In this study, a series of benzimidazole-rhodanine conjugates were designed, synthesized and investigated for their topoisomerase II (Topo II) inhibitory and cytotoxic activities. The results from Topo II-mediated pBR322 DNA relaxation and cleavage assays showed that the synthesized compounds might act as Topo II catalytic inhibitors. Certain compounds displayed potent Topo II inhibition at 10 muM. The cytotoxic activities of these compounds against HeLa, A549, Raji, PC-3, MDA-MB-201, and HL-60 cancer cell lines were evaluated. The results indicated that these compounds exhibited strong antiproliferative activity. A good relationship was observed between the Topo II inhibitory potency and the cytotoxicity of these compounds The structure-activity relationship revealed that the electronic effects, the Ph group, and the rhodanine moiety were particularly important for the Topo II inhibitory potency and cytotoxicity.

Chen, Xin published the artcile1,2-Benzothiazine 1,1-dioxide carboxylate derivatives as novel potent inhibitors of aldose reductase, Recommanded Product: 4-Bromo-1-(bromomethyl)-2-fluorobenzene, the publication is Bioorganic & Medicinal Chemistry (2011), 19(23), 7262-7269, database is CAplus and MEDLINE.

Due to the importance of aldose reductase (ALR2) as a potential drug target in the treatment of diabetic complications, there are increasing interests in design and synthesis of ALR2 inhibitors. 1,2-Benzothiazine-4-acetic acid 1,1-dioxide derivatives were prepared and investigated for their inhibition activity. Most of these derivatives were active with IC₅₀ values ranging from 0.11 μM to 10.42 μM, and 2-[2-(4-bromo-2-fluorobenzyl)-1,1-dioxido-2H-1,2-benzothiazin-4(3H)-ylidene]acetic acid showed the most potent inhibition activity. Further, SAR and docking studies suggest that in comparison with the α,β-unsaturated derivatives, the saturated carboxylic acid derivatives had a greater binding affinity with the enzyme and thus an enhanced inhibition activity. Therefore, development of more powerful ARIs based on benzothiazine 1,1-dioxide by stereo-controlled synthesis could be expected.

Ruthenium(II)-catalyzed meta-selective C-H (di)fluoromethylation was accomplished by phosphine and carboxylate cooperation. The remote C-H functionalization was characterized by ample substrate scope, thereby setting the stage for meta-(di)fluoromethylation through facile C-H cleavage. Thus, 2-phenylpyridine reacted withBrCF₂CO₂Et in the presence of ruthenium catalyst I and phosphine P(C₆H₄CF₃-4)₃ to give pyridinyldifluoroacetate II in 71% yield.

Wang, Kai published the artcileSynthesis of Diboronic Acid-Based Fluorescent Probes for the Sensitive Detection of Glucose in Aqueous Media and Biological Matrices, Related Products of bromides-buliding-blocks, the publication is ACS Sensors (2021), 6(4), 1543-1551, database is CAplus and MEDLINE.

Reliable and accurate glucose detection in biol. samples is of great importance in clin. diagnosis and medical research. Chem. probes are advantageous in simple operation and flexible design, especially for the development of fluorescent probes. Anthracene-based diboronic acid (P-DBA) has shown potential in glucose probing because of its high sensitivity. However, poor solubility limits its applications in aqueous media. In this work, we systemically modify P-DBA by introducing fluoro (F-), chloro (Cl-), methoxyl (MeO-), or cyano (CN-) substituents. Among these probes, the cyano-substituted probe (CN-DBA) displays the highest glucose-binding constant (6489.5 M^-1, 33% MeOH). More importantly, it shows good water solubility in the aqueous solution (0.5% MeOH), with ultrasensitive recognition with glucose (LOD = 1.51 μM) and robust sensing from pH 6.0 to 9.0. Based on these features, the CN-DBA is finally applied to detect glucose in cell lysates and plasma, with satisfactory recovery and precision. These results demonstrate that CN-DBA could serve as an accurate, sensitive fluorescent probe for glucose assays in biol. samples.

Liu, Xiaobo published the artcileCrowding-Induced Unconventional Phase Behaviors in Dendritic Rodlike Molecules via Side-Chain Engineering, HPLC of Formula: 957061-13-1, the publication is ACS Macro Letters (2021), 10(7), 844-850, database is CAplus and MEDLINE.

Dendritic mols. with a fanlike or conelike conformation are common mol. building blocks to construct supramol. columnar or spherical phases. Although it is well-accepted that the preferred mol. conformation of dendritic mols. dictates their packing schemes, manipulation of this crucial parameter usually requires significant changes in mol. structures and tedious synthetic efforts. Herein, we report a simple yet highly efficient strategy to tune the mol. conformation of dendritic rodlike mols. by adjusting the length of alkyl side chains tethered to the rods. Strikingly, tiny chem. structure differences can largely change the “crowding” near the branching point to induce the “fanlike to conelike” conformational transitions and thus result in the formation of diverse supramol. structures, including the columnar phase, double gyroid phase, and the unconventional Frank-Kasper σ and A15 phases. Our study provides a practical platform for further investigation of unconventional structure formation and phase transitions in soft matter.

Luo, Qi published the artcileSynthesis of Conjugated Main-Chain Ferrocene-Containing Polymers through Melt-State Polymerization, Synthetic Route of 303734-52-3, the publication is Organometallics (2019), 38(15), 2972-2978, database is CAplus.

Two kinds of conjugated main-chain ferrocene (Fc)-containing polymers, PFcT8 and PFcTP8, were successfully prepared through the facile melt-state polymerization (MSP) of corresponding monomers which combine the Fc motif with thiophene or thiophene-methane groups. The simple, low-cost MSP was chosen as the method, while thiophene or thiophene-methane groups served as reactive sites for its feature of easy polymerization by a simple heating process. The prepared metallopolymers were characterized by ¹H NMR, FTIR, and photochem. and electrochem. anal., metal content, and thermal stability. The results show that metallopolymers with a regular backbone and nearly quant. metal content were obtained. In addition, the metallopolymer PFcTP8 has the smallest optical band gap (absorption edge at 1100 nm) and high thermal stability among reported Fc-containing polymers, which indicates the thiophene-methane-based Fc-containing structure is a good candidate to construct functional polymers through MSP. The low band gap and high thermal stability of prepared conjugated metallopolymers show their potential application in conducting materials with high working temperature
