Zeytun, Ebru;Altintop, Mehlika D.;Sever, Belgin;Ozdemir, Ahmet;Ellakwa, Doha E.;Ocak, Zeynep;Ciftci, Halil I.;Otsuka, Masami;Fujita, Mikako;Radwan, Mohamed O. research published 《 A New Series of Antileukemic Agents: Design, Synthesis, In Vitro and In Silico Evaluation of Thiazole-Based ABL1 Kinase Inhibitors》, the research content is summarized as follows. After the approval of imatinib, more than 25 antitumor agents targeting kinases have been approved, and several promising candidates are at various stages of clin. evaluation. Due to the importance of the thiazole scaffold in targeted anticancer drug discovery, the goal of this work is to identify new thiazolyl hydrazones as potent ABL1 kinase inhibitors for the management of Chronic Myeloid Leukemia (CML). New thiazolyl hydrazones (2a-p) were synthesized and investigated for their cytotoxic effects on the K562 CML cell line. Compounds 2h, 2j and 2l showed potent anticancer activity against K562 cell line. The cytotoxic effects of these compounds on other leukemia (HL-60, MT-2 and Jurkat) and HeLa human cervical carcinoma cell lines were also investigated. Furthermore, their cytotoxic effects on Mitogen-Activated Peripheral Blood Mononuclear Cells (MA-PBMCs) were evaluated to determine their selectivity. Due to its selective and potent anticancer activity, compound 2j was benchmarked for its apoptosis-inducing potential on K562 cell line and inhibitory effects on eight different Tyrosine Kinases (TKs), including ABL1 kinase. In order to investigate the binding mode of compound 2j into the ATP binding site of ABL1 kinase (PDB: 1IEP), a mol. docking study was conducted using MOE 2018.01 program. The QikProp module of Schrodinger′s Mol. modeling package was used to predict the pharmacokinetic properties of compounds 2a-p. 4-(4-(Methylsulfonyl)phenyl)-2-[2-((1,3-benzodioxol-4-yl)methylene)hydrazinyl]thiazole (2j) showed antiproliferative activity against K562 cell line with an IC₅₀ value of 8.87±1.93 μM similar to imatinib (IC₅₀ = 6.84±1.11μM). Compound 2j was found to be more effective than imatinib on HL-60, Jurkat and MT-2 cells. Compound 2j also showed cytotoxic activity against HeLa cell line similar to imatinib. The higher selectivity index value of compound 2j than imatinib indicated that its antiproliferative activity was selective. Compound 2j also induced apoptosis in K562 cell line more than imatinib. Among eight TKs, compound 2j showed the strongest inhibitory activity against ABL1 kinase enzyme (IC₅₀= 5.37±1.17μM). According to mol. docking studies, compound 2j exhibited high affinity to the ATP binding site of ABL1 kinase, forming significant intermol. interactions. On the basis of in silico studies, this compound did not violate Lipinski′s rule of five and Jorgensen′s rule of three. Compound 2j stands out as a potential orally bioavailable ABL1 kinase inhibitor for the treatment of CML.

Zhang, Fang;Lin, Yiyu;Min, Wenjian;Hou, Yi;Yuan, Kai;Wang, Jin;Yang, Peng research published 《 Computational discovery, structural optimization and biological evaluation of novel inhibitors targeting transient receptor potential vanilloid type 3 (TRPV3)》, the research content is summarized as follows. Transient receptor potential vanilloid type 3 (TRPV3) is a Ca2+ permeable nonselective cation channel and expressed abundantly in skin keratinocytes. TRPV3 emerges as an attractive target for treatment of pruritic, inflammatory, pain and skin-related diseases. However, only a few reports of TRPV3 inhibitors exist at present besides some patents. Therefore, TRPV3 research has always been fraught with challenges. Through a combination of virtual screening and biol. evaluation, compound P1 (10μM) was identified as a top hit with 34.5% inhibitory effect on 2-APB (1 mM)-evoked currents of mTRPV3-WT. Further structural optimization provided the inhibitor PC5 with the best activity (IC50 = 2.63 ± 0.28μM), and point mutation assays indicated that amino acids V629 and F633 are crucial for the binding of PC5 and TRPV3. In summary, these newly discovered inhibitors could serve as promising lead compounds for the development of TRPV3 inhibitors in the future.

A phthalonitrile-containing monomer derived from a plant oil (anethole) has been successfully synthesized by a facile two-step reaction in an overall yield of 84%. Upon high temperature, this monomer is converted to a cured phthalocyanine resin in the presence of a catalyst, 4,4′-bis(3-aminophenoxy)diphenyl sulfone (m-BAPS).

Two low m.p. phthalonitrile monomers (EPN and EEPN) containing flexible glycidyl groups were synthesized using hydroxyl-containing phthalonitrile and epichlorohydrin as raw materials.

Then each of them was blended with 4-(4-aminophenoxy)-phthalonitrile (APPN) and cured to obtain two kinds of amine-catalytic phthalonitrile-based crosslinked polymers. DSC results showed that two blending systems underwent a two-stage polymerization process with the increase of curing temperature Rheol. measurements exhibited that the introduction of glycidyl groups to phthalonitrile resin could greatly improve its processability. Moreover, after thermal cured at 300 °, the resulting phthalonitrile resins exhibited excellent mech. performance, thermal and thermo-oxidative stability.

Zhang, Lingling;Guo, Yu;Hao, Rui;Shi, Yafei;You, Hongjun;Nan, Hu;Dai, Yanzhu;Liu, Danjun;Lei, Dangyuan;Fang, Jixiang research published 《 Ultra-rapid and highly efficient enrichment of organic pollutants via magnetic mesoporous nanosponge for ultrasensitive nanosensors》, the research content is summarized as follows. Currently, owing to the single-mol.-level sensitivity and highly informative spectroscopic characteristics, surface-enhanced Raman scattering (SERS) is regarded as the most direct and effective detection technique. However, SERS still faces several challenges in its practical applications, such as the complex matrix interferences, and low sensitivity to the mols. of intrinsic small cross-sections or weak affinity to the surface of metals. Here, we show an enrichment-typed sensing strategy with both excellent selectivity and ultrahigh detection sensitivity based on a powerful porous composite material, called mesoporous nanosponge. The nanosponge consists of porous β-cyclodextrin polymers immobilized with magnetic NPs, demonstrating remarkable capability of effective and fast removal of organic micropollutants, e.g., ∼90% removal efficiency within ∼1 min, and an enrichment factor up to ∼103. By means of this current enrichment strategy, the limit of detection for typical organic pollutants can be significantly improved by 2∼3 orders of magnitude. Consequently, the current enrichment strategy is proved to be applicable in a variety of fields for portable and fast detection, such as Raman and fluorescent sensing.
