Starting Point

GSK2290170A (TCMDC-143693) identified by GSK in a high throughput screen (to be published shortly).

TCMDC-143693, the Starting Point for OSTB Series 2

Properties

Inherited data from GSK for TCMDC-143693: MIC vs. H37Rv = 10 μM, active against non-replicating TB (>50% inhibition) in 10 experiments out of 13) and with mean PXC50 of 5.2 μM. Toxicity vs. HepG2 was >100 μM. cLogP is 3.1 and (presumably) measured solubility is 72 μg/mL. Chrom LogD (pH 7.4) is 5.21, and molecular weight 385.

Known occurrences

"GSK2290170A" and "TCMDC-143693" were, when this page was created, absent from Google. Pubchem search leads to a patent.

ChEMBL flags up that a search on SureChEMBL reveals that the compound has appeared (along with nearest neighbours) on 2 patents of the same patent family: https://www.surechembl.org/document/US-20090176778-A1/ and https://www.surechembl.org/document/US-20120121540-A1/

Predicted Target

A prediction of the target was carried out by Marc Marti-Renom and ChEMBL as part of the original HTS paper identifying the compound.

The compound (TCMDC-143693) has four predictions, three from Marc's approach and one from the ChEMBL’s approach. (The details on how the predictions were identified are in the forthcoming manuscript).

Marc's predictions:
1) O06266 (an epoxide hydrolase). Link: TCMDC-143693 —> 3TH-S38-3ans_A —> S38-O06266 (i.e. the GSK compound is similar to 3TH in PDB, which was co-crystallized with 3ans (a Human soluble epoxide hydrolase in complex with a synthetic inhibitor). In turn, the model of the Tuberculosis epoxide hydrolase (O06266) was based on 3ans template and the binding site was conserved. Thus, the path links TCMDC-143693 to O06266.
2) A2VJ47 (an epoxide hydrolase ephB), TCMDC-143693 —> 3TH-S38-3ans_A —> S38-A2VJ47
3) P64411 (Heat shock protein 90, TCMDC-143693 —> 3TH-PFT-3k99_A —> PFT-P64411

The EBI prediction:
P96222 (Mtb HTH-type transcriptional regulator Eth) now http://www.uniprot.org/uniprot/P9WMC1 and https://www.ebi.ac.uk/chembl/target/inspect/CHEMBL1772929. The compound shares a lot of structural features found in known actives (activity <=10 μM) for this target in ChEMBL. These features include the thiophene ring, -CF3, pyrrole ring and nitrile.

Synthetic Chemistry

The starting compound was resynthesized according to (Jessica insert and link to lit source). (Jessica describe synthesis and insert scheme here).
