Eleven dihydroxy-2-(1-hydroxy-4-methylpent-3-enyl)naphthalene derivatives as anticancer agents through regulating cell autophagy were designed and synthesized. The anticancer activity results indicated that most compounds manifested obvious un-toxic effec

A new method for synthesis of novel hyperbranched poly(ester-amide)s from commercially available AA′ and CBx type monomers has been developed on the basis of a series of model reactions. The hyperbranched poly(ester-amide)s with multihydroxyl end groups are prepared by thermal polycondensation of carboxyl anhydrides (AA′) and multihydroxyl primary amine (CBx) without any catalyst and solvent. The reaction mechanism in the initial stage of polymerization was investigated with in situ 1H NMR. In the initial stage of the reaction, primary amino groups of 2-amino-2-ethyl-1,3-propanediol (AEPO) or tris(hydroxymethyl)aminomethane (THAM) react rapidly with anhydride, forming an intermediate which can be considered as a new ABx type monomer. Further self-polycondensation reactions of the ABx molecules produce hyperbranched polymers. Analysis using 1H and 13C NMR spectroscopy revealed the degree of branching of the resulting polymers ranging from 0.36 to 0.55. These hyperbranched poly(ester-amide)s contain configurational isomers observed by 13C and DEPT 13C NMR spectroscopy, possess high molecular weights with broad distributions and display glass-transition temperatures (Tgs) between 7 and 96°C. The thermogravimetric analytic measurements revealed the decomposition temperature at 10% weight-loss temperatures (Td10%) ranging from 212 to 325°C. Among the hyperbranched poly(ester-amide)s obtained, the polymers with cyclohexyl molecular skeleton structure exhibit the lowest branching degree, the highest glass-transition temperatures, and the best thermal stability.
