A novel route for the synthesis of Cu(II)-triazolophthalazine complexes using the Cu(II)-promoted cyclization dehydrogenation reactions of hydrazonophthalazines under reflux was presented. Two hydrazonophthalazines were cyclized to the corresponding triazolophthalazine ligands, 3-pyridin-2-yl-3,10b-dihydro-[1,2,4]triazolo[3,4-a]phthalazine (TPP) and 3-(3,10b-dihydro-[1,2,4]triazolo[3,4-a]phthalazin-3-yl)-benzoic acid (TP3COOH), followed by in situ complexation with Cu(II) yielding six novel Cu(II)-triazolophthalazine complexes depending on the reaction conditions. The molecular and supramolecular structures of the Cu(II)-triazolophthalazine complexes were discussed. The metal sites have rectangular pyramidal geometry in the [Cu(TPP)Cl-2](2); 1 and [Cu(TP3COOEt)Cl-2(H2O)](2); 4 dinuclear complexes, distorted square planar in [Cu(TP3COOMe)(2)Cl-2]; 3, [Cu(TP3COOH)(2)Cl-2]; 5 and [Cu(TP3COOH)(2)Cl-2]center dot H2O; 6 and a distorted octahedral in [Cu(TPP)(H2O)(2)(NO3)(2)]; 2. Hirshfeld analysis showed that the O horizontal ellipsis H, C horizontal ellipsis H, Cl horizontal ellipsis H (except TP3COOH and 2), N horizontal ellipsis H and pi-pi stacking interactions are the most important intermolecular contacts. The pi-pi stacking interactions are the maximum for TP3COOH and complex 6 with net C horizontal ellipsis C/C horizontal ellipsis N contacts of 19.4% and 15.4%, respectively. The orbital-orbital interaction energies of the Cu-N/Cu-Cl bonds correlated inversely with the corresponding Cu-N/Cu-Cl distances, respectively. The charge transfer processes between Cu(II) and ligand groups were also discussed. The charge densities of the Cu(II) centers are reduced to 0.663-0.995 e due to the interactions with the ligand groups coordinating it.

In the recent decades, N-heterocycles are widely used as versatile scaffolds for the development of biologically active compounds and considered as one of the privileged structures. Among the various N-heterocycles, benzodiazines, a series of bicyclic heterocycles in which benzene rings are fused with 6-membered heterocycles containing two nitrogens are especially interesting, due to their structural conciseness and usefulness as synthetic intermediates, and suitable physicochemical properties as potential drug candidates and chemical probes. For this reason, a series of synthetic methodologies for benzodiazines has been developed and generally used in organic and medicinal chemistry fields. Interestingly, synthesis of quinazoline, a kind of benzodiazine in which benzene is fused with pyrimidine, has been extensively reviewed, while cinnoline, phthalazine and quinoxaline, benzene fused with pyridazine or pyrazine, have been relatively less investigated. In this review, recent advances in the synthesis of biologically active benzodiazines, benzene ring-fused 6-membered heterocycles with two nitrogen atoms, cinnoline, phthalazine and quinoxaline, will be addressed. In each section, biological activities of various benzodiazines, recently served as novel scaffolds for drug discovery, are briefly summarized for comprehensive understanding of biological and medicinal significance in advance. Moreover, intensive investigation of the synthetic approaches to various benzodiazines such as cinnoline, phthalazine and quinoxaline is followed. It would hopefully be helpful for the readers who have interests in developing novel drug candidates and related useful chemical probes.

The use of hydrazinecarboxamides as a new class of carbamoylating agents has been established through the dehydrazinative Minisci reaction of electron-deficient nitrogen heteroarenes. A wide range of electron-deficient nitrogen heteroarenes, including isoquinoline, quinoline, pyridine, phenanthridine, quinoxaline, and phthalazine, underwent copper/acid-catalyzed oxidative carbamoylation with hydrazinecarboxamide hydrochlorides to afford structurally diverse nitrogen-heteroaryl carboxamides as single regioisomers in moderate to excellent yields. The functional group tolerance was substantially demonstrated in the direct carbamoylation of quinine obviating multistep sequences involving protecting groups and prefunctionalization of the heterocycle.

