title: Pyrimidine-fused Derivatives: Synthetic Strategies and Medicinal Attributes.
abstract: Pyrimidine-fused derivatives traits the inextricable part of DNA and RNA, exhibit indispensable role in numerous biological processes, possessing momentous chemical and biological importance. Pyrimidine-condensed derivatives as the pharmacophore exhibit broad spectrum of biological activities encompassing antitubercular, antibacterial, antifungal, antiviral, anti-inflammatory, antimalarial, anticancer and anti-HIV. Several retrosynthetic approaches, are available for the synthesis of pyrimidine-fused analogues which offers enormous scope in the field of medicinal chemistry. Ring fused pyrimidine and their innumerable derivatives continue to hold the attention of chemists since their presence in the biologically active resources have been known to elicit additive effects on the bio-efficacy of the molecules. The present review is a concerted effort to congregate information mainly focusing on the comprehensive categorization of pyrimidine ring based on their fusion with five, six, seven and eight-membered ring(s). Moreover, it also puts forward their systematic nomenclature, synthetic strategies, and bioactivities including SAR studies. This review is being put forwarded with an incentive to provide researchers with a comprehensive and updated literature. In addition, the manuscript also brings to light the various pharmacophore designs based on fusedpyrimidine ring system, delving deeper into synthesis and the subsequent generation of new libraries of pyrimidine-fused derivatives including their biological assessments.
