A full account of the total synthesis of aspidostomide B, C, their analogs and our synthetic efforts towards the synthesis of aspidostomide D, which led to the synthesis of regioisomeric N-Me aspidostomide D, its analogs via epoxide opening strategy is presented. The synthesis of regioisomeric N-Me aspidostomide D involves an efficient, five-step sequence, with 36.3% overall yield, starting from 3,4,5-tribromo-1H-pyrrole-2-carboxylic acid. The key features of this protocol are intramol. cyclization, dehydration, oxidation, and a Lewis acid-mediated regioselective epoxide ring opening by C-3 position of 2,5-dibromo-1H-indole to furnish the title compounds

Ye, Wenjun published the artcileDesign, synthesis and biological evaluation of novel triazoloquinazolinone and imidazoquinazolinone derivatives as allosteric inhibitors of SHP2 phosphatase, Synthetic Route of 22483-09-6, the main research area is melanoma SHP2 phosphatase triazoloquinazolinone imidazoquinazolinone; SHP2; allosteric inhibitors; antitumor activity; synthesis.

A series of novel triazoloquinolinone and imidazoquinazolinone derivatives were designed and synthesized, and their biol. activities against SHP2 protein and melanoma A357 cell line were evaluated in vitro. The results show that some target compounds have moderate to excellent inhibitory activity on SHP2 protein and melanoma A357 cell line. Structure-activity relationships (SARs) showed that both imidazoquinazolinone and triazoloquinazolinone derivatives have good SHP2 protein kinase and melanoma cell line A357 inhibitory activity. The results of mol. docking also showed that the cores of imidazoquinazolinone and triazoloquinazolinone have a certain affinity for SHP2 protein at the same time. Compared with SHP244, the target compounds have quite good liver microsomal stability and has more drug potential. The most promising compound has a strong inhibitory effect on the melanoma cell line A357 at 100 μM (76.15% inhibition).

Pichon, Maeva M. published the artcileTight-binding inhibition of jack bean α-mannosidase by glycoimidazole clusters, Quality Control of 22483-09-6, the main research area is tight binding jack bean mannosidase glycoimidazole cluster inhibition.

The best multivalent effects observed in glycosidase inhibition have been achieved so far with jack bean α-mannosidase (JBα-man) using iminosugar clusters based on weakly binding mismatching active-site-directed inhibiting epitopes (inhitopes) in the D-gluco series. Here, we synthesize and evaluate as JBα-man inhibitors a series of mono- to 14-valent glycoimidazoles with inhitopes displaying inhibition values up to the range of hundreds of nMs to study the impact of inhitope affinity on the multivalent effect. The most potent inhibitor of the series, a 14-valent mannoimidazole derivative, inhibits JBα-man with a nanomolar Ki value (2 ± 0.5 nM) and binding enhancements observed are, at best, relatively small (up to 25-fold on a valency-corrected basis). The results of this study support the fact that JBα-man-inhitope affinity and the strength of the inhibitory multivalent effect evolve in the opposite direction. The major impact of the glycoimidazole-based inhitope is found on the binding scenario; most of the synthesized mannoimidazole clusters as well as a 14-valent glucoimidazole derivative prove to be tight binding inhibitors of JBα-man.

Zhang, Hong published the artcileCytotoxicity and degradation product identification of thermally treated ceftiofur, Name: 2,2-Dimethoxyethanamine, the main research area is ceftiofur cytotoxicity thermal treatment cell proliferation.

Ceftiofur (CEF) is a cephalosporin antibiotic and is a commonly used drug in animal food production As a heat-labile compound, the residual CEF toxicity after thermal treatment has rarely been reported. This study was to investigate the potential toxicity of thermally treated CEF and determine the toxic components. By cytotoxicity tests and liquid chromatog.-mass spectrometry (LC-MS) assays, the cytotoxicity of the thermally treated CEF (TTC) and the components of TTC was identified, resp. Our results showed that TTC exhibited significantly increased toxicity compared with CEF towards LO2 cells by inducing apoptosis. Through LC-MS assays, we identified that the toxic compound of TTC was CEF-aldehyde (CEF-1). The IC50 value of CEF-1 on LO2 cells treated for 24 h was 573.1μg mL-1, approx. 5.3 times lower than CEF (3052.0μg mL-1) and 3.4 times lower than TTC (1967.0μg mL-1). Moreover, we found that CEF-1 was also present in thermally treated desfuroylceftiofur (DFC), the primary metabolite of CEF, indicating that residual CEF or DFC could produce CEF-1 during the heating process. These findings suggest that CEF-1 is a newly identified toxic compound, and CEF-1 may pose a potential threat to food safety or public health.

He, Nianzhe published the artcileDiscovery of selective Mcl-1 inhibitors via structure-based design and structure-activity relationship analysis, Product Details of C4H11NO2, the main research area is cervical cancer Mcl1 Bcl2 anticancer apoptosis structure activity relationship; Apoptosis; Cancer; Mcl-1; Protein–protein interaction.

Based on Nap-1, a Mcl-1/Bcl-2 dual inhibitor reported by our group, we carried out a structure-guided mol. design and structure-activity relationship (SAR) anal. to study structural features contributing to Mcl-1 binding selectivity and affinity. A series of derivatives of Nap-1 with various pharmacophores were synthesized and among them a dual Mcl-1/Bcl-2 inhibitor A4 with enhanced affinities (IC50 = 0.15 μM for Mcl-1, 0.43 μM for Bcl-2) and a selective Mcl-1 inhibitor B9 with a 20-fold selectivity over Bcl-2 (IC50 = 0.51 μM vs 9.46 μM) were obtained by enzyme linked immunosorbent assay (ELISA). The SAR data and binding modes of A4 and B9 investigated by 2D-NMR derived docking study illustrated that p2 pockets exhibiting different geometry and binding features between Mcl-1 and Bcl-2 contribute to specific binding properties of Mcl-1. In addition, apoptosis-inducing potencies of A4 and B9 were consistent with their binding selectivity determined in vitro.

Gerdt, Philipp published the artcileAlternating Terpolymers through Cyclopolymerization and Subsequent Orthogonal Functionalization, Quality Control of 22483-09-6, the main research area is alternating terpolymer cyclopolymn orthogonal functionalization; Alternating Polymerization; Orthogonal Functionalization; Postmodification; RAFT Polymerization; Radical Polymerization.

A method for the synthesis of functionalized alternating copolymers by reversible deactivation radical polymerization was developed. Copolymerization by reversible addition-fragmentation chain transfer of hexenyl vinyl ether with a novel fluorinated divinyl monomer yields alternating cyclopolymers that can be chemoselectively modified by three distinct orthogonal functionalization reactions. Along the thiol-ene click reaction and amidation, a third functionalization was achieved via NHC-catalyzed transesterification or acylation resulting in a small library of ABC-type alternating terpolymers.
