摘要:
Curcumin, a polyphenol extracted from the rhizome turmeric, has been polymerized to produce a polymer material having a backbone of one or more repeating structural units, at least one of which comprises a curcumin monomer residue. These curcumin-containing polymers have a wide range of pharmacological activities, including, among others antitumor, antioxidant, antiinflammatory, antithrombotic and antibacterial activities. Certain species of these polymers have exhibited remarkable antitumor activity. Water-soluble curcumin derivatives and their use as prodrugs and prodrug carriers are also disclosed.
摘要:
A non-aqueous electrolyte secondary cell provided with: a positive electrode that has a positive electrode active material; a negative electrode; and a non-aqueous electrolyte. The positive electrode active material contains a lithium composite oxide containing Ni, and the non-aqueous electrolyte contains a non-aqueous solvent containing a fluorinated chain carboxylic acid ester and an organochlorine compound. The organochlorine compound is represented by general formula CF3CH2CO—CClR1R2 (where in the formula, R1 and R2 are respectively independent, and are selected from a hydrogen, a halogen, a C1-2 alkyl group, or a C1-2 halogenated alkyl group).
