Abstract:Microwave radiation is used as a heating source during the synthesis of heterocyclic
compounds. The heating mechanisms involved in microwave-induced synthesis include
dipolar polarization and ionic conduction. This heating technology follows the green
protocol as it involves the use of recyclable organic solvents during synthesis. The microwave
heating approach offers a faster rate of reaction, easier work-up procedure, and
higher product yield with purity and also reduces environmental pollution. So, microwave
heating is applied as a sustainable technology for the efficient production of pyrimidine
compounds as one of the heterocyclic moieties. Pyrimidine is a six-membered nitrogenous
heterocyclic compound that plays a significant role due to several therapeutic applications.
This moiety acts as an essential building block for generating drug candidates with diverse
biological activities, including anti-cancer (capecitabine), anti-thyroid (propylthiouracil),
antihistaminic (pemirolast), antimalarial (pyrimethamine), antidiabetic (alloxan), antihypertensive
(minoxidil), anti-inflammatory (octotiamine), antifungal (cyprodinil), antibacterial
(sulfamethazine), etc. This review is focused on the synthesis of pyrimidine analogs
under microwave irradiation technique and the study of their therapeutic potentials.
