FF2049
FF2049 is a selective HDAC1-3 PROTAC degrader (with a DC50 of 257 nM against HDAC1). FF2049 recruits the E3 ligase FEM1B to mediate ubiquitination and proteasomal degradation of HDAC1-3. FF2049 induces cell cycle arrest and Apoptosis in cells. FF2049 can be used in research related to multiple myeloma, acute monocytic leukemia, triple-negative breast cancer and glioblastoma.

FF2049 (90 min) potently inhibits recombinant HDAC1, HDAC2 and HDAC6 enzymes, with IC50 values of 0.074 μM, 0.156 μM and 0.009 μM, respectively; it shows weak inhibitory activity against HDAC4, with an IC50 of 13.3 μM[1].
FF2049 (2.5-25000 nM; 24 h) induces potent, concentration-dependent HDAC1 degradation in MM.1S cells via a FEM1B-, HDAC1- and neddylation-dependent mechanism, with a DC50 of 257 nM and a D_max of 85.2%, while leaving HDAC6 levels unaffected[1].
FF2049 (1 μM; 24 h) selectively degrades HDAC1, HDAC2 and HDAC3 in MM.1S cells without affecting other tested HDAC isoforms; it also exhibits strong cellular target-binding capacity, as evidenced by increased hyperacetylation levels of histone H3 and α-tubulin[1].
FF2049 (0.5 μM; 6 h) significantly induces the degradation of HDAC1 and HDAC2 in MM.1S cells, accompanied by the degradation of associated multi-subunit complex proteins (KDM1A, RCOR1, RCOR3, SIN3A, NCOR1, MIER1)[1].
FF2049 (10 μM; 24 h) induces significant HDAC1 degradation in MV4-11 (87%), MDA-MB-231 (53%) and U-87MG (75%) cells, confirming its activity against various cancer cell types[1].
FF2049 (71-72 h) exhibits antiproliferative activity against MM.1S (EC50 2.33 μM), MV4-11 (EC50 0.958 μM), MDA-MB-231 (EC50 26.5 μM) and U-87MG (EC50 37.4 μM) cells[1].
FF2049 (10 μM; 48 h) induces cell cycle arrest and apoptosis in MM.1S cells, which is evidenced by the decreased proportion of cells in S phase and increased proportion of cells in sub-G1 phase after treatment with 10 μM FF2049 for 48 h[1].
FF2049 (10 μM; 48 h) significantly induces early and late apoptosis in MM.1S cells after treatment at 10 μM for 48 h[1].
