MTP-B1

MTP-B1 is a POLRMT MtPTAC degrader that activates mitochondrial ClpP. MTP-B1 recruits ClpP as a protease module to POLRMT, inducing ClpP-dependent proteolysis and reducing POLRMT protein levels. MTP-B1 induces ROS and apoptosis. MTP-B1 inhibits proliferation, clonogenic growth, oxidative phosphorylation pathway gene expression, and mitochondrial transcription. MTP-B1 inhibits tumor growth in xenograft tumor mouse models and reduces tumor Ki67. MTP-B1 can be used for pancreatic cancer research (pink: POLRMT inhibitor: HY-181072; blue: small molecule that activates mitochondrial protease ClpP: HY-189815.

Anti-cancer

MTP-B1 (0.5-5 μM and 125-5000 nM; 24 h) potently degrades POLRMT in MIA PaCa-2 cells with a DC₅₀ of 187.2 nM and a D_max of 98.18%; in AsPC-1 cells, the DC₅₀ is 416.9 nM^[1].
MTP-B1 (1 μM; 0-48 h) rapidly degrades POLRMT in MIA PaCa-2 cells, and the degradation persists after compound washout^[1].
MTP-B1 (0.1-1 μM) reduces POLRMT immunofluorescence in MIA PaCa-2 cells in a dose-dependent manner^[1].

Anti-cancer

Protein/Amino Acid Metabolism

MTP-B1 (7 days) exhibits potent antiproliferative activity against MIA PaCa-2 and AsPC-1 cells with IC₅₀ values of 5.08 and 57.76 nM, respectively, and degrades POLRMT with a DC₅₀ of 8.81 nM^[1].

Mitochondrial Oxidative Phosphorylation

MTP-B1 broadly inhibits OXPHOS gene expression and mitochondrial transcription^[1].

Oxidative Stress

Mitochondrial Function

Anti-cancer

Apoptosis

MTP-B1 (1-500 nM) inhibits clonogenic growth of MIA PaCa-2 cells and induces ROS and apoptosis without affecting cell cycle progression or mitochondrial membrane potential^[1].

Others

MTP-B1 (1 μM)-induced POLRMT degradation requires simultaneous binding to both POLRMT and ClpP, and is independent of CRL-dependent ubiquitination and the autophagy-lysosomal pathway^[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Western Blot Analysis^[1]

Concentration:

1 μM (time-course); 1 μM for 24 h followed by washout
Incubation Time:

Result:

MTP-B1 induced more than 50% POLRMT degradation within 16 h and near-complete degradation by 24 h.
A lower-molecular-weight POLRMT species appeared with degradation.
After washout, no appreciable POLRMT recovery was detected within 24 h, with only partial restoration at 48 h.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
