Aiming at generating a series of monoterpene indolealkaloids with enhanced multidrug resistance (MDR) reversing activity in cancer, two major epimeric alkaloids isolated from Tabernaemontana elegans, tabernaemontanine (1) and dregamine (2), were derivatized by alkylation of the indole nitrogen. Twenty-six new derivatives (3-28) were prepared by reaction with different aliphatic and aromatic halides
