Abstract: The present invention is related to the development of novel compounds and methods for the treatment and/or prevention of malaria. The compounds prevent the formation by the malaria parasite of the plasmodium surface anion channel (PSAC) on the surface of the host cell. The compounds and methods described herein are effective against infection by a wide variety of Plasmodia strains known as the causative agent of malaria.

Abstract: The present invention is related to the development of therapeutics and prophylactics for the treatment and/or prevention of bacterial infections in humans and other mammals. A new class of small molecules is disclosed that inhibits the bacterial trans-translation/ribosome rescue mechanism and thus blocks infection of host cells by bacteria. Also disclosed are methods of using the small molecule inhibitors in the treatment/prevention of bacterial infections.

Abstract: The present invention is related to the development of therapeutics and prophylactics for the treatment and/or prevention of filovirus infection in humans and other mammals. A new class of small molecules is disclosed that inhibits the interaction of naturally processed (i.e., proteolytically cleaved) filovirus glycoprotein (GPCL) with its host receptor Niemann-Pick C1 (NPC1) protein and thus block infection of host cells by filoviruses. Also disclosed are methods of using the small molecule inhibitors in the treatment/prevention of filovirus infection.

Abstract: The present invention is related to the development of compounds and methods for inhibiting viral infection in a mammal. A pseudotype virus was developed for use in a high throughput assay for identifying nonpeptidic small molecule inhibitors that prevent viral entry into a host cell.

Abstract: Organic compounds showing the ability to inhibit viral glycoprotein (GP)-mediated entry of a filovirus into a host cell are disclosed. The disclosed filovirus entry inhibitor compounds are useful for treating, preventing, or reducing the spread of infections by filovirus including the type species Marburg virus (MARV) and Ebola virus (EBOV). Preferred inhibitors of the invention provide therapeutic agents for combating the Ivory Coast, Sudan, Zaire, Bundibugyo, and Reston Ebola virus strains.

Abstract: A Raman scattering spectrographic analyzer wherein a microscope objective is adapted to view single bio-specimens on a substrate having monodispersed-sized metal particles. A defined wavelength of radiation is applied through the microscope and returning radiation resulting from Raman scattering by bio-specimens is applied to a spectrometer operative to provide a signal corresponding to the wavelength components in said Raman scattered or shifted radiation. The spread spectrum of the Raman shift is analyzed for identification of a bio-specimen.
