The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.78364-55-3, Name is 6-Fluoro-2-hydrazinylbenzo[d]thiazole, molecular formula is C7H6FN3S. In a Article£¬once mentioned of 78364-55-3, SDS of cas: 78364-55-3

The triazole analogs were obtained via. multistep synthesis sequence beginning with ethyl nicotinoate 3 which on treatment with hydrazine hydrate yields nicotinoyl hydrazide 4. Intermolecular cyclisation of 4 with 4-methylbenzoic acid in presence of phosphorous oxy chloride affords 2-(3-pyridyl)-5-(4-methylphenyl)-1,3,4-oxadiazole 5. Condensation of 5 with various substituted 2-hydrazino benzothiazole 2a-j results in 3-(3-pyridyl)-5-(4-methylphenyl)-4-(N-substituted-1,3-benzothiazol-2-amino) -4H-1,2,4-triazole 6a-j analogs. All the compounds have been characterized by elemental analysis, IR, 1H NMR, 13C NMR and mass spectral data. In vitro antitubercular activity was carried out against Mycobacterium tuberculosis H37Rv strain using Lowenstein-Jensen medium and antimicrobial activity against various bacteria and fungi using broth microdilution method. Compounds 2e, 6a, 6b, 6c, 6d, 6g, 6h and 6i emerged as promising antimicrobials. It was also observed that the promising antimicrobials have proved to be better antituberculars. Compound 6j showed better antitubercular activity compared to rifampicin. 3-(3-Pyridyl)-5-(4-methylphenyl) -4-(N-substituted-1,3-benzothiazol-2-amino)-4H-1,2,4-triazole 6a-j were synthesized and their antitubercular activity against H37Rv and antimicrobial activities have been tested.

Tsetse flies transmit trypanosomiasis to humans and livestock across much of sub-Saharan Africa. Tsetse are attracted by olfactory cues emanating from their hosts. However, remarkably little is known about the cellular basis of olfaction in tsetse. We have carried out a systematic physiological analysis of the Glossina morsitans antenna. We identify 7 functional classes of olfactory sensilla that respond to human or animal odorants, CO2, sex and alarm pheromones, or other odorants known to attract or repel tsetse. Sensilla differ in their response spectra, show both excitatory and inhibitory responses, and exhibit different response dynamics to different odor stimuli. We find striking differences between the functional organization of the tsetse fly antenna and that of the fruit fly Drosophila melanogaster. One morphological type of sensilla has a different function in the 2 species: Trichoid sensilla respond to pheromones in Drosophila but respond to a wide diversity of compounds in G. morsitans. In contrast to Drosophila, all tested G. morsitans sensilla that show excitatory responses are excited by one odorant, 1-octen-3-ol, which is contained in host emanations. The response profiles of some classes of sensilla are distinct but strongly correlated, unlike the organization described in the Drosophila antenna. Taken together, this study defines elements that likely mediate the attraction of tsetse to its hosts and that might be manipulated as a means of controlling the fly and the diseases it transmits.

A tomato essence was developed for potential flavor enhancement of juices and other tomato products. The changes in the flavor profile that occur during tomato processing in plum tomatoes were characterized and compared using purge and trap gas chromatography-mass spectrometry (PT-GC?MS). The pilot tomato juices mostly suffered losses in green and fruity note-related compounds. Of the four essence fractions produced, Fractions 1 and 2 were most complementary to the undesirable flavor changes encountered during thermal processing. Fraction 1 was characterized as a ?green tomato note?, with substantially higher amounts of 2-isobutylthiazole, alpha-citral, hexanal, 3-hexen-1-ol, and 6-methyl-5-hepten-2-one; Fraction 2 was described as a ?fruity tomato note? with relatively percentage change of compounds; and Fractions 3 and 4 were described as ?cooked tomato note? and ?faint tomato note?, respectively. These results demonstrate the feasibility of adding tomato essence to impart desirable flavor attributes to processed tomato products.

A series of aryl phosphoglyceride (3, 19-61) and bis-aryl phosphate (67-135) antagonists of platelet activating factor (PAF) were prepared.A group of four bifunctional phosphorus reagents (5a-c and 7) were developed that allowed the preparation of these aryl phosphates in which the position of aromatic substitution can be varied.These compounds were examined for their ability to inhibit PAF-induced platelet aggregation of rabbit platelets.Selected compounds were also evaluated for their ability to displace <3H>PAF from its receptor on rabbit platelets.These in vitro data were compared to similar data obtained for a number of known PAF antagonists.The compounds were evaluated in vivo, in both the mouse and rabbit, for their ability to prevent death induced by a lethal challenge of PAF.The relationships between the biological activity and the nature, lipophilicity, and position of substituents of the aromatic rings were studied.Compound 105 (CL 184005) has been selected to undergo further development as a potential therapeutic agent for the treatment of septic shock in man.

The iodine charge transfer complexes of thiazole, 4-methylthiazole, 2,4-dimethylthiazole, and benzothiazole in carbon tetrachloride have been studied by the constant activity method.The equilibrium characteristics of the CT complexes formed were measured.It was concluded that the CT complexes are of the n-?* nature and the donating site for the charge transfer interaction is the lone pair of electrons on the nitrogen atom.Moreover, the effect of substitution on the CT equilibrium was also studied.The equilibrium constants have been found to be satisfactorily correlated with the pK values of the respective thiazole derivatives.This can be attributed to the lone pair of electrons on nitrogen being more localized on increasing the donating power of substituent.Hence, the electron density on the nitrogen atom increases and an increase in equilibrium constant was seen.
