To evaluate the inhibition of by-products that exist in pretreated lignocellulose hydrolysate on bioethanol fermentation, quantitative structure-activity relationship (QSAR) models were established in the present study. These models have the potential to predict the fermentation inhibition to minimize the experimental effort. They also provided an innovative methodology for removing fermentation inhibitors purposefully and for optimizing pretreatment parameters and thus could enhance the bioethanol yield. The results indicated that the fermentation inhibition of phenolic aldehyde were stronger than that of phenolic acid followed by phenolic alcohol in which the fermentation inhibition was weakened by the existence of the methoxy group in the benzene ring. Meanwhile, the formation of the intramolecular hydrogen bonds of fermentation inhibitors also played an important role in weakening their fermentation inhibition. The individual fermentation inhibition of fermentation inhibitors was found strongly related to their molecular descriptors. Furthermore, ferulic acid was chosen as the representative inhibitor for the primary investigation on the combined fermentation inhibition of the various complex binary fermentation inhibitor mixtures, which co-existed in the lignocellulose hydrolysate. As indicated by the results, antagonism occurred mainly under the higher ferulic acid concentrations in the binary mixtures, while a simple additive effect was generated.

A general asymmetric deconstructive alkynylation of cyclic oximes with terminal alkynes was reported using copper/chiral cinchona alkaloid-based N,N,P-ligand catalysts and used to produce more than 60 examples of enantioenriched gamma- and delta-alkynyl nitriles in a highly functional group-compatible manner. A wide variety of low-cost terminal alkynes and easily available cyclic oximes with substituent diversity were found to be well tolerated with the current asymmetric transformation with good functional group tolerance. The resulting chiral alkynyl nitriles are intermediates, which could be converted into skeletally diverse chiral molecules, including delta-alkynyl amides, epsilon-alkenyl carbamate, and zeta-keto nitrile, under suitable reaction conditions.

The covalent functionalization of 2D transition metal dichalcogenides (TMDCs) with organic molecules exploiting the thiol conjugation approach is still a very controversial topic. We have synthesized thiolated tetraphenyl porphyrins, with and without hydroxyl groups in the phenyl substituents, which have been covalently attached to chemically exfoliated MoSe2 (ce-MoSe2) nanosheets. XPS and FTIR have revealed the formation of sulfo-selenide bridges, specifically on the edges of the ce-MoSe2, as confirmed by first principles calculations. The electrocatalytic activity of TMDCs in the hydrogen evolution reaction (HER) has been investigated after conjugation with the organic molecules. The HER activity is suppressed or enhanced according to the presence of mildly acidic hydroxyl groups in the attached molecules, since they provide a local proton relay boosting the production of H-2, especially under mildly acidic conditions (pH = 4.3). Moreover, the well-known light-harvesting properties of porphyrins have been exploited to improve significantly the light-assisted HER activity. Due to the formation of a type II heterojunction or Schottky contact between the molecules and the 2H and 1T MoSe2 nanosheets respectively, the hybrid materials show an improvement of the HER onset potential under illumination compared to the pristine material, without activity loss for more than 16 h.

Chiral acetylenic derivatives are found in many bioactive compounds and are versatile functional groups in organic chemistry. Here, we describe an enantioselective nickel/Lewis acid-catalyzed asymmetric propargylic substitution reaction from simple achiral materials under mild condition. The introduction of a Lewis acid cocatalyst is crucial to the efficiency of the transformation. Notably, we investigate this asymmetric propargylic substitution reaction for the development of a range of structurally diverse natural products. The power of this strategy is highlighted by the collective synthesis of seven biologically active compounds: (-)-Thiohexital, (+)-Thiopental, (+)-Pentobarbital, (-)-AMG 837, (+)-Phenoxanol, (+)-Citralis, and (-)-Citralis Nitrile.

Oxidation of benzylic position in alkylphenols with molecular oxygen in acidic conditions, which is very difficult because of the intense dimerization or polymerization, was investigated with various combinations of noble metal catalysts. The combination of Pt/C and Pd(CH3COO)(2) catalysts showed activity in the formation of p-hydroxybenzaldehyde formation from p-cresol. The best p-hydroxybenzaldehyde yield was 35%, which was obtained in 50 wt% aqueous acetic acid, Pt on carbon : Pd(CH3COO)(2) weight ratio = 1 : 2, at 353 K. From XRD, TEM-EDX and XAFS characterizations, the Pt and Pd species were totally reduced to Pt and Pd metal particles, respectively, in spite of the oxidative reaction conditions. Polymerized products (tar) of p-cresol formed with Pt/C catalyst and air can be the reductants for Pd(CH3COO)(2) into Pd metal. The catalysts or catalyst combinations without Pd degrees metal showed no activity in the formation of p-hydroxybenzaldehyde, suggesting that Pd is the active species. The effects of the air pressure and presence of radical scavenger were very small, suggesting that non-free-radical mechanism was involved.

An ‘on-water’ protocol has been developed for the synthesis of combretastatin A-4 (CA-4) analogues by cyclization of polarized triaryldivinyl ketones using hydrochloric acid as a promoter in 45-95% yields. The reaction time was reduced by about 30 times due to ultrasonic irradiation at ambient temperature. The other advantages of this new method are operational simplicity, easy workup, no column purification, and applicability on a gram-scale. It was shown that the amphiphilicity of the substrate and a low energy barrier of the reaction are a prerequisite for electrophilic and concerted reactions under aqueous and ambient conditions.

A halogen-lithium exchange reaction of (hetero)aromatic halides performed in the presence of various electrophiles such as aldehydes, ketones, Weinreb amides, and imines using BuLi as exchange reagent and a commercially available flow set-up is reported. The organolithiums generated in situ were instantaneously trapped with various electrophiles (Barbier conditions) resulting in the formation of polyfunctional (hetero)arenes. This method enables the functionalization of (hetero)arenes containing highly sensitive functional groups such as esters, which are not tolerated in batch conditions.

Prostate cancer (PCa) is a cancer that occurs in the prostate with high morbidity and mortality. Danggui Beimu Kushen Wan (DBKW) is a classic formula for patients with difficult urination including PCa. This study aimed to investigate the molecular mechanisms of DBKW for PCa. We obtained DBKW compounds from our previous reviews. We identified potential targets for PCa from literature search, currently approved drugs and Open Targets database and filtered them by protein-protein interaction network analysis. We selected 26 targets to predict three cancer-related pathways. A total of 621 compounds were screened via molecular docking using PyRx and AutoDock Vina against 21 targets for PCa, producing 13041 docking results. The binding patterns and positions showed that a relatively small number of tight-binding compounds from DBKW were predicted to interact strongly and selectively with three targets. The top five high-binding-affinity compounds were selected to generate a network, indicating that compounds from all three herbs had high binding affinity against the 21 targets and may have potential biological activities with the targets. DBKW contains multi-targeting agents that could act on more than one pathway of PCa simultaneously. Further studies could focus on validating the computational results via experimental studies.

A conceptually new and synthetically valuable radical Smiles rearrangement reaction is reported under undivided electrolytic conditions. This protocol employs an entirely new strategy for the electrochemical radical Smiles rearrangement. Remarkably, an amidyl radical generated from the cleavage of the N-O bond under reductive electrolytic conditions plays a crucial role in this transformation. Various hydroxylamine derivatives bearing different substituents are suitable in this electrochemical transformation, furnishing the corresponding amides in up to 86% yield.
