IIT Delhi researchers find method for synthesis of promising molecules for chemotherapeutic drugs

As per the team, they have demonstrated how polyarylquinones can be synthesized easily by simple relayed addition of fulvene (a five-membered ring compound) on quinones (six-membered ring structure)with the help of a Pd (Palladium metal) catalyst.

IIT Delhi researchers find new method for synthesis of promising molecules for chemotherapeutic drugs

A team of researchers at the Indian Institute of Technology (IIT) Delhi has found out a new way for easy synthesis of polyarylquinone, a promising molecule for chemotherapeutic drugs.Polyarylquinone is a molecule that is used in various industries such as pharmaceuticals, optoelectronics, and bio-imaging. However, its synthesis is often challenging and plagued with various bottleneck steps, the officials said. 

As per the team, they have demonstrated how polyarylquinones can be synthesized easily by simple relayed addition of fulvene (a five-membered ring compound) on quinones (six-membered ring structure)with the help of a Pd (Palladium metal) catalyst.

"Aryl quinones-based chemotherapeutic drugs are already present in the market, but our molecule shows a promising result by observing better cytotoxicity than previously discovered aryquinone doxorubicin drug. Since the need of the hour is to develop a technology that decreases the cost and manpower and dependence of the country on the import of active pharmaceuticals, this will open the paths for industries and ultimately benefit would pass to society," said lead researcher, Ravi P Singh, Professor, Department of Chemistry, IIT Delhi.

"The ability of man to replicate the molecules of living creatures, and create other molecules like them, is a remarkable development in human history. By employing sophisticated catalytic reactions and appropriately designed reaction processes, chemists can synthesize not only the molecules of nature and their analogues, but also countless other organic molecules for potential applications in many areas of science, technology and everyday life," he added, as reported by an English daily.

The study, published in reputed international journal ACS Catalysis, also found that "polyarylquinones" can be used as an antioxidant, in chemotherapy and optoelectronics.

Singh explained further that the researchers’ work also establishes the broad substrate scope of the reaction and delves into the mechanism of the "dehydrogenative coupling reaction". "Moreover, single-crystal X-ray diffraction reveals interesting packing motifs suggesting the suitability of these materials in optoelectronics. As a practical utilisation of the reaction, various synthesised polyarylquinones with structural diversity were screened for their redox properties and found to exhibit better antioxidant or chemotherapeutic properties,” he said.
