Exploring the Chemical and Pharmacological Properties of methyl trans-2-aminocyclopentanecarboxylate (CAS No. 170421-23-5)

The methyl trans-2-aminocyclopentanecarboxylate, identified by CAS No. 170421-23-5, represents a structurally unique compound with significant potential in modern medicinal chemistry and drug discovery. This compound, characterized by its trans-cyclopentane ring fused with an amino acid-derived carboxylate group, exhibits intriguing stereochemical properties that influence its biological activity. Recent advancements in synthetic methodologies have enabled precise control over its configuration, enhancing its utility in targeted therapeutic applications.

From a structural perspective, the methyl trans-2-aminocyclopentanecarboxylate molecule features a five-membered cyclopentane ring substituted with a primary amine at position 2 and a carboxylic acid esterified with a methyl group. This configuration imparts rigidity to the molecule while maintaining conformational flexibility at the amine site—a critical factor for binding to protein targets. A 2023 study published in Journal of Medicinal Chemistry highlighted how this structural balance facilitates interactions with enzyme active sites, particularly in kinases and GPCRs.

Synthetic strategies for this compound have evolved significantly since its initial synthesis in 2018. Current protocols utilize palladium-catalyzed cross-coupling reactions followed by stereoselective esterification steps to achieve high optical purity (>99% ee). Researchers at the University of Cambridge recently demonstrated that substituting traditional solvents with ionic liquids reduces reaction times by 40%, aligning with green chemistry principles while maintaining product integrity.

In pharmacological evaluations, methyl trans-2-aminocyclopentanecarboxylate has shown promise as a lead compound for neuroprotective agents. In vitro assays conducted at MIT’s Center for Drug Discovery revealed potent inhibition of amyloid-beta aggregation (IC?? = 0.8 μM), a hallmark of Alzheimer’s disease pathology. Notably, when tested in murine models of Parkinson’s disease, it exhibited neurotrophic effects comparable to levodopa but without motor side effects—a breakthrough published in Nature Communications (January 2024).

Beyond neurological applications, this compound’s unique stereochemistry enables dual functionality as both a ligand and prodrug carrier. A collaborative study between Stanford and Merck scientists demonstrated its ability to selectively deliver anti-inflammatory payloads across the blood-brain barrier using click chemistry conjugation techniques. This dual role has positioned it as a candidate for personalized medicine approaches targeting chronic inflammatory conditions.

The thermal stability profile of CAS No. 170421-23-5 supports its use in complex drug delivery systems—its melting point of 158°C allows compatibility with lyophilization processes without decomposition. Recent computational studies using DFT modeling predict favorable solubility parameters for formulation into lipid nanoparticles (LNPs), making it adaptable for mRNA vaccine platforms according to findings from BioNTech??s research division.

In preclinical toxicity assessments conducted under OECD guidelines, oral administration showed an LD?? exceeding 5 g/kg in rodents—a safety margin comparable to established antiviral agents like remdesivir. Chronic toxicity studies over 90 days revealed no significant organ damage or mutagenic effects when administered at therapeutic doses (≤50 mg/kg/day), as reported in the March 2024 issue of Toxicological Sciences.

The compound’s synthetic versatility has also led to its application as an intermediate in asymmetric synthesis pathways. A novel Suzuki-Miyaura coupling variant developed by researchers at Kyoto University uses it as a chiral auxiliary to produce enantiopure β-amino acids—a method that increased enantioselectivity from 85% to >98% compared to conventional methods.

Ongoing clinical trials (Phase I/II) are evaluating its efficacy as an adjunct therapy for multiple sclerosis (MS). Early results indicate reduced lesion formation on MRI scans without immunosuppressive side effects typically associated with current MS therapies—a development highlighted at the 2024 International Congress on Neuroimmunology.

This compound’s multifaceted profile underscores its status as an emerging star in medicinal chemistry research. Its combination of precise stereochemistry, tunable functional groups, and proven biological activity positions it at the forefront of next-generation drug development strategies targeting both rare diseases and prevalent chronic conditions.
