Zhou, Yu;Li, Xiaoguang;Chen, Kerong;Ba, Qian;Zhang, Xu;Li, Jingquan;Wang, Jinfang;Wang, Hui;Liu, Hong research published 《 Structural optimization and biological evaluation for novel artemisinin derivatives against liver and ovarian cancers》, the research content is summarized as follows. An increasing number of artemisinin (ARS) and its derivatives have been reported for their potential therapeutic value of human cancer. However, their therapeutic potencies are limited owing to their poor pharmacokinetic profiles. Our previous studies showed that lead compound I originated from incorporating the pharmacophore of the approved chemotherapeutic agent melphalan into the basic skeleton of artemisinin with a succinic linker exhibited an excellent toxicity to human ovarian cancer cells and low cytotoxicity to normal cells. The mechanism studies demonstrated that it inhibited the growth and proliferation of ovarian cancer cells and resulted in S-phase arrest, apoptosis and inhibition of migration. Meanwhile, it exhibited excellent antitumor activities in animal models. Herein, further structure optimization for this lead compound I was performed and nineteen novel derivatives were designed and synthesized. Several compounds demonstrated powerful cytotoxic effects against human liver cancer and ovarian cancer cell lines, with their IC_50s below 0.86μM against Hep3B and A2780 cell lines, which are superior to that of I. Four compounds were selected to further evaluate their antitumor activities in in vitro and in vivo ovarian and liver cancer models; the results indicated that compound II exhibited the best therapeutic effect, not only effectively inhibiting the growth of 7404 xenograft and Huh7 xenograft, but also presenting a good dose-dependent inhibition toward the growth of A2780 xenograft. Overall, based on these pos. results, these novel chem. structures may provide a new inspiration for the discovery of novel antitumor agents originated from artemisinin scaffolds.

Zhu, Peiyu;Zhang, Jian;Yang, Yifei;Wang, Lixun;Zhou, Jinpei;Zhang, Huibin research published 《 Design, synthesis and biological evaluation of isoxazole-containing biphenyl derivatives as small-molecule inhibitors targeting the programmed cell death-1/ programmed cell death-ligand 1 immune checkpoint》, the research content is summarized as follows. Monoclonal antibodies targeting the programmed cell death-1/ programmed cell death-ligand 1 (PD-1/PD-L1) immune checkpoint have achieved enormous success in cancer immunotherapy. But the antibody-based immunotherapies carry a number of unavoidable deficiencies such as poor pharmacokinetic properties and immunogenicity. Small-mol. PD-1/PD-L1 inhibitors offer the superiority of complementarity with monoclonal antibodies and represent an appealing alternative. A novel series of isoxazole-containing biphenyl compounds were designed, synthesized and evaluated as PD-1/PD-L1 inhibitors in this paper. The structure-activity relationship of the novel synthesized compounds indicated that the ring-closure strategy of introducing isoxazole could be employed and the 3-cyanobenzyl group was significant for the inhibitory activity against the PD-1/PD-L1 protein-protein interactions. Mol. docking studies were performed to help understand the binding mode of the small-mol. inhibitor with the PD-L1 dimer. In particular, compound II-12 was a promising anti-PD-1/PD-L1 inhibitor with the IC₅₀ value of 23.0 nM, providing valuable information for future drug development.

A series of 6-substituted carbazole-based retinoic acid-related orphan receptor gamma-t (RORγt) modulators were discovered through 6-position modification guided by insights from the crystallog. profiles of the “short” inverse agonist 6. With the increase in the size of the 6-position substituents, the “short” inverse agonist 6 first reversed its function to agonists and then to “long” inverse agonists. The cocrystal structures of RORγt complexed with the representative “short” inverse agonist 6 (PDB: 6LOB), the agonist 7d (PDB: 6LOA) and the “long” inverse agonist 7h (PDB: 6LO9) were revealed by X-ray anal. However, minor differences were found in the binding modes of “short” inverse agonist 6 and “long” inverse agonist 7h. To further reveal the mol. mechanisms of different RORγt inverse agonists, we performed mol. dynamics simulations and found that “short” or “long” inverse agonists led to different behaviors of helixes H11, H11′, and H12 of RORγt. The “short” inverse agonist 6 destabilizes H11′ and dislocates H12, while the “long” inverse agonist 7h separates H11 and unwinds H12. The results indicate that the two types of inverse agonists may behave differently in downstream signaling, which may help identify novel inverse agonists with different regulatory mechanisms.

