Antidepressant Activity of Euparin: Involvement of Monoaminergic Neurotransmitters and SAT1/NMDAR2B/BDNF Signal Pathway

Depression is the most significant risk factor for suicide, yet the causes are complex and disease mechanism remains unclear. The incidence and disability rate of depression are very high and the efficacy of some traditional antidepressants is not completely satisfactory. Recently, some studies have found that benzofurans have anti-oxidation and anti-monoamine oxidase properties, which are related to depression. Euparin is a monomer compound of benzofuran, previous work by our team found that it improves the behavior of depressed mice. However, additional antidepressant effects and mechanisms of Euparin have not been reported. In this study, the Chronic Unpredictable Mild Stress (CUMS) model of mice was used to further investigate the effect and mechanism of Euparin on depression. Results showed that Euparin (8, 16 and 32 mg/kg) reduced depression-like behavior in mice compared with the model group. Meanwhile, all doses of Euparin were found to increase the contents of monoamine neurotransmitter and decrease monoamine oxidase and reactive oxygen species (ROS) levels in brain of depression mice. Additionally, Euparin restored CUMS-induced decrease of Spermidine/Spermine N1-Acetyltransferase 1 (SAT1), N-methyl-D-aspartate receptor subtype 2B (NMDAR2B) and brain derived neurotrophic factor (BDNF) expression. These findings demonstrate that Euparin has antidepressant properties, and its mechanism involves the SAT1/NMDAR2B/BDNF signaling pathway.

Small molecules targeting HIF-1 alpha pathway for cancer therapy in recent years

Hypoxia is a very important feature of tumors, especially for solid tumors, and it was demonstrated highly relevant with aggressive biology, including anti-apoptosis, vasculogenesis and radiation or chemotherapy resistance. Correlatively, hypoxia-inducible factors 1-alpha (HIF-1 alpha), which the wildest contribution of hypoxia-inducible factors (HIFs), plays a crucial role in the adaptation of tumor cells to hypoxia via upregulating the transcription of the oncogene and downregulating the transcription of suppressor gene. This review focus on the HIF-1 alpha regulation including hydroxylation and acetylation, growth factors pathway, heat shock proteins(HSPs), and small molecule inhibitors for HIF-1 alpha directly or indirectly.

Unusual structural changes as a result of weathering benzofuran-based diarylethenes in simulated sunlight

While the products that result from photochemical degradation of thiophene-based diarylethenes have been documented, those from the benzofuran counterparts have been less extensively studied. In this article, we present two unusual and yet to be reported degradation products of a dialkoxybenzofuran derivative, characterized by a combination of spectroscopy techniques and X-ray crystallography. We show that these products are generated by due to the specific substitution position of the alkoxy groups on the benzofuran heterocycle. We also propose reasonable mechanisms for the degradation pathways and products formation, which are supported by equivalent studies using isomeric monoalkoxy versions.

CHEMICAL COMPOSITION OF BIOLOGICAL ACTIVE EXTRACTS OF Tapirira guianensis (ANACARDIACEAE)

This work describes the chemical composition of MeOH seeds and flowers extracts of Tapirira guianensis, a known tree that occurs in the Brazilian Atlantic forest. The CH2Cl2 soluble fraction of seeds extract was submitted to chromatographic procedures to obtain a mixture of new alkenyl dihydrobenzofuranoids which were identified as 2-[(10’Z)-dodec-10′-enyl]-dihydro-1-benzofuran-5-ol, 2-[(10’Z)-tridec-10′-enyl]-dihydro-1-benzofuran-5-ol e 2-[(10’Z)-pentadec-10′-enyl]-dihydro-1-benzofuran-5-ol (1 – 3) besides ss-sitosterol. From the EtOAc soluble fraction of flowers MeOH extract quercetin, quercitrin and gallic acid were obtained by chromatographic techniques. The fatty acid composition of oils from leaves and seeds were also determinate and the leaves’ oil is composed by 63.94% of saturated and 36.04% of unsaturated fatty acids while in the seeds the oil present 42.13% of saturated and 57.87% of unsaturated. All compounds and derivatives were identified by their spectrometric data analysis. The brine shrimp test of the extracts showed the seed CH2Cl2 and the EtOAc and BuOH soluble fractions of the flowers were actives and, the alkyl phenols are the responsible for this moderate activity. The antioxidant tests of the extracts indicated EtOAc soluble fraction of MeOH extract of flowers showed better results possibly due the presence of flavonoids and gallic acid.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 4412-91-3, you can contact me at any time and look forward to more communication. Formula: C5H6O2.

Benzofuran-isatin hybrids and their in vitro anti-mycobacterial activities against multi-drug resistant Mycobacterium tuberculosis

A series of benzofuran-isatin hybrids 6a-n and 7a-g linked by alkyl linkers were designed and synthesized. Among them, hybrids 6a-1 and 7a-g were assessed for their in vitro anti-mycobacterial activities against two multi-drug resistant Mycobacterium tuberculosis (MDR-MTB) strains and the cytotoxicity towards CHO cells. The preliminary results indicated that all hybrids (MIC: 0.125-16 mu g/mL) showed excellent activity against the tested MDR-MTB strains, and low cytotoxicity (CC50: 64->512 mu g/mL) towards CHO cells. Among them, hybrid 7e (MIC: 0.125 and 0.25 mu g/mL) was highly active against the tested two MDR-MTB strains, which was 8-16 folds better than ciprofloxacin (MIC: 1 and 4 mu g/mL), >= 512 folds more potent than rifampicin (MIC: 64 and > 128 mu g/mL) and isoniazid (MIC: >128 mu g/mL), but it was less active than TAM16 (MIC: <0.06 mu g/mL). Moreover, the hybrid 7e (CC50: 128 mu g/mL) also showed low cytotoxicity towards CHO cells, and high selectivity index (1,024). However, the metabolic stability and in vivo pharmacokinetic profiles of hybrid 7e were inferior to TAM16, so it still needs to be modified so as to get the optimized hybrid for potential use in mycobacterial treatment.

A benzofuran-beta-alaninamide based turn-on fluorescent chemosensor for selective recognition of Fe3+ ions

A benzofuran-beta-alaninamide based chemosensor, 3-(3-((4-methylbenzyl)amino)propanamido)benzofuran-2-carboxamide (BAA), was designed and synthesized for selective detection of Fe3+ ions. The binding ability of BAA towards Fe3+ in DMSO/H2O solution (9/1, v/v) has been studied by UV-vis absorption and fluorescence spectroscopy. Interestingly, the probe BAA exhibits an excellent turn-on fluorescence enhancement at 424 nm with an excitation wavelength of 290 nm. The quantum yield was determined to be 0.248 for BAA and 0.447 for the iron complex. The limit of detection (LOD) was calculated to be 1.3 mu M and 0.067 mu M by UV-vis absorption and fluorescence methods respectively. These values are much lower than that of US Environmental Protection Agency guidelines for drinking water (5.37 mu M). Job’s plot measurement evidenced the 2 : 1 binding stoichiometry for the complex formed between BAA and Fe3+. Moreover, the binding interaction of BAA towards Fe3+ was confirmed by density functional theory (DFT) studies. Finally, the real sample analysis proved that the probe BAA was more suitable for the detection of Fe3+.
