AD4
Based on 1 publication(s) in Google Scholar
AD4 is a PROTAC that induces the degradation of PCLAF by recruiting cereblon. AD4 is also an artemisinin derivative. AD4 directly binds to PCLAF with a KD of 6.1 μM, and induces apoptosis and G1-phase cell cycle arrest. By degrading PCLAF, AD4 upregulates p21, reduces Rb phosphorylation, downregulates Bcl-2 and upregulates Bax, thereby activating the p21/Rb axis. AD4 can be used in studies related to acute B-lymphoblastic leukemia and PCLAF-dependent anticancer mechanisms .

In Vitro
AD4 (48 h) potently inhibits the proliferation of RS4;11 cells, RPMI8226 cells, and U266 cells, with IC50 values of 50.6 nM, 235.3 nM, and 342.8 nM, respectively[1].
AD4 (10-200 nM; 48 h) induces dose-dependent apoptosis in RS4;11 cells after 48 h of incubation, with the maximum effect observed at 200 nM[1].
AD4 (10-200 nM; 12-48 h) degrades PCLAF in RS4;11 cells in a dose-dependent manner, with a DC50 of 54.92 nM, while activating the p21/Rb pathway and regulating apoptosis-related proteins to exert antitumor activity [1].
AD4 (10-200 nM; 48 h) induces dose-dependent G1-phase cell cycle arrest in RS4;11 cells after 48 h of incubation, and exhibits superior activity to SM1044 (HY-160962) at matched concentrations [1].
AD4 directly binds to the purified PCLAF protein with a Kd value of 6.1 μM, and its affinity is higher than that of its parent compound SM1044[1].
PCLAF degradation induced by AD4 (0-48 h) in RS4;11 cells commences at 4 h and reaches its maximum level at 24 h[1].
AD4 (100 nM; washout)-induced degradation of PCLAF is reversible, and the PCLAF protein level fully recovers within 24 h after AD4 removal[1].
Co-treatment with AD4 (RS4;11; 12 h) and the parent compound SM1044 or the CRBN ligand pomalidomide restores PCLAF protein levels; the inactive PROTAC AD4a also fails to induce the same PCLAF degradation as AD4, which supports that the simultaneous binding of PCLAF and CRBN is an essential requirement for the degradation activity[1].
AD4 (100 μM; 45-75 °C for 10 min) increases the thermal stability of PCLAF in the CETSA assay[1].
AD4 (10-40 μM; room temperature for 0.5 h; Pronase E for 10 min) reduces the extent of proteolytic degradation of PCLAF in RS4;11 cell lysates[1].
AD4 exhibits a short metabolic half-life and rapid clearance in liver microsomes from humans and male Sprague-Dawley rats[1].
AD4 (100 nM; 12 h) significantly reduces the PCLAF protein level in RS4;11 cells; after combination with the proteasome inhibitor MG132 (HY-13259) (5 μM), the PCLAF protein level is restored, while other candidate proteins do not exhibit similarly prominent degradation[1].
AD4 (10-1000 nM) downregulates the anti-apoptotic protein Bcl-2 and upregulates the pro-apoptotic protein Bax in RS4;11 cells[1].
