Combinatorial libraries are disclosed which are represented by Formula I: ##STR1## wherein: ##STR2## is a solid support; T'--L-- is an identifier residue; and --L'--II' is a ligand/linker residue. These libraries contain dihydrobenzopyrans of the formula ##STR3## which interact (i.e., as agonists or antagonists) with .alpha. adrenergic receptors, dopamine receptors, .sigma.-opiate receptors, and K.sup.+ channels and are inhibitors of carbonic anhydrase isozymes. They are useful in the treatment ...

A method for producing arrays by spacing a dispenser a distance from a surface of a support, dispensing a volume containing a compound in a single coupling step of less than 5 nl to occupy a localized area of less than 1 cm.sup.2 of the surface of the support, allowing the compound to bind directly or indirectly to the support and repeating the steps to produce an array of at least 100 ligands at a density of 1000 per cm.sup.2 or greater.

Methods and apparatus for the preparation and use of a substrate having an array of diverse materials in predefined regions thereon. A substrate having an array of diverse materials thereon is generally prepared by delivering components of materials to predefined regions on a substrate, and simultaneously reacting the components to form at least two materials. Materials which can be prepared using the methods and apparatus of the present invention include, for example, covalent network solids, i...

A substrate for solid phase synthesis of the formula: ##STR1## is disclosed. Also disclosed are processes for preparing the substrate and intermediates useful therein. Among the novel intermediates are compounds of the formula: ##STR2## wherein t is 0 or 1; n is 3-20; R is OH, an activated ester or the residue of a solid support having a plurality of amino functionalities; A is --O-- or --NH-- and Q is hydrogen or a protecting group for an amine or alcohol.

Combinatorial libraries are disclosed which are represented by Formula I: wherein: S is a solid support; T'--L-- is an identifier residue; and --L'--II' is a ligand/linker residue. These libraries contain dihydrobenzopyrans of the formula: ##STR1## which interact (i.e., as agonists or antagonists) with .alpha. adrenergic receptors, dopamine receptors, .sigma.-opiate receptors, and K.sup.+ channels and are inhibitors of carbonic anhydrase isozymes. They are useful in the treatment of ocular disea...

Disclosed are methods for synthesizing very large collections of diverse thiosaccaride derivatives optionally attached to a solid support. Also disclosed are libraries of diverse thiosaccaride derviatives.

A cassette is provided which includes a combinatorial chemistry dish as used in chemical and biological laboratory work. The cassette includes a metal housing which is adjustable in that it can securely seal a variety of combinatorial dishes having different heights which contain liquid reagents. Planar inner seals placed against the dishes prevent leakage of the reagents while mixing and handling.

Kit, and method for its use and construction, which includes a first plurality of vessels containing different polysubunits, each constructed from a known number of subunits. Each subunit is joined by one or more bonds and each subunit and bond can be the same or different. Each of the different polysubunits has a different sequence of subunits but has the same known subunit at one terminus. Each vessel contains polysubunits which have a different known subunit at one terminus. The kit further i...

A combinatorial weighing method includes reading and storing output data from a plurality of weighing machines, and monitoring the weighing state of each weighing machine at all times on the basis of the stored data. When performing a combinatorial calculation, weight data from weighing machines in a stable state is read and these weight data participate in the combinatorial calculation. A combinatorial weighing apparatus for practicing the foregoing method has a reading circuit for constantly r...

A random combinatorial selection method is disclosed for the construction of oligonucleotide aptamers in which nuclease resistance is conferred by the inclusion of modified nucleotides. The modified nucleotides are incorporated during PCR amplification to form achiral modified oligonucleotides. Thio-substituted aptamers are provided that bind tightly to the nuclear factor for human IL6 (NF-IL6).
