Disclosed is a complex of a compound of Formula 1, a stereoisomer thereof, or a tautomer of the compound of Formula 1 or stereoisomer thereof, and a cyclodextrin, in which the complex is an amorphous solid. This disclosure also relates to materials and methods for preparing the complex, to pharmaceutical compositions which contain the complex, and to the use of the complex to treat Type I hypersensitivity reactions, autoimmune diseases, inflammatory disorders, cancer, non-malignant proliferative disorders, and other conditions associated with BTK.

Isoquinolinyl triazolone complexes

A method of producing a chemical compound library comprises extracting at least one extract from at least one species of plant; processing at least one of the extract(s) to remove at least one type of chemical interference to produce a processed extract; chromatographically separating the processed extract into a plurality of chromatographic fractions, each containing an amount of chemical compounds; determining the amount of chemical compounds in at least one of the chromatographic fractions; and normalizing the chromatographic fractions in which the amounts were determined to produce normalized chromatographic fractions, each such fraction comprising from about 1 microgram to about 500 micrograms of each of from one to seven chemical compounds that were present in lower concentrations in the extract and that each have a log P of from about &#x2212;1 to about 5 and a molecular weight less than about 1000 Daltons; thereby to produce a chemical compound library from at least one species of plant.

Screening of chemical compounds purified from biological sources

A method of analyzing each of a plurality of fluid samples (11-16), comprising, simultaneously spraying a plurality fluid samples (11-16) from electrospray needle array (20) towards mass spectrometer (50); positioning blocking device (40) to block all but one (32-34) of fluid samples (31-34) from reaching mass spectrometer (50); moving electrospray needle array (20) and blocking device (40) relative to one another to permit at least two of the plurality of fluid samples (31, 32) to reach mass spectrometer (50) one at a time; and analyzing the mass spectrum of fluid samples (31, 32, 33, 34) sequentially reaching mass spectrometer (50). A system for analyzing the composition of each of a plurality of fluid samples (31-34), comprising, mass spectrometer (50); multi-head electrospray needle array (20) for spraying fluid samples (31-34) towards mass spectrometer (50); and blocking device (40) positioned between electrospray needle array (20) and mass spectrometer (50), blocking device (40) dimensioned to block all but one (32-34) of fluid sample electrosprays (31-34) from reaching mass spectrometer (50).
