Xia, Lei;Tian, Jia;Yue, Tao;Cao, Hongliang;Chu, Ju;Cai, Haibo;Zhang, Weian research published 《 Pillar[5]arene-Based Acid-Triggered Supramolecular Porphyrin Photosensitizer for Combating Bacterial Infections and Biofilm Dispersion》, the research content is summarized as follows. The treatment of pathogenic bacterial infection has long been the most serious threat to human life and attracted widespread attention. Herein, a supramol. photosensitizer platform based on carboxylatopillar[5]arene (CP5) and tetrafluorophenyl porphyrin functionalized with a quaternary ammonium group (TFPP-QA) for combating bacteria and dispersing biofilm via photodynamic treatment is constructed. By introducing the host macrocycle CP5 and host-guest interaction, the supramol. photosensitizer has great biocompatibility and acid responsiveness. On the one hand, the acid-triggered dissociation of TFPP-QA/CP5 could induce the porphyrin photosensitizer to target bacterial cells and disrupt the charge balance of bacterial membranes, enhance the permeability of the bacterial membrane. On the other hand, the TFPP-QA/CP5 antibacterial platform possesses superb reactive oxygen species (ROS) generation capability under light irradiation, leading to enhanced photodynamic antibacterial efficacy. The in vitro and in vivo studies show that the supramol. photosensitizers exhibit high antibacterial efficiency and biofilm dissipation effect under 660 nm light irradiation Therefore, it is anticipated that the rational design and integration of photosensitizers and quaternary ammonium compounds through the supramol. strategy would provide a promising prospect for clin. photodynamic antimicrobial therapy.

Wu, Bocheng;Payero, Benny;Taylor, Sydney;Oyelere, Adegboyega K. research published 《 Discovery of novel STAT3 DNA binding domain inhibitors》, the research content is summarized as follows. STAT3 is a pro-oncogenic transcription factor. Pyrimethamine (PYM) is a STAT3 inhibitor that suppresses the proliferation of some cancer cells through downregulation of STAT3 target proteins. We have used structure-based tools to design novel PYM-based compounds Intracellular target validation studies revealed that representative compounds 11b-d and 15a downregulate STAT3 downstream proteins and inhibit STAT3 DNA binding domain (DBD). Relative to PYM, a cohort of these compounds are >100-fold more cytotoxic to cancer cells with constitutively active (high pSTAT3) and basal (low pSTAT3) STAT3 signaling, suggesting that STAT3 DBD inhibition is deleterious to the proliferation of cancer cells with low and high pSTAT3 levels.

Wu, Fangrui;Nie, Shenyou;Yao, Yuan;Huo, Tong;Li, Xin;Wu, Xiaowei;Zhao, Jidong;Lin, Yi-Lun;Zhang, Yinjie;Mo, Qianxing;Song, Yongcheng research published 《 Small-molecule inhibitor of AF9/ENL-DOT1L/AF4/AFF4 interactions suppresses malignant gene expression and tumor growth》, the research content is summarized as follows. Chromosome translocations involving mixed lineage leukemia (MLL) gene cause acute leukemia with a poor prognosis. MLL is frequently fused with transcription cofactors AF4 (~35%), AF9 (25%) or its paralog ENL (10%). The AHD domain of AF9/ENL binds to AF4, its paralog AFF4, or histone-H3 lysine-79 (H3K79) methyltransferase DOT1L. Formation of AF9/ENL/AF4/AFF4-containing super elongation complexes (SEC) and the catalytic activity of DOT1L are essential for MLL-rearranged leukemia. Protein-protein interactions (PPI) between AF9/ENL and DOT1L/AF4/AFF4 are therefore a potential drug target. Compound I was identified to be a novel small-mol. inhibitor of the AF9/ENL-DOT1L/ AF4/AFF4 interaction with IC₅₀s of 0.9-3.5μM. Pharmacol. inhibition of the PPIs significantly reduced SEC and DOT1L-mediated H3K79 methylation in the leukemia cells. Gene profiling shows compound I significantly suppressed the gene signatures related to onco-MLL, DOT1L, HoxA9 and Myc. It selectively inhibited proliferation of onco-MLL- or Myc-driven cancer cells and induced cell differentiation and apoptosis. Compound I exhibited strong antitumor activity in a mouse model of MLL-rearranged leukemia. The AF9/ENL-DOT1L/AF4/AFF4 interactions are validated to be an anticancer target and compound I is a useful in vivo probe for biol. studies as well as a pharmacol. lead for further drug development.

Wang, Zongqiang;Forelli, Nicholas;Hernandez, Yozen;Ternei, Melinda;Brady, Sean F. research published 《 Lapcin, a potent dual topoisomerase I/II inhibitor discovered by soil metagenome guided total chemical synthesis》, the research content is summarized as follows. In natural product discovery programs, the power of synthetic chem. is often leveraged for the total synthesis and diversification of characterized metabolites. The synthesis of structures that are bioinformatically predicted to arise from uncharacterized biosynthetic gene clusters (BGCs) provides a means for synthetic chem. to enter this process at an early stage. The recent identification of non-ribosomal peptides (NRPs) containing multiple ρ-aminobenzoic acids (PABAs) led us to search soil metagenomes for BGCs that polymerize PABA. Here, we use PABA-specific adenylation-domain sequences to guide the cloning of the lap BGC directly from soil. This BGC was predicted to encode a unique N-acylated PABA and thiazole containing structure. Chem. synthesis of this structure gave lapcin, a dual topoisomerase I/II inhibitor with nM to pM IC₅₀s against diverse cancer cell lines. The discovery of lapcin highlights the power of coupling metagenomics, bioinformatics and total chem. synthesis to unlock the biosynthetic potential contained in even complex uncharacterized BGCs.

The mechanochem. reactions of a series of dendrimers with a mechanochromic core were systematically investigated, and drastic enhancement of their reactivity was observed after their surface functionalization. We recently reported the quant. and qual. mechano-responsive behavior characteristic of a radical-type mechanophore for mechanochromic dendrimers (MDs) with defined structures in the bulk. In the present study, we systematically investigated the mechanochem. response of a series of dendrimers with different functional groups on their surfaces by mech. grinding in the bulk. Effective activation of the mechanochromic core was achieved in higher-generation MDs with hydrogen-bonding amide groups on their surfaces. A comparison of the degree of activation of the MDs with that of linear analogs revealed that the chain overlap, mol. size, and polarity affect the efficiency of the transmission of the grinding force to the mechanochromic core.

To discover new nematicides I (n = 1, 2, 3; R = Et, iso-Pr, 4-nitrobenzyl, etc.) a series of novel amide derivatives containing an imidazo[1,2-a]pyridine moeity I were designed and synthesized. Among the title compounds, compounds I (n = 1; R = Pr and n = 3; R = n-decyl (III)) exhibited good nematicidal activities against Aphelenchoides besseyi (rice white-tip nematode), with LC₅₀ values against of 27.3 and 35.9 mg/L, resp., which were superior to that of fosthiazate (45.4 mg/L).

Furthermore, the lead compound III could also antagonize the activation of STAT3 induced by HDACs inhibition in some breast cancer cells, which further reduced the level of pro-survive proteins in tumor cells and enhanced anti-tumor activity regulated by STAT3 signaling in vivo. Overall, findings demonstrated that the novel compound III might be a HDACs inhibitor candidate, which could be used as promising chemotherapeutic agent for breast cancer.
