Abstract

Total syntheses of 6 BE-43547A ₂ analogues modified at O35 and C15 sites are reported. Late stage oxidation of 15-deoxy-BE-43547A ₂ delivered 15-epi-BE-43547A ₂ , which verified the proposition that the C15 is an active site for late stage oxidation. The N35 and C15-F of analogues 1b and 1d were synthesized. Cellular level tests indicated O35 is a prohibitive site for modification and substitution of the OH at C15 with F or trim of the OH both led to a dramatic loss of activity. Compound 1e showed comparable inhibitory level towards Panc-1 cells, which indicated that the OH at C15 are permissive site for further modifications.
