Tetrabutyl phosphonium sulfate ([TBP](2)SO4), as novel room-temperature ionic liquid (RTIL), was synthesized by a simple cost-effective method, characterized by H-1, C-13, P-31 NMR and FT-IR spectrophotometry. The newly prepared catalyst was used as an efficient catalyst in some four multicomponent reactions (4MCRs) e. g., to synthesis pyridazino[1,2-a]indazole, indazolo[2,1-b]phthalazine and pyrazolo[1,2-b]phthalazine. This green method has several advantages such as short reaction time, using simple methods to prepare catalysts and products, easy operation and high efficiency of products. In addition, the catalyst can be easily recovered and reused several times with reduced average activity. Graphic abstract

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 36809-26-4. Quality Control of (4-Bromophenyl)diphenylamine.

Let’s face it, organic chemistry can seem difficult to learn. Especially from a beginner’s point of view. Like 36809-26-4, Name is (4-Bromophenyl)diphenylamine. In a document, author is Yu, Li-Jun, introducing its new discovery. Recommanded Product: (4-Bromophenyl)diphenylamine.

In a previous research, we found a compound named 6-(3-(trifluoromethyl)-benzyloxy)-[1,2,4]triazolo[3,4-a]phthalazine (BM-1) much more effective in the maximal electroshock (MES) model for mouse and much safer in the neurotoxicity (NT) screening, which indicated that it may be used as antiepileptic drug. But, those evaluations were too rough. So in this study, we did more work to assess the anticonvulsant activity and the toxicity about BM-1. The peak times of protection of BM-1 after intraperitoneal injection (ip) and oral administration (po) were determined using the MES test, and the anticonvulsant activity of it was compared with the reference drug, carbamazepine, at these peak times. The rotarod test was applied to measure its neurotoxicity. When compared with the reference drug in the maximal electroshock (MES) test at the time to peak effect, it showed that BM-1 was much more effective and safer than reference drug Carbamazepine with ED50 of 11.2 mg/kg, TD50 of 72.2 mg/kg and PI of 6.5 after administration of ip, while when administered orally, that values of ED50, TD50 and PI of BM-1-1, BM-1-2 and BM-1-3 were much better than Carbamazepine and BM-1 after po. The compound BM-1 has more effective anticonvulsant activity and lower neurotoxicity administered by both ip and po. So BM-1 could may be used instead of the prescribed antiepileptic drugs (AEDs) in the future.

Design, synthesis, structure-activity relationship and mechanism of action studies of a series of 4-chloro-1-phthalazinyl hydrazones as a potent agent against Leishmania braziliensis

With the aim to identify a potential drug candidate to treat cutaneous leishmaniasis, a series of 1-phthalazinyl hydrazones were synthesized and tested against Leishmania braziliensis parasite, one of the main responsible of this disease in the world. A structure-activity relationship permitted to identify two phthalazines containing nitroheterocyclic moiety 31 and 3m as promising new lead compounds. These compounds showed a significant antileishmanial activity against promastigote form of L. braziliensis, with EC50 values in sub-micromolar and nanomolar ranges. The phthalazine 31 also displayed a selective and excellent activity against the clinically relevant intracellular amastigotes form, with a EC50 value in sub-micromolar range (0.59 mu M), without affecting the viability of the host cells. Oxidative stress was identified as the possible mode of action of the most active phthalazine. Considering their significant antileishmanial activity and ease synthesis, the phthalazine containing nitroheterocyclic represents a promising agent against Leishmania braziliensis for the rational design of new leads.

A convenient, environmentally friendly and efficient procedure for the synthesis 3,4-dihydro-1H-indazolo[1,2-b]phthalazine-1,6,11(2H,13H)-trione derivatives has been developed via multi-component and one-pot reactions of various aldehydes with cyclic 1,3-diketones and phthalhydrazide 1,1,1,3,3,3-hexafluoro-2-propanol (HFIP). In simple and mild reaction conditions, the use of HFIP is explored as an easy workup and a green catalyst for the one-pot three-component synthesis of 3,4-dihydro-1H-indazolo[1,2-b]phthalazine-1,6,11(2H, 13H)-triones.

A DFT Study of Electronic Structures and Relative Stabilities of Isomeric n,m-Diazaphenanthrenes

In this study, the structural properties, energetic data, and classification of the chemical properties of n,m-diazaphenanthrine derivatives were studied by a density functional theory (DFT) method. The important and proper indices were applied in this investigation. The structures, electronic properties, and chemical reactivities of 25 isomeric n,m-diazaphenanthrenes were studied by a B3LYP/6?31+G(d) method/basis set. All the optimized geometries of these isomers kept good planarity. The structural properties such as bond lengths and dipole moments of these isomers were calculated. The energies of frontier orbitals (HOMO and LUMO) are used to determine several chemical reactivity parameters as a measure of their relative stabilities. These include total energy (E), ionization potential (I), electron affinity (A), chemical hardness (?), chemical softness (S), electronic chemical potentials (?), and electrophilicity (?). Based on these calculations, the heats of formation (?H?(f)) for all the n,m-diazaphenanthrine derivatives are predicted. Benzo[h]quinazoline (P-13) and benzo[f]cinnoline (P-34) are calculated to be the most stable and the least stable isomers, respectively. 1,10-Phenanthroline (P-110) possesses the minimum electrophilicity, while benzo[c]cinnoline (P-56) is calculated to have the highest electrophilicity among the isomeric structures. The largest and smallest dipole moments are calculated for benzo[f]phthalazine (P-23) and 3,8-phenanthroline (P-38), respectively. Linear relationships between the calculated E-LUMO (in eV) values and electrophilicity (?) of the isomeric n,m-diazaphenanthrenes were observed.
