Synthesis ,Spectral Investigation, Anticancer Study of Azo-Imine Heterocyclic Compounds
Abstract: Many Schiff base reactions are known within a famous series of addition reactions to the azomethine group, where reagents are added to the polarized double bond and the nucleophilic (nucleophilic) reagents attack the carbon atom in the azomethine bond.. An example of this type of reaction is the addition of alkyl halides, which produces quaternary amine salts, which in turn are converted to the secondary amine. These compounds have an …

Chompound contaning oxadiazole derivatives and their potential therapeutic uses.
Abstract: Derivatives of oxadiazole or furadi azole rings constitute a significant class of heterocyclic substances. Oxadiazole is a heterocyclic, five-membered ring with two carbons, one oxygen atom, two nitrogen atoms, and two double bonds. They are produced by substituting two nitrogen (-N =) atoms for two methylene groups (= CH) in furan. The furan ring's aromaticity was significantly decreased by substituting these groups, resulting in a conjugated diene character. There were …
