Abstract

In this study, we successfully synthesized an innovative 1D-Zn(II) coordination polymer, denoted as [Zn(L)(H2O)2]n, employing the Schiff base {4-[(2-hydroxy-3-methoxy-benzylidene)-amino]-benzoic acid} (H2L). The Schiff base was obtained through the reaction of 4-aminobenzoic acid and o-vanillin under slow volatilization conditions. The resulting compound exhibits remarkable green fluorescence emission properties, indicating its potential as a novel fluorescent and sensing material. Hydrogels based on hyaluronic acid (HA) and carboxymethyl chitosan (CMCS), denoted as HA/CMCS hydrogels, were synthesized using a chemical method. Additionally, we utilized bleomycin as a model drug to synthesize a novel bleomycin metal gel and assessed its anti-hemangioma activity. Molecular docking simulations revealed that the Zn complex can form stable bonds with the key target, involving the methoxy and carboxyl groups on the Zn complex.
