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.

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.

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.

Animals sense an enormous number of cues in their environments, and, over time, can form learned associations and memories with some of these. The nervous system remarkably maintains the specificity of learning and memory to each of the cues. Here we asked whether the nematode Caenorhabditis elegans adjusts the temporal dynamics of adaptation and aversive learning depending on the specific odor sensed. C. elegans senses a multitude of odors, and adaptation and learned associations to many of these odors requires activity of the cGMP-dependent protein kinase EGL-4 in the AWC sensory neuron. We identified a panel of 17 attractive odors, some of which have not been tested before, and determined that the majority of these odors require the AWC primary sensory neuron for sensation. We then devised a novel assay to assess odor behavior over time for a single population of animals. We used this assay to evaluate the temporal dynamics of adaptation and aversive learning to 13 odors and find that behavior change occurs early in some odors and later in others. Wethen examined EGL- 4 localization in early-trending and late-trending odors over time. We found that the timing of these behavior changes correlated with the timing of nuclear accumulation of EGL-4 in the AWC neuron suggesting that temporal changes in behavior may be mediated by aversive learning mechanisms. We demonstrate that temporal dynamics of adaptation and aversive learning in C. elegans can be used as a model to study the timing of memory formation to different sensory cues.

The electron donor-acceptor molecular complexes between thiazole and some of its derivatives and iodine in several solvents have been investigated spectrophotometrically at different temperatures.Spectral characteristics, equilibrium constants, K, extinction coefficients, epsilon, and thermodynamic functions of formation, DeltaH0, DeltaG0, and DeltaS0 have been determined.It was found that the data fit satisfactorily the 1:1 stoichiometric equilibrium: D + I2 = DI2 “outer complex”.The EDA complexes obtained are of “n – ?*” type in which the nitrogen atom of thiazole is the donor center.Moreover, the effect of solvents on the K values is discussed in terms of the solute-solute and solute-solvent competing equilibria.

A series of bulky amine palladium complexes {[(Ar-NH2)2PdCl2]} were synthesized and characterized. The catalytic activity of the palladium complexes was evaluated via the direct C-H arylation of thiazoles with aryl bromides in aerobic conditions at 80-100 C. Under the optimal conditions, 0.5-0.05 mol% of the bulky palladium complexes were found to be very efficient and produced the desired cross-coupling products in high yields.

Based on the strategy of the development of phosphine-free palladium-catalyzed direct C-H arylation, a series of camphyl-based alpha-diimine palladium complexes bearing sterically bulky substituents were synthesized and characterized. The palladium complexes were applied for the cross-coupling of thiazole derivatives with aryl bromides. The effect of the sterically bulky substituent on the N-aryl moiety as well as the reaction conditions was screened. Under the optimal protocols, a wide range of aryl bromides can be smoothly coupled with thiazoles in good to excellent yields in the presence of a low palladium loading of 0.2 mol% under open-air conditions.
