Embodiment 1
[0387] Example 1: (S)-4-(4-(4-(((2-(2,6-dioxopiperidin-3-yl)-1-oxoisoindoline-4-yl) Synthesis of oxy)methyl)benzyl)piperazin-1-yl)-3-fluorobenzonitrile (compound 2)
[0388]
[0389] (4S)-5-Amino-4-(benzyloxycarbonylamino)-5-oxo-pentanoic acid tert-butyl ester. To a solution of (2S)-2-(benzyloxycarbonylamino)-5-tert-butoxy-5-oxo-pentanoic acid (150g, 445mmol) in 1,4-dioxane (1.50L) Di-tert-butyl dicarbonate (155 g, 711 mmol), pyridine (70.3 g, 889 mmol) and ammonium bicarbonate (105 g, 1.33 mol) were added. The reaction mixture was stirred at 18°C for 16 hours, then concentrated. The residue was dissolved in ethyl acetate (5.0 L) and water (5.0 L), the organic layer was separated and washed with HCl (3.0 mL, 1 N), saturated sodium bicarbonate (3.0 L), brine (3.0 L), Drying over anhydrous sodium sulfate, filtration and concentration gave crude (4S)-5-amino-4-(benzyloxycarbonylamino)-5-oxo-pentanoic acid tert-butyl ester (450 g, crude material) as white Solid, which was...
Embodiment 2
[0399] Example 2: Anti-proliferative effect on multiple myeloma
[0400] Cell culture material: Human multiple myeloma cell lines were purchased from suppliers and cultured at 37 °C with 5% CO in the medium 2 ,As shown in Table 1. Lenalidomide- and pomalidomide-resistant cell lines were obtained as previously described (Lopez-Girona et al. Leukemia 2012;26(11):2335). All cell lines were maintained in log phase, and cell density and viability were monitored by trypan blue exclusion using a Vi-cell XR cell viability analyzer (Beckman Coulter, Brea, CA).

[0402]
[0403] Preparation of test article solutions: Assuming a maximum volume of 50 μL, compounds were plated into black 384-well plates (Corning Inc.) to a final DMSO volume of 0.1%. A 10-point dose-response starting at 10 μM with a dilution ratio of 1:3 was printed in duplicate by acoustic dispense using the EDC ATS-100 platform. Alternatively, use a 10-point dose...
Embodiment 3
[0408] Example 3: Off-target effects and impact of compound 1 / compound 2
[0409] α1 adrenergic and dopamine D2 receptors. METHODS: Binding and functional assays of α1 adrenergic and dopamine D2 receptors were performed by Eurofins Cerep according to their method.
[0410] α1 adrenergic receptors. Binding at 10 μM. Binding assays evaluate the affinity of the test articles for non-selective alpha 1 adrenergic receptors in the rat cerebral cortex. Membrane homogenates of the cerebral cortex were mixed with 0.25 nM [ 3 H] Prazosin was incubated with prazosin in duplicate at room temperature for 60 minutes. After the incubation period, samples were filtered through glass fiber filters, the filters were dried, and radioactivity was counted using a scintillation counter. Results are expressed as mean percent inhibition of control radioligand binding.
[0411] combined IC 50 . To determine the binding IC of nonselective α1-adrenergic receptors 50 , with different concentrati...
