We report iridium-catalyzed C-C formation between benzamides and terminal alkynes. With the choice of a suitable ligand, a C-H alkynylation or alkenylation product could be obtained selectively. The directed C-H alkynylation proceeded without the need for an external oxidant, while the directed C-H alkenylation likely involves an unusual vinylidene mechanism. This divergent reactivity provides access to both alkynylation and alkenylation products from the same set of starting materials.

A series of 2,7-disubstituted-thieno[3,2-d]pyrimidine derivatives were designed, synthesized and evaluated as novel focal adhesion kinase (FAK) inhibitors. The novel 2,7-disubstituted-thieno[3,2-d]pyrimidine scaffold has been designed as a new kinase inhibitor platform that mimics the bioactive conformation of the well-known diaminopyrimidine motif. Most of the compounds potently suppressed the enzymatic activities of FAK and potently inhibited the proliferation of U-87MG, A-549 and MDA-MB-231 cancer cell lines. Among these derivatives, the optimized compound 26f potently inhibited the enzyme (IC50 = 28.2 nM) and displayed stronger potency than TAE-226 in U-87MG, A-549 and MDA-MB-231 cells, with IC50 values of 0.16, 0.27, and 0.19 μM, respectively. Compound 26f also exhibited relatively less cytotoxicity (IC50 = 3.32 μM) toward a normal human cell line, HK2. According to the flow cytometry results, compound 26f induced the apoptosis of MDA-MB-231 cells in a dose-dependent manner and effectively arrested MDA-MB-231 cells in G0/G1 phase. Further investigations revealed that compound 26f potently suppressed the migration of MDA-MB-231 cells. Collectively, these data support the further development of compound 26f as a lead compound for FAK-targeted anticancer drug discovery.

Conversion of a wide range of N-Boc amides to aryl ketones was achieved with Grignard reagents via chemoselective C(O)-N bond cleavage. The reactions proceeded under catalyst-free conditions with different aryl, alkyl, and alkynyl Grignard reagents. α-Ketoamide was successfully converted to aryl diketones, while α,β-unsaturated amide underwent 1,4-addition followed by C(O)-N bond cleavage to provide diaryl propiophenones. N-Boc amides displayed higher reactivity than Weinreb amides with Grignard reagents. A broad substrate scope, excellent yields, and quick conversion are important features of this methodology.

The L-type amino acid transporter 1 (LAT1, SLC7A5) transports essential amino acids across the blood-brain barrier (BBB) and into cancer cells. To utilize LAT1 for drug delivery, potent amino acid promoieties are desired, as prodrugs must compete with millimolar concentrations of endogenous amino acids. To better understand ligand-transporter interactions that could improve potency, we developed structural LAT1 models to guide the design of substituted analogues of phenylalanine and histidine. Furthermore, we evaluated the structure-activity relationship (SAR) for both enantiomers of naturally occurring LAT1 substrates. Analogues were tested in cis-inhibition and trans-stimulation cell assays to determine potency and uptake rate. Surprisingly, LAT1 can transport amino acid-like substrates with wide-ranging polarities including those containing ionizable substituents. Additionally, the rate of LAT1 transport was generally nonstereoselective even though enantiomers likely exhibit different binding modes. Our findings have broad implications to the development of new treatments for brain disorders and cancer.
