2-[6-(Morpholin-4-yl)pyridin-3-ylamino]acetohydrazide () was obtained starting from 6-morpholin-4-ylpyridin-3-amine () via the formation of ester () and then converted to the corresponding Schiff bases () with the reaction with aromatic aldehydes. The carbothioamide (), obtained from the reaction of hydrazide with phenylisothiocyanate, was converted to the corresponding 1,2,4-triazole () and 1,3,4-thiadiazole () derivatives by the treatment with NaOH or HSO, respectively. The cyclocondenzation of with 4-chlorophenacyl bromide or ethyl bromoacetate produced the corresponding 1,3-thiazole () or 1,3-thiazolidine derivatives (), respectively. Antimicrobial and antiurease activities of newly synthesized compounds were investigated. Some of them were found to be active on , and they displayed activity toward and in high concentration. Compound proved to be the most potent showing an enzyme inhibition activity with an IC = 2.37 ± 0.19 μM.

The global rise in antibiotic resistance has posed significant challenges to the effective management of Helicobacter pylori (H. pylori), a gastric pathogen linked to chronic gastritis, peptic ulcers, and gastric cancer. Conventional antibiotic therapies, while effective, face significant challenges, such as increasing antibiotic resistance, high recurrence rates, and adverse effects such as gut microflora dysbiosis.

This study assesses the antimicrobial, antibiofilm, and antiurease properties of selenium (Se), zinc (Zn), and zinc selenide (ZnSe) nanoparticles (NPs) against clinically pathogenic strains of Streptococcus salivarius and Proteus mirabilis. The Se, Zn, and ZnSe NPs, synthesized by Pseudomonas aeruginosa OG1, were characterized using transmission electron microscopy (TEM) revealing average sizes of approximately 30 ± 10 nm, 30 ± 15 nm, and 40 ± 10 nm, respectively. Atomic force microscopy (AFM) was used to examine the morphological and topological characteristics of the NPs.

Several novel copper (II) complexes of reduced Schiff bases containing fluoride substituents were prepared and structurally characterized by single-crystal X-ray diffraction. The complexes exhibited diverse structures, with the central atom in distorted tetrahedral geometry. The biological effects of the products were evaluated, specifically their cytotoxicity, antimicrobial, and antiurease activities, as well as affinity for albumin (BSA) and DNA (ct-DNA).
