摘要:
A 3-dimensional PDMS cell sorter having multiple passages in a PDMS layer that follow the same path in a DEP separation region and that are in fluid communication with each other within that region. The passages may differ in width transverse to the flow direction within the passages. Flat plates may sandwich the PDMS layer; each plate may have a planar electrode used to generate a DEP field within a sample fluid flowed within the passages. The DEP field may concentrate target cells or particulates within one of the passages within the DEP separation region. The passages may diverge after the DEP-separation region, leaving one passage with a high concentration of target cells or particulates. Techniques for manufacturing such structures, as well as other micro-fluidic structures, are also provided.

The disclosure generally relates to a process for the preparation of compounds of formula (I), including synthetic intermediates which are useful in the process.
摘要:
A process is provided for preparing spiro-hydantoin compounds of the formula (II), wherein Z is N or CR 4b ; K and L are independently O or S; Ar is an optionally substituted aryl or heteroaryl; A 2 is a linker, G' is a linker; Q is a linker; and R 2 , R 4a , R 4c , and R h are defined in the specification. The process optionally includes the enantiomeric separation of intermediates to allow preparation of enantiomers of the spiro-hydantoin compounds of formula II. Substituted spiro-hydantoin compounds may be prepared from the spiro-hydantoin compounds of formula (II). The spiro-hydantoin compound of formula (II) and the substituted spiro-hydantoin compounds are useful in the treatment of immune or inflammatory diseases. Also, provided are products made by the instant inventive process and crystalline forms (prepared by any process) of the substituted spiro-hydantoin compound, 5-[(5 S , 9 R )-9-(4-Cyanophenyl)-3-(3,5-dichlorophenyl)-1-methyl-2,4-dioxo-1,3,7-triazaspiro[4.4]non-7-ylmethyl]-thiophene-3- carboxylic acid, including solvates and salts thereof, as well as methods of use thereof. Crystalline forms of certain intermediates are provided.
