  • Publication number: 20050118636
    Abstract: The invention concerns arrays comprising hundreds, thousands, to hundreds of thousands of samples and methods for screening thereof. These methods are useful to optimize, select, and discover compounds, compositions, or conditions that prevent, inhibit, induce, modify, or reverse physical-state transitions, particularly in-vivo physical-state transitions relating to disease causing processes. Such compounds, compositions, or conditions can be exploited to treat (e.g., reverse) or prevent the disease itself, the cause of the disease, or the symptoms of the disease.

  • Publication number: 20050089923
    Abstract: A method and system for planning and assessing the results of high-throughput solid form screening and high-throughput formulation screening are disclosed. Also disclosed are methods and systems for using high-throughput solid form screening and high-throughput formulation screening to select compounds and formulations for further testing, or to prioritize testing.

  • Publication number: 20040252299
    Abstract: Systems and methods are described that allow the high-throughput preparation, processing, and study of arrays of samples, each of which comprises at least one compound. Particular embodiments of the invention allow a large number of experiments to be performed in parallel on samples that comprised of one or more compounds on the milligram or microgram quantities of compounds. Other embodiments of the invention encompass methods and devices for the rapid screening of the results of such experiments, as well as methods and devices for rapidly determining whether or not similarities exist among groups of samples in an array. Particular embodiments of the invention encompass methods and devices for the high-throughput preparation of different forms of compounds (e.g., different crystalline forms), for the discovery of new forms of old compounds, and for the discovery of new methods of producing such forms.

  • Publication number: 20030162226
    Abstract: The invention concerns arrays of solid-forms of substances, such as compounds and rapid-screening methods therefor to identify solid-forms, particularly of pharmaceuticals, with enhanced properties. Such properties include improved bioavailability, solubility, stability, delivery, and processing and manufacturing characteristics. The invention relates to a practical and cost-effective method to rapidly screen hundreds to thousands of samples in parallel. The invention further provides methods for determining the conditions and/or ranges of conditions required to produce crystals with desired compositions, particle sizes, habits, or polymorphic forms. In a further aspect, the invention provides high-throughput methods to identify sets of conditions and/or combinations of components compatible with particular solid-forms, for example, conditions and/or components that are compatible with advantageous polymorphs of a particular pharmaceutical.

  • Publication number: 20020177167
    Abstract: The present application is directed to the use of computerized data processing to plan, perform, and assess the results of high-throughput screening of multicomponent chemical compositions and solid forms of compounds. Systems utilized include databases of molecular descriptors and related compounds and their properties as determined empirically and through simulation, along with multidimensional visualization tools. Methods include methods for determining chemical compositions by performing steps including selecting a plurality of combinations of values of experimental parameters that can be varied by an automated experiment apparatus, determining a set of experimental results, and determining a second plurality of combinations of values based on the set of experimental results. Additional methods include selecting values of parameters that produce a composition, the values being relatively far from areas of rapid change or boundaries between solid forms.
