Exploring the Chemical and Biological Properties of 4-(4-Ethylpiperazinocarbonyl)benzylamine (CAS No. 926227-38-5)

The compound 4-(4-Ethylpiperazinocarbonyl)benzylamine (CAS No. 926227-38-5) is a synthetic organic molecule with a unique structural configuration that combines the pharmacophoric features of benzylamine and an N-substituted piperazine moiety. This hybrid architecture positions it as a promising candidate in medicinal chemistry, particularly in the design of bioactive agents targeting specific cellular pathways. The molecule’s core structure consists of a benzene ring linked via an amine group to a piperazine ring substituted at the 4-position with an ethyl chain, creating a versatile scaffold for further functionalization. Recent studies highlight its potential in modulating enzyme activity and receptor interactions, which are critical for drug development.

Recent advancements in computational chemistry have enabled researchers to predict 4-(4-Ethylpiperazinocarbonyl)benzylamine’s binding affinity to protein targets with unprecedented accuracy. A study published in Journal of Medicinal Chemistry (2023) employed molecular docking simulations to demonstrate its favorable interactions with histone deacetylase (HDAC) isoforms, particularly HDAC6. The N-ethylpiperazine fragment was found to form hydrogen bonds with key residues in the enzyme’s catalytic pocket, while the benzylamine group stabilized interactions through π-stacking effects. This dual mechanism suggests utility in epigenetic therapies, where HDAC inhibition is linked to anti-cancer and neuroprotective outcomes.

In preclinical evaluations, this compound has shown selective activity against cancer cell lines compared to normal cells. A collaborative study between institutions in Germany and Japan (published in Nature Communications, 2023) revealed that CAS No. 926227-38-5-based analogs induced apoptosis in multiple myeloma cells by upregulating pro-apoptotic genes such as BAX and downregulating BCL-2 family proteins. The ethyl substitution on the piperazine ring was critical for enhancing membrane permeability, enabling effective intracellular delivery without compromising selectivity.

Synthetic chemists have optimized the preparation of 4-(4-Ethylpiperazinocarbonyl)benzylamine, emphasizing scalable methods for pharmaceutical applications. A notable protocol involves coupling benzaldehyde with ethylenediamine under palladium-catalyzed conditions, followed by amidation with ethyl piperazine carboxylic acid derivatives. This route achieves yields exceeding 85% while minimizing byproduct formation, as reported in a 2023 issue of Tetrahedron Letters. The use of microwave-assisted synthesis further reduces reaction times, aligning with industry demands for efficient drug substance production.

Bioavailability studies underscore its favorable physicochemical properties. With a calculated logP value of 1.8 and solubility enhanced by polar amine groups, this compound exhibits optimal drug-like characteristics according to Lipinski’s “Rule of Five.” In vivo pharmacokinetic data from rodent models (published in Bioorganic & Medicinal Chemistry, 2023) indicate moderate absorption rates when administered orally, with plasma half-life extending beyond four hours due to its balanced hydrophobicity and metabolic stability.

Pioneering work from Stanford University’s Drug Discovery Lab (August 2023) identified this compound as a modulator of GABAergic neurotransmission pathways. When tested on hippocampal neurons derived from Alzheimer’s disease models, it demonstrated neuroprotective effects by inhibiting glutamate-induced excitotoxicity at submicromolar concentrations. The benzylamine backbone facilitated interaction with GABA_A receptor subunits α5β3γ_{1/α1β1γ1), while the piperazine moiety contributed to prolonged receptor occupancy compared to existing therapeutics.}

Safety profiles from recent toxicity assessments suggest low acute toxicity when administered at therapeutic doses. A comparative study published in Toxicological Sciences (July 2023) found that oral administration up to 50 mg/kg did not induce significant organ damage or mutagenicity in zebrafish embryos or HEK cell lines under Ames test conditions. However, prolonged exposure studies are ongoing to evaluate long-term effects on mitochondrial function and metabolic pathways.

Innovative applications are emerging in targeted drug delivery systems leveraging its structural flexibility. Researchers at MIT’s Department of Chemical Engineering (June 2023) conjugated it with polyethylene glycol (PEG) chains via click chemistry reactions, creating prodrugs that selectively accumulate within tumor microenvironments through pH-sensitive cleavage mechanisms. This approach addresses challenges associated with off-target effects common in conventional chemotherapy agents.

The compound’s role as a chiral building block has also gained attention following advancements reported at the European Peptide Symposium (EPS 39). Enantiomerically pure forms were synthesized using asymmetric hydrogenation catalysts containing chiral ligands derived from natural products like (-)-sparteine or (+)-DIOP derivatives, enabling exploration of stereochemical influences on biological activity without introducing regulatory concerns associated with racemic mixtures.

Ongoing research focuses on its potential as an immunomodulatory agent through TLR signaling pathway modulation identified by single-cell RNA sequencing analysis conducted at Oxford University (March 2024). Preliminary data indicates that nanomolar concentrations can suppress inflammatory cytokine production by macrophages without affecting T-cell activation profiles—a critical balance for developing anti-inflammatory drugs without compromising immune response efficacy.

Spectroscopic characterization confirms its purity across multiple analytical platforms: proton NMR spectra reveal distinct peaks corresponding to aromatic protons at δ7–8 ppm and aliphatic ethyl groups around δ1–1.5 ppm; mass spectrometry confirms an exact mass matching theoretical values within ±0.^{1 mDa tolerance windows using high-resolution QTOF instruments operated under ESI mode.}

Cryogenic electron microscopy studies published concurrently in eLife (May 2019 update series) provided atomic-resolution insights into how substituent patterns influence protein-ligand interactions when bound to kinases like Aurora A/B or CDK isoforms implicated in cancer progression mechanisms.

Solid-state form stability investigations conducted under varying humidity conditions revealed polymorphic tendencies that were mitigated through co-crystallization strategies involving organic acids such as succinic acid or maleic acid reported by researchers at ETH Zurich (, October 1st edition). These findings are crucial for maintaining consistent pharmacological performance during formulation development stages.

In vitro ADME testing using human liver microsomes demonstrated phase I metabolism primarily via cytochrome P450 enzymes CYP3A4/5 and CYP1A ,with glucuronidation serving as major phase II pathway according to data presented at SfNP Annual Meeting poster sessions last November.The resulting metabolites retained approximately half the parent compound’s biological activity suggesting possible bioactivation mechanisms worth exploring further.

Raman spectroscopy combined with machine learning algorithms has been applied successfully by teams at KAIST (, February special issue)to quantify trace amounts within complex matrices such as blood plasma or tissue extracts—critical capability for developing sensitive diagnostic assays based on this molecule’s unique vibrational signature patterns observed between ~650–1750 cm?1 range.

A recent collaboration between pharmaceutical companies Pfizer and Novartis (published here) evaluated its use as a lead compound for developing novel antiviral agents targeting SARS-CoV-PLD protease variants observed post-Omicron wave mutations.The rigid bicyclic structure provided enhanced binding affinity over existing small molecules while maintaining structural integrity under physiological pH conditions measured between pH ranges typical for endosomal compartments (~5–6). ...
