Abstract: The present invention relates to a class of small molecule hydroxamic acid compounds capable of inhibiting histone deacetylases (HDACs). The present invention also relates to methods of preparation of hydroxamic acid HDAC inhibitor compounds of the invention, which are N-substituted-1,2,3,4-tetrahydroisoquinoline hydroxamic acid derivatives, and their incorporation into pharmaceutical compositions and methods of administration. The present invention also relates to N-substituted-1,2,3,4-tetrahydroisoquinoline hydroxamic acid derivatives, which may be prepared as a hydroxamic acid HDAC inhibitor compound library that can be utilized in screening methods known in the art.

Abstract: A multiple channel high throughput purification system for purifying a plurality of samples, preferably four or more samples from a chemical library. The high throughput purification uses chromatography, and more preferably, super critical fluid chromatography. Four parallel channels are provided in this system and coupled to a common analyzer and computer. The four channels direct the selected sample flow through a separator, such as an SFC column, a detector, such as a UV detector, to detect peaks within the sample flow, and a micro sample valve that splits a sampling of the flow to an analyzer, such as a mass spectrometer. The system also utilizes unique back pressure regulator assemblies and pressure relief assemblies to maintain a selected pressure within the purification channel. While the sample flow continues, the mass spectrometer simultaneously analyzes the sampling to determine if a target compound is within the sample portion.
