Abstract:
A method is disclosed for preparing hydrazides from hydrazine and an acyl chloride which comprises the steps of (a) preparing a stirred substantially uniform slurry comprising hydrazine and an inert solvent at low temperature; and (b) adding an acyl chloride continuously to said slurry. The method avoids or limits production of undesired bis-hydrazide by-products. The method is used to prepare 3-methyl-3-mercaptobutanoic acid hydrazide, a molecule used to link calicheamicin to a monoclonal antibody.
Abstract:
The present invention provides binding proteins and antigen-binding fragments thereof, including human antibodies, that specifically bind to the human interleukin-21 receptor (IL-21R), and methods of using them. The binding proteins can act as, e.g., antagonists of IL-21R activity, thereby modulating immune responses in general, and those mediated by IL-21R in particular. The disclosed compositions and methods may be used, e.g., in diagnosing, treating, and/or preventing IL-21R-associated disorders, e.g., inflammatory disorders, autoimmune diseases, allergies, transplant rejection, and other immune system disorders.
Abstract:
The disclosure provides novel antibodies against growth and differentiation factor-8 (GDF-8), including antibody fragments, which inhibit GDF-8 activity in vitro and in vivo. The disclosure also provides methods for diagnosing, preventing, or treating degenerative disorders of muscle, bone, or insulin metabolism.
Abstract:
Disclosed are compounds which bind VLA-4. Certain of these compounds also inhibit leukocyte adhesion and, in particular, leukocyte adhesion mediated by VLA-4. Such compounds are useful in the treatment of inflammatory diseases in a mammalian patient, e.g., human, such as asthma, Alzheimer's disease, atherosclerosis, AIDS dementia, diabetes, inflammatory bowel disease, rheumatoid arthritis, tissue transplantation, tumor metastasis and myocardial ischemia. The compounds can also be administered for the treatment of inflammatory brain diseases such as multiple sclerosis.
Abstract:
The present application provides human antibodies and antigen binding fragments thereof that specifically bind to the human interleukin-21 receptor (IL-21R). The antibodies can act as antagonists of IL-21R activity, thereby modulating immune responses in general, and those mediated by IL-21R in particular. The disclosed compositions and methods may be used for example, in diagnosing, treating or preventing inflammatory disorders, autoimmune diseases, allergies, transplant rejection, cancer, and other immune system disorders.
Abstract:
Methods for preparing cyclic carbamates and thiocarbamates containing cyanopyrrole moieties and of the formula are provided: Z are the same or different and are H, optionally substituted C1 to C6 alkyl, or CORA; RA is H, optionally substituted C1 to C6 alkyl, optionally substituted C1 to C6 alkoxy, or optionally substituted C1 to C6 aminoalkyl; Q are the same or different and are H, OH, NH2, CN, halogen, optionally substituted C1 to C6 alkyl, optionally substituted C2 to C6 alkenyl, optionally substituted C1 to C6 alkynyl, optionally substituted C1 to C6 alkoxy, optionally substituted C1 to C6 aminoalkyl, or CORB; and RB is H, optionally substituted C1 to C6 alkyl, optionally substituted C1 to C6 alkoxy, or optionally substituted C1 to C6 aminoalkyl. Compounds including 2-amino-5-(5-cyano-1-methyl-1H-pyrrol-2-yl) benzoicacid methyl ester, 5-[4-amino-3-(1-hydroxy-1-methyl-ethyl)-phenyl]-1-methyl-1H-pyrrole-2-carbonitrile, and 2-amino-5-(5-cyano-1-methyl-1H-pyrrol-2-yl)-phenyl-ethanone, or pharmaceutically acceptable salts thereof, and the uses thereof are also provided.
Abstract:
The invention relates to thienopyrimidine and pyrazolopyrimidine compounds of the Formulas (Ia) and (IIa), or a pharmaceutically acceptable salt thereof, wherein the constituent variables are as defined herein compositions comprising the compounds, and methods for making and using the compounds.
Abstract:
An improved system for large scale production of glycoproteins in cell culture is provided. In accordance with the present invention, cells expressing a glycoprotein are grown in media that contain manganese at a concentration of between approximately 10 and 600 nM. The use of such a system allows production of a glycoprotein with an increased glycosylation pattern and/or a glycosylation pattern that more accurately reflects the glycosylation pattern of the naturally occurring glycoprotein. A glycoprotein expressed in accordance with the present invention may be advantageously used in the preparation of pharmaceutical compositions.
Abstract:
The invention relates to novel designer osteogenic proteins having altered affinity for a cognate receptor, nucleic acids encoding the same, and methods of use therefor. More preferably, the novel designer osteogenic proteins are designer BMPs and have altered affinity for a cognate BMP receptor. The designer BMPs demonstrate altered biological characteristics and provide potential useful novel therapeutics.
Abstract:
Tanaproget polymorph Form II, processes for preparing tanaproget polymorph Form II, pharmaceutical compositions including tanaproget polymorph Form II, micronized tanaproget polymorph Form II, and processes for converting Form II to tanaproget Form I are provided. Also provided are methods of contraception, hormone replacement therapy, stimulation of food intake and treating or preventing uterine myometrial fibroids, benign prostatic hypertrophy, benign and malignant neoplastic disease, dysfunctional bleeding, uterine leiomyomata, endometriosis, polycystic ovary syndrome, or carcinomas and adenocarcinomas comprising administering polymorph Form II to a mammalian subject.
