  • Publication number: 20250072285
    Abstract: A light emitting element that may include a first electrode, a second electrode provided on the first electrode, and an emission layer provided between the first electrode and the second electrode is provided. The emission layer includes a first polycyclic compound and may also include second to fourth compounds. The polycyclic compound has a pentacyclic core including aromatic groups fused to heteroatoms and has a sterically-bulky, first substituent linked to the core. Steric bulk of the polycyclic compound may increase intermolecular distances and prevent or reduce intermolecular interactions that could impede multi-resonance characteristics of the pentacyclic core.

  • Publication number: 20080057085
    Abstract: Malaria in humans is caused by infection with Plasmodium species parasites including P. vivax. The biology and immunobilogy of P. vivax is distinct from that of P. falciparum. Provided are unique synthetic polypeptides and DNA molecules which encode them. Each of these molecules correspond to regions of the circumsporozoite protein of P. vivax. Each molecule comprises sequences corresponding to several repeats of the central region of the Pv 210 variant fused to sequences corresponding to several repeats of the central region of the Pv 247 variant. Each molecule additionally comprises sequences corresponding to either the amino terminus, the carboxy terminus, or both the amino and carboxy termini of the PvCSP. Also provided are vaccines comprising these unique sequences and methods of using these vaccines and sequences to prevent and treat Pv malaria.

  • Publication number: 20060153881
    Abstract: Compositions that inhibit the binding of Plasmodium falciparum to erythrocytes include a family of erythrocyte binding proteins (EBPs). The EBPs are paralogues of the P. falciparum binding protein EBA-175. The present invention includes peptides of the paralogues that prevent the binding of P. falciparum. Antibodies specific for each paralogue that also prevent the binding of P. falciparum are also included. Methods of the invention utilize the paralogues, antibodies thereof and peptide compositions for the diagnosis, prevention, and treatment of P. falciparum diseases such as malaria, as well as methods for the detection of P. falciparum in biological samples and culture media.
