Problems solved by technology

However, curcumin is easy to decompose, its structure is unstable, and its inhibitory activity on tyrosinase is not high, which makes the development of curcumin analogues a point of interest for researchers. After years of hard work, researchers have synthesized many The curcumin analogue of base and segment (see formula III)
