6 results about "Reuptake" patented technology

Reuptake is the reabsorption of a neurotransmitter by a neurotransmitter transporter located along the plasma membrane of an axon terminal (i.e., the pre-synaptic neuron at a synapse) or glial cell after it has performed its function of transmitting a neural impulse.

Novel alkaloid compound Oreonudine C as well as preparation method and application thereof

The invention discloses a compound with remarkable 5-hydroxytryptamine (5-HT) reuptake inhibition activity, a preparation method of the compound and application of the compound in preparation of anti-depression drugs. And the compound is a compound Oreonudine C. The invention further discloses a preparation method of the compound. The preparation method of the Oreonudine C comprises the following steps: extracting with 95% ethanol, acidifying the extract, extracting with petroleum ether, adjusting the acid water layer to be alkaline with alkali liquor, extracting with chloroform, and performing silica gel column chromatography, C18 ODS column chromatography and preparative high performance liquid chromatography on the chloroform extraction part to obtain the Oreonudine C. The invention further discloses a preparation method of the Oreonudine C. The preparation method of the Oreonudine C comprises the following steps: extracting with 95% ethanol, acidifying the extract, extracting with petroleum ether, adjusting the acid water layer to be alkaline with alkali liquor, and obtaining the Oreonudine C. In-vitro experiments show that the compound Oreonudine C remarkably inhibits reabsorption of 5-HT (the inhibition rate is 60.4%) in mouse hippocampal neuronal cells HT22, and the inhibition rate of the compound Oreonudine C is superior to that of a positive control drug amitriptyline (the inhibition rate is 53.6%). The invention provides an important candidate compound for developing efficient and novel antidepressant drugs.

Novel alkaloid compound Oreonudine F as well as preparation method and application thereof

The invention discloses a compound with remarkable noradrenaline (NE) reuptake inhibition activity and application of the compound in preparation of an anti-depression drug. The compound is a compound Oreonudine F. The preparation method of the compound comprises the following steps: extracting an overground part of wild poppy by using 95% ethanol, acidifying an extract, extracting by using petroleum ether, adjusting an acid water layer to be alkaline by using alkali liquor, and extracting by using chloroform. The chloroform extraction part is subjected to silica gel column chromatography, C18 ODS column chromatography, preparative high performance liquid chromatography separation and the like, and the compound Oreonudine F is obtained. In-vitro activity test results show that the compound Oreonudine F significantly inhibits reabsorption of NE (the inhibition rate is 45.6%) in mouse hippocampal neuronal cells HT22, and the inhibition rate of the compound Oreonudine F is superior to that of a positive control drug amitriptyline (the inhibition rate is 35.5%). The invention provides an important candidate compound for developing efficient and novel antidepressant drugs.
