Abstract: Methods for production of chirally pure .alpha.-amino acids and N-sulfonyl .alpha.-amino acids are described. An aldehyde and a cyanide salt are reacte d with an .alpha.-methylbenzylamine to afford a product. The product reacts wi th a strong acid, is neutralized, and is extracted. The resulting product is subsequently hydrogenated and hydrolyzed to provide a product which is dissolved in a strong acid to provide a salt of a chirally pure .alpha.-amin o acid, which is reacted to provide the chirally pure .alpha.-amino acid. Another method involves mixing ephedrine hemihydrate and an N-sulfonyl .alph a.- ethylnorvaline in ethanol at a molar ratio of 1:1; heating the mixture to dissolve the solids; cooling to allow formation of a precipitate; washing wi th an organic solvent to give diastereomeric salt; recrystallizing the salt; dissolving the recrystallized salt in an organic solvent and strong aqueous acid, separating the layers; washing the organic extract; drying and concentrating to provide chirally pure N-sulfonyl .alpha.-amino acid.</SDOAB >

Patent CA-2479263-A1 (CA)
Inventor: CALLAWAY DAVID J E
IPC: A61K31/473
Filed: 2002-12-20
Abstract: Described is a new class of small molecule inhibitors of amyloid .beta. protein (A.beta.) aggregation, based on apomorphine. These molecules target the nucleation phase of A.beta. self-assembly and interfere effectively with aggregation of A.beta. 1-40 into amyloid fibrils invitro as determined by transmission electron microscopy, Thioflavin T (ThT) fluorescence, and velocity sedimentation. Structure-activity studies using apomorphine analogu es demonstrate that 10, 11-dihydroxy substitutions of the D ring are preferred for the inhibitory effectiveness of these aporphines, and that methylation o f these hydroxyl groups reduces their inhibitory potency. The ability of these small molecules to inhibit A.beta. amyloid fibril formation appears to be linked to their ability to undergo auto-oxidation in solution, implicating a n auto-oxidation product as the active A.beta., inhibitor. Sedimentation velocity and electron microscopy studies demonstrate that apomorphine and analogues facilitate oligomerization of A.beta. into short nonfibrillar soluble assemblies, but inhibit A.beta. fibrilization.

IPC: G01D3/02
Filed: 2003-05-13
Abstract: A method, apparatus and system are disclosed for general use and for specific use when measuring pressure in well bores of hydrocarbon wells. A sensor, an interferometric optical pressure transducer (22), is disposed at the end if a fibre optic line (20) and illuminated by broadband light pulses from a pulsed broadband light source (10). Measuring equipment is provided, in the form of reflectors (31) and filters (34A, 34B, 34C) producing modulated and temporally separate light pulses (36, 38, 40, 36A, 38A, 40A) which are measured by a common photodiode (30), whose output is supplied to a microprocessor (56) driving a display (60) which indicates the pressure applied to the sensor (22). The transducer (22) is mathematically modelled by subjecting the transducer (22) to known pressures and noting the outputs. The measuring equipment (30-34) is mathematically modelled by applying test signals and noting the response for each signal. The mathematical models are combined (with individual device compensating factors). A microprocessor (56) output (C) is assumed. A mathematical model is used to calculate an estimation (B) of the actual output (A) from the sensor. (B) is compared with (A) and the value of (C) changed in the appropriate direction until the closest match is found between (A) and (B). The value of (C), at the closest approach between (A) and (B), is taken as the output to represent the pressure observed at the sensor (22). Different models and compensation factors can be used to allow interchange of different sensors and sensor types and measuring equipment and measuring equipment types.
