Uses

Used in Pharmaceutical Industry:
5-Bromothieno[2,3-d]pyrimidin-4-amine is used as a key intermediate in the synthesis of Imidazolidinone derivatives. These derivatives have been identified as potent inhibitors of the protein kinase R (PKR)-like endoplasmic reticulum kinase (PERK), which plays a crucial role in the unfolded protein response (UPR). PERK inhibition has been shown to be beneficial in the treatment of various diseases, including neurodegenerative disorders, metabolic diseases, and certain types of cancer.
In the preparation of Imidazolidinone derivatives, 5-Bromothieno[2,3-d]pyrimidin-4-amine serves as a valuable starting material due to its unique structural features and reactivity. The bromine atom at the 5th position can be easily replaced with other functional groups, while the amine group at the 4th position can be used for further functionalization and diversification of the molecule. This allows for the development of a wide range of Imidazolidinone derivatives with varying potencies and selectivities against PERK, ultimately leading to the discovery of more effective therapeutic agents for the treatment of various diseases.

Discovery of a new series of naphthamides as potent VEGFR-2 kinase inhibitors

Inhibition of VEGFR-2 signaling pathway has already become one of the most promising approaches for the treatment of cancer. In this study, we describe the design, synthesis, and biological evaluation of a new series of naphthamides as potent inhibitors of VEGFR-2. Among these compounds, 14c exhibited high VEGFR-2 inhibitory potency in both enzymatic and HUVEC cellular proliferation assays, with IC50 values of 1.5 and 0.9 nM, respectively. Kinase selectivity profiling revealed that 14c was a multitargeted inhibitor, and it also exhibited good potency against VEGFR-1, PDGFR-β, and RET. Furthermore, 14c effectively blocked tube formation of HUVEC at nanomolar level. Overall, 14c might be a promising candidate for the treatment of cancer.
