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,
分别通过亲核置换和一锅多组分反应合成了新型的β-芳氧基喹啉3a - i及其吡喃并[3,2- c ]色烯衍生物6a - r,其中包含已验证的分子靶标。研究了合成化合物对代表性的致病菌株的体外抗菌活性,这些致病菌株特别是枯草芽孢杆菌,破伤风梭菌,肺炎链球菌,大肠杆菌,伤寒沙门氏菌,霍乱弧菌,烟曲霉和白色念珠菌。化合物3c,3e,3g,6f,6l和6q显示出优异的抗菌活性,而化合物6p显示出比一线标准药物更强的抗真菌活性。评估了针对结核分枝杆菌H37Rv的体外抗结核活性,化合物6f成为具有更好抗结核活性的有希望的抗微生物成员。该化合物的大多数似乎是更好的抗菌剂,但抗结核药效果较差。

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

New Schiff's base derivatives 5a-j have been synthesized by reaction between 2-phenoxyquinoline-3-carbaldehydes 3a-j and 2-(2-methyl-5-nitro-1H-imidazol-1-yl)acetohydrazide 4 in presence of nickel(II) nitrate as a catalyst in ethanol under reflux in good yield (78-92%). All compounds were tested for anticancer and inhibition of EGFR. Of the compounds studied, majority of the compounds showed effective antiproliferation and inhibition of EGFR and HER-2 activities. Compound 5h showed most effective inhibition (IC50 = 0.12 +/- 0.05 mu M) by binding in to the active pocket of EGFR receptor with minimum binding energy (Delta G(b) = -58.3691 kcal/mol). The binding was stabilized by two hydrogen bonds, two pi-cation and one pi-sigma interactions. Compound 5d showed most effective inhibition (IC50 = 0.37 +/- 0.04 mu M). (c) 2014 Elsevier Ltd.
