EPR spectral study of copper(II) chelates with hetarylhydrazones of glyoxylic acid

Structure of copper(II) chelates based on glyoxylic hetarylhydrazones containing benzazole (quinoxaline and phthalazine) fragments have been studied by EPR spectroscopy. Spectral parameters in polycrystalline state and dimethylformamide solutions have been determined. Spectral parameters of benzimidazole derivative are typical for square planar structure of the chelate node, while phthalazine derivative displays formation of polymeric structures due to reduction of copper(II) atom.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 41263-74-5, you can contact me at any time and look forward to more communication. Recommanded Product: 4-(Methylamino)-3-nitrobenzoic acid.

Thermodynamic and Kinetic Studies of the Radical Scavenging Behavior of Hydralazine and Dihydralazine: Theoretical Insights

Hydralazine (HZ) and dihydralazine (DHZ) are phthalazine derivatives substituted at position 1 (HZ) or positions 1 and 4 (DHZ) by a hydrazinyl substituent. These compounds are widely used for treating hypertension and heart failure, essentially acting as vasodilators on the arteries and arterioles. In this study, the antioxidant activity of HZ and DHZ in the gas phase and in physiological environments was investigated by thermodynamic and kinetic calculations. It was found that the HOO center dot radical scavenging activity of these compounds follows the formal hydrogen transfer (FHT) mechanism. The H abstraction of the N9-H bond plays a deciding role in the HOO center dot radical scavenging of HZ-1 and DHZ-I, whereas the HOO center dot radical scavenging activities of HZ-2 and DHZ-2 are defined by the dissociation of the N10-H and Nil-H bonds, respectively. The rate constants for the HOO center dot radical scavenging of the HZ and DHZ in the gas phase are in the range of 9.64 x 10(6) to 4.52 x 10(8) M-1 s(-1), whereas in aqueous solutions and the lipid medium they are in the range of 2.62 X 10(4) to 5.13 x 10(7) M-1 s(-1) and 5.75 x 10(4) to 6.66 x 10(6) M-1 s(-1), respectively. The HOO center dot radical scavenging of DHZ-1 and DHZ-2 is thus faster than that of the reference antioxidant compound Trolox in all the studied environments. Consistently, DHZs are not only vasodilators but also potent antioxidants.

2H-Indazolo[2,1-b]phthalazine-trione derivatives: Inhibition on some metabolic enzymes and molecular docking studies

In this study, substituted 2H-indazolo[2,1-b]phthalazine-1,6,11-trione compounds (4a-d) obtained via one-pot three-component condensation reaction of aromatic aldehydes, cyclic 1,3-dione, and phthalhydrazide in ethanol catalyzed by Y(OTf)(3) showed satisfactory inhibitory effects against some important enzymes. Also, these molecules had K-i values in the row of 185.92 +/- 36.03-294.82 +/- 50.76 nM vs carbonic anhydrase I (CA I), 204.93 +/- 46.90-374.10 +/- 83.63 nM against human CA II, 937.16 +/- 205.82-1021.83 +/- 193.66 nM against alpha-glycosidase (alpha-Gly), respectively. For cholinesterase enzymes, the K-i values were found in the range of 47.26 +/- 9.62-72.05 +/- 19.47 nM against acetylcholinesterase (AChE) and 65.03 +/- 9.88-102.83 +/- 25.04 nM against butyrylcholinesterase (BChE), respectively. The inhibition effects of these compounds against enzymes whose name are AChE, BChE, alpha-Gly, hCA I, and hCA II, were compared with control molecules like tacrine, acarbose, and acetazolamide.
