Pantoea ananatis is a bacterium associated with other microorganisms on Abutilon theophrasti Medik. roots. It converts 6-hydroxybenzoxazolin-2(3H)-one (BOA-6-OH), a hydroxylated derivative of the allelochemical benzoxazolin-2(3H)-one, into 6-hydroxy-5-nitrobenzo[d]oxazol-2(3H)-one. The compound was identified by NMR and mass spectrometric methods. In vitro synthesis succeeded with Pantoea prote...

Copper (II) phthalocyanine and 2,9,16,23 tetrakis nitro copper (II) phthalocyaninehas been synthesized respectively from phthalonitrile and 4-nitro phthalonitrile under solvent-free condition using two different catalystsovernanodimensionalzeolites. 4-Nitro phthalonitrile synthesized from phthalimide in three steps. The newly prepared compounds have been characterized by IR, UV-Vis, 1</sup...

a series of five-membered heterocyclic rings were synthesized by the reaction between benzoyl chloride and various chlolro-nitro-benzoyl chlorides and semi carbazide to form (c1-c7) compounds and was tested for their anti-inflammatory activity determined by rat-paw-oedema method. all the synthesis compounds have been characterized by 1hnmr, ir and mass spectral data. the compounds were purified...

UNLABELLED The International Diabetes Federation reported that 246 million adults worldwide had diabetes mellitus and the prevalence of this syndrome was expected to increase continuously. AIM To design new compound with potential antidiabetic and antioxidant activity. MATERIAL AND METHODS New benzylidene-thiazolidine derivatives (BT2a-2e) were obtained by condensation of xanthine-thiazolid...

Lung cancer caused by polycyclic aromatic hydrocarbons (PAHs), nitro-PAHs and related environmental agents is a major problem in industrialized nations. The high case-fatality rate of the disease, even with the best supportive treatment, underscores the importance of primary lung cancer prevention. Development of biomarkers of exposure and effects to PAHs and related compounds is now underway a...
