To find efficient and broad-spectrum viral agents, a series of purine nucleoside derivatives containing sulfa ethylamine moieties was designed and synthesized, and their antiviral activities against tobacco mosaic virus (TMV), cucumber mosaic virus (CMV), and potato virus Y (PVY) were evaluated. Some target compounds displayed good antiviral activities. Among them, compound I showed excellent protective activity against CMV and PVY with 50% effective concentration values (EC₅₀) of 137 and 209μg/mL, resp., which were better than that of the control agent ningnanmycin (508 and 431μg/mL). Moreover, the EC₅₀ value of compound I for the inactivating activity against TMV was 48μg/mL, which was better than that of ningnanmycin (88μg/mL). In addition, compound I not only destroyed the structure of the TMV virus but also had a good interaction with the coat protein of the TMV virus. Therefore, compound I may further destroy the structure of the virus by binding to the coat protein of the TMV virus, thereby weakening the infectivity of the virus.

Mei, Leixia published the artcileSupramolecular self-assembly of fluorescent peptide amphiphiles for accurate and reversible pH measurement, Quality Control of 42074-68-0, the publication is Organic & Biomolecular Chemistry (2019), 17(4), 939-944, database is CAplus and MEDLINE.

We report the synthesis and self-assembly of fluorescent peptide amphiphiles (NBD-PA) composed of a fluorescent NBD probe and a peptide derivative VVAADD with a C₁₂-alkyl-chain as the linker (NBD-C₁₂-VVAADD). The self-assembly of NBD-PA formed beta-sheet structures at neutral pH in aqueous solution, contributed to an âˆ?0-fold increase in the fluorescence and quantum yield of NBD mols., and conferred a supramol. hydrogel with excellent viscoelastic properties, while gel-to-sol transition of NBD-PA occurred rapidly when the pH value was adjusted to strongly alk. (e.g. pH 11). Through the pH-responsive self-assembly behavior, we further explored the relation between fluorescence of NBD-PA and pH values. Interestingly, the fluorescence of the NBD-PA system exhibited an excellent sigmoidal function relation (R² = 0.9999) with the alk. pH values, which enabled accurate pH measurement regardless of salt types and ionic strength of solvents. Furthermore, the fluorescence of NBD-PA was fully reversible upon cycles of pH shifts, with the chem. structure of NBD-PA well-maintained throughout the process. These features of NBD-PA would facilitate the design of in situ pH detection systems as well as pH-responsive actuators for various applications in future.

Pyrazole derivates were a kind of compounds with high and broad-spectrum activity. In order to find heterocyclic carboxamide derivatives with high activity, this kind of compounds were further studied. A series of N-(1,4-disubstituted pyrazole-yl)-heterocyclic carboxamide derivatives were synthesized. All target compounds were bioassayed in vitro against three kinds of phytopathogenic fungi (Gibberella zeae, Fusarium oxysporum, Cytospora mandshurica). The preliminary results indicated that most of the synthesized compounds possessed some antifungal activity against these three tested fungi at 50 mg/L, among which compound 9j displayed 71.0% inhibition activity against G. zeae at 50 mg/L and compound 9l displayed 55.7% inhibition activity against C. mandshurica at 50 mg/L. The mol. structures of the target compounds could be optimized based on the designed compounds

Ma, Hao published the artcileDesign and Synthesis of Bridging Chiral p-t-Butylcalix[4]arene Tetrahydroisoquinolines and Their Application in Henry Reaction as Chiral Organocatalysts, Application In Synthesis of 21286-54-4, the publication is ChemistrySelect (2019), 4(15), 4642-4646, database is CAplus.

