Rdkit hydrogen bond acceptors
WebApr 30, 2016 · Re: [Rdkit-discuss] Gobbi hydrogen bond acceptor definition. Hi Konrad, You (and Peter later in the thread) make valid points about whether or not particular functional groups are donors or acceptors. There are certainly interesting discussions to be had about that - particularly when those discussions are backed up by an analysis of ... WebApr 30, 2016 · Re: [Rdkit-discuss] Gobbi hydrogen bond acceptor definition. Hi Greg, Thanks for your response. Peter is exactly right. There is wide spread agreement that the pi electrons of aromatic nitrogen atoms are not hydrogen bond acceptors. I do not have any experimental data off the top of my head to prove this. However from first principles, it is ...

WebJan 22, 2024 · H-bond donors and acceptors are being calculated according to the general rule, while the Lipinski violations are only counted based on oxygen and nitrogen. Acceptor atoms are defined to have a lone-pair electron. Donor atoms are connected with at least one H atom. CDD displays the default value for the major protonation form at physiological pH.
