Uses: Scientific research. Group: Signaling pathways. CAS No. 2499663-01-1. Pack Sizes: 10 mM * 1 mL; 1 mg; 5 mg; 10 mg; 25 mg; 50 mg; 100 mg. Product ID: HY-134836.
STM2457 is a highly potent and selective first-in-class catalytic inhibitor of METTL3. Treatment of tumours with STM2457 leads to reduced AML growth and an increase in differentiation and apoptosis. These cellular effects are accompanied by selective reduction of m6A levels on known leukaemogenic mRNAs and a decrease in their expression consistent with a translational defect. Pharmacological inhibition of METTL3 in vivo leads to impaired engraftment and prolonged survival in various mouse models of AML, specifically targeting key stem cell subpopulations of AML. Uses: Designed for use in research and industrial production. Additional or Alternative Names: STM2457; STM-2457; STM 2457. Product Category: Inhibitors. Appearance: Solid powder. CAS No. 2499663-01-1. Molecular formula: C25H28N6O2. Mole weight: 444.54. Purity: >98%.

Streptokinase from Streptococcus sp., Recombinant
Streptokinase (SK) is an enzyme secreted by several species of streptococci that can bind and activate human plasminogen. SK is used as an effective and inexpensive thrombolysis medication in some cases of myocardial infarction (heart attack) and pulmonary embolism. Streptokinase belongs to a group of medications known as fibrinolytics, and complexes of streptokinase with human plasminogen can hydrolytically activate other unbound plasminogen by activating through bond cleavage to produce plasmin. There are three domains to Streptokinase, denoted α (residues 1-150), β (residues 151-287), and γ (residues 288-414). Each domain binds plasminogen, although none can activate plasminogen independently. Group: Enzymes. Synonyms: SK; EC 3.4.99.0; 9002-01-1. Purity: Greater than 97.0% as determined by:(a) Analysis by RP-HPLC.(b) Analysis by SDS-PAGE. SK.
