Abstract:
An automated method for remote computing of molecular docking & dynamics from one or more jobs in a network of plurality of users is disclosed herein. The invention additionally employs a system to execute the said method comprising at least one user device, a remote computing server and a remote database. The job defining action tags are received and scanned by the remote server. A semantic analysis is performed on the jobs to distinguish between customized and non-customized tasks. A data analysis of the said jobs is packaged in a compressed format. The user is continually updated of the job status. A public link is generated and sent to the user to download the results. The link is disabled after the downloading of the results to ensure the security of the data. The method avoids any duplication of jobs and can be performed even when the user is offline.
Abstract:
Methods and systems for drug discovery collaboration provide collaborative drug discovery electronic workplaces simultaneously accessible by multiple user computing devices. In certain embodiments, a server computer running a server side application communicates with multiple user computing devices. The server side application communicates with electronic databases that define the parameters of each electronic workplace. Each workplace includes an indication of one or more items, such as compounds, and data pertaining to such items, such as computational and experimental data. Updates to a workplace made by one user may be saved to the workplace definition and propagated and displayed to other users. New items of interest may be added to a workplace. A new item added to a workplace may also be saved to the database and registered with the system for use by other users and in connection with other workplaces.

Abstract:
Drug discovery is a complex undertaking facing many challenges, not the least of which is a high attrition rate as many promising candidates prove ineffective or toxic in the clinic owing to a poor understanding of the diseases, and thus the biological systems, they target. Therefore, it is broadly agreed that to increase the productivity of drug discovery one needs a far deeper understanding of the molecular mechanisms of diseases, taking into account the full biological context of the drug target and moving beyond individual genes and proteins. The present methods rely on the use of label-free cellular assays, particularly the DMR index, to systematically display the mode of actions, the toxicity, and the target(s) and pathway(s) of any molecules.

Abstract:
A system and method to search spectra databases and to identify unknown materials. A library having a plurality of sublibraries is provided wherein each sublibrary contains a plurality of reference data sets generated by a corresponding one of a plurality of spectroscopic data generating instruments associated with the sublibrary. Each reference data set characterizes a corresponding known material. A plurality of test data sets is provided that is characteristic of an unknown material, wherein each test data set is generated by one or more of the plurality of spectroscopic data generating instalments. For each test data set, each sublibrary is searched where the sublibrary is associated with the spectroscopic data generating instrument used to generate the test data set
Abstract:
Data that represents chemical structures, and fragments thereof, are transformed into corresponding molecular keywords comprising letters and numbers that are associated with the original data representation. These molecular keywords encode the structural features of a given chemical structure. Molecular keywords are generated for linear structures, branching points, adjacent branching points, monocyclic, polycyclic and macrocyclic ring systems, stereo centers, ring-substituent patterns and molecular-formula atom counts. Indexing, database searching, and Web page presentation can be provided in conjunction with the molecular keywords representation.
Abstract:
A stochastic algorithm has been developed for predicting the drug-likeness of molecules. It is based on optimization of ranges for a set of descriptors. Lipinski's "rule-of-5", which takes into account molecular weight, logP, and the number of hydrogen bond donor and acceptor groups for determining bioavailability, was previously unable to distinguish between drugs and non-drugs with its original set of ranges. The present invention demonstrates the predictive power of the stochastic approach to differentiate between drugs and non-drugs using only the same four descriptors of Lipinski, but modifying their ranges. However, there are better sets of 4 descriptors to differentiate between drugs and non-drugs, as many other sets of descriptors were obtained by the stochastic algorithm with more predictive power to differentiate between databases (drugs and non-drugs). A set of optimized ranges constitutes a "filter". In addition to the "best" filter, additional filters (composed of different sets of descriptors) are used that allow a new definition of "drug-like" character by combining them into a "drug like index" or DLI. In addition to producing a DLI (drug-like index), which permits discrimination between populations of drug-like and non-drug-like molecules, the present invention may be extended to be combined with other known drug screening or optimizing methods, including but not limited to, high-throughput screening, combinatorial chemistry, scaffold prioritization and docking.
Abstract:
Modeling systems are enhanced by combining physical and virtual modeling techniques to create a hybrid modeling system. Manipulation of physical models results in updated realtime physical characteristics being provided to a virtual model. User manipulation of virtual model characteristics can also be provided and implemented on the physical model using actuators and control devices. The invention also enables multiple users to simultaneously construct and manipulate different portions of a physical model, e.g., of an atom or a molecule, and to have the results of these manipulations provided to a computer system for computational analysis. The results of such analyses can be electronically returned to the physical model, e.g., wirelessly.
