As we noted previously, researchers are struggling with a data deluge, and need effective tools to locate, extract, sift and filter relevant data for further detailed visualization and analysis. With biologics, these applications will need to understand and manage bio-sequences, and an immediate requirement will be to allow sequence searching, using a standard tool such as BLAST to search across internal and external sequence collections, to collect and import the appropriate hits in a standard format, and to link them to other pertinent properties bioactivity, toxicity, physicochemical, DMPK, production, etc.
With a tractable data set on hand, researchers will want to explore sequences to try to discern particular motifs or sequence differences that are correlated with bioactivity or desired physicochemical or DMPK profiles, and thus potentially amenable to further manipulation and enhancement.
The sequences must be aligned, for example by CLUSTAL Omega, and visualizations should present sequences so that sequence differences are immediately highlighted, and monomer substitutions can be explored for potential links to bio-therapeutic activity. LOGO plots to investigate the distribution of monomers in a set of sequences, and annotations to highlight and share areas of interest will also help researchers to get to insights more quickly. There may also be cases where required specialized analysis or visualization capabilities are only available in a separate in-house developed, third party, or open-source application, and the provision of an extensible Web Services framework will enable these to be quickly linked in to an enhanced analysis pipeline that can then be shared with colleagues and collaborators.
In a previous post we commiserated with drug discovery scientists and their IT colleagues in their daily struggles to deal with the ever-increasing research data deluge. We then attempted to ease their pain by exploring modern informatics tools and applications that guide them to rapidly and intelligently identify, locate, search, extract and organize tractable sets of relevant data internal or external, structured or unstructured, small molecule or biologic for detailed analysis and visualization.
Drop compounds which have been explored to the point that no further progress seems achievable. An ideal informatics platform should be well aware of these impediments to rapid and incisive data analysis and advanced structure-activity relationship SAR visualization. Instead of daunting the researcher with a potentially overwhelming menu of tools and applications, an effective system should offer a guided pathway embodying scientifically meaningful best practices to select and apply the most appropriate tools and techniques to the active data set.
These advanced visualizations should also be bolstered by a rich set of dynamic charting options, and robust statistical analyses. Data sets can be enriched and explored with more precision if the system can calculate additional physicochemical properties, and then filter and cluster the data based on observed and calculated parameters and structural descriptors to help in identifying promising lead series. Researchers also need to be able to explore and display data at multiple levels within a data hierarchy, from plate to compound level, and compound to chemical series or therapeutic project level for ease of navigation.
Creating a SAR table should be simple and easy with point-and-click configuration.
These advanced chemistry and biologics SAR tools and workflows will be the subject of subsequent blog posts in this series. Modern systems should appeal both to power users, who will want unfettered access to advanced tools, and also to occasional users, who will want to extract immediate value with a minimal learning curve. A productive system should provide ready-to-use templates so that occasional users can immediately start to confidently explore their data, and as groups establish and refine their analysis workflows, these can be captured in shared templates for quick and consistent analyses between collaborating research groups.
Adding an auto-update capability, so that saved queries and filters are automatically re-run as the underlying data is updated, will save time and increase productivity.

Key among these was the challenge of dealing with the data deluge — more complex data at greater volumes, in multiple formats and often stored in disparate internal and external data silos. Typical therapeutic research projects continually generate and amass data — chemical structures; sequences; formulations; primary, secondary, and high-content assay results; observed and predicted physicochemical properties; DMPK study results; instrument data; sample genealogy and provenance; progress reports, etc.
A usual first step will be to collect together all the relevant data and get it into a form that is amenable to further searching and refinement: but this poses a potentially challenging set of questions — what data exists, where is it, what format is it in, and how much of it is there? Answering these questions may then be complicated if the data resides in different, possibly disconnected, potentially legacy systems: e. They will still be likely to get frustrated along the way by things like different query input paradigms e.Here are some of the most recent additions to ChemDraw.

Tuesday, March 18, Automating Chemdraw: win32 com scripting with python pywin Last time I tried, with mixed success. This time, I'm using it to control ChemDraw to help me convert molecule formats. Anytime I use COM scripts, it feels pretty clumsy, like it would be a lot slicker just to have a command line utility, but in this case I couldn't find anything that seemed like it would work well enough update: I later found out about ChemAxon Molconverter which is quite niceso COM scripts it is.
Python is currently the language I do general purpose programming in, and pywin32 works quite well for COM scripting. The problem: I want to take molfiles from multiple sources and normalize them so that they can be rendered with the same style settings by chemdoodle web components. The solution: I found that by converting a molfile into an InChI string, and then back into a molfile seems to retain the important structural information while at the same time normalizing the coordinates, and losing extraneous information, so this seems to be a reasonable way to go.
I first tried this manually in ChemDraw which fortunately my university has a site license for, because I surely can't afford it on my own and it worked well. I then looked for ways to automate it, and came upon OpenBabel. OpenBabel looks like an extremely useful open source! OpenBabel generates InChI strings that are identical to those generated by ChemDraw, but when I convert them back into molfiles, it struggles, and does not output a molecule that looks the same as the one originally input I was getting carbons with 5 bonds because it was protonating quaternary carbons for some reasonit also crashes when I ask for it to generate 2d coordinates the --gen2d option.
I didn't test it extensively to see if this was because I'm using particularly complicated molecules or maybe strange molfiles? Chemspider also has a nice API that might help with this sort of thing, but it apparently uses OpenBabel as the backend, and when I put in my InChI string the resulting molfile is unparsable by both ChemDraw and Chemdoodle.
In any case, OpenBabel didn't seem like it was going to work for me, there may be other open source software that would, but I've got a deadline, so I've got to use what I know will work, and right now that's ChemDraw.
There is also some more detailed documentation of the API, but it doesn't seem to correspond 1 to 1 with the interface I get when connecting with pywin32 Perkin Elmer markets a separate product ChemScriptwhich I'm sure makes all of this quite easy, and probably also has up to date documentation, but I haven't got a license for it, so I'll do what I can with ChemDraw. I've got Chemdraw Pro version In addition to looking at the online documentation, I also used COM makepy through PythonWin as suggested by the pywin32 documentation to generate the.
This all looks very complicated, but I'll try to stay focused and figure out how to do the simple, specific task I'm after. This actually wound up working pretty well, and did exactly what I was hoping for. Unfortunately, for a technical issue with the way ChemDraw generates InChI strings, I ended up taking a different approach eventually which I will detail in the next post.
Here's the code: Note: for this program to work, you must be windows and have ChemDraw installed Also, this program can't run in the background. When you run it, you should't be doing other things that will shift the window focus from chemdraw, or use the clipboard import os import win32com. Dispatch "WScript. EnsureDispatch 'ChemDraw. Application' connect to chemdraw chemdraw.
Open os. Activate sleep chemdraw must be the active application, so it can receive keyboard commands shell. OpenClipboard print clipboard. GetClipboardData win32con. CloseClipboard saving the string so we can do step 11 later sleep doc. SaveAs os. Chemdraw detects from the file name that we want to save it in MDL mol format doc.
