spectrometry. The synthesized compounds showed antibacterialactivity with MBCs in the range 0.80 to 36.49 mM against Staphylococcus aureus, Staphylococcus aureus Rosenbach (MRSA), Pseudomonas aeruginosa, Klebsiella pneumoniae, Escherichia coli and Salmonella typhimurium. The best activity was seen when a larger halogen such as chlorine and bromine were substituted at C-6 on the quinolone scaffold and when

cancers. Inhibition of mutant IDH1 (mIDH1) with small molecules has been clinically validated as a promising therapeutic treatment for acute myeloid leukemia and multiple solid tumors. Herein, we report the discovery and optimization of a series of quinolinones to provide potent and orally bioavailable mIDH1 inhibitors with selectivity over wild-type IDH1. The X-ray structure of an early lead 24 in complex

Acetanilides are converted into 2-chloroquinoline-3-carbaldehydes in good yield by the action of Vilsmeier's reagent in phosphoryl chloride solution. The reaction is shown to involve successive conversion of the acetanilide in to an imidoyl chloride and then an N-(α-chlorovinyl)aniline. The latter enamine is diformylated at its β-position and subsequently cyclised to the chloroquinolinecarbaldehyde

A novel series of quinoline-based symmetrical and unsymmetrical bis-chalcones was synthesized via a Claisen–Schmidt condensation reaction between 3-formyl-quinoline/quinolone derivatives with acetone or arylidene acetones, respectively, by using KOH/MeOH/H2O as a reaction medium. Twelve of the obtained compounds were evaluated for their in vitro cytotoxic activity against 60 different human cancer

Ethyl 3-oxo-3-2-[(5-substituted-3-phenyl-1H-indol-2-yl)carbonyl]hydrazinyl}propanoates 5a—b were synthesized according to the literature method. These on further reaction with substituted-2-hydroxy-3-formylquinolines 3a—e yielded 5-substituted-Nβ-(2-oxo-2H-pyrano[2,3-b]quinoline-3-carbonyl)-3-phenyl-1H-indole-2-carbohydrazides 6a—j. Structures of the all the newly synthesized compounds were confirmed by spectral data. All these compounds have been screened for their antibacterial activity against Staphylococcus aureus, Escherichia coli and Bacillus subtilus, antifungal activity against Aspergillus niger and Candida albicans and antituberculosis activity against Mycobacterium tuberculosis (H37Rv).
