Histone acetyltransferase (HAT) p300 and its paralog CBP acetylate histone lysine side chains and play critical roles in regulating gene transcription. The HAT domain of p300/CBP is a potential drug target for cancer. Through compound screening and medicinal chemistry, novel inhibitors of p300/CBP HAT with their IC50 values as low as 620 nM were discovered. The most potent inhibitor is competitive against histone substrates and exhibits a high selectivity for p300/CBP. It inhibited cellular acetylation and had strong activity with EC50 of 1-3 μM against proliferation of several tumor cell lines. Gene expression profiling in estrogen receptor (ER)-positive breast cancer MCF-7 cells showed that inhibitor treatment recapitulated siRNA-mediated p300 knockdown, inhibited ER-mediated gene transcription, and suppressed expression of numerous cancer-related gene signatures. These results demonstrate that the inhibitor is not only a useful probe for biological studies of p300/CBP HAT but also a pharmacological lead for further drug development targeting cancer.

The synthesis and biological evaluation of a series of 12,13-aziridinyl epothilone B analogues is described. These compounds were accessed by a practical, general process that involved a 12,13-olefinic methyl ketone as a starting material obtained by ozonolytic cleavage of epothilone B followed by tungsten-induced deoxygenation of the epoxide moiety. The attachment of the aziridine structural motif was achieved by application of the Ess-Kürti-Falck aziridination, while the heterocyclic side chains were introduced via stereoselective phosphonate-based olefinations. In order to ensure high (E) selectivities for the latter reaction for electron-rich heterocycles, it became necessary to develop and apply an unprecedented modification of the venerable Horner-Wadsworth-Emmons reaction, employing 2-fluoroethoxyphosphonates that may prove to be of general value in organic synthesis. These studies resulted in the discovery of some of the most potent epothilones reported to date. Equipped with functional groups to accommodate modern drug delivery technologies, some of these compounds exhibited picomolar potencies that qualify them as payloads for antibody drug conjugates (ADCs), while a number of them revealed impressive activities against drug resistant human cancer cells, making them desirable for potential medical applications.
