実験手順
TFA (1 ml, 12.98 mmol) was added to a flask of benzyl{4-[({3-[(tert-butoxycarbonyl)amino]-6-phenylpyridin-2-yl}amino)carbonyl]benzyl}carbamate (70 mg, 0.127 mmol) in dichloromethane (1 ml) at room temperature and the reaction was allowed to stir for 1 hour. The reaction was quenched by the addition of saturated sodium bicarbonate until bubbling stopped. The aqueous layer was extracted (2×) with EtOAc. The combined organic fractions were dried over sodium sulfate, filtered and concentrated. The residue was then purified by reverse phase HPLC to provide the desired product. 1H NMR (DMSO-d6) δ: (10.36s, 1H), 7.97 (d, J=8.2 Hz, 2H), 7.90 (d, J=7.3 Hz, 3H), 7.65 (d, J=8.4 Hz, 1H), 7.08-7.41 (m, 1H), 5.12 (s, 2H), 5.02 (s, 2H), 4.26 (d, J=6.3 Hz, 2H) MS: cal'd 453 (MH+), exp 453 (MH+). The in vitro HDAC1 IC50 of this compound is 32 nM. The IC50 of this compound in HCT-116 cells is 590 nM. Percent Cyp inhibitions at 10 μM are 7, 25 and 24%, for Cyp3A4, 2C9, and 2D6, respectively. The inflection point for MK-499 binding is 12.2 μM.
