Reported is an iridium catalyst for ortho-selective C-H borylation of challenging secondary aromatic amide substrates, and the regioselectivity is controlled by hydrogen-bond interactions. The BAIPy-Ir catalyst forms three hydrogen bonds with the substrate during the crucial activation step, and allows ortho-C-H borylation with high selectivity. The catalyst displays unprecedented ortho selectivities for a wide variety of substrates that differ in electronic and steric properties, and the catalyst tolerates various functional groups. The regioselective C-H borylation catalyst is readily accessible and converts substrates on gram scale with high selectivity and conversion.

The 5-monophosphate group plays an important role in strand selection during gene silencing mediated by small-interfering RNA. We show that blocking of 5 phosphorylation of the sense strand by introducing a 5-morpholino modification improves antisense strand selection and RNAi activity. The 5-morpholino modification of the antisense strand triggers complete loss of activity.

In this study, we introduced 1, 2, 4-triazole groups into panaxadiol (PD) to obtain 18 panaxadiol triazole derivatives. Five cancer cells and one normal cell were evaluated for cytotoxicity by MTT assay. The results showed that most of the derivatives could inhibit cancer cell proliferation, and the anti-proliferative activity of compound A1 was the most significant. For HepG-2 cells, the IC50 value was 4.21 +/- 0.54 mu M, which was nearly 15 times higher than the activity of PD. Further studies showed that compound A1 could induce apoptosis in HepG-2 cells, and could enhance the expression of Cl-caspase-3, Cl-caspase-9 and Cl-PARP. Moreover, Western blot analysis showed that after treating HepG-2 cells with compound A1, the expression of p53 protein was increased and the ratio of Bax/Bcl-2 was gradually increased. The cytoplasmic Bax is then translocated to the mitochondria, causing the release of Cyt c protein. Therefore, the results indicate that compound A1 induces apoptosis through the mitochondrial pathway and can be used the potential to develop new anti-proliferative agents.

This work analyzed the chemical compositions and evaluated the antioxidant and cytotoxic activities of essential oils (EO) of Eugenia patrisii (Epat), Eugenia stipitata (Esti), Myrcia splendens (Mspl), Myrcia sylvatica (Msyl), Psidium guajava (Pgua), and Psidium guineense (Pgui-1 and Pgui-2) from the Brazilian Amazon. Sesquiterpenoids were found in high concentrations in the oils of E. patrisii and M. splendens, which were rich in E-caryophyllene (32.0% and 45.8%); E. stipitata and M. sylvatica, which displayed germacrene D (11.8%) and germacrene B (24.5%); and P. guajava that showed epi-beta-bisabolol (16.1%) as the main compound. However, P. guineense samples (Pgui-1 and Pgui-2) were rich in monoterpenoids such as limonene (Pgui-1: 30.2%; Pgui-2 30.4%) and alpha-pinene (Pgui-1: 22.5%; Pgui-2: 17.7%). The samples showed a weak and moderate antioxidant activities in the DPPH assay, displaying inhibition rates from 11.5% to 38.6% (at 10 mg/mL). All samples were cytotoxic against human cancer cells by the MTT method. Epat oil showed higher activity against melanoma (SKMEL-19, IC(50)5.8 mu g/mL), gastric (AGP01, IC(50)3.2 mu g/mL), and colon (HCT116, IC(50)6.7 mu g/mL). Meanwhile, the samples Pgua and Pgui were more active against breast cancer cells (MCF7, IC(50)12.4 mu g/mL and 11.6 mu g/mL, respectively).

Multitarget synthetic strategies to access novel photochromic 3H-naphtho[2,1-b]pyrans decorated with pyridyl units are described. The new pyridyl-substituted 3H-naphtho[2,1-b]pyrans display good photochromic properties with reversible generation of photomerocyanines, which exhibit mainly orange/red hues. Photochromic parameters including photocolorability and persistence of color vary tremendously on structural modification of the naphthopyran core.

Transition metal-catalyzed cross-couplings have been widely employed in the synthesis of many important molecules in synthetic chemistry for the construction of diverse C-C bonds. Conventional cross-coupling reactions require active electrophilic coupling partners, such as organohalides or sulfonates, which are not environmentally friendly enough. Herein, we disclose the first nickel-catalyzed Suzuki-Miyaura cross-coupling of aryl anhydrides and arylboronic acids for the synthesis of biaryls in a decarbonylation manner. The reaction tolerates a wide range of electron-withdrawing, electron-neutral, and electron-donating substituents in this process.

Oxidative stress is implicated in the pathogenesis of a wide variety of neurodegenerative disorders, and accordingly, dietary supplement of exogenous antioxidants or/and upregulation of the endogenous antioxidant defense system are promising for therapeutic intervention or chemoprevention of neurodegenerative diseases. Nrf2, a master regulator of the cellular antioxidant machinery, cardinally participates in the transcription of cytoprotective genes against oxidative/electrophilic stresses. Herein, we report the synthesis of 59 structurally diverse dithiolethiones and evaluation of their neuroprotection against 6-hydroxydopamine- or H2O2 -induced oxidative damages in PC12 cells, a neuron-like rat pheochromocytoma cell line. Initial screening identified compounds 10 and 11 having low cytotoxicity but conferring remarkable protection on PC12 cells from oxidative-mediated damages. Further studies demonstrated that both compounds upregulated a battery of antioxidant genes as well as corresponding genes’ products. Significantly, silence of Nrf2 expression abolishes cytoprotection of 10 and 11, indicating targeting Nrf2 activation is pivotal for their cellular functions. Taken together, the two lead compounds discovered here with potent neuroprotective functions against oxidative stress via Nrf2 activation merit further development as therapeutic or chemopreventive candidates for neurodegenerative disorders.

Sodium is the most abundant alkali metal in the Earth’s crust and the ocean. However, organosodium compounds have long been considered inferior to organolithium compounds, which have instead dominated synthetic organic chemistry during the last century. Despite being largely neglected because of their reactive nature, it is worth re-exploring organosodium chemistry, in light of the growing demand for sustainable syntheses without recourse to less abundant elements such as lithium. Herein, we demonstrate that, contrary to common belief, organosodium compounds can be easily prepared from aryl chlorides or (hetero) arenes and easy-to-handle sodium dispersion and, after being transmetallated to the corresponding zinc and boron compounds, they readily participate in the Negishi and Suzuki-Miyaura cross-coupling reactions, fundamental carbon-carbon bond-forming reactions in organic synthesis. Direct coupling reactions with organosodium species were also possible.
