By reaction of 1,3,4-thiadiazol-2,5-dithiol with different organohalogens, chlorides of carboxylic acids, acrylic acid derivatives, alkaloids, and secondary amines, various derivatives of 2,5-bi-substituted 1,3,4-thiadiazole were synthesized, and biological properties of some of them were studied.

As a result of complex chemical processing of medicinal raw materials of Artemisia glabella Kar. et Kir., including CO2 extraction and lactones isolation, we have investigated the chemical composition of flavonoids to select the biologically active ones and carry out modifications on their basis. Two flavonoids pectolinaringenin and cirsilineol have been isolated by partition chromatography from the secondary raw materials of Artemisia glabella Kar. et. Kir. and identified. To obtain new biologically active compounds, we have synthesized new amino derivatives of cirsilineol by the Mannich reaction with secondary amines (piperidine and N-methylpiperazine) in isopropanol with the presence of dimethylaminopyridine. In proton NMR spectrum of the synthesized compounds there are proton signals of the initial cirsilineol fragment; however, there is no N-8 proton signal, besides other signals typical for amines’ benzene ring have been observed at 1.53–3.90 ppm. It means that reaction occurred at the C-8 position of carbon in ring A. The synthesized compounds have been studied for various types of biological activity typical for this class, including hepatoprotective and anti-inflammatory activities. Amino derivatives of cirsilineol exhibit a moderate activity against HepG2 cell line, while cirsilineol at a dose of 5 mg/ml expresses a pronounced hepatoprotective activity. Moreover, all samples at a dose of 25 mg/kg show poor anti-inflammatory effects on the model of acute exudative reaction in vivo.

Heterocyclic compounds are well known for their different biological activity. The heterocyclic analogs are the building blocks for synthesis of the pharmaceutical active compounds in the organic chemistry. These derivatives show various type of biological activity like anticancer, antiinflammatory, anti-microbial, anti-convulsant, anti-malarial, anti-hypertensive, etc. From the last decade research showed that the quinoline analogs plays a vital role in the development of newer medicinal active compounds for treating various type of disease. Quinoline reported for their antiviral, anticancer, anti-microbial and anti-inflammatory activity. This review will summarize the various synthetic approaches for synthesis of quinoline derivatives and to check their biological activity. Derivatives of quinoline moiety plays very important role in the development of various types of newer drugs and it can be used as lead compounds for future investigation in the field of drug discovery process.
