Novel benzo[d] thiazole-based analogues were synthesized with the aim of screening their in vitro anticancer activity. All the new derivatives 4-21 were evaluated against human hepatocellular carcinoma (HepG-2) and breast cancer cells (MCF-7) using doxorubicin as a reference drug. All compounds exhibited excellent potency against MCF-7 (IC50 values ranging from 0.71 +/- 0.4 to 1.04 +/- 0.7 mu M) and variable promising potency against HepG-2 (IC50 ranged from 2.53 +/- 2.5 to 3.47 +/- 3.4 mu M) comparing with the standard (IC50 = 1.03 +/- 0.8 mu M and 2.85 +/- 1.9 mu M, respectively) in addition to their safety towards the normal cell line. Compounds 5, 6, 7, 13 and 16 having the highest cytotoxic activity, were further evaluated for their EGFR inhibitory activity using Erlotinib as a reference drug. Molecular docking studies were performed for the promising compounds 5, 6 and 7 to interpret their detected enzymatic activities based upon their binding interactions with the receptor. Moreover, cell cycle analysis and detection of apoptosis induction illustrated that compounds 5 and 6 exhibited a significant pre G(1) and G(2)/M cell cycle arrest, in comparison with the untreated MCF-7 cells. In addition, compounds 5 and 6 elevated the levels of the oncogenic parameters; Bax, p53 and caspase-3 with decreased level of Bcl-2. These previous encouraging results of biological evaluation of the newly synthesized benzothiazoles could recommend an excellent framework toward the detection of new potent antitumor leads.

The extensively developed ene-type enantioselective cycloisomerization of classical 1,n-enynes provides an efficient approach to chiral cyclic 1,4-dienes. In contrast, the catalytic asymmetric heteroarenyne (heteroarene-alkyne) cycloisomerization involving the dearomative transformation of endocyclic aromatic C=C bonds remains unknown. Herein, we communicate a PdH-catalyzed enantioselective heteroarenyne cycloisomerization reaction of alkyne-tethered indole substrates (formal 1,5- and 1,6-enynes). Based on this strategy, a variety of structurally diverse chiral spiro and fused indoline derivatives bearing quaternary stereocenters and exocyclic C=C bonds are afforded in moderate to excellent yields and excellent enantioselectivities (up to 98 % ee). The classical ene-type enantioselective 1,5-enyne cycloisomerization of N-vinylpropiolamides is also developed to afford chiral 2-pyrrolones in good to excellent ee values.

We describe the preparation of two monomers that bear complementary nucleobases at the edges (guanine-2′-deoxycytidine and 2-aminoadenine-2′-deoxyuridine) and that are conveniently protected and activated for solid-phase automated DNA synthesis. We report the optimized synthetic routes leading to the four nucleobase derivatives involved, their cross-coupling reactions into dinucleobase-containing monomers, and their oligomerization in the DNA synthesizer.

Selective modification of the hydroxyl groups of sugars has been a long-standing challenge due to their proximate relative reactivity. Herein, we report a TMSOTf-catalyzed selective acetylation of the non-anomeric hydroxyl groups of several per-O-TMS-protected sugar substrates while leaving their anomeric group unaffected. In addition to standing versatile by itself, the anomeric O-TMS group left intact can be functionalized to afford key sugar precursors such as imidate donors, which could otherwise be synthesized via a stepwise anomeric deprotection-functionalization procedure.

The photoredox chloroacylation of alkenes has been developed as a substitute for the Friedel-Crafts acylation of alkenes to beta-chloroketones. The direct generation of acyl radical species from acid chlorides under the photoredox conditions allows the formation of beta-chloroketones without dehydrochlorination with the help of KHCO3. The synthetic utility of the current method is demonstrated in the one-pot synthesis of dihydroisoxazole, dihydropyrazole, and dihydropyrimidine-2-thione in 1 mmol scale.

Trace volatile organic compounds (VOCs) such as aldehydes and aromatics significantly deteriorate the indoor air quality especially in newly-decorated buildings. The universal water vapor would greatly decrease the adsorption capacity of ad-sorbents for trace VOCs via competitive adsorption and capillary condensation. Herein, we developed a strategy to subsequently modify the internal and external surface of CAU-1, an aluminum-based metal-organic framework (MOF), to significantly improve its humidity resistance. First, anhydrides were used to transfer amino groups of CAU-1 into hydrophobic groups via amide reaction. Second, polydimethylsiloxane was used to form a hydorphobic coating on its external surface. The adsorption capacity of as-modified CAU-1 for 1 ppm toluene increased about 6 times under 50% relative humidity (RH) at 298 K, even much higher than those of common adsorbents including hydrophobic ZSM-5. In addition, it could be completely regenerated below 373 K, about 65 K lower than that required for regenerating ZSM-5 under the same condition, which not only greatly reduces the energy consumption but also improves the safety and feasibility of in-situ regeneration of adsorbents in indoor environment.

A mechanistically unique functionalization strategy for a benzylic C(sp(3))-H bond has been developed based on the facile oxidation event of indole substrates. This novel pathway was initiated by efficient radical generation at the benzylic position of the substrate, with subsequent transition metal catalysis to complete the overall transformation. Ultimately, an aryl or an acyl group could be effectively delivered from an aryl (pseudo)halide or an acid anhydride coupling partner, respectively. The developed method utilizes mild conditions and exhibits a wide substrate scope for both substituted indoles and C(sp(2))-based reaction counterparts. Mechanistic studies have shown that competitive hydrogen atom transfer (HAT) processes, which are frequently encountered in conventional methods, are not involved in the product formation process of the developed strategy.

The first total synthesis of three echinodermatous sialyl inositol phosphosphingolipids, which exhibit unusual neuritogenic activity in the absence of nerve growth factor, are reported. Highlights of the syntheses include 9-O-methylation on sialic acid, inter-residual amide bond formation between sialic acid residues, and highly stereo- and regioselective sialylation of inositol. A key phosphodiester linkage between the mono-, di-, and trisialyl inositols and ceramide was formed at a late state employing the phosphoramidite method.

To develop antitumor drugs capable of targeting energy metabolism in the tumor microenvironment, we produced a series of potent new biguanide derivatives via structural modification of the arylbiguanide scaffold. We then conducted biological screening using hypoxia inducible factor (HIF)-1- and unfolded protein response (UPR)-dependent reporter assays and selective cytotoxicity assay under low glucose conditions. Homologation studies of aryl-(CH2)(n)-biguanides (n=0-6) yielded highly potent derivatives with an appropriate alkylene linker length (n=5, 6). The o-chlorophenyl derivative 7l (n=5) indicated the most potent inhibitory effects on HIF-1- and UPR-mediated transcriptional activation (IC50; 1.0 +/- 0.1 mu M, 7.5 +/- 0.1 mu M, respectively) and exhibited selective cytotoxicity toward HT29 cells under low glucose condition (IC50; 1.9 +/- 0.1 mu M). Additionally, the protein expression of HIF-1 alpha induced by hypoxia and of GRP78 and GRP94 induced by glucose starvation was markedly suppressed by the biguanides, thereby inhibiting angiogenesis. Metabolic flux and fluorescence-activated cell sorting analyses of tumor cells revealed that the biguanides strongly inhibited oxidative phosphorylation and activated compensative glycolysis in the presence of glucose, whereas both were strongly suppressed in the absence of glucose, resulting in cellular energy depletion and apoptosis. These findings suggest that the pleiotropic effects of these biguanides may contribute to more selective and effective killing of cancer cells due to the suppression of various stress adaptation systems in the tumor microenvironment.
