Synthesis and characterization of hydrazone and azine derivatives of bis(cyclopentadienyI) titanium(IV)

Pentacoordinated hydrazone and azine derivatives of bis(cyclopentadienyl)titanium(IV) of the type {equation presented}, have been prepared. The products were characterized by chemical analyses, elec- trical conductance, IR, 1H NMR, and electronic spectral studies. Some hydrazone complexes and a few azine com- plexes of titanium have been studied.' ' However, no systematic study on their organometallic derivatives is available. In view of the versatile chelating ability, widespread applications and lack of data involving organometallic derivatives of titanium, it has been considered of interest to study the reactions of Cp2TiCl2 with the title ligands.

Diazaborines Are a Versatile Platform to Develop ROS-Responsive Antibody Drug Conjugates**

Antibody–drug conjugates (ADCs) are a new class of therapeutics that combine the lethality of potent cytotoxic drugs with the targeting ability of antibodies to selectively deliver drugs to cancer cells. In this study we show for the first time the synthesis of a reactive-oxygen-species (ROS)-responsive ADC (VL-DAB31-SN-38) that is highly selective and cytotoxic to B-cell lymphoma (CLBL-1 cell line, IC50 value of 54.1 nM). The synthesis of this ADC was possible due to the discovery that diazaborines (DABs) are a very effective ROS-responsive unit that are also very stable in buffer and in plasma. DFT calculations performed on this system revealed a favorable energetic profile (ΔGR=?74.3 kcal mol?1) similar to the oxidation mechanism of aromatic boronic acids. DABs’ very fast formation rate and modularity enabled the construction of different ROS-responsive linkers featuring self-immolative modules, bioorthogonal functions, and bioconjugation handles. These structures were used in the site-selective functionalization of a VL antibody domain and in the construction of the homogeneous ADC.

New library of pyrazole–imidazo[1,2-α]pyridine molecular conjugates: Synthesis, antibacterial activity and molecular docking studies

A library of novel pyrazole–imidazo[1,2-α]pyridine scaffolds was designed and synthesized through a one-pot three-component tandem reaction. The structures of synthesized conjugates were confirmed by spectroscopic techniques (NMR, IR and HRMS). In vitro antibacterial evaluation of the twelve synthesized molecules (7a, 8a–k) against methicillin-resistant Staphylococcus aureus and normal strains of Escherichia coli, Salmonella typhimurium, Klebsiella pneumonia and Pseudomonas aeruginosa established 8b, 8d, 8e, 8h and 8i as potent antibacterial agents with superior minimum bactericidal concentration, compared with standard drug ciprofloxacin. Molecular docking studies of all active compounds into the binding site of glucosamine-6-phosphate synthase were further performed in order to have a comprehensive understanding of putative binding modes within the active sites of the receptor.

Ultrasonic assisted synthesis of 2, 3-dihydroquinazolin-4(1H)-ones involving three-component reaction of isatoic anhydride, amines and pyrazole carbaldehydes catalyzed by [?-fe2o3?hap-So3H]

The combination of [?-Fe2O3?HAp-SO3H] as a catalyst and ultrasonic effect catalyzed the synthesis of diverse derivatives of 2, 3-dihydroquinazolin-4(1H)-ones which is reported in this study. The products were synthesized via the one-pot three-component reaction of isatoic anhydride, amines and pyrazole carbaldehydes in water: EtOH catalyzed by recoverable [?-Fe2O3?HAp-SO3H]. This paper conducted an investigation of the effect of various solvents, temperatures and catalysts on the reactions. Short reaction times, mild reaction conditions, simple work-up, the desired yields and the use of an appropriate catalyst are the advantages of this novel method. The new derivatives were validated by using FT-IR,1HNMR, and13CNMR. Moreover, the synthesized compounds were screened for their an-timicrobial activity against bacterial strains.

Synthesis, antiviral, cytotoxicity and antitumor evaluations of A4 type of porphyrin derivatives

This manuscript describes the synthesis of a new series of porphyrin structures 4a-4m, 7, 9, 12 and 14. These structures were investigated against two types of viruses such as HIV-1 and HSV-1. Also they were screened for their antitumor activity. Among all tested compounds, it was found that compound 4b showed a high activity against HIV-1 and HSV-1 and against four different tumor cell lines. Most of the tested compounds showed a moderate degree of a potent antimicrobial activity. The structure of these compounds was confirmed on the basis of their analytical and spectral data such as UV-vis, IR, 13C NMR, 1H NMR spectroscopy and mass spectral data.
