    摘要: Compounds, compositions, and methods for inhibiting pulmonary hypertension are disclosed. The invention is particularly directed to the use of agents that specifically inhibit the activity of certain endogenously produced epoxyeicosatrienoic acids that promote vasoconstriction of pulmonary arteries. These agents are particularly useful for inhibiting hypoxia-induced pulmonary hypertension. The invention further discloses additional compounds, compositions and methods for increasing pulmonary hypertension.

    摘要: The invention provides methods and compositions for azide tagging of biomolecules. In one embodiment of the invention, proteins are tagged by metabolic incorporation of prenylated azido-analog substrates. Examples of such analogs are azido famesyl diphosphate and azido famesyl alcohol. The azido moiety in the resulting modified proteins provides an affinity tag, which can be chemoselectively captured by an azide-specific conjugation reaction, such as the Staudinger reaction, using a phosphine capture reagent. When the capture agent is biotinylated, the resulting conjugates can be detected and affinity-purified by streptavidin-linked-HRP and streptavidin-conjugated agarose beads, respectively. The invention allows detection and isolation of proteins with high yield, high specificity, and low contamination without harsh treatment of proteins.
