new chemical entities were screened in vitro for their cytotoxic activity towards various tumor cell lines. Of the compounds screened, 6c and 9d exhibited significant activity and the most active analogue 6c displayed promising cytotoxicity against PC-3 (IC50 of 3.12 ± 0.11 μM), DU-145, NCI-H460 and 4 T1 cell lines. Further, 6c and 9d have 2.1 and 1.4 times more aqueous solubility, respectively, than

benzothiazole or quinazolinone moieties are very well-known. Various derivatives of these molecules exhibit remarkable medicinal properties. Based on this fact, the present paper targets for the first time to synthesize a fused molecule containing all these three important heterocyclic units through a three-component one-pot synthesis via cyclocondensation reaction. The molecular iodine catalyzes this

A new class of β-aryloxyquinolines 3a–i and their pyrano[3,2-c]chromenederivatives 6a–r incorporating a validated molecular target has been synthesized via a nucleophilic displacement and a one-pot multicomponent reaction respectively. In vitro antimicrobial activity of the synthesized compounds were investigated against a representative panel of pathogenic strains specifically Bacillus subtilis,

A new series of 4H-chromene derivatives 6a–x bearing 2-aryloxyquinoline nucleus have been synthesized under microwave irradiation by reaction of 2-aryloxyquinoline-3-carbaldehyde 3a–l, malononitrile 4, and compounds (Cyclohexanedione, Dimidone) 5a–b in the presence of NaOH as the basic catalyst. All the compounds were screened against three Gram-positive bacteria (Streptococcus pneumoniae, Clostridium
