Abstract
Curcumin, a natural diaryl heptanoid continues to be used as an alternative medicinal agent in many parts of South East Asia for treatment of many ailments. It can be usually obtained from substituted aryl aldehydes and acetylacetone and this route enables synthesis of a diverse set of curcumin analogues. Numerous analogues have been synthesized and tested by several researchers to investigate their activity against known biological targets and to improve upon the pharmacological and ADME profile by modifying substitutions on aromatic rings, β-diketone moiety and two flanking double bonds conjugated to the β-diketone moiety. Successful synthesis of such derivatives with modifications has resulted in the development of potential anticancer candidates that target various stages in cancer cell growth and development. Based on the evidences in modifications of these three functional elements, we have attempted to summarize the structure activity relationship of molecules which can be further utilized by researchers in medicinal chemistry in exploring the structure of curcumin.
Keywords: Curcumin, Anticancer activity of curcumin, SAR, potent derivatives of curcumin.

Drugs and mitochondria
Mitochondria play a central role in the life and death of cells. They are not merely the center for energy metabolism but are also the headquarters for different catabolic and anabolic processes, calcium fluxes, and various signaling pathways. Mitochondria maintain homeostasis in the cell by interacting with reactive oxygen-nitrogen species ...read more
Mitochondria as a Therapeutic Target in Metabolic Disorders
Mitochondria are the primary site of adenosine triphosphate (ATP) production in mammalian cells. Moreover, these organelles are an important source of reactive oxygen and nitrogen species in virtually any nucleated cell type.
