too.

The floatabilities of natural zeolite, quartz feldspar, 1:1 mixture of natural zeolite-quartz, and 1:1 mixture of natural zeolite-feldspar were investigated by the Denver-type laboratory flotation machine using dodecylammonium acetate (I) and pine oil as a collector. The Cs adsorption capacity of zeolite recovered by I flotation in the acidic state < pH 2, was less than that of the natural zeolite. However, the capacity was improved when treated with 1N NaOH or 1N KCl. Quartz and feldspar were separated from natural zeolite by I flotation in a HCl or H2SO4 circuit at pH 0.5-2, but not in neutral or alk. pH range. The selective separation of zeolite from the mixture of natural zeolite-quartz or natural zeolite-feldspar was achieved by using I (100 mg/L) at pH 1.1 together with pine oil (46 mg/L) as a collector. The recovery and the content of zeolite as froth were about 83 and 77%, resp.

Toxicology in Vitro published new progress about 3115-28-4. 3115-28-4 belongs to catalysis-chemistry, auxiliary class Aliphatic Chain, name is 2-Butylhexanoic acid, and the molecular formula is C10H20O2, Category: catalysis-chemistry.

Herrmann, K. published the artcileEffects of the anticonvulsant drug valproic acid and related substances on the early development of the zebrafish (Brachydanio rerio), Category: catalysis-chemistry, the publication is Toxicology in Vitro (1993), 7(1), 41-54, database is CAplus and MEDLINE.

The early development of the zebrafish Brachydanio rerio is being investigated as a possible test system for prescreening drugs suspected to be hazardous to humans. Experiments have been carried out to evaluate the teratogenic effect of the human antiepileptic drug valproic acid (VPA) and several chem. related substances. The experiments show the highly synchronous development of zebrafish embryos, even of batches laid by different parents. Effects due to drug treatment can be easily and accurately determined VPA causes retardation and cessation of development. It generate malformations such as edema, brain deformities, a shortened and bent tail, and bipartite axiation of the posterior trunk. The effects of the various substances tested were estimated and compared by measuring retardation of development. The related substances display similar effects, but differ in their effectiveness as they do in other test systems: 2-en-valproic acid and 4-en-valproic acid display weaker effects than VPA and propylhexanoic acid. Valpromide, methylhexanoic acid, pentenoic acid and diethylacetic acid display a weak effect or no effect at all. The effects in zebrafish appear to be more similar to those observed in hydroids and in mammalian whole embryo culture systems than to the effects in mammals in vivo. Differences may be best explained by differences in uptake and degradation of the drugs, and by the influence of the maternal organism in mammals.
