[Rdkit-discuss] rdkit & Coordination chemistry on Mg

2022-03-22 Thread Marco Stenta
Dear RDKitters, I am struggling with working organometals and coordination complexes. with a small team, we are creating a series of recommendations to draw correctly organometals (catalyst, complexes, etc), so that we can use them in our chemoinformatics pipeline. I know it is a horrible mess out

[Rdkit-discuss] rdkit and pip

2021-05-26 Thread Marco Stenta
Dear Colleagues, I recently came across this https://pypi.org/project/rdkit-pypi/ is pip going to be supported officially by the dev community? any plan? getting out of the conda dependency might be beneficial to get slightly slimmer docker images. Thanks cheers, m __

Re: [Rdkit-discuss] proper technical term for generating virtual compounds with rdkit and smarts

2020-09-25 Thread Marco Stenta
Hi Folks, We are building a tool that generates libraries of compounds based on a list of reactants and a set of compatible reactants, and allows selection of the products. We define the process as "product-based reactant selection" from an old paper (at the end of the day we need to make these co

Dear RDKitters, I am devising some metrics to score chemical routes for my colleagues in process chemistry. One such metrics involves the usage of the atomic oxidation number https://www.periodni.com/oxidation_numbers_calculator.php I have a python script that does it, using an electro-negativity t

2019-08-29 Thread Marco Stenta
Dear Colleagues, I am looking for matched molecular pairs in a set of compounds using a custom definition of the bonds to be cut, because I am interested in a small set of transformations, that I define as SMARTS in the fragmentation step. It would be ideal to define the smirks, but I guess that is

Dear Colleagues, I am working on intramolecular hydrogen bonds, formed between donor-acceptors separated by 2,3,4 atoms, as described in the Roche paper: Kuhn, B.; Mohr, P.; Stahl, M. J. Med. Chem. 2010, 53, 2601. I will use SMARTS and RDKIT to identify and classify IMHB. I see from documentation