Zalesak, Frantisek;Kovac, Ondrej;Lachetova, Eliska;Stastna, Nikola;Pospisil, Jiri research published 《 Unified Approach to Benzo[d]thiazol-2-yl-Sulfonamides》, the research content is summarized as follows. In this paper, a unified approach to N-substituted and N,N-disubstituted benzothiazole (BT) sulfonamides I [R = n-Bu, cyclohexyl, Bn, furan-2-ylmethyl, etc.; R¹ = H, Me; RR¹ = -(CH₂)₅-, -(CH₂)₂CH(OH)(CH₂)₂], II, III (R² = propan-2-yl, Bn, oxiran-2-ylmethyl, etc.; RR² = -(CH₂)₆-) and IV (Ar = Ph, 3-fluorophenyl, 4-chlorophenyl, etc.) was reported. The approach to BT-sulfonamides I and II starts from simple com. available building blocks (benzo[d]thiazole-2-thiol and primary and secondary amines such as allylamine, benzylamine, piperidine, etc.) that are connected via (a) a S oxidation/S-N coupling approach, (b) a S-N coupling/S-oxidation sequence, or via (c) a S-oxidation/S-F bond formation/SuFEx approach. The labile N-H bond in N-monoalkylated BT-sulfonamides III (pKa (BTSO2N(H)Bn) = 3.34 ± 0.05) further allowed to develop a simple weak base-promoted N-alkylation method and a stereoselective microwave-promoted Fukuyama-Mitsunobu reaction. N-Alkyl-N-aryl BT-sulfonamides IV were accessed with the help of the Chan-Lam coupling reaction. Developed methods were further used in stereo and chemoselective transformations of podophyllotoxin and several amino alcs. such as 3-aminopropan-1-ol and 6-aminohexan-1-ol.

N-spirocyclic cations possess double-cyclic non-planar structure that exhibit the highest alkali stability among quaternary ammonium cations, however, the extremely rigidity usually causes fragile membranes and poor conductivity In this work, a rod-coil grafts design is proposed for N-spirocyclic anion exchange membranes (AEMs), in which microphase separation of the hydrophilic N-spirocyclic rod grafts is significantly improved by the hydrophobic aggregation of the flexible alkyl coil grafts with polysulfone backbone. Mol. dynamic simulations indicate that the coil grafts contribute to microphase separation but fill in free volume to reduce water reservoir, therefore the rod-coil grafts design provides a way to evaluate the effects of microphase separation and free volume on conductivity The increasing conductivity with the length of coil grafts suggests a greater contribution of good microphase separation to OH- conduction. With optimized n-octylamine hydrophobic coil graft length, the N-spirocyclic AEM exhibits toughness (elongation at break of about 28.7%) and high OH- conductivity (136.2 mS cm^-1 at 80°C), resulting in high power d. (850.1 mW cm^-2), which is far greater than that assemble with other N-spirocyclic AEMs, and also bring N-spirocyclic AEMs into the top level of the cycloaliphatic AEMs reported in literatures.

Zhang, Yuxia;Yang, Jiaxin;Meng, Tingting;Qin, Yajuan;Li, Tingyou;Fu, Junjie;Yin, Jian research published 《 Nitric oxide-donating and reactive oxygen species-responsive prochelators based on 8-hydroxyquinoline as anticancer agents》, the research content is summarized as follows. Metal ion chelators based on 8-hydroxyquinoline (8-HQ) have been widely explored for the treatment of many diseases. When aimed at being developed into potent anticancer agent, a largely unmet issue is how to avoid nonspecific chelation of metal ions by 8-HQ in normal cells or tissues. In the current work, a two-step strategy was employed to both enhance the anticancer activity of 8-HQ and improve its cancer cell specificity. Considering the well-known anticancer activity of nitric oxide (NO), NO donor furoxan was first connected to 8-HQ to construct HQ-NO conjugates. These conjugates were screened for their cytotoxicity, metal-binding ability, and NO-releasing efficiency. Selected conjugates were further modified with a ROS-responsive moiety to afford prochelators. Among all the target compounds, prodrug HQ-NO-11 was found to potently inhibit the proliferation of many cancer cells but not normal cells. The abilities of metal chelation and NO generation by HQ-NO-11 were confirmed by various methods and were demonstrated to be essential for the anticancer activity of HQ-NO-11. In vivo studies revealed that HQ-NO-11 inhibited the growth of SW1990 xenograft to a larger extent than 8-HQ. Our results showcase a general method for designing novel 8-HQ derivatives and shed light on obtaining more controllable metal chelators.

A series of pleuromutilin analogs containing substituted 1,2,3-triazole moieties I [R1 = Me, Ph, 3-fluorophenyl, etc.] and II [R2 = R3 = Me, cyclohexyl, etc.] were designed, synthesized and assessed for their in vitro antibacterial activity against Methicillin-resistant Staphylococcus aureus (MRSA). Initially, the in vitro antibacterial activities of these derivatives against 4 strains of S. aureus (MRSA ATCC 43300, ATCC 29213, AD3, and 144) were tested by the broth dilution method. Most of the synthesized pleuromutilin analogs displayed potent activities. Among them, compounds I [R1 = 2-methylphenyl, 2-nitrophenyl, 4-nitrophenyl] (MIC = 0.5∼1 μg/mL) showed the most effective antibacterial activity and their anti-MRSA activity were further studied by the time-killing kinetics approach. Binding mode investigations by surface plasmon resonance (SPR) with 50S ribosome revealed that the selected compounds all showed obvious affinity for 50S ribosome (K_D = 2.32 x 10^-8∼5.10 x 10^-5 M). Subsequently, the binding of compounds I [R1 = 2-methylphenyl, 4-nitrophenyl] to the 50S ribosome was further investigated by mol. modeling.
