In this paper, a series of 6-substituted-pyrido[3,2-e][1,2,4] triazolo[4,3-a] pyrazine derivatives have been synthesized. Their anticonvulsant activity and neurotoxicity in mice were evaluated by maximal electroshock (MES) and rotarod test, respectively. The structures were confirmed by H-1 NMR, C-13 NMR, MS and HRMS. The experimental results show that 6-phenoxypyrido[3,2-e][1,2,4] triazolo[4,3-a]pyrazine (5g) was safer than the reference drug, carbamazepine, with ED50 value of 93.9 mg.kg(-1) and protective index (PI) value of 24.3, which was a potential anti-epilepsy candidate compound.

The dynamic chemical diversity of the numerous elements, ions and molecules that constitute the basis of life provides wide challenges and opportunities for research. In an article, author is Hamidinasab, Mandia, once mentioned the application of 88-44-8, Name is 4-Aminotoluene-3-sulfonic acid, molecular formula is C7H9NO3S, molecular weight is 187.2163, MDL number is MFCD00007908, category is phthalazine. Now introduce a scientific discovery about this category, SDS of cas: 88-44-8.

Organo-Sulfonic acid tags anchored on magnetic titana coated NiFe2O4 nanoparticles (nano-NiFe2O4@TiO2-SiO2-Pr-DEA-OSO3H) was prepared and characterized by various analysis methods including Fourier transform infrared (FT-IR) spectroscopy, field emission scanning electron microscopy (FE-SEM), energy dispersive X-ray spectroscopy (EDS), vibrating sample magnetometer (VSM), X-ray diffraction (XRD) and thermo gravimetric analysis (TGA). These modified nanoparticles were used as efficient and recoverable hybrid nanocatalyst in multicomponent synthesis of some phthalazine-trione and benzo[4,5]imidazo[1,2-a]pyrimidine derivatives under green conditions. High yields within shorter reaction times, simple purification, and environmentally mild reaction conditions are some advantages of this protocol.

A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 88-44-8. SDS of cas: 88-44-8.

In a document, author is Zbancioc, Ana Maria, introduce the new discover.

Herein we report a feasible study concerning the design, syntheses and in vitro antimicrobial and antitumoral activities of some novel compounds with dihydroxyacetophenone (DA) moiety. An efficient and general method for the preparation of diazine with dihydroxyacetophenone (DDA) skeleton under conventional thermal heating (TH), microwave (MW) and ultrasounds (US) irradiation is presented. Antimicrobial and antitumoral tests prove that some dihydroxyacetophenone compounds (the brominated derivatives BrDA 3) have a significant biological activity. It is also to be pointed out that, basically all the dihydroxyacetophenone derivatives proved to have a powerful antibacterial activity against drug resistant Gram-negative strain Pseudomonas aeruginosa ATCC 27853. Of particular interest could be the excellent antibacterial activity of our dihydroxyacetophenone compounds against drug resistant Gram-negative strain Pseudomonas aeruginosa.

In a article, author is Sanchez-Moreno, Manuel, introduce new discover of the category.

A series of new phthalazine derivatives 1-4 containing imidazole rings were prepared. The monoalkylamino substituted. derivatives 2 and 4 were more active in vitro against T. cruzi and less toxic against Vero cells than both their disubstituted analogues and the reference drug benznidazole. Compounds 2 and 4 highly inhibited the antioxidant parasite enzyme Fe-SOD, and molecular modeling suggested that they interact with the H-bonding system of the iron atom moiety. In vivo tests on the acute phase of Chagas disease gave parasitemia inhibition values twice those of benznidazole, and a remarkable decrease in the reactivation of parasitemia was found in the chronic phase for immunodeficient mice. Glucose metabolism studies showed that compounds 1-4 did not affect the succinate pathway but originated important changes in the excretion of pyruvate metabolites. The morphological alterations found in epimastigotes treated with 1-4 confirmed extensive cytoplasm damage and a high mortality rate of parasites.

In a patnet, author is Berber, Nurcan, once mentioned the new application about 66-99-9.

A new series of phthalazine substituted urea and thiourea derivatives were synthesized, and their inhibitory effects on the activity of purified human carbonic anhydrases (hCAs I and II) were evaluated. 2H-Indazolo[2,1-b]phthalazine-trione derivative (1) was prepared with 4-nitrobenzaldehyde, dimedone, and phthalhydrazide in the presence of TFA in DMF, and nitro group was reduced to amine derivative (2) with SnCl2 center dot 2H(2)O. The compound was reacted with isocyanates and isothiocyanates to get the final products (3a-p). The results showed that all the synthesized compounds inhibited the CA isoenzymes activity. 3a (IC50 = 6.40 mu M for hCA I and 6.13 mu M for hCA II) has the most inhibitory effect. The synthesized compounds are very bulky to be able to bind near the zinc ion, and they much more probably bind as the coumarin derivatives.

Pathogenic fungi are one of the main causes of hospital-related infections. Since conventional antifungals have become less effective because of the increasing fungal resistance to the standard drugs, the need for new agents is becoming urgent. Herein we report a synthesis of a series of novel N-[imino-(1-oxo-(1H)-phthalazin-2-yl) methyl]benzenesulfonamide derivatives with in vitro activity against yeast-like fungi isolated from the oral cavity and respiratory tract of patients with candidiasis. These compounds were synthesized by the one-step or two-step reactions of 1-(2-alkylthiobenzensulfonyl)-2aminoguanidines with the appropriate ortho-carbonyl benzoic acids. The biological study revealed that new derivatives have shown significant growth-inhibitory activity, superior or comparable, than those of the reference drug fluconazole. The most promising activities were observed against Candida albicans, with inhibition at least 1-3 (12.5%-37.5%) of the eight tested strains at the low MIC level of <= 6.2-25 mu g/mL. Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 611-73-4, in my other articles.
