molecules, because blocking fucosylation will allow glycosidase-catalyzed hydrolysis of the labeled oligosaccharide to produce a fluorescent signal. Employing this assay, we have screened a focused library of small molecules for inhibitors of a human FUT enzyme involved in the synthesis of sialyl LewisX and demonstrated that our approach can be used to identify potent FUT inhibitors from compound libraries
DESIGN, SYNTHESIS AND ANTIBACTERIAL EVALUATION OF 1-[(1R,2S)-2-FLUOROCYCLOPROPYL] CIPROFLOXACIN-(4-METHYL-3-ARYL)-1,2,4-TRIAZOLE-5(4H)-THIONE HYBRIDS

Fourteen novel 1-[(1R,2S)-2-Fluorocyclopropyl]ciprofloxac in-(4-methyl-3-aryl)-1,2,4-triazole-5(4H)-thionehybrids 6a-n were designed, synthesized and assessed for their in vitro antibacterial activities against representative Gram-positive and Gram-negative bacteria. All hybrids 6a-n exhibited promising antibacterial activity, especially against Gram-negative pathogens, warrant further investigation
from the reaction of acid hydrazide 1 with alkyl or aryl isothiocyanate 2 in the presence of a KOH (10%) solution on the surface of silica gel as well as on the surface of montmorillonite K10 undermicrowaveirradiation. These triazoles have also been prepared from the reaction of 4-substituted-1-aroyl thiosemicarbazides 3a–e, with a KOH (10%) solution on the surface of silica gel undermicrowave irradiation

prepared and evaluated for potentialantidepressant activity. Members of this series were generally prepared by the alkaline ring closures of the corresponding 1-aroylthiosemicarbazides. Several members of this series were potent antagonists of both RO 4-1284-induced hypothermia and reserpine-induced ptosis in mice. In general the more active members of this series were substituted by haloaryl groups at
