It will take 3 years after changing job. Fortunately, I’m still working at early drug discovery field as chemoinformatician ;) As many drug hunter know that bioisosteric replacement is one of the major way for designing novel molecules from known biologically active molecules. Transformations from carboxylic acid to tetorazole, from amide to oxazole are majorContinue reading “Calculate similarity of popular bioisosters #RDKit #espsim #memo”
I hope all reader enjoying chemoinformatics ;)Unfortunately I’m struggling to make PPTX file in this year. So I can’t have enought time to coding. But It’s same for medicinal chemists. Because they often make presentation slide for project team, theier boss, senior etc…. They transfer SAR data from spread sheet to pptx. Sometime it seemsContinue reading “Make pptx file from Python #chemoinformatics #memo #python-pptx”
As many RDKitter know that rdSubstructLibrary is one of the cool tool for conductiong substructure search. Greg Landrum introduced how to use it in his great blog post. I love the method because it works very fast for substructure searching. So I would like to make CLI tool for making substructure library database. To doContinue reading “CLI tool for making ssslib #chemoinformatics #rdkit”
I introduced MMPDB v3 few days ago. The package is CLI tool. So user can do MMPA by typing command line. However the tool doesn’t provide API interface. I think, if we can use MMPDB on jupyter-notebook it’ll be more useful because output data can be used directly in coding process. MMPDB Cli interface isContinue reading “Use mmpdblib on jupyter notebook #rdkit #mmpdb #chemoinformatics”
Matched molecular pair (MMP) is not AI based compound design method however it’s still useful and powerful approach to do compound design. MMPDB is one of the cool package for MMP analysis. And Andrew who is developer of MMPDB preseted new version of MMPDB at RDKit UGM 2022. Version 3 is still developing state butContinue reading “Let’s use mmpdb v3 #memo #rdkit #chemoinformatics”
I often use flask for my web app development because the package is light weight web framework and easy to write. BTW rendering molecules as grid image is easy in jupyter notebook by using RDKit’s Draw.MolsToGridImage function. And also recently developed package named mols2grid is really cool for rendering molecules on jupyter notebook. mols2grid generaetesContinue reading “Embed mols2grid to web page #mols2grid #RDKit #webapp”
Last week I enjoyed RDKit UGM 2022. It was really great and exciting evenif I participated there from online. I hope I could participate RDKIT UGM 2023 locally ;) As you know RDKit is one of the useful OSS package for chemoinformatician. It has nice community and be developed actively. I respect the community andContinue reading “FW analysis make easily with rdkit contrib FW package #rdkit #chemoinformatics #memo”
I love RDKit because it supports lots of chemoinformatics features and it is supported top level scientific community. But for eary chemoinformacian, it’s required to learn python or C++ to write chemoinformatics code. As you know, Knime is good option for no-code chemoinformtatics. And another option for beginner is good wrapper of rdkit Recently theContinue reading “Make chemoinformatics coding more easily ! #RDKit #datamol”
I introduced to use user defined condaenv in Knime. It’s really useful I think. Make chemoinformatics workflow by Kinme with user defined conda envrionment #Knime #Chemoinforamtics #memo And as you know, REINVENT is the one of famous compound generation tool for drug discovery. Its community provides lots of example codes as jupyternotebook. After building someContinue reading “Generate molecules with REINVENT and make interactive plot #RDKit #Knime #REINVENT”
When I posted my memo about open science, @OlorenAI introduced python package named Oloren ChemEngine (OCE). I often use chemprop or interanly build system for QSAR tasks. ChemProp is the one of favorite package because it is easy to use and it includes web application flamework for users. I’ve never used OEC so I triedContinue reading “Useful python package for QSAR related tasks of chemoinformatician #chemoinformatics #oloren-ai #RDKit”
My blogsite was started 2013, so I took almost 10 years ;) It’s amazing. I’m enjoying writing the blog and sharing my code snippet. BTW, I’m working in pharmaceutical company as a chemoinformatician. So, is it risk to write chemoinformatics related post in my blog site….? I don’t think so. As many people know thatContinue reading “Let’s enjoy open science! #memo #diary”
Today is the last day of my summer vacation…. Due to COVID-19 pandemic, I and my family didn’t go travel during the vacation however, we’ll go to national championship of dodgeball game in next sturday. It will be exciting day! BTW as you know, rdkit has lots of contrib packages. And I would like toContinue reading “Calculate ligand RMSD with rdkit contrib package #RDKit #memo”
Visualize chemical space is important task for chemoinformatitian. And there are lots of way to represent chemical space. One of the common approach is PCA. And recently tSNE and UMAP are used. I wrote template code for plotting these data in my task but didn’t write code as a package. Today I found useful packageContinue reading “Useful package for ploting chemical space rapidly #chemoinformatics #memo”
I think workflow tool is useful for many chemoinformatician such as Knime, Pipeline Pilot(PP) and Orange. In my knowledge, it’s difficult to use user defined conda env in PP. Of course these workflow tools provides enough components to do many tasks. But I would like to have more flexibility to build chemoinformatics pipelines. Recently IContinue reading “Make chemoinformatics workflow by Kinme with user defined conda envrionment #Knime #Chemoinforamtics #memo”
Virtual Screening is important task of drug discovery projects. There are lots of approach for example Finger print based, substructure based and shape based screening. All approaches listed above is not only used in SBDD but also LBDD. And there are lots of apprications to do these tasks. I wrote scripts for these task andContinue reading “Useful package for virtual screening #chemoinformatics #RDKit”
To use rdkit from Rust, I introduced rdkit-sys before. And fortunately recent version of rdkit-sys cleat supports rdkit-env. It’s worth to use conda-env to build rdkit-sys because user don’t need to build rdkit from source code. Following code is almost same as my previous post but I would like to share it. At first, IContinue reading “Call RDKit from Rust with conda env ver2 #RDKit #RDKit-sys #Rust #Chemoinformatics”
General molecular generator with deep learning approach is difficult to fix substructure. But common SAR expansion by medchem is focus on specific part such as terminal part, core and linker. Linker is defined as a part which connect parts of molecules. Linker is important of drug design and is called scaffold when the linker connetsContinue reading “Generate molecules with Link-invent #RDKit #RINVENT #chemoinformatics”
I introduced rdkit-sys which is wrapper of rdkit for rust. The package development is ongoing so code is chaged frequentry. To use the package, user need to build rdkit with static link ON option. Build rdkit-sys with static link (.a) is efficient way for portability of the code however it means that it’s difficult toContinue reading “Call RDKit from Rust with conda env #RDKit #Rust #Chemoinformatics”
I wrote lots of chemoinformatics apps as web app. To do that I often use Flask / Django. It’s python packge so most of part can be written in python however it’s difficult to embed python directry in html document. Recently I found cool package for embedding python code in html, it’s name is pyscript.Continue reading “Run python script in html_file #memo #cording”
Most of chemoinformatitian will think that C6H6 means benzene and its SMILES strings will be ‘c1ccccc1’. However how do you think that how many possible combinations will be generated from molecular formula C6H6? ….. Yah, it’s interesting but difficult question. Recently I read interesting article published from Jounral of chemoinformaitcs. The title is ‘Surge: aContinue reading “Generate molecules from molecular formula #Chemoinformatics #memo #jcheminf”
