A series of novel quinoline derivatives (6-phenyl-6H-chromeno[4,3-b]quinoline) have been prepared by using 4-chloro-2-phenyl-2H-chromene-3-carbaldehyde and various substituted isocyanides as starting materials in the presence of HClO4-SiO2 and Methanol. We screened eighteen compounds of this novel series (6a-r) in six different cancer cell lines (A549 (lung cancer cells), DU145 (prostate cancer cells)
Facile Synthesis of 6-Phenyl-6h-chromeno [4, 3-b] Quinoline Derivatives using NaHSO4@SiO2 Re-usable Catalyst and Their Antibacterial Activity Study Correlated by Molecular Docking Studies
well-known reaction routes like Friedlander synthesis, Niemantowski synthesis and Pfitzinger synthesis. Moreover, polysubstituted quinolones and their derivatives also had shown considerable interest in the fields of organic and pharmaceutical chemistry in recent years. Objectives: The main objective of our research work is towards the design and synthesis of divergent biological-oriented, proactive

synthesize other valuable heterocycles is described. These carbaldehydes are obtained in excellent yields through the Vilsmeyer-Haack reaction of flavanones and azaflavanones. Protocols towards the synthesis of new heterocycles, such as 3H-chromeno[3–c]quinolines, (Z/E)-2-aryl-4-chloro-3-styryl-2H-chromenes, and (E)-2-aryl-4-chloro-3-styrylquinoline-1(2H)-carbaldehydes were established. Altogether, we

new series of 1,4-diaryl-1,4-dihydrochromeno[4,3-c]pyrazoles have been synthesised. The target compounds and their analogues (2,4-diaryl-2,4-dihydrochromeno[4,3-c]pyrazoles) were tested for their antitumour activities in vitro against MCF-7 and HL-60 cells using the MTT method. Among these compounds, 1,4-bis(4-chlorophenyl)-1,4-dihydrochromeno[4,3-c]pyrazole was found to have potent antitumour activity
