N-Methyl-4-(4-Methylpiperazin-1-Yl)Aniline: A Comprehensive Overview of Its Chemistry and Applications

The compound N-methyl-4-(4-methylpiperazin-1-Yl)aniline, identified by the CAS registry number 1224684-96-1, represents a structurally complex aromatic amine with significant potential in contemporary chemo-biomedical research. This molecule features a substituted phenyl ring bearing both an N-methyl group and a 4-methylpiperazine moiety attached at the para position, creating a scaffold with unique electronic properties and hydrogen bonding capabilities. Recent advancements in computational chemistry have highlighted its capacity to interact with biological targets through π-stacking and electrostatic interactions, positioning it as a promising lead compound for drug discovery initiatives.

In terms of synthetic chemistry, this compound has been successfully prepared via optimized multistep protocols that emphasize atom economy principles. A notable study published in Journal of Medicinal Chemistry (2023) demonstrated a novel Suzuki-Miyaura coupling approach to construct the piperazine-aniline hybrid framework under mild conditions. Researchers achieved 89% yield using palladium catalysts stabilized by phosphine ligands, which significantly reduces reaction time compared to traditional methods. The introduction of methyl groups at both the nitrogen atom and the piperazine ring enhances solubility while modulating basicity—a critical factor for improving pharmacokinetic profiles in drug candidates.

Biochemical studies reveal intriguing interactions between this compound and protein kinases involved in oncogenic signaling pathways. A collaborative research team from MIT and Stanford recently reported that N-methyl substitution increases binding affinity to epidermal growth factor receptor (EGFR) by 3-fold compared to its parent aniline derivative. The 4-methylpiperazine group forms a stable hydrogen bond network with the ATP-binding pocket, effectively inhibiting tyrosine kinase activity without affecting non-target enzymes. These findings were validated through X-ray crystallography studies showing precise molecular docking at residue positions 755–760 of EGFR's catalytic domain.

In drug development pipelines, this compound serves as a versatile building block for creating multi-targeted therapeutics. Pharmaceutical researchers have employed it as an intermediate in synthesizing second-generation kinase inhibitors with improved selectivity profiles. A groundbreaking 2023 publication in Nature Communications describes its use in developing PROTAC-based molecules that induce EGFR degradation through selective ubiquitination—a mechanism offering advantages over conventional inhibitors by addressing drug resistance issues.

Cytotoxicity evaluations conducted under ISO 10993 standards demonstrate low hemolytic activity (<0.5% at 50 μM) while maintaining high efficacy against cancer cell lines such as A549 (IC?? = 0.8 μM). This favorable therapeutic index is attributed to the steric hindrance introduced by the methyl groups, which prevents off-target interactions observed in earlier generations of kinase inhibitors. Cell permeability assays using parallel artificial membrane (PAMPA) models showed logP values between 3.2–3.6, indicating optimal balance between hydrophilicity and lipophilicity for systemic administration.

In vivo pharmacokinetic studies using murine models revealed linear dose-response relationships with half-life values ranging from 5–7 hours after intravenous administration. The presence of both aromatic and aliphatic nitrogen-containing groups facilitates metabolic stability while avoiding cytochrome P450 enzyme induction—a critical consideration for chronic treatment regimens. These properties align with FDA guidelines for drug candidates targeting solid tumors where sustained plasma concentrations are required.

The structural flexibility afforded by the piperazine ring allows for post-synthesis functionalization strategies outlined in recent American Chemical Society Symposium Series articles (2023). Researchers have demonstrated site-specific attachment of polyethylene glycol chains via click chemistry, enhancing aqueous solubility without compromising receptor binding affinity. Such modifications are pivotal in developing prodrugs that overcome bioavailability challenges associated with traditional small molecule therapies.

Spectroscopic analysis confirms characteristic UV-vis absorption peaks at 285 nm (ε = 8,500 L·mol?1·cm?1), enabling real-time monitoring during preclinical trials through fluorescence polarization assays. Nuclear magnetic resonance (1H NMR) data shows distinct signals at δ 3.3–3.5 ppm corresponding to the methylated piperazine protons, providing unambiguous structural confirmation during quality control processes—a requirement emphasized in ICH Q6A guidelines for active pharmaceutical ingredients.

Thermal stability studies conducted via differential scanning calorimetry (DSC) indicate decomposition temperatures above 310°C under nitrogen atmosphere, ensuring compatibility with high-throughput screening platforms that require lyophilized storage conditions (-80°C). This stability is further corroborated by XRPD analysis showing no crystalline phase changes after accelerated aging tests at 40°C/75% RH for three months—a key parameter for maintaining consistent bioactivity during clinical trial preparations.

The compound's unique electronic configuration has sparked interest in photodynamic therapy applications as reported in Bioorganic & Medicinal Chemistry Letters. When conjugated with porphyrin derivatives, it exhibits singlet oxygen generation efficiency up to 78% under near-infrared irradiation—a breakthrough for deep tissue penetration applications compared to conventional photosensitizers limited by visible light requirements.

Ongoing investigations focus on its role as a chiral ligand precursor in asymmetric synthesis processes documented in recent Angewandte Chemie International Edition publications (January 2024). The introduction of optically pure variants through enzymatic resolution methods has enabled stereoselective synthesis of β-lactam antibiotics with enhanced antibacterial efficacy—demonstrating its utility beyond traditional medicinal chemistry into advanced antibiotic development strategies.

Critical reviews published this year highlight its potential as a template for designing dual-action agents combining kinase inhibition with autophagy modulation mechanisms described in Cancer Research. By incorporating bioisosteric replacements into the piperazine backbone while retaining essential pharmacophore elements, researchers are exploring synergistic effects against multidrug-resistant cancer phenotypes—addressing one of the most pressing challenges in current oncology research.

Safety assessment data adheres strictly to OECD guidelines without triggering any regulatory classifications under current GHS standards due to its non-hazardous profile when handled according to standard laboratory protocols. Toxicity studies on zebrafish embryos showed no developmental abnormalities at concentrations up to 1 mM—far exceeding therapeutic dosing levels—while mutagenicity assays using Ames test protocols demonstrated negative results across all bacterial strains tested.

This molecule's structural versatility has also found application in developing fluorescent probes reported recently (Analytical Chemistry, March 2024). By attaching fluorophores via amidation reactions at strategic positions on its backbone, researchers created pH-sensitive sensors capable of detecting intracellular alkalization events associated with tumor microenvironments—a novel diagnostic approach validated through confocal microscopy imaging studies on metastatic breast cancer cells.

In summary,N-methyl-4-(4-methylpiperazin-1-Yl)aniline (CAS No: 1224684-96-1)) embodies contemporary advancements in structure-based drug design principles while maintaining practical advantages such as synthetic accessibility and metabolic stability crucial for translational research success. Its documented interactions across multiple biological systems underscore its value as both an experimental tool and therapeutic candidate within modern pharmaceutical innovation frameworks aligned with current regulatory standards and safety requirements.
