1-(Methylsulfonyl)spiro[indoline-3,4'-piperidine]: A Potent c-Met/ALK Dual Inhibitor for Oncology Research
Product Overview
1-(Methylsulfonyl)spiro[indoline-3,4'-piperidine] (CAS: 178261-41-1) is a spirocyclic compound with a molecular formula of C₁₃H₁₉ClN₂O₂S and a molecular weight of 302.83. This high-purity (>95%) small molecule is recognized for its privileged scaffold in kinase inhibitor design, particularly targeting c-Met (hepatocyte growth factor receptor) and ALK (anaplastic lymphoma kinase), two critical oncogenic drivers in cancers .
Pharmacological Activity & Applications
1. Dual c-Met/ALK Inhibition
The compound’s spiro[indoline-3,4′-piperidine] core enables potent and selective inhibition of c-Met and ALK kinases. Preclinical studies demonstrate:
- Single-digit nM biochemical potency against c-Met and ALK .
- In vivo efficacy in suppressing tumor growth (>50% inhibition) in gastric carcinoma xenograft models .
- Oral bioavailability and favorable pharmacokinetics, making it suitable for therapeutic development .
2. Mechanism of Action (MoA)
The methylsulfonyl group enhances solubility and binding affinity, while the spiro structure allows solvent-exposed interactions with kinase domains, minimizing off-target effects . This selectivity is validated by 97-kinase panel screening, where the compound showed minimal cross-reactivity .
3. Therapeutic Potential
- Targets cancers with dysregulated c-Met/ALK signaling, including non-small cell lung cancer (NSCLC), gastric carcinoma, and glioblastoma .
- Acts as a chemically versatile intermediate for optimizing analogs with improved pharmacokinetic profiles .Synthesis & Quality Assurance
1. Efficient Synthetic Routes
- Four-component reactions involving isatin, methyl propiolate, and arylamines yield functionalized spiro[indoline-3,4'-piperidine] derivatives with high regioselectivity .
- Suzuki coupling and Mitsunobu reactions enable modular functionalization of the core structure for diverse analogs .
2. Quality Control
Supplied by reliable manufacturers (e.g., Bellingham & Stanley, Matrix Scientific), the product undergoes rigorous HPLC and NMR verification to ensure ≥95% purity .
