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”
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”
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”
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”
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”
I enjoyed 18th mishima.syk meeting at last weekend. I think the community is really cool and worth to join for caching the cutting edge of chemo/bio informatics ;) Feel free to participate and present here if you have interest the meeting. In the meeting, yamasakit_ introduced “Rust basics” with live coding! Fortunately his presantation materialContinue reading “Use RDKit from Rust v2 #RDKit #Rust”
Kinase is one of the attractive target for drug discovery. So there are lots of data not only protein but also inhibitor available. ChEMBL is useful public data source for Kinase inhibitor data however to use the data, we need to retrieve data from the DB and curate it. Of course there are commercial databaseContinue reading “Make curated Kinase inhibitor dataset from ChEMBL30 #memo #chemoinformatcs”
Recently, ChEMBL ver. 30 is released. I’ve installed it in my PC and added rdkit schema ;) And current chembl ftp site provides monomer library of HELM. @magattaca posted really useful blog post in Japanese https://magattaca.hatenablog.com/entry/2020/11/25/004829. The post describes about HELM, its monomer and render these monomers. I’m interested in how to build peptide fromContinue reading “Build peptide from monomer library from ChEMBL #RDKit #ChEMBL #Chemoinformatics”
Recently I posted really useful package named molplotly. The package can make interactive plot with compound structure as hover. Inspired the activity, I tried to wrote code for making chemical space mapping with interactive rendering of molecules. Base code came from my previous post. There small changes in dash part because of I used newContinue reading “Make interactive chemical space plot with Dash #RDKit #useful_rdkit_utils #Dash #Chemoinfomratics”
Some days ago, @WillMcCorki1 introduced really cool package named molplotly. Thanks for sharing the information. Molplotly is add-on to ploty for rendering molecular image on mouseover like TIBCO Spotfire. The package(https://github.com/wjm41/molplotly) uses JupyterDash for integrating JupyterNotebook so it’s easy to embed interactive chemoinformatics chart in JupyterNotebook. However, it’s difficult to use the package from outsideContinue reading “Integration of molplotly and Flask for developing chemoinformatics web app #RDKit #molplotly #Flask”
Matched molecular pairs are popular approach to transform molecules with prior knowledge of medicinal chemistry. MMPDB is useful open source package for managing MMP dataset which is derived from GSK under the 3-clause BSD license. It is easy to use and work really fast. I love it the package. However current version of MMPDB supportsContinue reading “Let’s update MMPDB #RDKit #mmpdb #Chemoinformatcs”
Recently Rust is becoming popular language and I have interest Rust. There is a hurdle for me to move programming language from python to others because I would like to use RDKit from my coding environment for chemoinformatics tasks ;) As many chemoinformaticians know that recently rdkit provides new C Foreign Function Interface (CFFI). AndContinue reading “Use RDKit from Rust #RDKit #rdkitcffi #Rust”
