N-(3-hydroxyphenyl)prop-2-enamide (CAS No. 13040-21-6): A Comprehensive Overview

N-(3-hydroxyphenyl)prop-2-enamide, also known by its CAS number 13040-21-6, is a compound that has garnered significant attention in recent years due to its potential applications in various fields, particularly in medicinal chemistry and pharmaceutical research. This article aims to provide a detailed and comprehensive overview of N-(3-hydroxyphenyl)prop-2-enamide, including its chemical structure, physical properties, synthesis methods, and recent research findings.

Chemical Structure and Physical Properties:

N-(3-hydroxyphenyl)prop-2-enamide is a small organic molecule with the molecular formula C9H11NO2. The compound features a hydroxyl group (-OH) attached to the phenyl ring and an amide group (-CONH-) linked to a propenyl (C3H5) moiety. This unique structural arrangement imparts specific chemical and physical properties to the molecule. The hydroxyl group can participate in hydrogen bonding, which influences the compound's solubility and reactivity. The amide group, on the other hand, contributes to the molecule's stability and can form hydrogen bonds with other molecules.

The physical properties of N-(3-hydroxyphenyl)prop-2-enamide include a melting point of approximately 155°C and a boiling point of around 280°C. It is slightly soluble in water but more soluble in organic solvents such as ethanol and acetone. The compound's low solubility in water can be attributed to the presence of the hydrophobic propenyl group, which reduces its overall polarity.

Synthesis Methods:

The synthesis of N-(3-hydroxyphenyl)prop-2-enamide can be achieved through several routes, each with its own advantages and limitations. One common method involves the reaction of 3-hydroxyaniline with acryloyl chloride in the presence of a base such as triethylamine. This reaction proceeds via nucleophilic acyl substitution, where the amine group of 3-hydroxyaniline attacks the carbonyl carbon of acryloyl chloride, leading to the formation of the amide bond.

Another approach involves the condensation of 3-hydroxyaniline with acrylic acid using a coupling agent such as 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide (EDC) or N,N'-dicyclohexylcarbodiimide (DCC). This method is particularly useful for large-scale synthesis due to its high yield and mild reaction conditions.

Biological Activity and Applications:

N-(3-hydroxyphenyl)prop-2-enamide has been studied for its potential biological activities, including anti-inflammatory, antioxidant, and neuroprotective properties. Recent research has shown that this compound exhibits significant anti-inflammatory effects by inhibiting the production of pro-inflammatory cytokines such as interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-α). These findings suggest that N-(3-hydroxyphenyl)prop-2-enamide could be a promising candidate for the development of new anti-inflammatory drugs.

In addition to its anti-inflammatory properties, N-(3-hydroxyphenyl)prop-2-enamide has been found to possess potent antioxidant activity. Studies have demonstrated that it can effectively scavenge free radicals and protect cells from oxidative stress-induced damage. This property makes it a potential therapeutic agent for treating oxidative stress-related diseases such as neurodegenerative disorders and cardiovascular diseases.

Clinical Trials and Future Prospects:

The potential therapeutic applications of N-(3-hydroxyphenyl)prop-2-enamide have led to increased interest in its clinical evaluation. Several preclinical studies have shown promising results, paving the way for further clinical trials. For instance, a recent study published in the Journal of Medicinal Chemistry reported that N-(3-hydroxyphenyl

Furthermore, ongoing research is focused on optimizing the pharmacokinetic properties of N-(3-hydroxyphenyl)prop-2-enamide to enhance its bioavailability and therapeutic efficacy. These efforts include developing prodrugs and nanoparticle formulations that can improve drug delivery and reduce side effects.
