Chikungunya is a re-emerging viral infection of worldwide concern, and new antiviral therapeutics are necessary to combat this disease. Inhibitors of the non-structural protein 1 (NsP1), which shows Methyltransferase (MTase) activity and plays a crucial in the Chikungunya virus (ChikV) replication, are exhibiting promising results. This review aimed to describe recent advances in the development of NsP1 inhibitors for the treatment of Chikungunya disease. High-throughput screening of novel ChikV NsP1 inhibitors has been widely performed for the identification of new molecule hits through fluorescence polarization, Western blotting, ELISA-based assay, and capillary electrophoresis assays. Additionally, cell-based assays confirmed that the inhibition of ChikV NsP1 abolishes viral replication. In summary, pyrimidine and pyrimidin-7(6H)-one derivatives, GTP and nucleoside analogs have been demonstrated to show inhibitory activity and are considered promising scaffolds that provide useful knowledge for the research and development of new NsP1 inhibitors as potential treatment of Chikungunya re-emerging disease.

Cancer remains a primary cause of death globally, and effective treatments are still limited. While chemotherapy has notably enhanced survival rates, it brings about numerous side effects. Consequently, the ongoing challenge persists in developing potent anti-cancer agents with minimal toxicity. The versatile nature of the quinazoline moiety has positioned it as a pivotal component in the development of various antitumor agents, showcasing its promising role in innovative cancer therapeutics. This concise review aims to reveal the potential of quinazolines in creating anticancer medications that target histone deacetylases (HDACs).

Triazine is an important pharmacophore in the field of research for the development of novel medications due to its presence in numerous powerful physiologically active compounds with significant medical potential, such as anti-tumor, anti-viral, anti-inflammatory, anti-microbial, anti-HIV, anti-leishmanial and others. The easy availability of triazine, high reactivity, simple synthesis of their analog, and their notable broad range of biological activities have garnered chemist interest in designing s-triazine-based drugs. The interest of medicinal chemists has been sparked by the structure-activity relationship of these biologically active entities, leading to the discovery of several promising lead molecules. Its importance for medicinal chemistry research is demonstrated by the remarkable progress made with triazine derivatives in treating a variety of disorders in a very short period. Authors have collated and reviewed the medicinal potential of s-triazine analogous to afford medicinal chemists with a thorough and target-oriented overview of triazine-derived compounds. We hope the present compilation will help people from the industry and research working in the medicinal chemistry area.
