The present invention provides compounds according to Formula (I): or pharmaceutically acceptable salts, solvates, esters, prodrugs, tautomers, and isomers thereof, wherein: ring A, n, q, R1, R2, R3, R4, R5, R6, each R7, each R7A, and R8 are each selected independently of each other and as defined herein. The invention also provides pharmaceutical compositions comprising such compounds (optionally in combination with one or more additional active ingredients), and methods for their use in treating or preventing a wide range of cancers.
essential for activity. An aryl group is a good replacement for the olefin. The totalsynthesis of structurally simplified C11-deoxypsymberin (29) was completed, and its activity is consistently more potent than the natural product which provides a unique opportunity for further SAR studies in the psymberin and pederin family. Preliminary mechanism studies suggest the mode of action of psymberin is
showcased in the preparation of advanced psymberin analogues. The biological data of these analogues are presented. 1 Introduction 2 Methodology Development 3 TotalSynthesis of Psymberin 4 Synthesis of Psymberin Analogues: The Discovery of C11-Deoxypsymberin 5 Conclusion (diacetoxyiodo)benzene - psymberin - oxidative cyclization - totalsynthesis - antitumor
