摘要:
The present invention is directed to compounds which suppress immune responses and/or selectively inhibit complement. These compounds contain an aromatic ring and are substituted dihydrobenzofurans, spirobenzofuran-2(3H)-cycloalkanes, and their open chain intermediates. The compounds of the present invention, and the pharmaceutically acceptable salts thereof, interrupt the proteolytic processing of C5 to bioactive components, exhibit immunosuppressive activities, and have therapeutic utility in the amelioration of disease and disorders mediated by complement and/or immune activity.
摘要:
The present invention relates to the C3b/C4b receptor (CR1) gene and its encoded protein. The invention further provides for the expression of the CR1 protein and fragments thereof. The genes and proteins of the invention have uses in diagnosis and therapy of disorders involving complement activity, and various immune system or inflammatory disorders. In specific embodiments of the present invention detailed in the examples sections infra, the cloning, nucleotide sequence, and deduced amino acid sequence of a full-length CR1 cDNA and fragments thereof are described. The expression of the CR1 protein and fragments thereof is also described. Also described is the expression of a secreted CR1 molecule lacking a transmembrane region. The secreted CR1 molecule is shown to be useful in reducing damage caused by inflammation and in reducing myocardial infarct size and preventing reperfusion injury.
摘要:
The present invention relates to novel glycoforms and preparations of the soluble complement receptor type 1 (sCR1), and their uses in the therapy of complement mediated diseases and disorders involving inflammation and inappropriate complement activation and in thrombotic or shock state conditions. The invention provides novel glycoforms and methods for producing, detecting, enriching and purifying such glycoforms. The invention further provides methods of specifically producing a glycoform by recombinant or chemical means. Preferred embodiments of the invention include sialylated glycoforms and glycoforms with a pI.ltoreq.5.1 determined by chromatofocusing or with a sialic acid to mannose molar ratio of >0.25. The glycoforms may be formulated alone in therapeutic compositions or in combination with thrombolytic agents.
摘要:
The present invention relates to compositions comprising soluble complement receptor 1 (CR1) and a thrombolytic agent. In a specific embodiment, the thrombolytic agent is anisoylated human plasminogen-streptokinase activator complex (ASPAC). The invention further relates to methods for treating thrombotic conditions in humans and animals by administering a composition comprising soluble CR1 and a thrombolytic agent. In particular, the compositions and methods are useful both for reducing reperfusion injury and ameliorating the other effects of myocardial infarction.
摘要:
Provided are methods of making preparations of recombinant soluble Complement Receptor type 1 (sCR1) defined with respect to the distribution of sCR1 glycoforms and therapeutic methods using them. The preparations are suitable for treatment of allograft or xenograft rejection, diseases involving inflammation or inappropriate complement activation, and thrombotic or shock state conditions. Preferred methods employ sCR1 glycoforms that are sialylated, have a pI of .ltoreq.5.1, or have a sialic acid: mannose molar ratio of .gtoreq.0.25.
