If the interactions between the protein and support are not carefully designed, there is a tendency to produce reactors possessing randomly oriented proteins with some orientations providing inactive forms.
Rather, active and inactive compounds might also be compared, provided confirmed inactive compounds are available for a given target.
Further modification on ring C of derivatives 1, 4 and 14 by transforming the hydroxyl group at C-12 into the ketone group provided three inactive products 26 28 with IC50 values higher than 485.1 μM, demonstrating that hydroxyl group at C-12 is crucial for antiviral activity.
If a contact email address was not found, if no response was received, or if the email address provided was inactive, we did a further Google Scholar and Google search using the trial registration number, investigator name, or both (BS, checked by AB).
However, in order to provide an independent validation, an external validation test set was provided with inactives selected from PubChem database [23].
This provides an inactive SOFA-HDV ribozyme, i.e. off conformation.
Also, the reduced, ionized cysteine thiol, or a partially oxidized form is susceptible to conjugation with glutathione, which provides an inactive, but potentially reactivatable form of the enzyme (22).
We used the binary bioactivity outcome annotations, e.g. active versus inactive, provided in the dataset submissions as the corresponding activities.
In addition, the PubChem bioactivity outcome annotations (i.e., active or inactive) provided by depositors were directly used to obtain the bioactivity potency differences.
First, we have shown that the stably-integrated Ptetbi becomes silenced, provided it is inactive during development, and that high tTA/rtTA levels in neurons allow for Ptetbi un-silencing over time.
