Synthesis of Novel Pyrazolopyranopyrimidine Acyclic Nucleosides Disubstituted at N2/C5 as Potential Anti-SARS-CoV-2 Inhibitors: Structural Characterization, and In Silico Studies
Nitrogen-rich heterocycles constitute privileged structural motifs in natural products and pharmaceuticals, forming the core architecture of numerous bioactive alkaloids, antibiotics, and approved drugs through their selective interactions with diverse biological targets. Among these, the imidazo[1,2-a] pyrimidine scaf...
The ongoing emergence of SARS-CoV-2 mutations underscores the urgent need for new antivirals that target key viral proteins. This study describes the design, synthesis, and evaluation of two series of 1,3,4-oxadiazole-tethered N-substituted isatin hybrids as inhibitors of the SARS-CoV-2 main protease (Mpro): 1,2,3-tria...

The persistent global threat posed by emerging and re-emerging RNA viruses, including SARS-CoV-2, influenza A(H1N1)pdm09, DENV-2, and CHIKV, highlights the critical need for novel and broad-spectrum antiviral agents. Building upon the established antiviral activity of the quinoline scaffold, this study employed a molec...

Pyrimidine and furo[2,3-d]pyrimidine derivatives have emerged as promising anticancer agents that act through multiple mechanisms, including modulation of downstream signaling pathways such as a JAK2/STAT3 cascade. Herein, we report the synthesis of novel pyrimidine- and furo[2,3-d]pyrimidine-isoxazole hybrids via base...
