| Research Abstract |
This project pursued unified total synthesis and structure-activity relationships of marine macrolide natural products of cyanobateria origin. Our concise synthesis of neopeltolide, a highly potent antiproliferative macrolide, enabled us to elucidate its pharmacophoric structural elements required for potent activity. Several truncated neopeltolide analogues with nanomolar activity were successfully designed on the basis of our pharmacophore model. Concise total synthesis of lyngbyaloside B, a moderately cytotoxic macrolide glycoside, and its 13-demethyl analogue was also achieved. Design, synthesis, and biological evaluation of chimeric macrolides were undertaken to show that polyketide macrolides offer unique structural motifs useful for the development of novel antiproliferative agents.
