Abstract
The establishment of facile synthetic routes to engineer covalent organic frameworks (COFs) with fully conjugated structure and excellent stability is highly desired for practical applications in optoelectronics and photocatalysis. Herein, a novel linkage conversion strategy is reported to prepare crystalline thiadiazole-linked COFs via thionation, cyclization, and oxidation of N-acylhydrazole bonds with Lawesson's reagent (LR). The as-prepared thiadiazole-linked COFs not only remain porosity and crystallinity, but enhance its chemical stability. Furthermore, thiadiazole-linked COFs are more favorable to lower exciton binding energy and promote π-electron delocalization over the whole reticular framework than N-acylhydrazone-linked COFs. Notably, the extended π-conjugation structure and decent crystallinity of the resulting TDA-COF are reflected by its higher photocatalytic H2 evolution rate (61.3 mmol g-1 in 5 h) in comparison with that (7.5 mmol g-1 ) of NAH-COF.

Abstract
Triazole ring is a cyclic scaffold containing three heteroatoms of nitrogen. They display a broad variety of biological activities. The uncatalyzed/catalyzed 1,3-dipolar cycloadditions are a chemical reaction between a 1,3-dipole and a dipolarophile to achieve 1,2,3-triazoles. The hybrid approach is an innovative and powerful synthetic tool for the synthesis of two or more distinct entities in one molecule with novel biological activities. Owing to the high potential of β-lactams to display noticeable biological properties, these compounds have been one of the important ingredients in hybrid molecules. The four-membered lactams have been recognized as a part of penicillin. There are various synthetic protocols for the synthesis of β-lactams. Staudinger reaction of the Schiff bases with diphenylketenes is a successful and famous strategy for the synthesis of these products. Even though, the number of heterocyclic compounds is limited, plenty of hybrids based on heterocyclic compounds can be designed and prepared. The synthesis of hybrid products of triazole-β-lactam has proved to be highly challenging. The current review article outlines the diversity and creativity in the elegant synthesis of triazole-β-lactam hybrids as potential biological agents. Molecules including isatin, ferrocene, bile acid, chalcone, and etc were attached to β-lactam with triazole linker, as well.

Abstract
DNA-encoded combinatorial chemical library (DEL) technology, an approach that combines the power of genetics and chemistry, has emerged as an invaluable tool in drug discovery. Skeletal diversity plays a fundamental importance in DEL applications, and relies heavily on novel DNA-compatible chemical reactions. We report herein a phylogenic chemical transformation strategy using DNA-conjugated benzoyl hydrazine as a common versatile precursor in azole chemical expansion of DELs. DNA-compatible reactions deriving from the common benzoyl hydrazine precursor showed excellent functional group tolerance with exceptional efficiency in the synthesis of various azoles, including oxadiazoles, thiadiazoles, and triazoles, under mild reaction conditions. The phylogenic chemical transformation strategy provides DELs a facile way to expand into various unique chemical spaces with privileged scaffolds and pharmacophores.

Abstract
Schiff bases from 2-aminoanthraquinone have been prepared by reaction with aldehydes and used to prepare novel β-lactam-anthraquinone hybrids via [2+2] ketene-imine cycloaddition (Staudinger reaction) reaction. In vitro antibacterial studies of all synthesized compound were carried out against three gram-positive strains Staphylococcus aureus (Methicillin-resistant strain), Enterococcus faecium (Vancomycin-resistant strain) and Bacillus subtilis, and two gram-negative strains Escherichia coli and Pseudomonas aeruginosa. These compounds were further evaluated for their in vitro antifungal activity against Candida albicans, Aspergillus niger and Trichophyton mentagrophytes. Hybrid compounds showed moderate to excellent antibacterial and antifungal activities. Surprisingly, among the tested compounds, some of them revealed equal antibacterial and antifungal properties and even better than standards. In addition, results demonstrated that the new hybrids are very promising antibacterial agents against resistant strains. Also molecular docking studies were carried out by Autodoc software. Penicillin-binding protein 2a (PDB ID: 1VQQ) from methicillin-resistant Staphylococcus aureus strain used as a target which good binding interactions were observed.

Abstract
Benzohydrazide derivatives 1-43 were synthesized via "one-pot" reaction and structural characterization of these synthetic derivatives was carried out by different spectroscopic techniques such as 1H NMR and EI-MS. The synthetic molecules were evaluated for their in vitro urease inhibitory activity. All synthetic derivatives showed good inhibitory activities in the range of (IC50 = 0.87 ± 0.31-19.0 ± 0.25 µM) as compared to the standard thiourea (IC50 = 21.25 ± 0.15 µM), except seven compounds 17, 18, 23, 24, 29, 30, and 41 which were found to be inactive. The most active compound of the series was compound 36 (IC50 = 0.87 ± 0.31 μM) having two chloro groups at meta positions of ring A and methoxy group at para position of ring B. The structure-activity relationship (SAR) of the active compounds was established on the basis of different substituents and their positions in the molecules. Kinetic studies of the active compounds revealed that compounds can inhibit enzyme via competitive and noncompetitive modes. In silico study was also performed to understand the binding interactions of the molecules (ligand) with the active site of enzyme.
