Data on free and bound volatile compounds in six Ribes nigrum L. blackcurrant cultivars

The data investigated 198 volatile compounds of six currant cultivars grown in China which is analyzed by SPME?GC?MS. Volatile compounds in these currant samples were identified by two methods, comparing retention indices with reference standards and matching mass spectrum in the NST11 library. A synthetic currant matrix prepared according to the currant juice condition were extracted and analyzed using the same extraction procedure as the currant samples. The standard curve was generated for quantification of volatile compounds. For the volatiles without the available standard, the data provided consulting standards that had the same carbon atom or the similar functional structure for quantification. Further interpretation and discussion can be seen in article entitled ?Characterization of Free and Bound Volatile Compounds in Six Ribes nigrum L. Blackcurrant Cultivars? (Liu et al., 2018) [1].

A thiadiazole reduces the virulence of xanthomonas oryzae pv. Oryzae by inhibiting the histidine utilization pathway and quorum sensing

Thiazole, isothiazole, thiadiazole and their derivatives are widely thought to induce host defences against plant pathogens. In this article, we report that bismerthiazol, a thiadiazole molecule, reduces disease by inhibiting the histidine utilization (Hut) pathway and quorum sensing (QS). Bismerthiazol provides excellent control of bacterial rice leaf blight (BLB) caused by Xanthomonas oryzae pv. oryzae (Xoo), but does not greatly inhibit Xoo growth in vitro. According to RNA-sequencing analysis, the transcription of the Hut pathway genes of Xoo ZJ173 was inhibited after 4.5 and 9.0 h of bismerthiazol treatment. Functional studies of hutG and hutU indicated that the Hut pathway had little effect on the growth and bismerthiazol sensitivity of Xoo in vitro, but significantly reduced the aggregation of Xoo cells. Deletion mutants of hutG or hutU were more motile, produced less biofilm and were less virulent than the wild-type, indicating that the Hut pathway is involved in QS and contributes to virulence. The overexpression of the hutG-U operons in ZJ173 reduced Xoo control by bismerthiazol. Bismerthiazol did not inhibit the transcription of Hut pathway genes, QS or virulence of the bismerthiazol-resistant strain 2-1-1. The results indicate that bismerthiazol reduces Xoo virulence by inhibiting the Hut pathway and QS.

Covalent inhibitors of the GTPase KRASG12C: a review of the patent literature

Introduction: KRAS is one of the most important oncology drug targets, playing a pivotal role in the initiation and progression of many human tumors. It has long been held undruggable due to many previously failed attempts to both directly and indirectly target this challenging GTPase protein family. Areas covered: This review covers patent applications claiming inhibitors of the mutant GTPase KRASG12C that act via covalent modification of cysteine at codon 12 in the period of 2014 to the present. A total of 37 PCT applications from 9 applicants are evaluated, with the discussion organized alphabetically by assignee name. Expert opinion: The last 5 years have seen an explosion in interest around this important target with many companies aiming to capitalize on the breakthrough discovery of covalent allosteric inhibitors of the glycine to cysteine mutant form of the enzyme. The first agents from this effort have now entered clinical trials and preliminary data are encouraging with responses seen in both lung adenocarcinoma and colorectal cancer patients.

Asymmetric synthesis of sultams and sulfonamides via diastereoselective reduction of N-sulfonylimines

The diastereoselective reduction of both cyclic and acyclic camphor sulfonylimines was investigated. With cyclic camphor sulfonylimines 1, reduction using NaBH4 in methanol afforded the corresponding camphorsultams 2 in 92-95% yield as single diastereomers with the exception of 1c where debromination occurred prior to reduction. For the large scale preparation of camphorsultam 1a and its derivatives, important chiral auxiliaries in asymmetric synthesis, reduction with NaBH4 is the reagent of choice. Reduction of acyclic camphor sulfonylimines 7 to camphorsulfonamides 8 with the bulky reducing reagent, LiAl(OBu-i)3H afforded the highest de’s (>90% de) and yields 90-95%.

Synthesis and investigations of the absorption spectra of hetarylazo disperse dyes derived from 2,4-quinolinediol

Synthesis of some novel hetarylazoquinoline dyes was achieved by diazotisation of nine heterocyclic amines using nitrosyl sulphuric acid, coupling with 2,4-quinolinediol. These dyes were characterized by UV-vis, FT-IR and 1H NMR spectroscopic techniques and elemental analysis. Visible absorption spectra of the dyes are discussed, both the effects of varying pH and solvent upon the absorption ability of azoquinolines. The colour of the dyes was discussed with respect to the nature of the heterocyclic ring and to the substituents therein. Temperature and concentration effects on the visible absorption maxima of the dyes are also reported.

Histone acetyltransferase inhibitors: An overview in synthesis, structure-activity relationship and molecular mechanism

Acetylation, a key component in post-translational modification regulated by HATs and HDACs, is relevant to many crucial cellular contexts in organisms. Based on crucial pharmacophore patterns and the structure of targeted proteins, HAT inhibitors are designed and modified for higher affinity and better bioactivity. However, there are still some challenges, such as cell permeability, selectivity, toxicity and synthetic availability, which limit the improvement of HAT inhibitors. So far, only few HAT inhibitors have been approved for commercialization, indicating the urgent need for more successful and effective structure-based drug design and synthetic strategies. Here, we summarized three classes of HAT inhibitors based on their sources and structural scaffolds, emphasizing on their synthetic methods and structure?activity relationships and molecular mechanisms, hoping to facilitate the development and further application of HAT inhibitors.

Tert-Butyl 1,5-bis(4-(benzo[d]isothiazol-3-yl)piperazin-1-yl)-1,5- dioxopentan-2-ylcarbamate urea/thiourea derivatives as potent H +/K+-ATPase inhibitors

Amino acids are known to possess variable efficacy against ulceration. Considering the good antiulcer activity of amino acids, a series of urea/thiourea derivatives of glutamic acid conjugated benzisothiazole analogue 3a-u with various substituents on aryl ring were synthesized, spectroscopically characterized and evaluated for in vitro H+/K+-ATPase inhibition. Majority of the compounds possessed potency compared to that of omeprazole, a reference drug. In particular, methoxy derivatives 3p-u were the most active compounds possessing a significant 15-fold increase for para substituent thus, contributing positively to gastric H+/K +-ATPase inhibition.
