Biological Activity
| ln Vitro | EPZ004777 hydrochloride, with an IC50 of 400±100 pM, has a strong concentration-suspension inhibitory action on DOT1L enzyme activity. On DOT1L, solutions of hydrochloride EPZ004777 suspend more HMTs (PRMT5, 521±137 nM; other, >50 μM). Prolonged HCl treatment with EPZ004777 has a substantial potential impact on MLL-rearranged cell lines. EPZ004777 hydrochloride markedly decreased the amount of viable MV4-11 and MOLM-13 cells, however it took some time for Jurkat cells to start growing. While Part One MV4-11 cells continued to divide when exposed to EPZ004777 hydrochloride, their population size did not alter over time, according to long-term growth curve tracking. At doses of 3 μM or above, EPZ004777 hydrochloride significantly inhibits MLL-AF9. Results MLL-AF10 and CALM-AF10 transformed cells' bone marrow stroma are inhibited by the EPZ004777 hydrochloride cycle [2]. | ||
| ln Vivo | The hydrochloride of EPZ004777 was well tolerated, and no appreciable toxicity was seen. Following 14 days of nonstop exposure to EPZ004777 hydrochloride, a complete blood count study revealed a substantial rise in total leukocytes as a result of an increase in neutrophils, monocytes, and lymphocytes. The hydrochloride dosage of EPZ004777 (50, 100, or 150 mg/mL) was well tolerated, and no appreciable weight loss was seen [1]. | ||
