Abstract: The present disclosure describes compounds of the following formula in which: the groups A, which may be identical or different, represent a group n is an integer equal to 1 or 2, Y represents an oxygen or sulfur atom, a methylene, hydroxymethylene, carbonyl or thiocarbonyl group, or a group of formula the groups R, which may be identical or different, represent a hydrogen, an alkyl, alkylamine, hydroxyl-alkyl or alkyloxy chain containing from 1 to 6 carbons, or a —COOH, —CONH2, —COOR2 or —CONHR2 group in which R2 is an alkyl chain containing from 1 to 6 carbons, or, when the substituents R are identical in the 2-pyridinyl groups, the substituents R2 may together form an ethereal cyclic alkyl chain, with the exception of the compounds: 2,6-di[5-(2-pyridyl)pyrrol-2-yl]pyridine and bis[5-(6-methyl-2-pyridyl)pyrrol-2-yl]methane.

Abstract: A lead-frame circuit package comprises a die and a substrate located thereon to route radio frequency signals to/from the die. The package preferably comprises an exposed pad on the die to receive a power amplifier device wherein the substrate is used to provide high-Q elements such as RF chokes on signal paths to/from the power amplifier device. In this manner, the design benefits from the power capabilities and improved grounding of a lead-frame conductor, whilst also achieving the routeing capabilities and small scale advantages provided by a multi-layer printed circuit substrate.

Abstract: The present invention relates to methods and compositions for preventing or treating diseases of a mammal, including viral infections, wherein at least one symptom of the disease is mediated at least in part by the binding of an effector molecule to a DC-SIGN receptor present on cells of the mammal to be treated. The invention also provides methods of identifying compositions, wherein the compositions are useful for treating mammalian diseases, including viral infections, for which at least one symptom of the disease is mediated at least in part by the specific binding of an effector molecule to a DC-SIGN receptor present on the cells that express the DC-SIGN receptor, belonging to the mammal to be treated. The invention further relates to compositions and methods for targeting subject molecules to cells that express the DC-SIGN receptor.
