Problems solved by technology

[0009] The literature reports on p-tert-butyl monooxabicalix[4]arenes are very limited, mainly due to the low synthesis yield of the parent material and fewer types of derivatization reactions. In addition, p-tert-butyl monooxabicalix[4]arene [4] Arene derivatives reported in the literature are mainly used for molecular ion recognition, and their pharmaceutical applications have not yet been carried out. Therefore, this study designed and synthesized amide-substituted p-tert-butyl monooxabihocalix[4]arene derivatives that have not been reported in the literature. to obtain oxacalixarene derivatives with novel structure and excellent water solubility; and select common tumor cells to conduct MTT or SRB experiments on the synthesized compounds to study whether the synthesized compounds have cytotoxicity and the strength of the effect on human cancer cells , from which compounds with anti-tumor activity and strong activity were screened

Description

technical field [0001] The invention belongs to the field of medicinal chemistry, and in particular relates to a class of p-tert-butyl monooxabicalix[4]arene compounds with novel structures and the application of the compounds in medicine. Background technique [0002] Calixarene is a kind of cyclic oligomer obtained by condensation reaction of phenolic substances with aldehydes or ketones. It is named calixarene because its molecular shape resembles the Greek Holy Grail. Its history can be traced back to 1872 when German chemist A. Baeyer (ChemLife, 2002, 22 (3): 265-267) studied the heating reaction of phenol and formaldehyde aqueous solution. Because the synthesis method has many steps and low yield, so Failed to get people's attention. In the late 1970s, C.D.Gutsche (J.Am.Chem.Soc., 1981,103(13):3782-3792) successfully established a high-yield one-step synthesis of calix[n]arenes by strictly controlling the reaction conditions In this way, the rapid development of cali...
