AZD-4573 is a selective and short-acting inhibitor of the serine threonine cyclin-dependent kinase 9, the catalytic subunit of the RNA polymeraseII elongation factor positive transcription elongation factor b. It also has a potential antineoplastic activ
β-Amanitin, a cyclic peptide toxin found in the poisonous Amanita phalloides mushroom, inhibits eukaryotic RNA polymeraseII and III, thereby disrupting protein synthesis.
Mal-C6-α-Amanitin is a drug-linker conjugate for ADC with potent antitumor activity by using α-Amanitin (an RNA polymeraseII inhibitor), linked via the ADC linker Mal-C6.
CDK12-IN-8(Compound Cpd143)是一种口服活性高且选择性强的细胞周期蛋白依赖性激酶 12(CDK12)抑制剂。通过抑制 CDK12 对 RNA 聚合酶 II C 端结构域(CTD)丝氨酸 2 的磷酸化,该化合物干扰基因转录的延伸以及 DNA 损伤修复途径。CDK12-IN-8 适用于研究CDK12高表达的癌症,例如小细胞肺癌和三阴性乳腺癌。
5-formylcytosine (5FC) is a rare base found in mammalian DNA. It participates in active DNA demethylation, changes DNA double helix structure, and reduces the transcription rate and substrate specificity of RNA polymeraseII.
TAF10 is one of many protein factors or coactivators associated with RNA polymeraseII activity. One vial of this peptide may be used as a methyltransferase acceptor peptide for more than 200 reactions at 15 μM.
cDPCP is a platinum-containing DNA-crosslinking agent.1Unlike cisplatin or oxaliplatin , cDPCP forms monofunctional DNA adducts. It is transported into cells by organic cation transporter 1 (OCT1) and OCT2, inhibiting proliferation of MDCK cells expressing the human transporters with IC50values of 8.1 and 1.5 μM, respectively. cDPCP inhibits RNA polymeraseII-mediated transcription in a reporter assay using HeLa cells. It increases survival in murine S180 sarcoma and P388 leukemia models when administered at doses of 40 and 80 mg/kg, respectively.2 1.Lovejoy, K.S., Todd, R.C., Zhang, S., et al.cis-Diammine(pyridine)chloroplatinum(II), a monofunctional platinum(II) antitumor agent: Uptake, structure, function, and prospectsProc.

γ-Amanitin an ADC cytotoxin and isolated from the mushroom. γ-Amanitin inhibits RNA polymeraseII and disrupts synthesis of mRNA. γ-Amanitin shows similar effects to α-Amanitin and β-Amanitin.
ε-Amanitin is a cyclic peptide obtained from various mushroom species. It exhibits a strong affinity for RNA polymeraseII and effectively inhibits its activity.
Thio-ITP, also known as 6-Thioinosine 5'-triphosphate, is a competitive inhibitor of RNA polymerase activity. It exhibits a strong apparent affinity towards the polymerases, with Ki values of 40.9 μM for RNA polymerase I and 38.0 μM for RNA polymeraseII.
