WebNov 6, 2024 · Following these principles, a new class of pseudo-natural products was designed, termed chromopynones as they consist of a chromane and a tetrahydropyrimidinone fragment. Biological investigations of the chromopynones revealed a restriction in the increased uptake of glucose in cancer cells. WebPseudo NPs retain the biological relevance of NPs, yet exhibit novel structures not accessible to nature through existing biosynthesis pathways and promise to show novel bioactivity. We had demonstrated successful applications of this concept with the Chromopynones, [1] Indomorphans, [2] Indotropanes, [3] as well as …

However, this seven-transmembrane helical G protein-coupled … WebMar 1, 2024 · For example, chromopynone 19 and indomorphan 34 pseudo-NPs such as 77 and 75 (Figure 4) were identified as highly potent inhibitors of glucose uptake by targeting the glucose transporters GLUT1 and GLUT3. Both are unprecedented chemotypes for GLUT inhibition.
WebThe objectives of this research work were focused on improving fermentative H2 production using mixed cultures. Using pure cultures in large scale production facilities would require extensive maintenance and operational costs. Webchromopynones define a truly novel, structurally unprecedented glucose uptake inhibitor chemotype that selectively targets glucose transporters GLUT-1 and …
WebTo arrest these trends, the logic of seeking new bioactive agents with enhanced natural mimicry is considered; notably that molecules constructed by proteins (enzymes) are more likely to interact with other proteins (e.g., targets and transporters), a notion validated by natural products.
