“…Compound 58d reduced parasitemia by more than 99.8% when administered orally (50 mg/kg once daily for 4 days). This administration scheme led to a mean survival time of 23 González Cabrera et al were interested in similar derivatives but including an amine function at position 4 of the thienopyrimidine core [35,54]. A SAR study demonstrated the influence of various substituents at positions 2, 4, and 6 of the thieno [3,2-d]pyrimidine ring (Table 5).…”

Thienopyrimidines are widely represented in the literature, mainly due to their structural relationship with purine base such as adenine and guanine. This current review presents three isomers—thieno[2,3-d]pyrimidines, thieno[3,2-d]pyrimidines and thieno[3,4-d]pyrimidines—and their anti-infective properties. Broad-spectrum thienopyrimidines with biological properties such as antibacterial, antifungal, antiparasitic and antiviral inspired us to analyze and compile their structure–activity relationship (SAR) and classify their synthetic pathways. This review explains the main access route to synthesize thienopyrimidines from thiophene derivatives or from pyrimidine analogs. In addition, SAR study and promising anti-infective activity of these scaffolds are summarized in figures and explanatory diagrams. Ligand–receptor interactions were modeled when the biological target was identified and the crystal structure was solved.

Inflammation is an essential body immune system response against various infections and tissue injuries and maintains normal homeostasis. Alterations in inflammatory responses lead to multiple disorders like heart diseases, obesity, diabetes, cancer, stroke, and neurodegenerative disorders. Cyclooxygenases (COXs), the enzymes, exist in two isoforms (COX‐1 and COX‐2) that catalyze the rate‐determining step of prostaglandin biogenesis and play a significant role in inflammation. COX‐2 inhibitors, although effective anti‐inflammatory agents are considered to be highly unsafe for long‐term usage due to their possible side and adversative effects. Recently, fused‐thienopyrimidines have emerged as a privileged scaffold with excellent anti‐inflammatory potential. In the present review, we have emphasized the recent developments in the design and synthetic strategies of fused‐thienopyrimidine derivatives and their detailed structure‐activity‐relationship (SAR) studies. The primary goal of this review is to provide restructuring knowledge about this template, which could prove beneficial and valuable for chemists working in the anti‐inflammatory area.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
