A class of organosulfur compounds known as thiosemicarbazones is identified by the functional group R1R2C=N-NH-CS-NR3R4, where R1, R2, R3, and R4 might be aryl, alkyl, or hydrogen groups. Thiosemicarbazide condenses with aldehydes or ketones to produce these molecules. Because of its many pharmacological characteristics, such as their antiviral, antibacterial, antifungal, anticancer, and anti-inflammatory effects, thiosemicarbazones have garnered a lot of interest. Thiosemicarbazones interact with a range of biological targets due to their molecular structure. Of particular note is their capacity to form stable compounds with metal ions. Medicinal chemistry uses this feature to create metal-based medications, where the metal-thiosemicarbazone combination can increase the drug's bioavailability and effectiveness. For example, because it inhibits ribonucleotide reductase, an enzyme essential for DNA synthesis and repair, the thiosemicarbazone derivative Triapine has been intensively explored for its potential as an anticancer drug. Additionally, thiosemicarbazones have a wide range of antibacterial activity. Their mode of action frequently entails the rupture of microbial cell membranes or the suppression of vital enzymes in microbial metabolism. This renders them formidable contenders for the creation of novel antibiotics, particularly in a time when antibiotic resistance is becoming an increasingly pressing issue.Furthermore, thiosemicarbazones appear to be promising in the treatment of viruses. It has been discovered that some derivatives prevent the growth of viruses like the hepatitis C virus, herpes simplex virus, and HIV. It is believed that the antiviral activity results from blocking viral enzymes or preventing viruses from entering host cells. Thiosemicarbazones are used in analytical chemistry for metal ion detection and quantification in addition to its medicinal uses. Their capacity to create colorful complexes with metals renders them valuable as reagents in electrochemical and spectrophotometric experiments.To sum up, thiosemicarbazones are adaptable substances with a variety of uses in analytical and therapeutic chemistry. They are useful instruments in the development of novel medicinal drugs and diagnostic techniques due to their distinct chemical characteristics and biological activity. They are still being studied in order to fully realize their potential in a variety of scientific and medical domains.
