compounds. They exhibit antianaphylactic, oral hypotensive and antiulcer properties. 2-Benzoxepine moiety is present in many useful neuroleptic (pinoxepin), antidepressant (spiroxepin) and anti-inflammatory agents (isoxepac and oxepinac). The synthesis of 2-benzoxepines having different functionalities is thus necessary. As a part of our program related to the discovery of novel bioactive compo...

Most research has investigated floral nectar as a source of carbohydrates for mosquitoes and has ignored homopteran honeydew. We have assessed the prevalence of honeydew and nectar feeding in 7 species of mosquitoes collected from Algonquin Provincial Park, Ontario, Canada. In total, 403 individuals were analyzed by thin-layer chromatography, with melezitose and stachyose as honeydew-indicator ...

Postsynaptic differentiation of dendrites is an essential step in synapse formation. We report here a requirement for the transcription factor myocyte enhancer factor 2A (MEF2A) in the morphogenesis of postsynaptic granule neuron dendritic claws in the cerebellar cortex. A transcriptional repressor form of MEF2A that is sumoylated at lysine-403 promoted dendritic claw differentiation. Activity-...

A large tryptic peptide of bovine serum albumin (residues 377--582) was subjected to 32 cycles of Edman degradation to determine the sequence of the last remaining unknown segment of this protein. Residues 400--403 were identified as gly-Phe-Gln-Asn. Amide assignments were also made at positions 388 (glutamine), 389 (asparagine), 391 (aspartic acid) and 392 (glutamine).

The mutant 572-403 of Bacillus brevis Vm4 was isolated from N-methyl-N'-nitro-N-nitroso guanidine (nitrosoguanidine)-treated cultures of the parental strain. The mutant produces tatumine and edeine B when grown in a defined medium at 40 degrees C. Tatumine is composed of spermidine, glycine, isoserine, and an unidentified ninhydrin-positive compound; it has a molecular weight of less than 730 d...
