CX-5461 is a selective, orally active RNA polymerase I inhibitor. CX-5461 disrupts the formation of the SL1-rDNA complex, thereby blocking the transcription initiation of ribosomal RNA without altering the activity of RNA polymerase II, DNA replication, or protein translation processes. CX-5461 upregulates the expression of p21, MDM2, Sestrin1/2, and phosphorylated AMPKα, and reduces the level of phosphorylated Akt. CX-5461 induces G2/G2/M cell cycle arrest, Autophagy, Apoptosis, and cellular senescence, and activates CHK1, CHK2, and RPA. CX-5461 can be used in research related to osteosarcoma, cervical cancer, hematologic malignancies, high-grade serous ovarian cancer, and solid tumors .

Purity:  99.89%
Synonyms: (+)-BAY-1251152; (+)-VIP152; (S)-Enitociclib
Enitociclib ((+)-BAY-1251152; (+)-VIP152) is a selective CDK9 inhibitor (IC50=3 nM) that inhibits transcriptional elongation by blocking Ser2/Ser5 phosphorylation of RNA polymerase II. Enitociclib specifically depletes key short-lived proteins such as c-MYC, MCL-1 and induces tumor cell apoptosis. Enitociclib also interferes with the production of enhancer RNAs (eRNA) and enhancer-promoter interactions, and downregulates oncogene expression at the epigenetic level. Enitociclib exerts synergistic effects with agents including Bortezomib (HY-10227), Lenalidomide (HY-A0003), Pomalidomide (HY-10984), Venetoclax (HY-15531) and Paclitaxel (HY-B0015), and even reverses paclitaxel resistance. Enitociclib serves as a vital research tool for various malignancies such as double-hit diffuse large B-cell lymphoma, multiple myeloma and pancreatic ductal adenocarcinoma .

Oncrasin-1 is an RNA polymerase inhibitor. Oncrasin-1 suppresses the phosphorylation of the largest subunit of RNA polymerase II and the expression of intronless reporter genes in sensitive cells. Oncrasin-1 effectively kills various human lung cancer cells with K-Ras mutations. Oncrasin-1 leads to coaggregation of PKCι and splicing factors into megaspliceosomes. Oncrasin-1 induces malfunction in the RNA processing machinery. Oncrasin-1 is an anti-cancer agent and can therefore be studied in research for lung cancer .
