“…The presence of lone pairs is attributed to its sp 2 hybridization as the compound is highly reactive due to carbon and nitrogen atoms. Due to the presence of strong properties like adaptability, simplicity, and functionality, these compounds are of high importance [11,12]. The significance is of high importance in biological assays that the Schiff bases can form diverse functional groups.…”
Schiff bases are a diverse group of organic compounds with great pharmaceutical importance due to the presence of carbon–nitrogen double bonds (–C=N–). These compounds are synthesized by the condensation reaction between a primary amine and an aldehyde or ketone in a suitable solvent such as methanol. These compounds have shown antibacterial, antifungal, antiviral, anti-inflammatory, and antioxidant activities, which have garnered the attention of organic chemists in synthesizing these compounds. Recent advances have been summarized in this review paper mainly including compounds with potential antibacterial, antifungal, and antiviral activities. Synthetic schemes are included to provide a better understanding of the Schiff base synthesis mechanism. This review paper will provide a way forward for the pharmaceutical chemist to synthesize new compounds with potential biological activities.

“…9,10 In addition, many drugs such as antibiotics possess better pharmaceutical properties when they are in the form of metal transition complexes. [11][12][13] From this perspective, the synthesis and characterization of new metal complexes and the evaluation of their antibacterial activities have been considered by the global community as part of the solution to overcome AMR. 14,15 Transition metal complexes with 1,10-phenanthroline ligands are of much interest since they display a wide variety of applications in organometallic chemistry, catalysis, electrochemistry, ring-opening metathesis polymerization and biochemistry.…”
Antimicrobial Resistance (AMR) to the current commercially available drugs is currently a serious global threat to the effective treatment of bacterial infections. The discovery of novel active compounds against new...
“…Synthetic macrocyclic complexes can mimic some naturally occurring macrocycles due to their resemblance with natural macrocycles, such as metalloproteins and metalloenzymes [2,3]. Macrocyclic complexes have applications in the field of biometallic activation and catalysis [4], pharmaceuticals [5] and pigments and dyes [6]. Macrocyclic compounds possess very good selective complexing properties [7,8] and their metal complexes are used as catalysts [9][10][11].…”
Three novel organotellurium decorated 10-membered tetraazamacrocyclic complexes of Co(II) were synthesized using template condensation of 1,1-diiodo-1-telluracyclopentane, 1,1-diodo-2-methyl-1-telluracyclopentane and 1,1-diiodo-1,1-diethyltellurium(IV) with 1,2-diaminopropane and cobalt dichloride hexahydrate in dry methanol in 2:2:1 molar ratio. The characterization of the synthesized cobalt(II) complexes was carried out using elemental analysis, spectroscopic studies (IR, proton NMR & proton decoupled carbon NMR) and molar conductance measurements. The results of these studies suggested that the complexes may be formulated as [CoLCl2] where L = {C4H8Te-(NHCH2CH(CH3)NH)}2, {C4H7(CH3)Te(NHCH2CH(CH3)NH)}2 and {(C2H5)2Te(NHCH2CH(CH3)NH)}2. The synthesized complexes were also screened for antimicrobial activity using broth microdilution and agar disc diffusion methods.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
