Abstract:

Pyrazoles have been studied for over a century as an important class of heterocyclic compounds and continue to attract considerable interest due to the broad range of biological activities they possess. The incorporation of the essential structural features of pyrazoles with a ferrocene moiety could provide new derivatives with unexpected and/or enhanced biological activities since several ferrocene derivatives have already been shown to be active against a number of tumors. For this reason, we investigated the synthesis of ferrocenyl-substituted pyrazoles, such as 1-alkyl/aryl-5-ferrocenylpyr

Pyrazoles have been studied for over a century as an important class of heterocyclic compounds and continue to attract considerable interest due to the broad range of biological activities they possess. The electrophilic cyclization of the acetylenic hydrazones initiated by molecular iodine could provide new ways of synthesizing biologically active 4-iodopyrazole derivatives, which are important precursors for the synthesis of highly substituted pyrazole derivatives. For this reason, we investigated the synthesis of 4-iodopyrazole derivatives, such as 1-aryl- 5-alkyl/aryl-4-iodopyrazoles, star

It is caused by either the degeneration of osteoblasts leading to weaker bone forming activity or the promotion of osteoclasts increasing bone resorption activity. To treat osteoporosis, several drugs are available now. However, there are still some drawbacks of the drugs such as many side effects and high cost. According to the situation, we would like to research and synthesize new compounds to treat osteoporosis.

The new polymer are studied on their structure,physical and photoelectronic properties. 　The polymers dissolved readily in common organic solvents and had high glass-transition temperature values of 149°C ~ 167 °C for P3 ~P6.They were stable up to approximately 260°C ~ 350°C in N2 and the anaerobic char yield was around 28 ~ 35% at 800 °C except
