This work involves the synthesis of different five, six and seven membered heterocyclic rings starting from different chalcone derivatives. This work is divided into five different parts:
Background:
Hormone therapy is the first targeted therapy also called estrogen suppression therapy often used as an adjuvant therapy to reduce the risk of cancer back after surgery or cancer that has spread. Tamoxifen is used to treat early breast cancer in women who have already been treated with surgery, radiation, and/or chemotherapy. It is used to reduce the risk of developing a more serious type of breast cancer in women.
Magnesium is a reactive element, poor corrosion resistance and highly unstable, which have limited its industrial applications.One of the most effective ways to improve the corrosion resistance of Mg and its alloys is to form a coating on the surface to isolate them from the environment.This can be achieved by forming or applying some type of functional barrier layer. There are several surface coating treatment techniques,including electrochemical plating (electroplating), conversion coating,anodizing, hybrid coatings, and vapor-phase process.
