nmrlearner's Avatar Drug repurposing for the identification of new Bcl-2 inhibitors: In vitro, STD-NMR, molecular docking, and dynamic simulation studies

BACKGROUND: The anti-apoptotic protein B-Cell Lymphoma 2 (Bcl-2) is a key target for the development of anti-cancer agents, as its overexpression can render cancer cells resistant to chemotherapeutic treatments.

[NMR paper] Analysis of enzyme reactions using NMR techniques: A case study with ?-methylacyl-CoA racemase (AMACR)
Oct 20, 2023 - 12:52 PM - by nmrlearner
nmrlearner's Avatar Analysis of enzyme reactions using NMR techniques: A case study with ?-methylacyl-CoA racemase (AMACR)

?-Methylacyl-CoA racemase (AMACR; P504S) catalyzes the conversion of R-2-methylacyl-CoA esters into their corresponding S-2-methylacyl-CoA epimers enabling their degradation by ?-oxidation. The enzyme also catalyzes the key epimerization reaction in the pharmacological activation pathway of ibuprofen and related drugs. AMACR protein levels and enzymatic activity are increased in prostate cancer, and the enzyme is a recognized drug target. Key to the development of novel treatments based on AMACR...

[NMR paper] Paramagnetic NMR to study iron sulfur proteins: 13C detected experiments illuminate the vicinity of the metal center

nmrlearner's Avatar Paramagnetic NMR to study iron sulfur proteins: 13C detected experiments illuminate the vicinity of the metal center

The robustness of NMR coherence transfer in proximity of a paramagnetic center depends on the relaxation properties of the nuclei involved. In the case of Iron-Sulfur Proteins, different pulse schemes or different parameter sets often provide complementary results. Tailored versions of HCACO and CACO experiments significantly increase the number of observed C^(?)/C' connectivities in highly paramagnetic systems, by recovering many resonances that were lost due to paramagnetic relaxation....

[NMR paper] Fragment-Based NMR Screening of the BPTF PHD Finger Methyl Lysine Reader Leads to the First Small-Molecule Inhibitors
Oct 19, 2023 - 1:17 PM - by nmrlearner
nmrlearner's Avatar Fragment-Based NMR Screening of the BPTF PHD Finger Methyl Lysine Reader Leads to the First Small-Molecule Inhibitors

Methyl lysine readers, specifically PHD fingers, are emerging epigenetic targets in human diseases. For example, several PHD finger fusions are implicated in clinical cases of acute myeloid leukemia, highlighting the potential for PHD inhibitors in disease regulation. However, limited chemical matter targeting PHD fingers exists. Here we report the first fragment-based screen against the BPTF PHD to identify several of the first reported BPTF PHD-targeting small-molecule ligands. We used...
