The present invention provides library of glutarimide-containing polyketide analogs, such as analogs of migrastatin, iso-migrastatin, dorrigocin A and B, epi-dorrigocin, NK30424 A and B and lactimidomycin, methods of synthesizing and using these analogs and further methods of creating a combinatorial library of these compounds through chemical modifications.
Lactimidomycin (LTM, 1) is a macrolide antitumor antibiotic with a glutarimide side chain from Streptomyces amphibiosporus ATCC53964. To further develop LTM and related analogues as drug candidates we have (i) improved LTM production by approximately 20 fold, (ii) identified three new metabolites (2-4) possibly involved in the LTM biosynthetic pathway; (iii) found 3 to be identical with a previously
