Method for quickly detecting doping of benzodiazepine compound in food, medicine or health-care product

InactiveCN101718787ABroad target coverageCompliant with Regulatory Application RequirementsMaterial analysisPretreatment methodScreening method
The invention discloses a method for quickly detecting the doping of a benzodiazepine compound in a food, a medicine or a health-care product. The method comprises the following steps: firstly, preprocessing a sample to be measured, extracting the benzodiazepine compound which is added in an enriched transgression way and then combining with a colloidal gold immunological chromatographic method, thereby realizing the quick detection of the benzodiazepine compound added into the food, the medicine or the health-care product.The invention features wide coverage range of measured targets, simple operation, high detection speed and easy observation of a detection result, can realize the quick screening of a large number of samples, picks out the samples added with the benzodiazepine compound in a transgression way from a large number of samples, lowers the cost greatly and reduces the workload.The preprocessing method can effectively enrich the concentration of a substance to be measured, so the detection result is more sensitive and accurate.The invention is suitable for various common medicament forms in the food, the medicine or the health-care product, can fill up a system screening method which is absent in the industry, executes the supervision and control over the food and medicine market effectively and guarantees the safety of the diet and medicine of people.

Improved process for preparing thieno-benzodiazepine compounds

The invention relates to a method for preparing a thieno-benzodiazepine compound. The following main steps are that the thieno-benzodiazepine compound is prepared by a compound as shown in the formula (2) and a compound as shown in the formula (3) by carrying out condensation reaction, reduction reaction and cyclization reaction in sequence; the method is characterized in that i) the reducer adopted in the reduction reaction can be Fe, FeSO4, Zn, Na2S, Na2S2 or NaHS; ii) before the reduction reaction is carried out, the unreacted compound as shown in the formula (2) needs to be removed. The preparation method has the advantages of simple and easy operation (facilitating commercial preparation), moderate reaction conditions, low preparation cost of the products, high purity and yield of the products, and so on. The preparation method lays a foundation for the enhancement of the commercial preparation of the ultimate products which take the thieno-benzodiazepine compound prepared by the invention as an intermediate.

Method for catalytically preparing benzodiazepine compound by using titanocene dichloride

The invention discloses a method for catalytically preparing a benzodiazepine compound by using titanocene dichloride. According to the method, a 3-butyne-2-ketone compound and an o-phenylenediamine compound are taken as raw materials, ethanol or methanol is taken as a solvent and an accelerant, titanocene dichloride is taken as a catalyst, and isophthalic acid and 2-hydroxy nicotinic acid or salicylic acid is taken as a ligand to high efficiently prepare the 2,4-diphenyl-3-H-1,5-benzodiazepine derivative in a high-yield mode. The usage amount of the catalyst used in the method is low, and the catalyst is low in price, is free of toxicity and is stable in air; the reaction is mild in conditions, short in time and simple in operation; and after the reaction is finished, only simple column chromatography separation is needed to be carried out on the product to obtain the 2,4-diphenyl-3-H-1,5-benzodiazepine derivative. A novel low-cost green and efficient way is developed for preparation of the 2,4-diphenyl-3-H-1,5-benzodiazepine derivative, and the method has a wide application prospect.