A pair of bridging chiral p-t-butylcalix[4]arenes (2a and 2b) (were) synthesized from 1 through homologous anionic ortho-Fries rearrangement, and optically resolved with (1S)-(+)-10-camphorsulfonyl chloride as chiral auxiliary. Bridging chiral p-t-butylcalix[4]arene tetrahydroisoquinolines (9a and 9b) as chiral organocatalysts for Henry reaction were designed and synthesized through the structural modification of 2a and 2b, resp. Compared to the catalytic enantioselectivity of the unmodified tertiary amine (4b: �% ee and 63% yield), those of the tetrahydroisoquinoline derivatives (9b: up to 13.4% ee and 96% yield) were distinctly enhanced. Although the increase magnitude of the catalytic ee is not remarkable, these catalytic results prove that the conformation inversion of calix[4]arene skeleton and the rotational freedom reduction of catalytic amine group indeed bring beneficial effects on the catalytic stereoselectivity.

A series of N,S-diarylsulfonamides was identified as hCCR2 receptor antagonists but suffered from high plasma protein binding resulting in a >100 fold shift in activity in a functional GTPγS assay run in tandem in the presence and absence of human serum albumin. Introduction of an aryl amide with ethylenediamine linker led to compounds with reduced shifts and improved activity in whole blood.

Gabor, Krisztina published the artcileDivergent roles of CprK paralogs from Desulfitobacterium hafniense in activating gene expression, Recommanded Product: 3-Chloro-4-hydroxyphenylacetic acid, the publication is Microbiology (Reading, United Kingdom) (2008), 154(12), 3686-3696, database is CAplus and MEDLINE.

Gene duplication and horizontal gene transfer play an important role in the evolution of prokaryotic genomes. We have investigated the role of three CprK paralogs from the cAMP receptor protein-fumarate and nitrate reduction regulator (CRP-FNR) family of transcriptional regulators that are encoded in the genome of Desulfitobacterium hafniense DCB-2 and possibly regulate expression of genes involved in the energy-conserving terminal reduction of organohalides (halorespiration). The results from in vivo and in vitro promoter probe assays show that two regulators (CprK1 and CprK2) have an at least partially overlapping effector specificity, with preference for ortho-chlorophenols, while meta-chlorophenols proved to be effectors for CprK4. The presence of a potential transposase-encoding gene in the vicinity of the cprK genes indicates that their redundancy is probably caused by mobile genetic elements. The CprK paralogs activated transcription from promoters containing a 14 bp inverted repeat (dehalobox) that closely resembles the FNR-box. We found a strong neg. correlation between the rate of transcriptional activation and the number of nucleotide changes from the optimal dehalobox sequence (TTAAT-N₄-ATTAA). Transcription was initiated by CprK4 from a promoter that is situated upstream of a gene encoding a methyl-accepting chemotaxis protein. This might be the first indication of taxis of an anaerobic bacterium to halogenated aromatic compounds

Integrase is a validated drug target for anti-HIV-1 therapy. The second generation integrase inhibitors display π-stacking interaction ability with 3′-end nucleotide as a streamlined metal chelating pharmacophore. In this study, we introduced benzoxazin-3-one scaffold for integrase inhibitory potential as bioisostere replacement strategy of 2-benzoxazolinone. Mol. modeling studies revealed that amide functionality alongside oxadiazole heteroatoms and sulfur in the second position of oxadiazole ring could mimic the metal chelating pharmacophore. The halobenzyl ring occupies hydrophobic site created by the cytidylate nucleotide (DC-16). The most potent and selective compound displayed 110μM IC₅₀ with a selectivity index of more than 2.

Ramsbeck, Daniel published the artcileFirst insight into structure-activity relationships of selective meprin β inhibitors, SDS of cas: 32333-53-2, the publication is Bioorganic & Medicinal Chemistry Letters (2017), 27(11), 2428-2431, database is CAplus and MEDLINE.

The astacin proteases meprin α and β are emerging drug targets for treatment of disorders such as kidney failure, fibrosis or inflammatory bowel disease. However, there are only few inhibitors of both proteases reported to date. Starting from NNGH as lead structure, a detailed elaboration of the structure-activity relationship of meprin β inhibitors was performed, leading to compounds with activities in the lower nanomolar range. Considering the preference of meprin β for acidic residues in the P1′ position, the compounds were optimized. Acidic modifications induced potent inhibition and >100-fold selectivity over other structurally related metalloproteases such as MMP-2 or ADAM10.
