4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1) belongs to ethers. Esters are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. Cyclic esters are called lactones, regardless of whether they are derived from an organic or inorganic acid. One example of an organic lactone is γ-valerolactone.Formula: C9H12O3

Reactive oxygen species (ROS) are highly overproduced in cancerous tissues, and thus oxidation-responsive nanoparticles (NPs) have emerged as a promising drug carrier for cancer-targeted drug delivery. In this study, we successfully synthesized poly(vanillyl alc.-co-oxalate) (PVAX) polymer with an excellent ROS-responsive capacity. A well-established emulsion-solvent evaporation method was used to fabricate PVAX-based curcumin (CUR)-loaded NPs (PVAX-NPs) and their counterparts (poly(lactic-co-glycolic acid)-based CUR-loaded NPs, PLGA-NPs). It was found that these NPs had a hydrodynamic particle size of approx. 245 nm, narrow size distribution (polydispersity index less than 0.1), neg. zeta potential (around -18 mV), smooth surface appearance, and high drug encapsulation efficiency. Moreover, we found that the CUR release rate of PVAX-NPs was greatly increased in the presence of a hydrogen peroxide-rich environment due to the cleavage of polyoxalate ester bonds in PVAX polymer, resulting in the evenly distribution of CUR within the whole cancer cells. More importantly, PVAX-NPs exhibited much stronger anticancer activities and pro-apoptotic capacities than PLGA-NPs both in vitro and in vivo. These results clearly demonstrate that these ROS-responsive PVAX-NPs can be exploited as a robust anticancer drug delivery platform in chemotherapy. This study involved multiple reactions and reactants, such as 4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1Formula: C9H12O3).
