WebbK i is the inhibition constant for a drug; the concentration of competing ligand in a competition assay which would occupy 50% of the receptors if no ligand were present. [5] The Cheng-Prusoff equation produces good estimates at high agonist concentrations, but over- or under-estimates K i at low agonist concentrations. Webb21 maj 2024 · To investigate effects of ERK inhibitor U0126 on HSV-TK/GCV system, HSV-TK positive HXO-RB44 cells were pretreated with U0126 (10 µM) for 4 h at room temperature and subsequently treated with GCV at 20 µg/ml for 48 h, and then the cell viability was measured by MTT and compare with the control group that no treatment …

Webb16 nov. 2007 · Here we show that the FLT3, c-kit and PDGF directed tyrosine kinase inhibitor TK258 specifically targets slowly dividing human HPCs, but not rapidly proliferating HPCs or quiescent cells displaying an immature phenotype. For normal CD34+ cells, treatment of short-term cultures with TK258 resulted in a dose dependent … WebbEBV-PK but not EBV-TK mediates ACV and GCV susceptibilities, although susceptibility to the thymine nucleoside analogue ... virus production in wild-type EBV-infected 293T cells was inhibited by both GCV (50% inhibitory concentration [IC50] = 1.5 μM) and ACV (IC50 = 4.1 μM).

Pankreaskarzinom - PARP-Inhibition als zukünftige Therapieoption

WebbDescription. TK216 is a potent inhibitor of E26 transformation-specific (ETS) with anticancer activity. In vitro. In DLBCL cell lines, TK216 (500 nM; for 24-72 hours) induces apoptosis [1]. TK216 (0.03, 0.06, 0.125, 0.25, 0.5 μM) results in a dose-dependent inhibition of proliferation in Ewing Sarcoma A4573 cell line [1]. A tyrosine kinase inhibitor (TKI) is a pharmaceutical drug that inhibits tyrosine kinases. Tyrosine kinases are enzymes responsible for the activation of many proteins by signal transduction cascades. The proteins are activated by adding a phosphate group to the protein (phosphorylation), a step that TKIs inhibit. … Visa mer Numerous TKIs aiming at various tyrosine kinases have been generated by the originators of these compounds and proven to be effective anti-tumor agents and anti-leukemic agents. Based on this work Visa mer TKIs operate by four different mechanisms: they can compete with adenosine triphosphate (ATP), the phosphorylating … Visa mer • Bcr-Abl tyrosine-kinase inhibitor • Protein kinase inhibitor Visa mer Webb5 juli 2024 · Compounds 3 (0.899 nM), 11 (0.508 nM) and 17 (0.807) showed strong EGFR inhibitory activity compared to Erlotinib (0.439 nM) and these results are in agreement with the docking study. These results suggest that compounds could probably be promising anticancer agents with EGFR inhibitory activity. devanti benchtop dishwasher user manual
