These Schiff bases have been then reacted with chloroacetyl chloride to get corresponding azetidinones (SMB-2a to SMB-9a). The structures of all these compounds have been established on the basis of analytical and spectral data. Compounds SMB-1, SMB-2 and SMB-6 are comparable with standard drug ampicillin against S. aureus and S. epidermidis. Compounds SMB-1, SMB-2, SMB-6 and SMB-6a are comparable with ampicillin against E. coli and K. pneumoniae. Compounds SMB-1 and SMB-6 show good activity as compared to standard drug micanazole nitrate against C. albicans and SMB-1 activity is comparable with micanazole nitrate against A. niger. <br/> <br/>Page(s): 884-887 Sat, 28 Apr 2007 22:58:59 GMT http://nopr.niscair.res.in/handle/123456789/628 Title: Synthesis and bioactivity of some new [3-[4-methylphenoxymethyl]- 4-phenyl-[1,2,4] triazole-5-thio]acetanilide derivatives <br/> <br/>Authors: Wei, Tai-Bao; Tang, Jing; Liu, Hong; Zhang, You-Ming <br/> <br/>Abstract: The synthesis of some triazole derivatives starting from 4-methyl-phenoloxyacetyl hydrazide is described. In this process, the method for the synthesis of 2-chloroacetanilide had been improved and good yields have been obtained. The chemical structure of all compounds have been elucidated by IR, ¹H NMR, ¹³C NMR and elemental analysis studies. All of the compounds have been investigated for plant growth regulating activity. It had been found that they remarkably enhance root elongation. <br/> <br/>Page(s): 880-883 Sat, 28 Apr 2007 22:58:59 GMT http://nopr.niscair.res.in/handle/123456789/626 Title: Synthesis and fungicidal activity of some 3-(5-aryl-1,3,4-thiadiazol-2-yl)-1- (β-D-glucopyranosyl)-5-alkyl- 2-thio-4-imidazolidinones <br/> <br/>Authors: Srivastava, Alok Kumar; Khare, R K; Singh, H <br/> <br/>Abstract: 3-(5-Aryl-1,3,4-thiadiazol-2-yl)-1-(-β-D-glucopyranosyl)-5-alkyl-2-thio-4-imidazolidinones 5 have been conveniently prepared from 3-(5-aryl-1,3,4-thiadiazol-2-yl)-5-alkyl-2-thio-4-imidazolidinones 3 by reaction of β-D-1,2,3,4,6-penta-O-acetylglucopyranose and iodine. Compounds 3 are synthesized by reported method from N-(5-aryl-1,3,4-thiadiazol-2-yl) thioureas 2 and ⍺-chloroalkanoic acid in dry pyridine. All the compounds have been tested in vitro for their antifungal activity against the two fungal species Cephalosporium sacchari, Colletotrichum falcate and Helminthosporium oryzae. <br/> <br/>Page(s): 875-879 Sat, 28 Apr 2007 22:58:59 GMT http://nopr.niscair.res.in/handle/123456789/624 Title: A new flavone glycoside from Zanthoxylum acanthopodium DC <br/> <br/>Authors: Babu, B Ravindra; Khurana, Shilpi; Sakhuja, Rajeev; Srivastava, Amit K; Jain, Subhash C <br/> <br/>Abstract: Examination of the dry fruits of Zanthoxylum acanthopodium has led to the isolation of a new flavone glycoside along with herbacetin-8,4'-dimethyl ether. The new flavone glycoside is characterized as 7-O-⍺-D-glucosyl-3,8-dihydroxy-2-(3-hydroxy-4-methoxyphenyl)-5-methoxy-4H-1-benzopyran-4-one on the basis of its spectral studies and that of its aglycone. This is the first report of the isolation of a 5-O-substituted flavone from the genus Zanthoxylum. <br/> <br/>Page(s): 872-874 Sat, 28 Apr 2007 22:58:59 GMT
