In vitro‑based Clint reported as ~13,515 L/h; both values refer to flow‑limited metabolism of chloroform.
Using the in vitro observed Km value together with the in vivo estimated Vmax, the resulting intrinsic clearance (Clint) for chloroform is approximately 20,695 L/h, which is close to the in‑vitro‑based Clint of about 13,515 L/h.

Estimated by subtracting the inhibition observed with SR-9186 alone from the combined inhibition with SR-9186 + thioTEPA.
By co-incubating tramadol with the inhibitors, the contribution of CYP2B6 to N-desmethyltramadol formation was estimated at 30 % after correcting for thioTEPA’s effect on CYP3A4.

Contribution to N-desmethyltramadol formation in HLM, may be overestimated due to lower CYP2D6 activity in this microsomal batch.
In addition to CYP2D6 and CYP3A4, a role for CYP2B6 of about 30% in the HLM metabolism of tramadol to N-desmethyltramadol (NDT) could be identified.

Hepatic Cleaned

This dataset contains 17,637 accepted finite scalar measurement children from the versioned canonical-base pipeline. A parent row with several unambiguous measurements can produce several child rows. Rejected, malformed, ambiguous, bounded, range-only, TDC-overlapping, and endpoint-unassignable records are not published here.

Cleaning

The following source columns are replaced in place with validated canonical or lexical normalizations:

  • smilescanonical_smiles
  • metric_typecanonical_endpoint_key
  • assay_systemassay_system_normalized
  • speciesspecies_normalized
  • molecular_formmolecular_form_normalized
  • reported_unitsunit_normalized
  • enzyme_or_pathwayenzyme_or_pathway_normalized
  • qualifying_conditionsqualifying_conditions_normalized
  • reported_valuescalar_value

The public column names on the left are retained; the names on the right identify the validated internal values used to replace them. Columns omitted from this dataset:

  • extraction_id: internal_identifier
  • global_identifier: internal_identifier
  • direction: all_null_in_dataset
  • auc_window: all_null_in_dataset

canonical_endpoint_key is the endpoint identity field. No condition_key is added. species_exact is populated only for explicit, unambiguous species references. Narrative and other source fields without a validated normalization remain source text.
