Spectroscopic characterization and crystal structures of two cathinone derivatives: N-ethyl-2-amino-1-phenylpropan-1-one (ethcathinone) hydrochloride and N-ethyl-2-amino-1-(4-chlorophenyl)propan-1-one (4-CEC) hydrochloride
Forensic Toxicol 2017;35(1):114-124.PMID:28127410DOI:10.1007/s11419-016-0345-6.
Comprehensive chemical characterization for two cathinone derivatives, N-ethyl-2-amino-1-phenylpropan-1-one (ethcathinone) hydrochloride and N-ethyl-2-amino-1-(4-chlorophenyl)-propan-1-one (4-chloroethcathinone, 4-CEC) hydrochloride, in material seized by drug enforcement agencies was performed by nuclear magnetic resonance (NMR) spectroscopy, infrared spectroscopy, gas chromatography-mass spectrometry in positive electron ionization mode, liquid chromatography-mass spectrometry in positive electrospray ionization mode and X-ray crystallography. The examined samples of these two compounds proved to be very pure for ethcathinone and mixed with very small quantities of other substances for 4-CEC by NMR spectroscopy and mass spectrometry. X-ray crystallographic studies confirmed the occurrence of both compounds as racemic mixtures. These spectroscopic and crystallographic data seem very useful for their identification. Especially for 4-CEC, this is the first description on its spectroscopic characterization in a scientific context to our knowledge.
The effects of N-ethyl-N'-methyl imidazolium chloride on the solubility, stability and aggregation of tc-rPA
FEBS J 2014 Apr;281(7):1738-49.PMID:24506586DOI:10.1111/febs.12736.
The ionic liquid N-ethyl-N'-methyl imidazolium chloride (EMIMCl) has been described as being very efficient in promoting refolding of the recombinant plasminogen activator rPA. Our study reveals that molar concentrations of EMIMCl increase the solubility of native and unfolded proteins due to favorable interactions with amino acid side chains rather than favorably interacting with the peptide backbone. This delicate balance of favorable interactions with side chains and unfavorable interactions with the peptide backbone provides a molecular explanation of how EMIMCl suppresses protein aggregation and simultaneously promotes refolding. By contrast, high concentrations of EMIMCl denature proteins because of a reduced water content and strong favorable interactions with amino acid side chains. This denatured species is not soluble and aggregates because, in contrast to the classical denaturants, guanidine hydrochloride and urea, EMIMCl does not solubilize the peptide backbone.

Synthesis, antimicrobial and anti-cancer activities of some new N-ethyl, N-benzyl and N-benzoyl-3-indolyl heterocycles
Acta Pharm 2012 Jun;62(2):157-79.PMID:22750815DOI:10.2478/v10007-012-0020-3.
A series of 1-(N-substituted-1H-indol-3-yl)-3-arylprop-2-ene-1-ones (2a, b-4a, b) were prepared and allowed to react with urea, thiourea or guanidine to give pyrimidine derivatives 5a, b-13a, b. Reaction of 2a, b-4a, b with ethyl acetoacetate in the presence of a base gave cyclohexanone derivatives 14a, b-16a, b. Reaction of the latter compounds with hydrazine hydrate afforded indazole derivatives 17a, b-19a, b. On the other hand, reaction of 2a, b-4a, b with some hydrazine derivatives, namely hydrazine hydrate, acetyl hydrazine, phenylhydrazine and benzylhydrazine hydrochloride, led to the formation of pyrazole derivatives 20a, b-31a, b. Moreover, reaction of 2a, b-4a, b with hydroxylamine hydrochloride gave isoxazole derivatives 32a, b-34a, b. The newly synthesized compounds were tested for their antimicrobial activity and showed that 4-(N-ethyl-1H-indol-3-yl)-6-(p-chlorophenyl)-pyrimidine-2-amine (11b) was the most active of all the test compounds towards Candida albicans compared to the reference drug cycloheximide. Eighteen new compounds, namely pyrimidin-2(1H)-ones 5a, b-7a, b, pyrimidin-2(1H)-thiones 8a, b-10a, b and pyrimidin-2-amines 11a, b-13a, b derivatives, were tested for their in vitro antiproliferative activity against HEPG2, MCF7 and HCT-116 cancer cell lines. 4-(N-ethyl-1H-indol-3-yl)-6-(p-methoxyphenyl)-pyrimidin-2-amine (11a) was found to be highly active with IC(50) of 0.7 μmol L⁻¹.
