Samuel Owusu Aboagye June 15, 1985 – October 6, 2019 It is with great sadness that we note the passing of our dear colleague, friend, father, husband, and amazing human Samuel Aboagye unexpectedly a...Read More
The informatics group at the National Center for Advancing Translational Sciences (NCATS) is seeking a creative, self-motivated post-doctoral scientist to work on development of new algorithms for pre...Read More
The NCATS Informatics group is looking for a post-doctoral scientist to work on machine learning methods within Pharos, an interface to the Illuminating the Druggable Genome (IDG) knowledgebase. The...Read More
The NCATS Informatics group is looking for a post-doctoral scientist to work on methodology development for the analysis and visualization of drug combination screening data. Currently, the NCATS Ma...Read More
It's with great sadness that we note the passing our collaborator Eric Dawson. Through the BARD project we got to know Eric as a friendly, engaging and effective collaborator; his enthusiasms and laid...Read More
We have recently developed NCATSFind: a Firefox add-on to help users resolve web content to real chemical structures. The goal is to make discovering, displaying and downloading chemical structures as...Read More
Molecular hash codes are fixed-length alphanumeric encoding of molecular graphs. They play a key role within chemical data management systems in facilitating (among other things) structural identity a...Read More
Molecular scaffold is a fundamental concept in medicinal chemistry. Perhaps nowhere this is more apparent than during early stage discovery, where scaffolds are the primary means by which medicinal ch...Read More
A few years ago we made available our implementation of the PubChem substructure keys fingerprint. Being it was our first attempt, there were a number of shortcomings with the implementation in terms ...Read More
Recently Bruns & Watson published a paper describing a set of rules to filter out (potenially) reactive and promiscuous small molecules. There are 275 rules addressing a variety of possible reason...Read More
Charting, in a technical sense, is the process of mapping objects in high dimensional space to lower dimensional subspace, something which we have previously discussed using the FastMap algorithm. In ...Read More
Update March 2, 2013: The complete code to this tool is available here. Library enumeration and profiling are an integral part of a medicinal chemist's repertoire during early-stage discovery. Whether...Read More
Motivated by the recent renewed interest in substructure searching in the literature, we recently develop a proof-of-concept, self-contained substructure searching engine that can scale to large datab...Read More
To date, the NIH Molecular Libraries Program (MLP)—through its comprehensive and specialized centers—has produced an unprecedented amount of experimental data characterizing various levels of inte...Read More
With the rapid growth of chemical databases such as vendor catalogs and in-house screening collections, the constant desire to improve on (sub-) structure searching performance has never been more jus...Read More
After a somewhat long hiatus (mostly in trying to tie up loose ends for the NPC browser), we're finally back! Motivated by the feedback that we've received from the NPC browser, for the past few weeks...Read More
The paper describing the NCGC pharmaceutical collection (NPC) resource has just been published in the current issue of Science Translational Medicine. Among other things, the paper definitively resolv...Read More
In a recent paper, Metz et al. describe a statistical framework for constructing the kinome polypharmacology network. Using a large kinase panel (i.e., more than 150,000 activity values across 172 kin...Read More
Update Feb. 2, 2013: This Java package is obsoleted; please checkout the latest code here. Recently, we received a request to be able to access to the human kinome dendrogram programmatically. We th...Read More
Update May 29, 2011: Please see this post for the answer to the above question. The NCGC Pharmaceutical Collection (NPC), as we noted earlier, is a result of our ongoing efforts to construct a definit...Read More
