prmt5 in 2

PRMT5-IN-2 is an inhibitor of protein arginine methyltransferase 5.

PRMT5ligand 2 (Compound 38) is a ligand used for target proteins in PROTACs (Ligands for Target Protein for PROTACs). It is utilized in the synthesis of MS115.

Prmt5-IN-20 chloride is a potent protein arginine methyltransferase 5 (PRMT5) inhibitor. It strongly disrupts the activation of oncogenic transcriptional programs by blocking the symmetric dimethylation of histone and non-histone proteins, exhibiting outstanding anti-proliferative activity in various hematological and solid tumor models.

BLL5 Maleate (PRMT5-IN-20) is a selective PRMT5 inhibitor that blocks EBV-driven B-cell transformation and survival without affecting normal B cells.

PRMT5-IN-21 (compound 1) is a potent inhibitor of the cyclonucleoside enzyme PRMT5.

PRMT5-IN-22 (compound 53), an inhibitor of protein arginine methyltransferase 5 (PRMT5), exhibits anti-tumor activity. As a protein arginine methyltransferase, PRMT5 represents a novel anti-tumor target associated with epigenetic modification [1].

PRMT5-IN-23 (compound 50), an inhibitor of protein arginine methyltransferase 5 (PRMT5), exhibits anti-tumor activity. As a novel anti-tumor target associated with epigenetic modification, PRMT5 belongs to the protein arginine methyltransferase family [1].

PRMT5-IN-25 (compound 503) is a potent PRMT5 inhibitor with an inhibition constant (K i) of 0.06 nM and demonstrated antiproliferative properties [1].

PRMT5-IN-29 is a potent, orally active inhibitor of PRMT5, exhibiting an IC50 value of 1.5 μM, showing promise for use in advanced cancer research [1].

PRMT5-IN-28 (compound 36) serves as an inhibitor of the protein arginine methyltransferase 5 (PRMT5) enzyme, which is involved in gene transcription, mRNA splicing, DNA repair, protein localization, cell fate determination, and signal transduction. Dysregulated PRMT5 activity contributes to oncogenesis by promoting cancer cell proliferation, apoptosis resistance, invasion, metastasis, and impacting immune evasion [1].

PRMT5-MTA-IN-2 (compound 1) is a synergistic inhibitor of PRMT5 with an IC50 of less than 1.5 nM.

MRTX9768 hydrochloride is a potent, orally active PRMT5 inhibitor. MRTX9768 hydrochloride is a synthetic lethal-based inhibitor binding the PRMT5-MTA complex[1]. MRTX9768 inhibits SDMA and cell proliferation in HCT116 MTAP-del cells (SDMA IC50 3 nM; prolif. IC50 11 nM) with marked selectivity over HCT116 MTAP-WT cells (SDMA IC50 544 nM; prolif. IC50 861 nM)[1].MRTX9768 selectively targets MTAP/CDKN2A-deleted tumors[2][1]. In xenograft studies, oral administration of MRTX9768 demonstrates dose-dependent inhibition of SDMA in MTAP-del tumors, with less SDMA modulation observed in bone marrow[1]. [1]. Christopher R.

PRMT5-IN-31 (Compound 3m), a selective PRMT5 inhibitor (IC50: 0.31 μM), increases hnRNP E1 protein levels by occupying the substrate site of PRMT5 and establishing key interactions with amino acid residues. It exhibits antiproliferative properties against A549 cells through induction of apoptosis and inhibition of cell migration, while demonstrating high metabolic stability in human liver microsomes (T1/2: 132.4 min) [1].

Antiproliferative Agent-25 (Compound 3s4) is a selective PRMT5 inhibitor displaying an IC50 of 0.11 μM. It elevates hnRNP E1 protein levels and forms hydrogen bond interactions with SAM and the E444 residue of PRMT5. This compound exhibits antiproliferative effects in A549 cells by inducing apoptosis and inhibiting migration, albeit it presents high clearance rates, with half-lives of 21.8 minutes in human liver microsomes and 4.7 minutes in rat liver microsomes [1].
