Organotin(IV) complexes are gaining major attention as drug candidates, accordingly we have synthesized a cluster of novel diorganotin(IV) complexes I (R³₂SnClL; R³ = Me, Et, Bu, Ph; R = H, Br; R¹ = H, OH; R² = NO₂, Br) of the corresponding Schiff base ligands (HL¹-HL⁴). The structural elucidation of the compounds was done by using different spectroscopic techniques (UV-Vis, FT-IR, ¹H, ¹³C and ¹¹⁹Sn NMR), mass spectrometry, m.p. and molar conductance measurement. The spectroscopic data recommend that Schiff bases are N,O-bidentate in nature and bind to tin metal via azomethine nitrogen, phenolic oxygen atom and create pentacoordinated environment around central tin metal. To check the biol. utility, the synthesized compounds were tested for antimicrobial activity against different bacterial and fungal strains using serial dilution method and inhibitory activity noted in terms of MIC values (μmol/mL) which displayed that the complexes were more efficient than corresponding Schiff bases and complex 20 (Ph₂SnClL⁴) was most active antimicrobial agent. The compounds were also evaluated for cytotoxic activity against human cancer cell lines- A549 (Lung), PC-3 (Prostate), MDA-MB-231 (Breast), MIA PaCa-2 (pancreas) and human normal cell line fR2 by using MTT method. The results of cytotoxic activity showed that some compounds are active and compounds 10 and 11 (R = H, R¹ = OH, R² = H, R³ = Et, Bu) having IC₅₀ values ranging from 0.01 to 1.42μM are almost equally potent to the standard drug doxorubicin against all examined cell lines and are even less toxic against normal cell line. Diorganotin(IV) complexes of 4-(4-bromophenyl)thiazol-2-amine and salicylaldehyde derivatives were synthesized and exhibited high antibacterial and antitumor activity.

The transition metal complexes of Co(II), Ni(II), Cu(II) and Zn(II) with bidentate Schiff base ligands (HL^1-5) were obtained from condensation of 1,2,3,4-tetrahydro-naphthalen-1-ylamine with methanolic solution of 3-hydroxy-salicylaldehyde, 4-hydroxy-salicylaldehyde, 5-bromo-salicylaldehyde, 3,5-dibromo-salicylaldehyde, and 2-hydroxy-1-naphthaldehyde.

Abstract: In the present research work, four new heterocyclic Schiff base ligands (1–4) were synthesized by the condensation of 4-(4-amino-5-mercapto-4H-1,2,4-triazol-3-yl)phenol with salicylaldehyde derivatives in 1:1 molar ratio. The synthesized Schiff base ligands were allowed for complexation with Co(II), Ni(II), Cu(II), Zn(II) metal ions. The structure of the newly synthesized compounds (1–20) was elucidated with the help of various spectral and physicochem. techniques. Spectroscopic data confirm the tridentate nature of ligands which coordinate to the metal via deprotonated oxygen, azomethine nitrogen and thiol sulfur. Conductivity data showed the non-electrolytic nature of complexes. Furthermore, the synthesized compounds were evaluated for their in-vitro antimicrobial activity against four pathogenic bacterial strains and two pathogenic fungal strains. The observed results of microbial activity reveals that compound 3 and its complexes (13–16) were found most potent against the pathogenic strains. In addition, the anticancer activity of all the synthesized compounds was evaluated against human carcinoma cell lines i.e. HCT-116, DU145 and A549 using MTT assay. Among the tested compounds 12, 19, and 20 show promising potency against the cancer cell lines. To rationalize the preferred modes of interaction of most potent compounds with the active site of human EGFR protein (PDB id: 5XGM), mol. docking studies were performed.

