Title: Inhibition of matrix metalloproteases by 2-substituted-4-(4-substitutedphenyl)-4-oxobutyric acids
Inventor: VAN ZANDT MICHAEL C
IPC: C07D253/04
Filed: 1997-05-12
Abstract: Matrix metalloprotease inhibiting compounds, pharmaceutical compositions thereof and a method of disease treatment using such compounds are presented. The compounds of the invention have generalized formula (1) wherein r is 0-2, T is selected from (a) and (b) and R40 is a mono- or bi-heterocyclic structure.      These compounds are useful for inhibiting matrix metalloproteases and, therefore, combating conditions to which MMP's contribute, such as osteoarthritis, rheumatoid arthritis, septic arthritis, periodontal disease, corneal ulceration, proteinuria, aneurysmal aortic disease, dystrophobic epidermolysis, bullosa, conditions leading to inflammatory responses, osteopenias mediated by MMP activity, tempero mandibular joint disease, demyelating diseases of the nervous system, tumor metastasis of degenerative cartilage loss following traumatic joint injury, and coronary thrombosis from athrosclerotic plaque rupture. The present invention also provides pharmaceutical compositions and methods for treating such conditions.
Patent CA-2255131-A1 (CA)
Inventor: CAVANAUGH KEN M
IPC: G06F9/44
Filed: 1998-12-04
Abstract: In order to maintain locking invariants in a multi-threaded system, a special inverse lock class is defined whose constructor stores a reference to, and then releases, a previously-acquired lock whose reference is passed into it. Thedestructor of the class re-acquires the referenced lock. During operation, the class is instantiated, passing in the desired lock before an upcall is made. Instantiation executes the constructor and causes the lock to be released. When the upcall terminates, either normally or by an exception, the inverse lock object destructor is executed causing the lock to be re-acquired. Since the inverse lock object destructor will always be called when the object is destroyed, the locking invariant will always be satisfied.

Patent CA-2264049-A1 (CA)
Inventor: LIN KAUNG-FAR
IPC: C07F5/06
Filed: 1997-08-26
Abstract: Processes are described for the production and use of tri(beta-branched alkyl)aluminum compounds. In a preferred embodiment, a process of this invention involves dimerizing one or more vinylolefin monomers with an alkyl aluminum catalyst to form a first product mixture comprising at least vinylolefin monomer, trialkylaluminum in which each alkyl group has the same number of carbon atoms and skeletal structure as said vinylolefin monomer, and vinylidene olefin. The vinylolefin monomer is then removed while concurrently the trialkylaluminum and vinylidene olefin are converted to tri-(beta-branched alkyl)aluminum by reactive distillation. Reactive distillation effects a shift of the chemical equilibrium away from the trialkylaluminum compound and toward the production of tri-(beta-branched alkyl)aluminum compound. The tri-(beta-branched alkyl)aluminum compound may then be purified by a subsequent distillation, or similarly purified and recycled back into the process as the alkyl aluminum catalyst used in forming the first product mixture. The described processes constitute highly efficient economical processes which may be carried out in a single reactor, if desired, for the high-yield production and use of such compounds.

IPC: H04M3/50
Filed: 1999-06-02
Abstract: System and method for providing a customer with the ability to obtain temporary voicemail service in the Advanced Intelligent Network (AIN) for the customer's calling line by dialing a call to special access code, without the intervention of a service representative. The call is recognized as a request for an initiation of a temporary voicemail service with respect to the customer's calling line. On the basis of the recognition, an association may be retained between the calling line number and the service switching point serving the calling line number.      This retained association may be used later in the activation of the temporary voicemail service for the calling line number. The call is routed to a rental service interface through which rental information from the caller may be collected. This rental information may be compiled into a rental agreement that is used as the basis for activation of the temporary voicemail service with respect to the caller's calling line number. Confirmation of the activation may be provided to the communication.
