A copper-catalyzed radical cross-coupling of cyclobutanone oxime esters with sulfonyl hydrazides was developed. The copper-based catalytic system proved crucial for cleavage of the C-C bond of cyclobutanone oximes and for selective C-S bond-formation involving persistent sulfonyl-metal radical intermediates. This protocol was distinguished by the low-cost catalytic system, which does not require ligand, base, or toxic cyanide salt, and by the use of readily accessible starting materials, as well as broad substrate scope, providing an efficient approach to various diversely substituted cyano-containing sulfones.

Phosphoinositide 3-kinases (PI3Ks) mediate a series of events related to cell growth, proliferation, survival, and differentiation. Overexpression of PI3Ks can lead to the dysregulation of cell homeostasis and cause tumorigenesis. In this study, rationally designed compounds were investigated as PI3Kα-selective inhibitors. Our efforts culminated in the discovery of a series of quinazolin-4(3H)-one derivatives with 2-substituted-N-methylpropanamide substitutions as PI3Kα-selective inhibitors. The best compound, I, has PI3Kα enzymic and cellular IC₅₀ values of 1.8 and 12.1 nM, resp. It exhibits biochem. selectivities for PI3Kα over PI3Kβ/δ/γ of 150/7.72/7.67-fold and cellular selectivities of 115/15.1/>826-fold, resp. Compound I is 59% orally bioavailable with a dose-normalized AUC of 3090 nM. These effects translated into in vivo conditions, as I significantly time- and dose-dependently inhibited phosphorylation of Akt in BT-474 s.c. xenograft mice and inhibited tumor growth.

Novel insecticidal targets are always in demand due to the development of resistance. OfHex1, a β-N-acetyl-D-hexosaminidase identified in Ostrinia furnacalis (Asian corn borer), is involved in insect chitin catabolism and has proven an ideal target for insecticide development. In this study, structure-based virtual screening, structure simplification, and biol. evaluation are used to show that compounds with a biphenyl-sulfonamide skeleton have great potential as OfHex1 inhibitors. Specifically, compounds 10k, 10u, and 10v have K_i values of 4.30, 3.72, and 4.56μM, resp., and thus, they are more potent than some reported nonglycosyl-based inhibitors such as phlegmacin B₁ (K_i = 26μM), berberine (K_i = 12μM), compound 2 (K_i = 11.2μM), and compound 3 (K_i = 28.9μM). Furthermore, inhibitory kinetic assessments reveal that the target compounds are competitive inhibitors with respect substrate, and based on toxicity predictions, most of them have potent insecticidal properties. The obtained results indicate that the biphenyl-sulfonamide skeleton characterized by simple chem. structure, synthetic tractability, potent activity, and low toxicity has potential for further development in pest management targeting OfHex1.

Brulet, Jeffrey W.;Borne, Adam L.;Yuan, Kun;Libby, Adam H.;Hsu, Ku-Lung research published 《 Liganding Functional Tyrosine Sites on Proteins Using Sulfur-Triazole Exchange Chemistry》, the research content is summarized as follows. Tuning reactivity of sulfur electrophiles is key for advancing click chem. and chem. probe discovery. To date, activation of the sulfur electrophile for protein modification has been ascribed principally to stabilization of a fluoride leaving group (LG) in covalent reactions of sulfonyl fluorides and arylfluorosulfates. We recently introduced sulfur-triazole exchange (SuTEx) chem. to demonstrate the triazole as an effective LG for activating nucleophilic substitution reactions on tyrosine sites of proteins. Here, we probed tunability of SuTEx for fragment-based ligand discovery by modifying the adduct group (AG) and LG with functional groups of differing electron-donating and -withdrawing properties. We discovered the sulfur electrophile is highly sensitive to the position of modification (AG vs. LG), which enabled both coarse and fine adjustments in solution and proteome activity. We applied these reactivity principles to identify a large fraction of tyrosine sites (~30%) on proteins (~44%) that can be liganded across >1500 probe-modified sites quantified by chem. proteomics. Our proteomic studies identified noncatalytic tyrosine and phosphotyrosine sites that can be liganded by SuTEx fragments with site specificity in lysates and live cells to disrupt protein function. Collectively, we describe SuTEx as a versatile covalent chem. with broad applications for chem. proteomics and protein ligand discovery.
