The invention discloses a ferrocene burning rate catalyst containing a bis (imidazole or pyrazole-1, 2, 3-triazole) group and a preparation method thereof, the structural formula of the burning rate catalyst is shown in the specification, R1 and R2 independently represent-C or-N, R represents-H or-NO2, and R1 and R2 are different. According to the invention, more nitrogen atoms are introduced into the ferrocene burning rate catalyst, so that hydrogen bonds are easily formed in molecules, and the compounds are not easy to migrate and volatilize under natural conditions and have good thermal stability. As the nitrogen-rich group has high formation heat and combustion heat, the ferrocene burning rate catalyst can improve the energy level of a solid propellant when being used in the solid propellant, and has a good combustion catalysis effect on main components, namely ammonium perchlorate and hexogen, of the solid propellant. Theburning rate catalyst is synthesized by adopting a click reaction method, the preparation method is simple to operate and low in synthesis cost, and the defects of complex synthesis process, high price, high cost and the like of the existing ferrocene and derivatives thereof are overcome.

To identity fast-acting, multistage antimalarial agents, a series of pyridylvinylquinoline-triazole analogues have been synthesized via CuAAC. Most of the compounds display significant inhibitory effect on the drug-resistant malarial Dd2 strain at low submicromolar concentrations. Among the tested analogues, compound 60 is the most potent molecule with an EC50 value of 0.04 ± 0.01 μM. Our current study indicates that compound 60 is a fast-acting antimalarial compound and it demonstrates stage specific action at the trophozoite phase in the P. falciparum asexual life cycle. In addition, compound 60 is active against both early and late stage P. falciparum gametocytes. From a mechanistic perspective, compound 60 shows good activity as an inhibitor of β-hematin formation. Collectively, our findings suggest that fast-acting agent 60 targets dual life stages of the malarial parasites and warrant further investigation of pyridylvinylquinoline hybrids as new antimalarials.
