Fluorescent bioorthogonal smart probes across the visible spectrum will enable sensitive visualization of metabolically labeled molecules in biological systems. Here we present a unified design, based on the principle of photoinduced electron transfer, to access a panel of highly fluorogenic azide probes that are activated by conversion to the corresponding triazoles via click chemistry. Termed the CalFluors, these probes possess emission maxima that range from green to far red wavelengths, and enable sensitive biomolecule detection under no-wash conditions. We used the CalFluor probes to image various alkyne-labeled biomolecules (glycans, DNA, RNA, and proteins) in cells, developing zebrafish, and mouse brain tissue slices.

A series of simplified ring-opened resorcylic acid lactone (RAL) derivatives were conveniently synthesized to target FLT3 and its mutants either irreversibly or reversibly. Our design of covalent FLT3 inhibitors is based on cis-enone RALs (e.g., L-783,277) that have a beta-resorcylic acid as the core structure. The designed compounds contain three types of Michael acceptors (acrylamide, vinylsulfonamide and maleimide) as potential covalent traps of a cysteine residue at the binding site of kinases. A variety of functional substitutions were also introduced to maximize the binding interactions. Biological evaluations revealed that compound 17, despite the presence of a highly reactive maleimide Michael acceptor, is a potent covalent FLT3 inhibitor which shows some specificity in cellular assays. On the other hand, compounds 2 and 6 containing acrylamide or vinylsulfonamide groups are reversible towards FLT3 binding, and are potent and selective inhibitors of mutant FLT3-ITD versus wt-FLT3. They also inhibit cell proliferation in FLT3-ITD expressing cell line MV-4-11 as compared to wt-FLT3 expressing cell line THP-1 and non-FLT3 cell lines (K562, HL60 and Hek-293T).

Heat shock protein 90 is an emerging target for oncology therapeutics. Inhibitors of this molecular chaperone, which is responsible for the maintenance of a number of oncogenic proteins, have shown promise in clinical trials and represent a new and exciting area in the treatment of cancer. Heat shock protein 90 inhibitors have huge structural diversity, and here we present the lead identification of novel inhibitors based on beta-lactam and imine templates. beta-Lactam 5 and imines 12 and 18 exhibit binding to heat shock protein 90-alpha with IC50 values of 5.6 muM, 14.5 muM, and 22.1 muM, respectively. The binding affinity displayed by these compounds positions them as lead compounds for the design of future inhibitors of heat shock protein 90 based on the beta-lactam and imine templates.

A series of peptide mimetic aldehyde inhibitors of calpain I was prepared in which the P2 and P3 amino acids were replaced by substituted 3,4-dihydro-1,2-benzothiazine-3-carboxylate 1,1-dioxides. The effect of 2, 6, and 7-benzothiazine substituents and the P1 amino acid was examined. Potency of these inhibitors, 15c-p, against human recombinant calpain I is particularly dependent upon the 2-substituent, with methyl and ethyl generally more potent than hydrogen, isopropyl, isobutyl, or benzyl. The more potent diastereomer of 15m possesses the (S) absolute configuration at the 3-position of the 3,4-dihydro-l,2-benzothiazine. Potency of the best inhibitors in this series (IC50=5-7 nM) compares favorably with that of conventional N-benzyloxycarbonyl dipeptide aldehyde inhibitors bearing L-Leu or L-Val residues at P2. The achiral unsaturated 1,2-benzothiazine analogues 26a-d are also potent calpain I inhibitors, while 3,4-dihydro-2,1-benzoxathiin (15a,b), 1,2,4-benzothiadiazine (32a,b), and tetrahydroisoquinolinone (36a,b) analogues are less potent.

Many natural products that show therapeutic activities are often difficult to synthesize or isolate and have unknown targets, hindering their development as drugs. Identifying druggable hotspots targeted by covalently acting anti-cancer natural products can enable pharmacological interrogation of these sites with more synthetically tractable compounds. Here, we used chemoproteomic platforms to discover that the anti-cancer natural product withaferin A targets C377 on the regulatory subunit PPP2R1A of the tumor-suppressor protein phosphatase 2A (PP2A) complex leading to activation of PP2A activity, inactivation of AKT, and impaired breast cancer cell proliferation. We developed a more synthetically tractable cysteine-reactive covalent ligand, JNS 1-40, that selectively targets C377 of PPP2R1A to impair breast cancer signaling, proliferation, and in vivo tumor growth. Our study highlights the utility of using chemoproteomics to map druggable hotspots targeted by complex natural products and subsequently interrogating these sites with more synthetically tractable covalent ligands for cancer therapy. Many natural products exhibit therapeutic activity, but translating these molecules into drugs is hindered by difficulty in their synthesis and isolation. Grossman, Ward et al. show that chemoproteomic technologies can be used to discover simpler molecules that react with the same sites as those targeted by natural products.

An auxiliary-enabled Pd-catalyzed highly regio- and stereoselective sp3 C-H activation and the direct arylation of the C3-position of oxygen heterocycles, such as tetrahydrofuran and 1,4-benzodioxane systems, are reported. An efficient stereoselective construction of cis 2,3-disubstituted tetrahydrofuran derivatives (analogues of norlignans) and cis 2,3-disubstituted 1,4-benzodioxane derivatives (analogues of neolignans) is described. The direct C(sp3)-H arylation of the C3-position of (R)- or (S)- tetrahydrofuran-2-carboxamides furnished the corresponding (2R,3R) and (2S,3S) C3-arylated THF scaffolds as major compounds with very high regio- and diastereoselectivities. The stereochemistry of the products obtained in this work were unambiguously assigned on the basis of the X-ray structure analyses of representative compounds 3b, 3e, 4p, and 7.
