A bioactive labdane diterpenoid from Curcuma amada and its semisynthetic analogues as antitubercular agents
摘要:
A labdane diterpene dialdehyde was first time isolated from the chloroform extract of rhizomes of Curcuma amada. This compound exhibited antitubercular activity (MIC = 500 mu g/mL) against Mycobacterium tuberculosis H(37)Rv strain in BACTEC-460 assay. Two of its semisynthetic analogues also exhibited antitubercular activity at 250-500 mu g/mL. It is the first report on isolation and antimycobacterial activity of this dialdehyde from C amada.
