PIP4K2C[1].
PIP4K2C (target protein) and the VHL E3 ubiquitin ligase complex. TMX-4153 simultaneously binds to PIP4K2C via its warhead and to VHL, leading to ubiquitination and proteasomal degradation of PIP4K2C. |
|---|---|
| ln Vitro |
In MOLT4, PIP4K2C is preferentially degraded by TMX-4153 (0.01, 0.05, 0.1, 0.5, 1 µM; 6 h)[1].
In MOLT4 cells, TMX-4153 at 0.01-1 uM for 6 hours induces selective degradation of PIP4K2C. The binding affinity (KD) to PIP4K2C is 42 nM, indicating high potency. It also inhibits the viability of PIP4K2C-dependent cell lines with low micromolar IC50. |
| ln Vivo |
In vivo activity data are not publicly available. Based on its mechanism, TMX-4153 is expected to reduce PIP4K2C protein levels in animal tissues after systemic administration, potentially affecting phosphoinositide signaling and cellular metabolism.
|
| Enzyme Assay |
A non-cell binding assay is performed using surface plasmon resonance (SPR) or fluorescence polarization. Purified recombinant PIP4K2C protein is immobilized, and TMX-4153 is flowed over at increasing concentrations (1-500 nM). The KD of 42 nM is determined by fitting binding kinetics.

Western Blot Analysis[1]
Cell Types: MOLT4 cells Tested Concentrations: 0.01, 0.05, 0.1, 0.5, 1 µM Incubation Duration: 6 h Experimental Results: Selectively degraded PIP4K2C with the maximal level of degradation (Dmax) value of 91% at 1 µM and half-maximal degradation concentration (DC50) value of 24 nM. MOLT4 cells (or other leukemia cell lines) are seeded in 96-well plates and treated with TMX-4153 at 0.01, 0.05, 0.1, 0.5, and 1 uM for 6 hours. Cells are lysed, and PIP4K2C protein levels are measured by Western blot with anti-PIP4K2C antibody. A dose-dependent degradation is observed. |
| Animal Protocol |
No detailed in vivo data are available. In a typical experiment, TMX-4153 would be administered to mice bearing PIP4K2C-dependent tumor xenografts by intraperitoneal injection (e.g., 10-50 mg/kg) daily for 2-3 weeks. Tumor growth inhibition and PIP4K2C knockdown in tumors would be assessed.
|
| ADME/Pharmacokinetics |
TMX-4153 is a lipophilic molecule with molecular weight 1079.74, which may limit oral bioavailability. It is typically formulated in DMSO for in vitro use; for in vivo, it would require a vehicle such as 10% DMSO + 90% PEG300 or a lipid-based formulation.
|
| Toxicity/Toxicokinetics |
No specific toxicity data are published. As a degrader of PIP4K2C, potential on-target toxicities may include disruption of phosphoinositide metabolism in normal tissues. Off-target degradation should be evaluated by proteomics. Standard chemical safety precautions apply.
