  • Patent number: 6452050
    Abstract: The invention is based on new methods for making and using compounds and arrays of novel &agr;-ketoamides, and the arrays and compounds made by these methods. These novel compounds are potential inhibitors of proteolytic enzymes, particularly cysteine proteases such as cruzain. Application of the new methods has led to the identification of a number of new inhibitors, from amongst an array of about 38,000 &agr;-ketoamide derivatives, having specific activity against three cysteine proteases: cruzain, papain, and cathepsin B. These compounds and other compounds identified by the methods described herein can be useful, for example, in developing pharmaceutical agents for the treatment of diseases (e.g., Chagas' disease) associated with these proteases. Although the disclosed compounds have specific activity for cruzain, papain, cathepsin B, the methods described herein can also be used to identify inhibitors of other proteases.

  • Publication number: 20020098598
    Abstract: A method for the generation of chemical libraries using machine-readable passive tagging systems is described. The preferred embodiment uses radiofrequency tags or one- or two-dimensional bar codes to track vials and the contents therein throughout the course of the synthesis. This abrogates the need for specialized combinatorial chemistry equipment, allowing the use of standard laboratory baths, ovens, shakers and racks, as well as manual fluid handling techniques.

  • Publication number: 20020068367
    Abstract: A high throughput screening method for detecting interactions between proteins, nucleic acids and small molecules comprising coating a solid support surface with a substance, such as streptavidin, that has a high affinity for a ligand, such as biotin, that may be readily attached to a library of compounds via a linker molecule. The biotin linked library members are spotted onto the stretpavidin in a pattern and screened for binding to other compounds of interest. Thus, it is possible to screen much smaller quantities of compounds than would be possible in a multiwell format. Due to the high affinity of biotin for streptavidin, there is no diffusion of the compounds on the solid support. Moreover, the method provides a high throughput, low cost screen that may be accomplished completely manually without the use of expensive fluid handling robots.

  • Patent number: 6358750
    Abstract: The invention provides spiro[pyrrolidine-2,3′-oxindole] compounds and libraries of these compounds produced by the stereo- and regio-selective reaction of variously substituted isatins, &agr;-amino acids, and dipolarophiles (e.g., trans-chalcones, acrylate esters, or vinyl oxindoles). The new libraries can be assayed using any of many known screening procedures for activity, e.g., biological activity. For example, the libraries can be screened for activity as drugs (e.g., anticancer drugs, antibiotics, antiviral drugs, antiinflammatory drugs, analgesics, immunomodulators, neuroleptics, sedatives, stimulants, or diagnostic aids), bioseparation agents, or pesticides (e.g., herbicides, insecticides, or rodenticides).
