Abstract:
The present invention relates to methods and compositions for treating cancers with extracts of Ganoderma lucidum (Reishi or Ling-Zhi). Methods for treating tumor progression and metastasis by modulating epithelial-mesenchymal transition (EMT) are provided. Methods for reducing migration and invasion of cancer cells are provided. Alkaline extracts of Ganoderma lucidum comprising immune-modulating activity for modulating EMT and inhibiting progression of cancers are provided.
Abstract:
The crystal structure at 2.16 A resolution of the full-length bacterial bifunctional transglycosylase penicillin-binding protein Ib (PBPIb) from Escherichia coli, in complex with its inhibitor moenomycin, is provided. The atomic coordinates of the complex as well as the moenomycin binding site are provided. Three dimensional structures of amino acid residues involved in moenomycin binding and transglycosylation activity are identified. Binding site for peptidoglycan synthesis inhibitors comprising inhibitor- binding site comprises amino acid residues from at least one of transglycosylase (TG), UvrB domain 2 homolog (UB2H) and transmembrane (TM) domains of PBPIb are identified at an atomic level of resolution. Methods for rational drug design based on the atomic coordinates are provided. Methods for screening for antibiotics based on anisotropic binding assay and transglycosylase inhibitor assays are provided. Novel antibiotics based on the screening assays of the invention are disclosed.
Abstract:
The present disclosure relates to synthetic alpha-galactosyl ceramide (a- GalCer) analogs, and their use as immunotherapies, adjuvants, and antiviral, antibacterial, and anticancer agents. In one aspect, a method of activating a cytokine response in a subject includes administering an effective amount of a compound to a subject, wherein the subject has an adaptive immune system that includes a population of cells, the population including at least one lymphocyte and at least one antigen-presenting cell, and wherein the compound is represented by the structure of formula 1 :; or a pharmaceutically acceptable salt thereof; forming a complex between the compound and the antigen-presenting cell, wherein the formation of the complex results in the activation of a receptor on the lymphocyte; and activating the lymphocyte to produce the cytokine response.
Abstract:
A composition of acetic acid and a composition of acetic acid and RF3 effecting expression of DAF-16 in C. elegans, wherein the at least acetic acid and the RF3 polysaccharide is effective to increase the life-span of C. elegans or humans. A method of regulating DAF-16 expression, comprising: administering a composition comprising at least acetic acid and RF3 polysaccharide; providing the composition to at least one receptor on a surface of a cell; causing an increase in expression of DAF-16. A method for screening a series of compounds or constituents parts of compounds including some antioxidant vitamins, traditional herb medicines, and vinegars using C. elegans as a live organism model to examine to determine if they have an impact the lifespan of C elegans and the underlying mechanism(s) thereof.
Abstract:
Novel 5-membered iminocyclitol derivatives were found to be a potent and selective inhibitors of the glycoprotein processing a-and ß-glucosidase which were further found to be active antiviral agents against Japanese encephalitis virus, dengue virus serotype 2 (DEN-2), human SARS coronavirus and human ß-hexosaminidase, a new target for development of osteoarthritis therapeutics.
