描述 | A1874 is a nutlin-based PROTAC targeting on BRD4, consist of a BRD4-ligand JQ1 linked to a MDM2 E3 ligase ligand RG7388. A1874 possesses dual function as it dose-dependently degraded its target BRD4, accompanied with the downregulation of c-MYC, as well as stabilization of P53 and upregulated P21 due to the efficient engagement of MDM2 by RG7388 in HCT116 cells exposure to A1874 at concentration ranging in 100nM-10μM post 24h. A1874 at concentration of 100nM achieved a near-maximum degradation of BRD4 by 98%. Incubation with A1874 ultimately resulted in a 97% loss in HCT116 cell viability, much more potent than JQ1 or RG7388 alone, for a synergistic antiproliferative effect by the combination of the E3 ligase ligand and targeting warhead. It seems that the potency to cell viability of A1874 may corelate to the status of P53 as A1874 was less potent against the cell line with mutant P53 or P53 depletion. A1875 is the inactive version of A1874[1]. |
