abstract the cr(iii) and zn(ii) complexes with 2-((9,10-dihydro-1-hydroxy-9,10-dioxaanthracen-4-yloxy)carbonyl)benzoic acid as ligand have been prepared by reacting cr(no3) and zn(no3)2 and ligand in cloroform. the cr and zn complexes with 2-((9,10-dihydro-1-hydroxy-9,10-dioxaanthracen-4-yloxy)carbonyl) were also prepared in chloroform and aceton solutions. the uv-visible and ft-ir spectra of...
A review of the literature is presented that gives a background to the human sense of smell, then the importance of learnt and innate olfactory cues in animal behaviour. Some possible roles for natural products chemists interested in the interaction between animals and plants are discussed.
Certain peptides such as dynorphin A [dynA-(1-13)] enhance the release of antigenic peptides bound to class II MHC molecules at neutral pH. This enhanced release has been termed push off. Previous work has shown that the antigenic pigeon cytochrome c peptide PCC-(89-104) has at least two conformational isomers when bound to the class II MHC protein I-Ek. We have accordingly studied the push off...
using Vero and RD-18S cells, was unsuccessful. This result is consistent with previous EV-104 reports, wherein the virus could not be grown or isolated (1,2). To determine the presence of other respiratory viruses in this patient, the EV-104–positive specimen was tested by using realtime PCR for any of 17 other viruses (human metapneumovirus, respiratory syncytial virus, human parainfl uenza vi...
