“…Recently, the fabrication of LDH-based clay nanocomposites has gained ever-increasing interests. For example, copper (Cu(II)) or cobalt (Co(II)) sulfamerazine–salicylaldehyde complexes were used to intercalate the Mg-Al-LDH that was synthesized by a co-precipitation route [ 39 ]. In this research, Mg-Al-LDH composite, which exhibited promising antimicrobial activity against both gram-positive ( Staphylococcus aureus ) and gram-negative ( Escherichia coli ) bacteria, was prepared via a two-step delaminating/restacking method.…”

Owing to the hypoxia status of the tumor, the reactive oxygen species (ROS) production during photodynamic therapy (PDT) of the tumor is less efficient. Herein, a facile method which involves the synthesis of Mg–Mn–Al layered double hydroxides (LDH) clay with MoS2 doping in the surface and anionic layer space of LDH was presented, to integrate the photo-thermal effect of MoS2 and imaging and catalytic functions of Mg–Mn–Al LDH. The designed LDH-MoS2 (LMM) clay composite was further surface-coated with bovine serum albumin (BSA) to maintain the colloidal stability of LMM in physiological environment. A photosensitizer, chlorin e6 (Ce6), was absorbed at the surface and anionic layer space of LMM@BSA. In the LMM formulation, the magnetic resonance imaging of Mg–Mn–Al LDH was enhanced thanks to the reduced and acid microenvironment of the tumor. Notably, the ROS production and PDT efficiency of Ce6 were significantly improved, because LMM@BSA could catalyze the decomposing of the overexpressed H2O2 in tumors to produce oxygen. The biocompatible LMM@BSA that played the synergism with tumor microenvironment is a promising candidate for the effective treatment of cancer.

“…Sulfamerazine and Salicylaldehyde Offer good antimicrobial activity [102] Ciprofloxacin is fluoroquinolone antibiotic, broad-spectrum antimicrobial and is an important class of drugs for both human and animal health [103]. Its nanopesticide complex with Mg/Al-LDH gave higher thermal stability and other CRF properties, resulting in its superior quality compared with its counterpart [97].…”

The rapid growth in the human population has triggered increased demand for food supply, and in turn has prompted a higher amount of agrochemical usage to meet the gaps between food production and consumption. The problem with conventional agro-nanochemicals is the reduced effectiveness of the active ingredient in reaching the target, along with leaching, evaporation, etc., which ultimately affect the environment and life, including humans. Fortunately, nanotechnology platforms offer a new life for conventional pesticides, which improves bioavailability through different kinetics, mechanisms and pathways on their target organisms, thus enabling them to suitably bypass biological and other unwanted resistances and therefore increase their efficacy. This review is intended to serve the scientific community for research, development and innovation (RDI) purposes, by providing an overview on the current status of the host–guest supramolecular chemistry of nanopesticides, focusing on only the two-dimensional (2D), brucite-like inorganic layered hydroxides, layered hydroxide salts and layered double hydroxides as the functional nanocarriers or as the hosts in smart nanodelivery systems of pesticides for plant protection. Zinc layered hydroxides and zinc/aluminum-layered double hydroxides were found to be the most popular choices of hosts, presumably due to their relative ease to prepare and cheap cost. Other hosts including Mg/Al-, Co/Cr-, Mg/Fe-, Mg/Al/Fe-, Zn/Cr- and Zn/Cu-LDHs were also used. This review also covers various pesticides which were used as the guest active agents using supramolecular host–guest chemistry to combat various pests for plant protection. This looks towards a new generation of agrochemicals, “agro-nanochemicals”, which are more effective, and friendly to life, humans and the environment.

“…Sulpha drug based Schiff base ligands have been synthesized as per reported method [33][34] . In this method, we have used a 100 mL neat and clean round bottom flask, 5 mL of alcoholic solution of anisaldehyde (1.22 mL, 0.01mol) was mixed with hot absolute ethanol-acetone solution of sulphacetamide (1.24 g, 0.01 mol) / sulphadiazine (2.50 g, 0.01mol)/ sulphamethazine (2.7 g, 0.01mol) / sulphamerazine (2.64 g, 0.01mol) in 1:1 molar ratio.…”

In this study, we report synthesis, characterization and biological activities of four sulpha drug based Schiff base ligands and their Sn(II) complexes. The Schiff bases and their Sn(II) complexes have been synthesized by traditional methods and characterized by the spectral techniques IR, NMR (1H and 13C), mass and TGA-DTA. Newly synthesized Schiff bases (L1-L4) and their Sn(II) complexes (C-1 to C-4) have been screened for antibacterial activity against bacterial strains S. aureus, S. pyogenus, E. coli, P. aeruginosa and antifungal activity against fungal strains C. albicans, A. niger, A. clavatus using broth micro dilution method. Best antimicrobial activity was shown by C-3 complex against E. coli (MIC, 50.0 µg/mL) and A. niger microbial strains (MIC, 100 µg/mL). Moreover, antimalarial activity against plasmodium falciparum was also studied. Complex C-3 was found to be more active against parasite P. falciparum (IC50, 0.04 µg/mL). Results showed that dichloride tin complexes are more active with respect to their corresponding Schiff base ligands.