Dantrolene is used for malignant hyperthermia during anesthesia, and it sometimes causes severe liver injury as a side effect. Dantrolene is metabolized to acetylaminodantrolene, which is formed via the reduction of dantrolene to aminodantrolene and subsequent acetylation. Formation of hydroxylamine during the metabolic process may be associated with liver injury. We identified the enzymes responsible for dantrolene metabolism in humans to elucidate the mechanism of liver injury. Dantrolene reductase activity was not detected in human liver microsomes, but it was detected in cytosol. Formation was increased in the presence of N-1-methylnicotineamide, which is an electron donor to aldehyde oxidase 1 (AOX1). Potent inhibitors of AOX1 and a correlation study with a marker of AOX1 activity, namely phthalazine oxidase activity, in a panel of 28 human liver cytosol samples supported the role of AOX1 in dantrolene reduction. Acetylaminodantrolene formation from aminodantrolene was highly detected in recombinant N-acetyltransferase (NAT) 2 rather than NATI. A glutathione trapping assay revealed the formation of hydroxylamine via an AOX1-dependent reduction of dantrolene but not via hydroxylation of aminodantrolene. In conclusion, we found that AOX1 and NAT2 were responsible for dantrolene metabolism in humans and that AOX1-dependent metabolism determines dantrolene-induced liver injury.

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 2215-77-2. SDS of cas: 2215-77-2.

Chemistry is an experimental science, Safety of H-Glu(OBzl)-OH, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 1676-73-9, Name is H-Glu(OBzl)-OH, molecular formula is C12H15NO4, belongs to phthalazine compound. In a document, author is Gao, Cheng-Zhi.

A series of new Olaparib derivatives was designed and synthesized, and their inhibitory activities against poly (ADP-ribose) polymerases-1 (PARP-1) enzyme and cancer cell line MDA-MB-436 in vitro were evaluated. The results showed that compound 5l exhibited the most potent inhibitory effects on PARP-1 enzyme (16.10 +/- 1.25 nM) and MDA-MB-436 cancer cell (11.62 +/- 2.15 mu M), which was close to that of Olaparib. As a PARP-1 inhibitor had been reported to be viable to neuroprotection, in order to search for new multitarget-directed ligands (MTDLs) for the treatment of Alzheimer’s disease (AD), the inhibitory activities of the synthesized compounds against the enzymes AChE (from electric eel) and BChE (from equine serum) were also tested. Compound 5l displayed moderate BChE inhibitory activity (9.16 +/- 0.91 mu M) which was stronger than neostigmine (12.01 +/- 0.45 mu M) and exhibited selectivity for BChE over AChE to some degree. Molecular docking studies indicated that 5l could bind simultaneously to the catalytic active of PARP-1, but it could not interact well with huBChE. For pursuit of PARP-1 and BChE dual-targeted inhibitors against AD, small and flexible non-polar groups introduced to the compound seemed to be conducive to improving its inhibitory potency on huBChE, while keeping phthalazine-1-one moiety unchanged which was mainly responsible for PARP-1 inhibitory activity. Our research gave a clue to search for new agents based on AChE and PARP-1 dual-inhibited activities to treat Alzheimer’s disease.

A facile synthesis of functionalized 3-carbamide pyridazines starting from readily available chlorovinyl aldehydes and oxamic acid thiohydrazides via cascade imination/electrocyclization is reported. In the presence of p-toluenesulfuric acid, various ketones have been efficiently incorporated into the pyridazine derivatives through a two-step sequence involving a VilsmeierHaack reaction and imination. The synthetic value of this method has been demonstrated by efficient synthesis of steroidal pyridazines.