Noradrenergic neurotoxin, N-(2-chloroethyl)-N-ethyl-2-bromobenzylamine hydrochloride (DSP-4), treatment eliminates estrogenic effects on song responsiveness in female zebra finches (Taeniopygia guttata)
Behav Neurosci 2008 Oct;122(5):1148-57.PMID:18823170DOI:10.1037/0735-7044.122.5.1148.
Female songbirds use male songs as an important criterion for mate selection. Several studies have reported that female songbirds prefer complex songs to other song types. In a recent study, the authors found that song responsiveness in female zebra finches (Taeniopygia guttata) is strongly modulated by circulating estrogen levels. The behavioral effects of estrogen are often mediated via norepinephrine (NE). The current study administered the noradrenergic neurotoxin, N-(2-chloroethyl)-N-ethyl-2-bromobenzylamine hydrochloride (DSP-4) to estradiol-treated female zebra finches to investigate if estrogenic effects on song responsiveness are mediated via NE. The authors tested song responsiveness of adult female zebra finches for three acoustically different song types--simple, long-bout, and complex--under three treatment conditions, untreated, estradiol-treated, and estradiol + DSP-4-treated. Females only showed differential song responsiveness when treated with estradiol alone, responding more to complex songs. DSP-4 treatment eliminated this differential responsiveness. The results are discussed in the light of evidence from functional, neurochemical, and neuroanatomical studies that suggest that estrogenic effects on song processing might be mediated by NE.
Long-term effects of N-2-chlorethyl-N-ethyl-2-bromobenzylamine hydrochloride on noradrenergic neurones in the rat brain and heart
Br J Pharmacol 1976 Dec;58(4):521-7.PMID:1000130DOI:10.1111/j.1476-5381.1976.tb08619.x.
1 N-2-Chlorethyl-N-ethyl-2-bromobenzylamine hydrochloride (DSP 4) 50 mg/kg intraperitoneally, produced a long-term decrease in the capacity of brain homogenates to accumulate noradrenaline with significant effect 8 months after the injection. It had no effect on the noradrenaline uptake in homogenates from the striatum (dopamine neurones) and on the uptake of 5-hydroxytryptamine (5-HT) in various brain regions. 2 In vitro DSP 4 inhibited the noradrenaline uptake in a cortical homogenate with an IC50 value of 2 muM but was more than ten times less active on the dopamine uptake in a striatal homogenate and the 5-HT uptake in a cortical homogenate. 3 DSP 4 (50 mg/kg i.p.) inhibited the uptake of noradrenaline in the rat heart atrium in vitro but this action was terminated within 2 weeks. 4 DSP 4 (50 mg/kg i.p.) cuased a decrease in the dopamine-beta-hydroxylase (DBH) activity in the rat brain and heart. The onset of this effect was slow; in heart a lag period of 2-4 days was noted. In brain the DBH-activity in cerebral cortex was much more decreased than that in hypothalamus which was only slightly affected. A significant effect was still found 8 months after the injection. The noradrenaline concentration in the brain was greatly decreased for at least two weeks, whereas noradrenaline in heart was only temporarily reduced. 5 The long-term effects of DSP 4 on the noradrenaline accumulation, the DBH activity and noradrenaline concentration in the rat brain were antagonized by desipramine (10 mg/kg i.p.). 6 It is suggested that DSP 4 primarily attacks the membranal noradrenaline uptake sites forming a covalent bond and that the nerve terminals, as a result of this binding, degenerate.
