摘要:
The present invention relates to selective inhibitors of phosphoinositide (PI) 3-kinase β, use of the selective inhibitors in anti-thrombotic therapy, and a method for screening compounds useful for the new anti-thrombotic therapy by detecting selective inhibitory activity of PI 3-kinase β of the compound. The invention also relates to novel compounds that are inhibitors of PI 3-kinase.
摘要:
Morpholino-substituted pyridopyrimidine, quinolone, and benzopyranone derivatives inhibit phosphoinositide (PI) 3-kinase, an enzyme that regulates platelet-adhesion processes. As a consequence, the compounds in question have anti-thrombotic activity, as well as other pharmaceutical properties. The compounds claimed are represented by formula (I), (II) and (III). PI 3-kinase generates 3-phosphorylated PI second messengers which stimulate platelet adhesion under blood-flow conditions. Because platelet adhesion is a necessary step in the formation of a thrombus, inhibition by these compounds of PI 3-kinase under such conditions inhibits or prevents thrombus formation. The compounds are useful in treating PI 3-kinase-dependent conditions including cardiovascular diseases such as coronary artery occlusion, stroke, acute coronary syndrome, acute myocardial infarction, vascular restenosis, atherosclerosis, and unstable angina; respiratory diseases such as asthma, chronic obstructive pulmonary diseases (COPD), and bronchitis; inflammatory disorders, neoplasms including cancers such as glioma, prostate cancer, small cell lung cancer, and breast cancer, and diseases linked to disordered white blood cell function, such as autoimmune and inflammatory diseases.

摘要:
This invention relates to a purification method, particularly for purifying tyrosine kinase receptor related polypeptides, and to products made by the method. The method comprises a method of producing tyrosine kinase receptor-related polypeptides, the method comprising expressing a tyrosine kinase receptor-related polypeptide in a recombinant expression system and separating expressed monomeric tyrosine kinase receptor-related polypeptide from multimeric form(s) of the expressed polypeptide in a separation step, the separation step allowing refolding of the expressed tyrosine kinase receptor-related polypeptide into a biologically active form.
摘要:
An apparatus, system, and method are disclosed for generating a reproducible virtual environment in a computer software program. This invention describes a method of generating a realistic virtual environment dependent on a sequence of pseudo-random numbers generated by a pseudo-random number generator initialized by a seed value that may be created by the user. If a user starts with the same initial seed, the same virtual environment is created each time the program is run. However, if a new seed is used, a new virtual environment will be created.

摘要:
Novel phosphotetrahydropyran compounds that mimic mannose-6-phosphate but that are more resistant to phosphatases and mannosidases, and pharmaceutical compositions thereof, are disclosed. These compounds and compositions inhibit T lymphocyte migration from blood to tissues or to other extravascular sites. By inhibiting such migration, these compounds are useful for treating diseases or disorders that are mediated at least in part by such T lymphocyte migration. Such diseases and disorders include rheumatoid arthritis, multiple sclerosis, acute disseminated encephalomyelitis, psoriasis, inflammatory bowel disease, T cell-mediated dermatitis, stromal keratitis, uveitis, thyroiditis, sialitis and type I diabetes.

摘要:
An attachment for cooperation with an associated electric switch mounting box and an associated faceplate which includes an elongated bolt; a plurality of beads, each having an internal bore dimensioned for allowing passage of an axial portion of the elongated bolt, and first and second finish washers, the beads being disposed on the elongated bolt when each of the beads being disposed in adjacent relationship to at least one other of the beads, the plurality of beads comprising an elongated stack, the first and second finish washers being disposed respectively at the axial extremities of the stack. In some forms of the invention the finish washers have cupped peripheral edges which may be disposed in facing relationship whereby the axial extremities of the stack have smooth surfaces. The beads may have respective colors associated with a country. The colors may be red, white and blue. Other forms of the apparatus include an electric switch mounting box having at least one threaded bore therein; a faceplate dimensioned and configured for mounting on the electric switch mounting box; an elongated bolt dimensioned and configured for passing through the faceplate into the threaded bore; a plurality of beads, each having an internal bore dimensioned for allowing passage of an axial portion of the elongated bolt; and first and second finish washers.
