0-211 |
Sentence |
denotes |
Dias et al. [379] took a similar approach as Fry et al. [377] in that they took known inhibitors of a protein-protein interaction, and dissected them into individual fragments to assess a protein’s drug-ability. |
| T581 |
212-352 |
Sentence |
denotes |
The interaction studied was that between the proteins von Hippel–Lindau (VHL), and the alpha subunit of hypoxia-inducible factor 1 (HIF-1α). |
| T582 |
353-542 |
Sentence |
denotes |
Twelve compounds (known inhibitors and derived fragments) were developed using a crystal structure of HIF-1α peptide bound to the stable multiprotein complex pVHL-elongin C:elongin B (VCB). |
| T583 |
543-784 |
Sentence |
denotes |
Each of these compounds was screened using three separate NMR techniques, Saturation Transfer Difference (STD), Carr–Purcell–Meiboom–Gill (CPMG) relaxation experiments, and WaterLOGSY (to assess drug binding and to predict drug binding mode. |
| T584 |
785-1028 |
Sentence |
denotes |
Each compound that was unambiguously detected (i.e., the molecule was identified as successfully binding by at least two of the three NMR methods of STD, CPMG, and WaterLOGSY) was subjected to further analysis by ITC and X-ray crystallography. |
| T585 |
1029-1196 |
Sentence |
denotes |
ITC was used to determine the dissociation constants of binding molecules, and X-ray crystallography was used to confirm the binding mode predicted by the NMR studies. |
| T586 |
1197-1446 |
Sentence |
denotes |
Generally speaking, the designed fragments had similar ligands efficacies compared to the parent molecules but had much higher dissociation constants (Kd values), meaning that the fragments bound less tightly than the original parent molecule [379]. |
| T587 |
1447-1812 |
Sentence |
denotes |
With this example, it is possible to see the strength of using NMR as its own hit-validation tool (i.e., three different NMR techniques were used for screening compounds [379]), and yet, the follow-up of NMR studies with ITC and X-ray crystallography was useful in providing a basis for assessing the drug-ability of a protein-protein interaction [385,386,387,388]. |
| T588 |
1813-1975 |
Sentence |
denotes |
Thus, it is clear to see that NMR is a prominent method of hit-validation in drug discovery research, especially in combination with other biophysical techniques. |
