In the present study, we have carried out extensive General Unrestricted Structure-Activity Relationships, conventional 3D-Quantitative Structure-Activity Relationships, and CoMFA analyses of synthetic prodiginines displaying moderate to high activities against Plasmodium Falciperum. 2D and 3D descriptors, various statistical parameters viz. R(2),(More)
Cadmium is a non-essential toxic metal used in industrial process, causes severe risk to human health. Selenium (Se) is an essential trace mineral of fundamental importance for human health. Selenium has antioxidant enzymes roles and is needed for the proper function of the immune system. In this study, the protective effects of selenium against cadmium(More)
Quantitative Structure–Activity Relationship not only provides guidelines regarding structural features responsible for biological activity but it can be used also for prediction of desired activity prior to synthesis of untested chemicals. Therefore, an appropriate validation of any QSAR is of utmost importance to judge its external predictive ability.(More)
Herein, we report the design and calculated molecular properties of ten existing azo Schiff bases 5a–h and 7a, b. On the basis of a hypothetical antibacterial pharmacophore, the structures are designed to interact with Gram-positive and Gram-negative bacteria. The in vitro biological evaluation of these compounds allowed us to point out new potential(More)
A new series of oxovanadium(IV) complexes have been designed and synthesized with a new class of triazole Schiff bases derived from the reaction of 3,5-diamino-1,2,4-triazole with 2-hydroxy-1-naphthaldehyde, pyrrole-2-carboxaldehyde, pyridine-2-carboxaldehyde and acetyl pyridine-2-carboxaldehyde, respectively. Physical (magnetic susceptibility, molar(More)
Several successfully methods to prepare Copper(II)-oxide (Cu=O) nanostructures with different sizes and shapes and their applied in different man daily life applications were investigated in this study. This paper discusses different Cu=O nanostructures synthesis methods and their characterization as well as their applications. The pulsed wire explosion(More)
Tautomerism is an important aspect associated with a variety of pharmacologically and biologically active compounds. It is a challenge to account for tautomerism in computer-aided drug designing (CADD). The estimations and calculations of many physico-chemical properties and theoretical descriptors of the molecules are sensitive to tautomerism. In this(More)
Synthesis and evaluation of the bioactivity of spiroheterocycles (STC) against Trypanosoma cruzi are described. Selectivity indices were improved for two compounds versus the leads 17 and 20, the spiro-thiochromanone (STC) derivatives 17–26, thus increasing the therapeutic interest of our family. As our previous studies conducted on the structure of(More)
A series of new 2-aminobenzamide derivatives (1-10) has been synthesized in good to excellent yields by adopting both conventional and/or a time-efficient microwave assisted methodologies starting from isatoic anhydride (ISA) and characterized on the basis of their physical, spectral and microanalytical data. Selected compounds of this series were then(More)
This paper reports the computational evaluation and experimental verification of 7-hydroxy-3-(1-phenyl-3-aryl-1H-pyrazol-5-yl)-4H-chromen-4-ones 3 and their o-β-d-glucopyranosides 5 for their antimicrobial and antioxidant activity. The prepared compounds were tested against various Gram-positive and Gram-negative bacteria species. Some of the synthesized(More)
