Description

ASP3026 is an ATP-competitive, second-generation ALK inhibitor (IC₅₀ = 3.5 nM) that also inhibits ROS (IC₅₀ = 8.9 nM) and ACK (IC₅₀ = 5.8 nM). It inhibits neuroblastoma-activating ALK mutants F1174L (IC₅₀ = 10 nM) and R1275Q (IC₅₀ = 5.4 nM) and demonstrates antitumor activity in xenograft mouse models. ASP3026 has been shown to overcome crizotinib resistance in non-small cell lung cancer, and is currently being evaluated in clinical trials of patients with ALK-positive solid tumors.

Uses

ASP3026 is a novel and selective anaplastic lymphoma kinase (ALK) inhibitor that shows potent anti-tumor activities. ASP3026 also shows potential efficacy for non-small cell lung cancer (NSCLC) and is expected to improve the therapeutic outcomes of patients with cancer with ALK abnormality. Potent ALK inhibitor.

Definition

ChEBI: ASP-3026 is a member of the class of diamino-1,3,5-triazines that is 1,3,5-triazine-2,4-diamine in which the amino groups at positions 2 and 4 are respectively carrying 2-methoxy-4-[4-(4-methylpiperazin-1-yl)piperidin-1-yl]phenyl and 2-(propan-2-ylsulfonyl)phenyl substituents. It is a potent inhibitor of anaplastic lymphoma kinase (ALK), Ack and ROS1 activity (IC50 values are 3.5, 5.8 and 8.9 nM respectively) and exhibits anti-cancer properties. It has a role as an antineoplastic agent, an apoptosis inducer, an EC 2.7.10.1 (receptor protein-tyrosine kinase) inhibitor, an antimalarial and an EC 6.1.1.6 (lysine--tRNA ligase) inhibitor. It is a secondary amino compound, a monomethoxybenzene, a N-methylpiperazine, an aromatic amine, a diamino-1,3,5-triazine, a member of piperidines and a sulfone.

Synthesis

Alternative to Step 7, Method 2 (Example of using a reducing catalyst): Synthesis of N-{2-methoxy-4-[4-(4-(4-methylpiperazin-1-yl)piperidin-1-yl]phenyl}-N'-[2-(propane-2-sulfonyl)phenyl]-1 ,3,5-triazine-2,4-diamine (compounds of formula (1)). 1-[3-Methoxy-4-({4-[2-(propane-2-sulfonyl)anilino]-1,3,5-triazin-2-yl}amino)phenyl]piperidin-4-one (5.0 g), tetrahydrofuran (30 mL), N-methylpiperazine (1.81 g), and 10% palladium-carbon (~50% wet product, 0.8 g) were mixed. The mixture was stirred at 40°C for 7 hours under a hydrogen atmosphere (2.4821 x 10^5 Pa). Upon completion of the reaction, the palladium carbon was removed by filtration and washed with tetrahydrofuran (10 mL). The combined filtrates were concentrated under reduced pressure. To the concentrated residue was added 2-butanone (9 mL) and the resulting mixture was stirred at 60°C for 30 minutes and then slowly cooled to 30°C. After addition of n-heptane (9 mL), the mixture was stirred at room temperature for 19 h. The precipitated crystals were collected by filtration. The crystals were washed with a mixture of 2-butanone (1 mL) and n-heptane (1 mL) and then dried under reduced pressure at 40 °C to afford the target product N-{2-methoxy-4-[4-(4-methylpiperazin-1-yl)piperidin-1-yl]phenyl}-N'-[2-(propane-2-sulfonyl)phenyl]-1,3,5-triazine-2,4-diamine (3.09 g, yield 88.0%).
