The first regioselective phenoxysulfonylation of alkynes with sodium sulfinate and phenol catalyzed by I-2/base has been uncovered. This metal-free, one-pot alkyne difunctionalization process provides various (Z)-beta-phenoxy vinylsulfones under mild reaction conditions. A variety of terminal as well as internal alkynes and sodium sulfinates and a wide range of phenols/thiophenols and naphthols are viable in this transformation. Green protocol and wide substrate scope are the remarkable characteristics of this multicomponent procedure.

A practical method for the synthesis of phenyl enol ethers is reported. The combination of a gold(I) catalyst and potassium carbonate selectively mediates the addition of phenols to propargylic alcohols/amines in a chemo-, regio-, and stereoselective fashion in high yield. The resulting enol ethers are formed exclusively with a Z-configuration and can be obtained from a wide array of phenols and propargylic alcohols or amines with the reaction showing excellent functional group tolerance.

Background The Dietary Approaches to Stop Hypertension (DASH) diet improves blood pressure in nonpregnant populations. We hypothesized that adherence to the DASH diet during pregnancy improves hemodynamic adaptations, leading to a lower risk of gestational hypertensive disorders. Methods and Results We examined whether the DASH diet score was associated with blood pressure, placental hemodynamics, and gestational hypertensive disorders in a population-based cohort study among 3414 Dutch women. We assessed DASH score using food-frequency questionnaires. We measured blood pressure in early-, mid-, and late pregnancy (medians, 95% range: 12.9 [9.8-17.9], 20.4 [16.6-23.2], 30.2 [28.6-32.6] weeks gestation, respectively), and placental hemodynamics in mid- and late pregnancy (medians, 95% range: 20.5 [18.7-23.1], 30.4 [28.5-32.8] weeks gestation, respectively). Information on gestational hypertensive disorders was obtained from medical records. Lower DASH score quartiles were associated with a higher mid pregnancy diastolic blood pressure, compared with the highest quartile (P<0.05). No associations were present for early- and late pregnancy diastolic blood pressure and systolic blood pressure throughout pregnancy. Compared with the highest DASH score quartile, the lower DASH score quartiles were associated with a higher mid- and late pregnancy umbilical artery pulsatility index (P <= 0.05) but not with uterine artery resistance index. No associations with gestational hypertensive disorders were present. Conclusions A higher DASH diet score is associated with lower mid pregnancy diastolic blood pressure and mid- and late pregnancy fetoplacental vascular function but not with uteroplacental vascular function or gestational hypertensive disorders within a low-risk population. Further studies need to assess whether the effects of the DASH diet on gestational hemodynamic adaptations are more pronounced among higher-risk populations.

The regioselectivity of hydroxyl radical addition to arenes was studied using a novel analytical method capable of trapping radicals formed after the first elementary step of reaction, without alteration of the product distributions by secondary oxidation processes. Product analyses of these reactions indicate a preference for o- over p-substitution for electron donating groups, with both favored over m-addition. The observed distributions are qualitatively similar to those observed for the addition of other carbon-centered radicals, although the magnitude of the regioselectivity observed is greater for hydroxyl. The data, reproduced by high accuracy CBS-QB3 computational methods, indicate that both polar and radical stabilization effects play a role in the observed regioselectivities. The application and potential limitations of the analytical method used are discussed.

Owing to the rapid rise in antibiotic resistance, infectious diseases have become serious threat to public health. There is an urgent need to develop new antimicrobial agents with diverse chemical structures and novel mechanisms of action to overcome the resistance. In recent years, Quinazoline-benzimidazole hybrids have emerged as a new class of antimicrobial agents active against S. aureus and M. tuberculosis. In the current study, we designed and synthesized fifteen new Quinazoline-benzimidazole hybrids and evaluated them for their antimicrobial activity against S. aureus ATCC 29213 and M. tuberculosis H37Rv. These studies led to the identification of nine potent antibacterial agents 8a, 8b, 8c, 8d, 8f, 8g, 8h, 8i and 10c with MICs in the range of 4-64 mu g/mL. Further, these selected compounds were found to possess potent antibacterial potential against a panel of drug-resistant clinical isolates which include methicillin and vancomycin-resistant S. aureus. The selected compounds were found to be less toxic to Vero cells (CC50 = 40->= 200 mu g/mL) and demonstrated a favourable selectivity index. Based on the encouraging results obtained these new benzimidazol-2-yl quinazoline derivatives have emerged as promising antimicrobial agents for the treatment of MDR-S. aureus and Mycobacterial infections.

Enynes are important motifs in bioactive compounds. They can be synthesized by alkyne-alkyne couplings for which a number of mechanisms have been suggested depending on catalyst type and dominant product isomers. Regarding bimetallic pathways, hydrometalations and anti-carbopalladations have been discussed to account for the formation of geminally substituted and (Z)-configured enynes, respectively. Here we report a bimetallic alkyne-alkyne coupling that yields (E)-configured enynes. An unusual type of acetylide Pd bridging was found in putative catalytic intermediates which is arguably responsible for the regio- and stereochemical reaction outcome. Mechanistic studies suggest that a double mu-kappa:eta(2) acetylide bridging enables a bimetallic syn-carbometalation. Interestingly, depending on the reaction conditions, it is also possible to form the geminal regioisomer as major product with the same catalyst. This regiodivergent outcome is explained by bi-versus monometallic reaction pathways.

One effective means to achieve inhibitor specificity for RAF kinases, an important family of cancer drug targets, has been to target the monomeric inactive state conformation of the kinase domain, which, unlike most other kinases, can accommodate sulfonamide-containing drugs such as vemurafenib and dabrafenib because of the presence of a unique pocket specific to inactive RAF kinases. We previously reported an alternate strategy whereby rigidification of a nonselective pyrazolo[3,4-d]pyrimidine-based inhibitor through ring closure afforded moderate but appreciable increases in selectivity for RAF kinases. Here, we show that a further application of the rigidification strategy to a different pyrazolopyrimidine-based scaffold dramatically improved selectivity for RAF kinases. Crystal structure analysis confirmed our inhibitor design hypothesis revealing that 21 engages an active-like state conformation of BRAF normally associated with poorly discriminating inhibitors. When screened against a panel of distinct cancer cell lines, the optimized inhibitor 21 primarily inhibited the proliferation of the expected BRAF(V600E)-harboring cell lines consistent with its kinome selectivity profile. These results suggest that rigidification could be a general and powerful strategy for enhancing inhibitor selectivity against protein kinases, which may open up therapeutic opportunities not afforded by other approaches.

4-Hydroxy-3-methyl-2(1H)-quinolone (1), a molecule known for a long time and recently discovered from a Brassicaceae plant Isatis tinctoria without providing sufficient evidence to support the structure, was isolated from a fermentation extract of Burkholderia sp. 3Y-MMP isolated from a soil by a Zn2+ enrichment culture. Detailed spectroscopic analyses by MS and NMR, combined with C-13 chemical shift comparison with literature values of the related compounds and a synthetic preparation of 1, allowed its first full NMR characterization and identification of 2-quinolone but not 2-quinolinol (2) as the preferred tautomer for this heterocyclic system. While the metal-chelating activity was negligible, compound 1 at 10 mu M, a concentration lower than that in liquid production cultures, quenched hydroxy radical-induced chemiluminescence emitted by luminol by 86%. Because some Burkholderia species are pathogenic to plants and animals, the above result suggests that 1 is a potential antioxidant to counteract reactive oxygen species-based immune response in the host organisms.
