“…SHA and hexa coordinated in ArTeCl. (SHA) 2 The MIC data reveal that the aryltellurium(IV) hydroxamate complexes and potassium hydroxamate possess more biocidal activity than the precursor salicylhydroxamaic acid 22 , which shows MIC in the range 66-88 µg/mL.…”

p-methoxyphenyl, p-hydroxyphenyl, 3-methyl-4-hydroxyphenyl; SHA = salicylhydroxamate) have been synthesized by reactions of aryltellurium(IV) trichlorides and diaryltellurium(IV) dichlorides with potassium salicylhydroxamate. The aryltellurium(IV) hydroxamates have been characterized on the basis of elemental analyses, conductance measurements in DMSO, infrared and proton magnetic resonance studies. The spectral studies conjointly predicts the bidentate (O, O′) nature of hydroxamates to yield the penta and hexacoordinated tellurium complexes. The biological activities of these complexes were evaluated against some pathogenic bacteria and fungi organisms.

“…Oxazalones exhibited promising photo physical and photochemical activities [19], so they are used in semiconductor devices such as electro photographic photoreceptors and in non-linear optical materials [20]. Oxazalones has cyclooxygenase-2 inhibitory property [21] and tyrosine's inhibitory property. 17 AG 50 Peptaibol, endothiopeptides, and 24-membered cyclic dipsipeptide were formed by "azirine/oxazalones" method which incorporate the Alb (α-aminoisobutyric) acid units for cyclization of the linear peptides [22][23][24].…”

Seven 4-arylbenzelidene-2-((5-fluoro-1H-indol-1-yl)methyl)oxazol-5(4H)-one derivatives were synthesized by the condensation of 2-(2-(5-fluoro-1H-indol-1-yl) acetoamide) acetic acid, substituted aromatic aldehydes with acetic anhydride and sodium acetate in the presence of MgO/Al2O3 under reflux using nickel ferrite nanoparticles. Seven of the compounds are new derivatives. 2-(2-(5-fluoro-1H-indol-1-yl)acetoamide) acetic acid was obtained from 2-(5-fluoro-1H-indol-1-yl)acetyl chloride with lysine in the presence of NaOH and HCl in the ice cold solution. 2-(5-fluoro-1H-indol-1-yl)acetyl chloride can be prepared from 5-fluoro indole with chloroacetyl chloride in triethylamine and dichloromethane. The structures of the compounds were evaluated based on 1 H-NMR, 13 C-NMR and LC-MS and by elemental analysis. These compounds were screened by antioxidant as well as anti-microbial activity.

“…Benzo[b]pyrans have a broad spectrum of biological properties and it is well known structural scaffold of several natural products and artificial drugs [7]. These are used for antibacterial and anti-fungal activity [8], anticancer activity [9], insecticidal activity [10], antimicrobial [11] and anti-inflammatory agent [12], antioxidant [13], anti-anaphylactic and diuretic agent.…”

ABSTRACT. An efficient and convenient procedure has been described for one-pot multi-component synthesis of tetrahydrobenzo [b]pyrans known as 2-amino-7,7-dimethyl-5-oxo-4-phenyl-5,6,7,8-tetrahydro-4H-chromene-3-carbonitrile which can be obtained from the reaction of substituted aromatic aldehydes, dimedone, malonitrile, in the presence of base such as potassium tertiary butoxide and THF in methanol as solvent at RT condition. All the compounds were examined by advanced spectroscopic data ( 1 H NMR, 13 C NMR and LCMS) and the structural determination was evaluated by elemental analysis. In addition to this, all the newly synthesized compounds were examined for their antibacterial activities and antifungal activity by disc diffusion method against the organism of Aspergillus niger and Candida ablicans L.
