Review Of Semicarbazone, Thiosemicarbazone, And Their Transition Metal Complexes, And Their Biological Activities

Abstract

Semicarbazides and thiosemicarbazide condense to form the chemicals semicarbazones and thiosemicarbazones. Using the appropriate aldehydes or ketones with thiosemicarbazide. They are effective synthesis-related intermediates for they are widely employed in the field of medicinal chemistry since they are both pharmaceutical and bioactive compounds. One of the most important goals in medicinal and bioinorganic chemistry is the creation of novel, advantageous bioactive molecules with a variety of biological functions. Antibacterial, antifungal, antioxidant, antiviral, radical scavenger, antitubercular, anticancer, and other properties of semicarbazones, thiosemicarbazones, and their derivatives have been studied. Therapies against cancer, particularly when bound to transition metals. Their capacity to combine with metals to create chelates is thought to be related to their biological actions. The compound’s IR and 1H-NMR data have been used to characterize their structures. Studies have been done on substances with the formulae -N=N-, -N-C=S, and the pharmacophore is -CH=N-. To organize the various biological activities of some synthesized semicarbazone and thiosemicarbazone derivatives with transition metals, the synthetic root of some of these derivatives and complexes are reviewed as for biological activities in accordance with this biological potential.
