20(R)-25-hydroxyprotopanaxadiol (25-OH-PPD) is a natural compound showing a variety of anti-tumor effects. In an attempt to search for a new anti-cancer compound with higher antitumor activities, we designed and synthesized a series of 25-OH-PPD derivatives. Cytotoxicity assay of these derivatives towards MCF-7, A549, U87, HO-8901, Hela cancer cell lines and normal IOSE144 cell lines were tested by MTF assay. Results showed that compared with compound 25-OH-PPD, Compounds 4, 5, 6, 10, 11 showed strong anticancer activity, and all compounds showed low toxicity or no toxicity for normal cells. In particular, compound 6 exhibited the best anti-tumor activity in all cancer cell lines (MCF-7, A549, U87, HO-8901, and Hela) with IC50 values of 5.04 mu M, 1.36 mu M, 3.24 mu M, 3.47 mu M, 4.57 mu M, respectively. Among the five cell lines, all the compounds showed strong inhibition on A549 cells. Further studies showed that Compound 6 significantly inhibited the proliferation of A549 cells by inducing apoptosis. Our results indicate that Compound 6 is a potential anticancer inhibitor and provides a theoretical basis for further research.

The 1,3-benzodioxol moiety present in safrole, apiole, and myristicin essential oils and benzodioxol derivatives have shown a wide range of biological activities including antiepileptic, analgesic, antituberculosis, and antimicrobial potentials. Here, we have tested the antibacterial and antioxidant activities of a series of benzodioxol derivatives. Twelve compounds of aryl acetate and acetic acid benzodioxol were evaluated against different types of bacterial strains, including Staphylococcus aureus, Escherichia coli, Enterococcus faecalis, and Pseudomonas aeruginosa using the broth dilution method, and the most potent compound was 3e, which exhibited the bacterial growth of with MICs of 125 (S. aureus), 250 (E. coli), 220 (E. faecalis), and 100 mu g/mL (P. aeruginosa). Our positive control, cinoxacin, had MICs of 250 (S. aureus), 250 (E. coli), 250 (E. faecalis), and 500 mu g/mL (P. aeruginosa). Antioxidant activity was evaluated for the synthesized compounds utilizing the DPPH assay. The 3a compound was the most active with an IC50 value of 21.44 mu g/mL, while the IC50 values of compounds 3b, 3e, and 3f were 96.07, 58.45, and 72.17 mu g/mL, respectively. In contrast, all compounds with the acetic acid functional group had weaker activity, with an IC50 range of 193.52-289.78 mu g/mL compared with the potent antioxidant agent Trolox (IC50 = 1.93 mu g/mL). In the present paper, new benzodioxol-based aryl acetate and acetic acid derivatives were evaluated for their antibacterial and antioxidant activities. The outcomes revealed that the antibacterial and antioxidant properties of some of the synthesized benzodioxol aryl acetate and acetic acid derivatives can be considered as valuable materials for the pharmaceutical industry. Thus, these molecules should be further evaluated in vivo as lead compounds for the discovery of new drug candidates.

The insect enzyme GH20 beta-N-acetyl-D-hexosaminidase OfHex1 represents an important chitinolytic enzyme found in the agricultural pest Ostrinia furnacalis (Guenee) and inhibition of this enzyme has been considered a promising strategy for the development of eco-friendly pesticides. In this article, based on the structure of the catalytic domains of OfHex1, a series of novel glycosyl triazoles were designed and synthesized via Cu-catalyzed azide-alkyne [3+ 2] cycloaddition reaction. To investigate the potency and selectivity of these glycosyl triazoles, the inhibition activities towards OfHex1 and HsHexB (human beta-N-acetylhexosaminidase B) were studied. Particularly compound 17c (OfHex1, K-i= 28.68 mu M; HsHexB, K-i > 100 mu M) exhibited a suitable activity and selectivity against OfHex1. Furthermore, the possible inhibitory mechanisms of 17c with OfHex1 were studied using molecular docking and MD simulations. The structure-activity relationship results as well as the formed binding patterns may provide promising insights into the further development of novel OfHex1 inhibitors.

Despite remarkable advances to promote regio- and stereoselective decarboxylative arylation of inactivated olefins with benzoic acid derivatives, methodologies involving hetero-substituted alkenes are still lacking. Herein, Pd-II-catalyzed decarboxylative Heck coupling of alpha-alkoxyacrylates with (hetero)aryl carboxylic acids for the stereocontrolled production of (Z)-beta-heteroarylated vinyl ethers is reported. This methodology offers a rational and step-economical route to the synthesis of attractive beta-arylated alpha-alkoxy alpha,beta-unsaturated carboxylates family which emerged as a relevant class of building blocks with different applications. Mechanistically, whereas electron rich benzoic acids undergo a Pd-II-catalyzed decarboxylation, electron-deficient substrates proceed through silver(I)-mediated decarboxylation, explaining thus the formation of stereoisomers (E) and (Z) of beta-arylated vinyl ethers in presence of these latter.

Objectives: To evaluate the performance of a high-throughput research assay for HIV drug resistance testing based on whole genome next-generation sequencing (NGS) that also quantifies HIV viral Load. Methods: Plasma samples (n = 145) were obtained from HIV-positive MSM (HPTN 078). Samples were analysed using clinical assays (the ViroSeq HIV-1 Genotyping System and the Abbott RealTime HIV-1 Viral Load assay) and a research assay based on whole-genome NGS (veSEQ-HIV). Results: HIV protease and reverse transcriptase sequences (n =142) and integrase sequences (n =138) were obtained using ViroSeq. Sequences from all three regions were obtained for 100 (70.4%) of the 142 samples using veSEQ-HIV; results were obtained more frequently for samples with higher viral Loads (93.5% for 93 samples with >5000 copies/mL; 50.0% for 26 samples with 1000-5000 copies/mL; 0% for 23 samples with <1000 copies/mL). For samples with results from both methods, drug resistance mutations (DRMs) were detected in 33 samples using ViroSeq and 42 samples using veSEQ-HIV (detection threshold: 5.0%). Overall, 146 major DRMs were detected; 107 were detected by both methods, 37 were detected by veSEQ-HIV only (frequency range: 5.0%-30.6%) and two were detected by ViroSeq only. HIV viral Loads estimated by veSEQ-HIV strongly correlated with results from the Abbott RealTime Viral Load assay (R-2 = 0.85; n = 142). Conclusions: The NGS-based veSEQ-HIV method provided results for most samples with higher viral Loads, was accurate for detecting major DRMs, and detected mutations at Lower Levels compared with a method based on population sequencing. The veSEQ-HIV method also provided HIV viral Load data.
