Abstract: Breast cancer (BC) is the most prevalent type of in world and main reason women die from cancer. Due to significant side effects conventional treatments such as chemotherapy radiotherapy, search for supplemental alternative natural drugs with lower toxicity interest researchers. Curcumin (CUR) a polyphenol extracted turmeric. Numerous studies have demonstrated that CUR an effective anticancer drug works by modifying different intracellular signaling pathways. CUR's therapeutic utility severely constrained its short half-life vivo, low water solubility, poor stability, quick metabolism, oral bioavailability, potential gastrointestinal discomfort high doses. One practical solutions aforementioned issues development targeted delivery systems (TDDSs) based on nanomaterials. To improve targeting efficacy serve reference use TDDSs clinical setting, this review describes physicochemical properties bioavailability mechanism action BC, emphasis recent BC combination CUR, including passive TDDSs, active TDDSs.

Abstract Micellar photocatalysis has been used to overcome oxygen quenching and enable a [2+2] photocycloaddition through triplet‐energy transfer in water under aerobic conditions. The cheap commercially available self‐assembling sodium dodecyl sulfate (SDS) micelles were found increase the tolerance of typically oxygen‐sensitive reaction. Furthermore, use micellar solution was activate α,β‐unsaturated carbonyl compounds energy allow photocycloadditions take place.
