摘要:
Novel peptoid oligomers are disclosed that have a formula represented by the following formula I: wherein R1 and n are as described herein. The peptoids demonstrate antimicrobial and antimalarial activity and may be prepared as pharmaceutical compositions and used for the prevention or treatment of a variety of conditions in mammals including humans where microbial or malarial infection is involved. The present cyclic peptoids are particularly valuable as their effect is rapid, broad in spectrum and mostly indifferent to resistance provoked by standard antibiotics.

摘要:
The present invention relates to novel complex peptidomimetic products comprising multiple homogeneous or heterogeneous pendant groups that are site-specifically positioned along a linear oligomer or polymer scaffold and methods of making thereof. More specifically, the invention relates to N-substituted glycine peptoid oligomers or peptoids and their use as substrates for azide-alkyne[3+2]-cycloaddition conjugation reactions and subsequent additional rounds of oligomerization and cycloaddition. The methods of the invention may also be used to generate peptoid-peptide hybrid or peptide products comprising multiple homogeneous or heterogeneous pendant groups, which are positioned precisely along the linear oligomer or polymer scaffold.

Novel peptoids are disclosed that have a formula represented by the following formulae Ia and Ib: wherein X, Y, R, and n are as described herein. The peptoids demonstrate catalytic activity and are useful in substrate-selective catalytic transformations, including asymmetric catalytic transformations.
摘要:
A meringue composition is disclosed, which may be prepared without the inclusion of egg or egg byproduct material as an ingredient. The meringue is prepared from a mixture consisting essentially of saponin, a sugar or sugar substitute, and water. The meringue is capable of being prepared to a self-sustaining, baked product. The final meringue product may be prepared by a variety of heating methods, including microwave heating. Further, the nature of the final product may be controlled by the extent of heating, so that a product more flowable or creamy may be achieved by a reduction in the heating time. The meringue of the invention is suitable for strict vegetarians (‘vegans’) and individuals who are allergic to eggs and egg bi-products.

Novel peptide/peptoid oligomers are disclosed that have a formula represented by the following formula Ia or Ib: The peptide/peptoid oligomers demonstrate the ability to inhibit fibrillization and oligomerization of Aβ and may be prepared as pharmaceutical compositions and used for the prevention or treatment of a variety of conditions in mammals, including humans, associated with Aβ oligomerization. The present peptidomimetic oligomers are particularly valuable for the treatment of subjects with AD.

摘要:
The present invention is directed to a method for synthesizing sequence specific short and long chain length heteropolymers. More specifically, the method is directed to enzyme-mediated ligation of telechelic sequence specific oligomers to generate abiotic linked oligomers and concatenated synthetic oligomers. The invention also encompasses abiotic linked oligomers and abiotic concatenated oligomers comprising greater than 65 monomer units.
摘要:
The invention provides methods of identifying one or more nucleic acids in a sample. The nucleic acids, for example, expressed genes in a cell, can be identified by contacting the nucleic acids with oligonucleotides having detector tags, and selector tags to form tagged oligonucleotides. Each nucleic acid can be uniquely identified by mass-spectrophotometric analysis of the detector tag.
