Fusion heterocyclic compounds have various biological activities, such as anticancer, antibacterial, antifungal and anti-inflammatory, and thus have been widely used in the field of medicinal chemistry. Pyrrolopyrimidines are a major class of fused heterocyclic compounds. Compared with single pyrrole and pyrimidine cores, pyrrolopyrimidines have more diverse and effective pharmacological characteristics as fusion scaffolds.
Silanes are a series of silicon substitutes for carbon alkanes, which consisting of multiple silicon atoms linked to each other as the main chain and hydrogen atoms or other chemical elements linked with the main chain. Silanes are versatile chemicals used in the modification of SPR sensor surfaces. In particular, the silane molecules, such as 3-mercaptopropyl trimethoxy silane, are convenient for use as linkers in surface modification of SPR sensors.
