- Discovery of acylsulfonohydrazide-derived inhibitors of the lysine acetyltransferase, kat6a, as potent senescence-inducing anti-cancer agents
-
A high-throughput screen designed to discover new inhibitors of histone acetyltransferase KAT6A uncovered CTX-0124143 (1), a unique aryl acylsulfonohydrazide with an IC50 of 1.0 μM. Using this acylsulfonohydrazide as a template, we herein disclose the results of our extensive structure-activity relationship investigations, which resulted in the discovery of advanced compounds such as 55 and 80. These two compounds represent significant improvements on our recently reported prototypical lead WM-8014 (3) as they are not only equivalently potent as inhibitors of KAT6A but are less lipophilic and significantly more stable to microsomal degradation. Furthermore, during this process, we discovered a distinct structural subclass that contains key 2-fluorobenzenesulfonyl and phenylpyridine motifs, culminating in the discovery of WM-1119 (4). This compound is a highly potent KAT6A inhibitor (IC50 = 6.3 nM; KD = 0.002 μM), competes with Ac-CoA by binding to the Ac-CoA binding site, and has an oral bioavailability of 56% in rats.

- ARYL SULFONOHYDRAZIDES
-
Compound of formula (I) wherein A is selected from (i), where RF1 is H or F; (ii); (iii) a N-containing C6 heteroaryl group; and B is (B), where X1 is either CRF2 or N, where RF2 is H or F; X2 is either CR3 or N, where R3 is selected from H, Me, CI, F OMe; X3 is either CH or N; X4 is either CRF3 or N, where RF3 is H or F; where only one or two of X1, X2, X3 and X4 may be N; and R4 is selected from I, optionally substituted phenyl, optionally substituted C5-6 heteroaryl; optionally substituted C1-6 aIkyI and optionally substituted C1-6 alkoxy, which are useful in the treatment of a condition ameliorated by the inhibition of MOZ.

- A convenient synthesis of heteroaryl benzoic acids via Suzuki reaction
-
An one step approach to heteroaryl benzoic acids from readily accessible heteroaryl halides and carboxybenzene boronic acids is described. The Suzuki coupling is carried out in the presence of Pd(PPh3)4 and sodium carbonate in aqueous acetonitrile. The scope and limitations of the reaction are discussed.