Phototherapy, including photodynamic and photothermal therapies, is a non-invasive photo-triggered tumor treatment. Combination therapy and new synergistic therapeutic reagents may hold promise for improving these treatments. Herein, we report an amphiphilic iridium-based photosensitizer (C14-IP2000) loaded with a hydrophobic photo-thermal drug (ZnPc) to form nano-micelles (ZNPs) for dual-light triggered tumor phototherapy. The C14-IP2000 was contained within ZNPs consisting of an iridium complex core decorated with hydrophilic polyethylene glycol chains to extend the time in blood circulation, and two hydrophobic carbon chains to enhance the loading capacity and the hydrophobic interaction with the loaded reagent. The designed ZNPs showed effective blood circulation, passive tumor targeting ability, remarkable photodynamic conversion ability, and good photothermal conversion capability, and therefore may be used for combined tumor ablation. Our results demonstrated that the amphipathic bionic structure of ZNPs not only enables self-assembled reagent fabrication with prolonged circulation time and favorable metabolic characteristics for tumor combination therapy, but also provides a nanostructure strategy for the modification of functionalized reagents.

Demonti, Luca;Saffon-Merceron, Nathalie;Mezailles, Nicolas;Nebra, Noel research published 《 Cross-Coupling through Ag(I)/Ag(III) Redox Manifold》, the research content is summarized as follows. Trifluoromethyl argentates(III) undergo reductive elimination with arylboronic acids, yielding trifluoromethylarenes. In ample variety of transformations, the presence of silver as an additive or co-catalyst is believed to be innocuous for the efficiency of the operating metal catalyst. Even though Ag additives are required often as coupling partners, oxidants or halide scavengers, its role as a catalytically competent species is widely neglected in cross-coupling reactions. Most likely, this is due to the erroneously assumed incapacity of Ag to undergo 2e^– redox steps. Definite proof is herein provided for the required elementary steps to accomplish the oxidative trifluoromethylation of arenes through Ag^I/Ag^III redox catalysis (i. e. CEL coupling), namely: (i) easy Ag^I/Ag^III 2e^– oxidation mediated by air; (ii) bpy/phen ligation to Ag^III; (iii) boron-to-Ag^III aryl transfer; and (iv) ulterior reductive elimination of benzotrifluorides from an [aryl-Ag^III-CF₃] fragment. More precisely, an ultimate entry and full characterization of organosilver(III) compounds [K]⁺[Ag^III(CF₃)₄]^– (K-1), [(bpy)Ag^III(CF₃)₃] (2) and [(phen)Ag^III(CF₃)₃] (3), is described. The utility of 3 in cross-coupling has been showcased unambiguously, and a large variety of arylboron compounds was trifluoromethylated via [Ag^III(aryl)(CF₃)₃]^– intermediates. This work breaks with old stereotypes and misconceptions regarding the inability of Ag to undergo cross-coupling by itself.

It is an inhibitor of γ-secretase, which is responsible for cleaving the amyloid precursor protein (APP), and it has shown efficacy against biphenyl, an anticancer drug that binds to benzodiazepine receptors. 2-Bromophenylboronic acid is also an enantiopure compound because all four substituents are different from each other., 244205-40-1.

3,5-Dibromosalicylaldehyde reacts with alkyl cyanoacetates in the presence of ammonium acetate to yield 4H- chromenes. 3,5-Dibromosalicylaldehyde can be used in the synthesis of Schiff base and can be used as reactant for synthesis of Schiff base ligands which forms mononuclear complexes with copper(II), nickel(II), zinc(II) and cobalt(II).

3,5-Dibromosalicylaldehyde is a copper complex that has been synthesized from 3,5-dibromosalicylaldehyde and copper chloride. FTIR spectroscopy revealed that the coordination geometry of the copper complex is octahedral with two nitrogen atoms in the equatorial plane. The presence of hydrogen bonding interactions was confirmed by homologous protein adsorption experiments. This chemical structure was determined using X-ray crystallography and fluorescence probe experiments. The copper complex showed high affinity for malonic acid, which is an ester hydrochloride. The molecular mechanism of this interaction is based on adsorption, which occurs through hydrogen bonding interactions and hydrophobic interactions. Structural analysis revealed that the polymeric matrix consists of a three-dimensional network of crosslinked chains, while FTIR analysis indicated a possible disulfide bond between two cysteine residues., 90-59-5.
