IC50 (binding) | = 20250 nM | BindingDB_Patents: In Vitro Enzyme Assays. IRE-1 alpha, T1 RNase, and RNase A assays carried out in vitro with several o-vanillin derivatives to demonstrate selectivity of the derivatives for IRE-1 alpha. T1 RNase was assayed as follows. Five ul of a reaction mixture comprising 1x reaction buffer (5x reaction buffer is 100 mM Hepes pH 7.5, 250 mM KOAc, 2.5 mM MgCl2), 3 mM DTT, and 0.4% polyethylene glycol water were added to each well of 384 well plates. Twenty-five nanoliters of a 1 mM test compound solution were added to test wells. Three ul of a 1/48,000 dilution of an approximately 200,000 U/ml RNase T1 (Worthington) preparation were added to each test well and to positive control wells (final concentration 49.5 pg/well). Negative control wells contained only reaction mixture and test compound. After spinning the plates at 1200 rpm for 30 seconds, 3 ul of the mini-XBP-1 mRNA stem-loop substrate described in Example 1 were added to each well of a control plate. | ChEMBL. | No reference |

Many chemical entities in TDR Targets come from high-throughput screenings with whole cells or tissue samples, and not all assayed compounds have been tested against a single a single target protein, probably because they get ruled out during screening process. Even if these compounds may have not been of interest in the original screening, they may come as interesting leads for other screening assays. Furthermore, we may be able to propose drug-target associations using chemical similarities and network patterns.
