Chemical Modifications Of Α-Mangostin For Cytotoxic Study On Lung Cancer Cell Lines, Nan Yadanar Lin Pyae Jan 2019

Chemical Modifications Of Α-Mangostin For Cytotoxic Study On Lung Cancer Cell Lines, Nan Yadanar Lin Pyae

Chulalongkorn University Theses and Dissertations (Chula ETD)

α-Mangostin is a natural oxygenated and prenylated xanthone, which is mainly isolated from the pericarps of Garcinia mangostana. It possesses numerous pharmacological properties and promising therapeutic effects. However, the limitations of α-mangostin such as highly hydrophobicity and poor bioavailability hider its therapeutic applications. To overcome these drawbacks of α-mangostin, chemical modifications have been performed to discover the improved analogs. Herein, two semi-synthetic approaches to obtain new α-mangostin derivatives were investigated by the modifications of the phenolic hydroxy groups at C-3 and C-6 positions involving Smiles rearrangement to install amine functional groups and the addition reaction of isocyanate to form the …
