Patent number: 6344334Abstract: Method for identifying a drug lead compound that inhibits binding of target bioogical molecules (TBM) by contacting TBM with members of a library of candidate cross-linked target binding fragments (CXBF), each CXBF having at least two candidate target bindig fragments (CTBF), which are inhibitors of binding, linked to a cross-linker, and selecting CXBF that inhibit the binding of the TBM to a greater extent than either of the individual CTBF linked to said cross-linker, wherein the library of CXBF is produced by: (a) screening a population of CTBF capable of being chemically cross-linked by a cross-linker to identify a subpopulation of the CTBF that inhibit binding of the TBM; and (b) chemically cross-linking members of the subpopulation of CTBF or structurally related analogs thereof with a cross-linker to provide a library of CXBF, wherein at least one linking group comprises an oxime ether linking group.Type: GrantFiled: March 26, 1999Date of Patent: February 5, 2002Assignee: The Regents of the University of CaliforniaInventors: Jonathan A.

Patent number: 6323384Abstract: This invention provides a process to convert linear alkenes such as butene-1 and butene-2 to methyl branched chain alkenes such as isobutylene using the hydrogen form of ferrierite. The hydrogen form of ferrierite has a pore size which allows the branched chain alkenes to form and diffuse out of the catalyst while reducing the formation of unwanted by-products, including dimers, trimers, aromatics and coke. This invention has been demonstrated with H-ferrierite in a laboratory scale reactor. Selectivities approaching 100% were demonstrated for isobutylene formation using H-ferrierite.Type: GrantFiled: June 5, 1991Date of Patent: November 27, 2001Assignee: Equistar Chemicals, LPInventors: Donald H.
