Abstract: Derivatives of plumbagin can be selectively cytotoxic to breast cancer cells. Derivative ‘A’ (Acetyl Plumbagin) has emerged as a lead molecule for testing against estrogen positive breast cancer and has shown low hepatotoxicity as well as overall lower toxicity in nude mice model. The toxicity of derivative ‘A’ was determined to be even lower than vehicle control (ALT and AST markers). The possible mechanism of action identified based on the microarray experiments and pathway mapping shows that derivative ‘A’ could be acting by altering the cholesterol-related mechanisms. The low toxicity profile of derivative ‘A’ highlights its possible role'as future anti-cancer drug and/or as an adjuvant drug to reduce the toxicity of highly toxic chemotherapeutic'drugs.

Abstract: Disclosed are a substrate with a microstructure and a method for producing the same. In this method microparticles of a random allocation by means of a natural self-assembly mechanism are used to coat on a master mold. Firstly, hollow micro glass particles within a specific size range are mixed with a UV-curable adhesive to become a mixed solution. Afterwards, the master mold is dip-coated in the mixed solution and the microparticles coated on the master mold are self-assembled. To fix the microparticles on the master mold to form a sphere array microstructure with a three dimensional random allocation, a UV light source is used to radiate the master mold for curing. Afterwards, an inverse mold with the corresponding microstructure is fabricated by electroforming or polydimethylsiloxane (PDMS) casting the master mold. Thus, the inverse mold can be applied to the fabrication of a substrate with the corresponding microstructure.
