Background: Due to the divers biological applications of Cu(II) complexes, we in this study reports various complexes. The aims synthesize and assess new complexes as powerful β-glucuronidase inhibitors. Methods: Five Schiff base ligands their were synthesized, characterized, screened against inhibitory activity. Results: In series, compounds 3e, 3c, 2b, 2c ascribed inhibition ranging from (IC50 = 3.0 ± 0.7 µM) 19.2 0.8 µM). A precise particular arrangement atoms is suggested by triclinic...
To overcome the issue of multidrug resistant (MDR) microbes, exploration ways to improve antimicrobial efficiency existing antibiotics is one promising approaches. In search synthons with higher efficiency, in current investigations, cocrystal and amorphous salt levofloxacin hemihydrate (LEV) were developed phthalimide (PTH) caffeic acid (CFA). New materials characterized help FT-IR, Raman spectroscopy, powder X-ray diffraction (PXRD), differential scanning calorimetry (DSC)...
Waste Tire Carbon (WTC) was chosen as the carbon source for fabricating mercury sensor. Tires are inherently carbon-rich (88%) and considered elastomer blends. While WTC has been used a sensor detection, resulting sensitivity relatively low. Therefore, modifications to working electrode necessary improve detection. One such modification involves using nanoparticles, specifically zinc oxide (ZnO) doped with ion-imprinted polypyrrole (PPy). The modified electrodes ZnO PPy were characterized...

DFT studies used to assess the location protons in free ligands. However, calculations have shown that, all cases, hydrogen bonding from either N–H group gives conformations that are very...
A series of N-pivaloyl-N′-(alkyl/aryl)-N′′-pyridylguanidine general formula C4H9CONHC(NR1R2)NPy have been synthesized and characterized using elemental analysis, FT-IR, multinuclear NMR spectroscopy, in the case compounds 7 11, by single crystal X-ray diffraction (XRD). The guanidines were tested for antitumor activities against potato tumor, showed excellent inhibition Agrobacterium tumefaciens (AT10)-induced tumor. antioxidant antimicrobial these new various bacterial fungal strains also...
The reaction of 1,3-Diisobutyl thiourea (Tu) with metal salts, {[CuX (X = Cl, I)], [ZnCl2] and [HgI2] in an appropriate stoichiometric ratio afforded the corresponding complexes [Tu2CuCl] (1), [Tu3CuI] (2), [Tu2ZnCl2] (3) [Tu2HgI2] (4) good yields. FT-IR data show typically broad signals (3278–3288 cm−1) attributed to involvement NH bonds extensive hydrogen bonding. structures were proposed based on a spectroscopic set. Compounds 1 2 additionally characterized by single-crystal X-ray...
