Synthesis [1-(4-acetylphenyl)-3-(2-methylphenyl)]triazene: NMR, Vibrational, X-ray Crystallography Characterization with HF/DFT Studies

1 Synthesis , X - ray Crystal Structures , Computational 2 Studies and Catechol Oxidase Activity of New 3 Acylhydrazone Derivatives 4

To make low-cost catalytic materials that mimic the activity of tyrosinase enzymes 29 (Catechol oxidase) is an exciting challenge of biochemical technology. Herein, we report the 30 synthesis of a series of acylhydrazone-pyrazoles based biomolecule materials (L1-L7) with superior 31 catecholase activity. These biomolecules were synthesized by a one pot chemical condensation 32 between 5-methyl-...

The X-ray Transform and its Application in Nano Crystallography

In this article a review on the definition of the X- ray transform and some ofits applications in Nano crystallography is presented. We shall show that the X- raytransform is a special case of the Radon transform on homogeneous spaces when thetopological group E(n)- the Euclidean group - acts on ℝ2 transitively. First someproperties of the Radon transform are investigated then the relationship ...

Exposing hidden alternative backbone conformations 1 in X - ray crystallography using qFit 2 3 Daniel

Exposing hidden alternative backbone conformations 1 in X - ray crystallography using qFit 2 3

13 Proteins must move between different conformations of their native ensemble to perform their 14 functions. Crystal structures obtained from high-resolution X-ray diffraction data reflect this 15 heterogeneity as a spatial and temporal conformational average. Although movement between natively 16 populated alternative conformations can be critical for characterizing molecular mechanisms, it i...

Synthesis and Leishmanicidal Activity of 1-[5-(5-nitrofuran-2-yl)-1, 3, 4-thiadiazole-2-yl]-4-benzoylepiperazines

A series of (5-nitrofuran-2-yl)-1, 3, 4-thiadiazole-2-yl derivatives 6a–6e have been synthesized and screened for in vitro anti-leishmanial activity against the promastigote form of L. major. The structure of Schiff bases were confirmed by 1H NMR, IR. Screening results indicate that all of the designed and synthesized final compounds (6a-6e) significantly reduced the viability of promastigotes ...
