Lead identification and optimization is always a challenge to the medicinal chemists in drug discovery. Numbers of simple to complex and smaller to bigger organic compounds are prepared to meet the screening purpose of biological targets. Conventional solution phase synthetic methodologies are lacking the speed to run along with the need of medicinally(More)
An efficient, microwave-assisted method for the liquid-phase combinatorial synthesis of 3,5-disubstituted thiohydantoins and 3,5-disubstituted 2-thioxotetrahydropyrimidin-4-ones has been developed. In synthesizing thiohydantoins, Fmoc-protected amino acids were coupled with polymer support and then deprotected to give primary amines. While in synthesizing(More)
Liquid phase combinatorial synthesis (LPCS) of piperazinediones by the use of soluble polymer support is explored to generate libraries. Proline anchored polyethylene glycol monomethyl ether (PEG) underwent dipeptide formation with different Fmoc-amino acids in the presence of dicyclohexyl carbodiimide (DCC). Deprotection of Fmoc accompanied with the(More)
