The present invention is directed to hemi phorboxazole A: and its stereoisomers, as well as derivatives of hemi phorboxazole A of formula I: wherein ring A is aryl or a 5- or 6-membered heteroaryl optionally substituted with one or more of halogen, -OH, or -C1-6alkyl; and R is-CN, a 5- or 6-membered heteroaryl, or halogen; and the pharmaceutically acceptable salt forms thereof, in addition to methods of using these compounds.

A synthesis providing totally synthetic (+)-hemi-phorboxazole A (1), proceeding in two steps (85% yield) from known vinyl iodide precursor (+)-2, has been achieved in conjunction with the design, synthesis, and biological evaluation of two hemi-phorboxazole analogues [(+)-3 and (-)-4] featuring ring replacements inscribed within the macrolide. Although hemi-phorboxazole A (1) displayed no activity when tested against Candida albicans and two human cancer cell lines, analogue (-)-4 exhibited significant tumor cell growth inhibitory activity in the nanomolar range against HCT-116 (colon) and SK-BR-3 (breast), while (+)-3 displayed promising antifungal activity against C. albicans.
