Sulfonyldibenzoate coordination polymers as bioactive dopants for polysaccharid...

This work describes the preparation, characterization, and antimicrobial properties of bioactive silver(I) and copper(II) coordination polymers (bioCPs) and derived biopolymer materials. Two bioCPs, [Ag2(6-sdba)]n (1) and [Cu(4-sdba)H2O]n·1.5nH2O (2), were assembled from metal salt precursors and 4,4-sulfonyldibenzoic acid (H2sdba). Both compounds were used as dopants for preparing hybrid biopolymer films based...

Promising anticancer agents based on 8-hydroxyquinoline hydrazone copper(II) co...

We report the synthesis and characterization of a group of benzoylhydrazones (Ln) derived from 2-carbaldehyde-8-hydroxyquinoline and benzylhydrazides containing distinct para substituents (R = H, Cl, F, CH3, OCH3, OH and NH2, for L1-7, respectively; in L8 isonicotinohydrazide was used instead of benzylhydrazide). Cu(II) complexes were prepared by reaction of each benzoylhydrazone with Cu(II) acetate. All compou...

Degradable copper(ii)-doped starch-based biopolymeric films with antibacterial ...

The search for new bioactive molecules and sustainable materials to address antimicrobial resistance continues to be of significant attention in many research areas. In this work, new copper(II) coordination polymers and complexes containing ammonia and aromatic carboxylate ligands were self-assembled, characterized, and applied as bioactive dopants to produce starch-based biopolymeric films. The structures of ...

Color Polymorphs of ROY-ol

Color polymorphism is a fascinating property exhibited by compounds that have polymorphs of different colors. The most famous family of substances forming molecular organic color polymorphs is the ROY family of compounds. ROY, which states for the red, orange, and yellow colors of the polymorphs of 5-methyl-2-((2-nitrophenyl)amino)thiophene-3-carbonitrile, is currently the compound exhibiting the largest number...

Hybrid silver(I)-doped soybean oil and potato starch biopolymer films to combat...

This study describes the preparation, characterization, and antimicrobial properties of novel hybrid biopolymer materials doped with bioactive silver(I) coordination polymers (bioCPs). Two new bioCPs, [Ag2(6-hfa)]n (1) and [Ag2(4-nda)(H2O)2]n (2), were assembled from Ag2O and homophthalic (H2hfa) or 2,6-naphthalenedicarboxylic (H2nda) acids as unexplored building blocks. Their structures feature 2D metalorganic...

Silver(I) coordination polymers immobilized into biopolymer films for antimicro...

This study describes a template-mediated self-assembly synthesis, full characterization, and structural features of two new silver-based bioactive coordination polymers (CPs) and their immobilization into acrylated epoxidized soybean oil (ESOA) biopolymer films for antimicrobial applications. The 3D silver(I) CPs [Ag4(?8-H2pma)2]n·4nH2O (1) and [Ag5(?6-H0.5tma)2(H2O)4]n·2nH2O (2) were generated from AgNO3 and p...

Synthesis of novel pyrazolo[3,4-b]quinolinebisphosphonic acids and an unexpecte...

Novel pyrazolo[3,4-b]quinoline α-ketophosphonic and hydroxymethylenebisphosphonic acid compounds were synthesized using different methodologies, starting from 2-chloro-3-formylquinoline 1. New phosphonic acid compounds were obtained as N-1 derivatives with a side chain with 1 or 3 (n = 1 or 3) methylene groups. All phosphonic acid compounds and their corresponding ester and carboxylic acid precursors were fully ...

New C-3 Substituted 1H- and 2H-Indazolephosphonic Acid Regioisomers: Synthesis,...

Indazole is known as an important structural motif in medicinal chemistry and, recently, has also gained attention in other areas, such as materials chemistry, with many studies showing different potential applications for their regioisomers. Phosphonates are also a class of compounds with diverse applications, ranging from medicinal to material applications. Here we present the synthesis of 1H- and 2H-indazole...
