Investigating the Antiproliferative Activity of Novel 4-Chloro-8-Nitro-1,2-Dihydro-3-Quinoline Acylhydrazones on Human Cervical Cancer Cell Lines.

A new series of acyl hydrazones have been synthesized from 4-chloro-8-nitro-1,2-dihydroquinoline-3-carbaldehyde. These compounds were characterized using various spectroscopic techniques. Density functional theoretical (DFT) studies were conducted to understand the correlation between electronic parameters and biological activity.

()-5-(4-Methyl-benzyl-idene)-1-phenyl-4,5,6,7-tetra-hydro-1-indazol-4-one.

In the title compound, CHNO, the non-aromatic six-membered ring adopts a distorted envelope conformation with one of the methyl-ene-C atoms being the flap atom. The dihedral angle between the phenyl and 4-tolyl rings is 75.3 (1)°.

()-5-(4-Chloro-benzyl-idene)-1-phenyl-4,5,6,7-tetra-hydro-1-indazol-4-one: crystal structure and Hirshfeld surface analysis.

In the title compound, CHClNO, the non-aromatic six-membered ring adopts a distorted envelope conformation with methyl-ene-C atom nearest to the five-membered ring being the flap atom. The dihedral angle between the phenyl and chloro-benzene rings is 74.5 (1)°.

Spectro-electrochemical, fluorometric and biothermodynamic evaluation of pharmacologically active morpholine scaffold single crystal ligand and its metal(II) complexes: A comparative study on in-vitro and in-silico screening towards DNA/BSA/SARS-CoV-19.

A novel series of metal(II) complexes (1-5) [M(L)]{Where M = Cu (1), Co (2), Mn (3), Ni (4) and Zn (5)} constructed from 2-(4-morpholinobenzylideneamino)phenol Schiff base ligand (HL) in a 1:2 M ratio and the spectral and analytical results put forward square planar geometry. Spectro-electrochemical, hydrodynamic, gel electrophoresis, and DNA binding/cleavage results for all the compounds demonstrate that complex (1) had excellent DNA binding/cleavage properties compared to other compounds. The observation also suggests that test compounds could intercalate with DNA, and the biothermodynamic property more strongly supports the stabilizing of the double helix DNA with the complexes.

Cesium-Fluoride-Promoted Synthesis of Stable Organocesium Reagents and Their Ambident Reactivities with Arynes.

Described are the diverse reactivities of novel, stable, ambident thio-organocesium reagents (bearing electron withdrawing groups) against benzynes. Reactions at reflux temperature predominantly led to the generation of various functionalized stable sulfonium ylides and at 40 °C the same reaction underwent direct c-arylation. Furthermore, lack of internal hydrogen on the cesium reagent helped to produce different ortho-bifunctional arynes in both the reactions.
