The expanded polyglutamine-containing mutant huntingtin (mHTT) protein is implicated in neuronal degeneration of medium spiny neurons in Huntington′s disease (HD) for which multiple therapeutic approaches are currently being evaluated to eliminate or reduce mHTT. Development of effective and orthogonal biomarkers will ensure accurate assessment of the safety and efficacy of pharmacol. interventions. We have identified and optimized a class of ligands that bind to oligomerized/aggregated mHTT, which is a hallmark in the HD postmortem brain. These ligands are potentially useful imaging biomarkers for HD therapeutic development in both preclin. and clin. settings. We describe here the optimization of the benzo[4,5]imidazo[1,2-a]pyrimidine series that show selective binding to mHTT aggregates over Aβ- and/or tau-aggregates associated with Alzheimer′s disease pathol. Compound [¹¹C]-2 was selected as a clin. candidate based on its high free fraction in the brain, specific binding in the HD mouse model, and rapid brain uptake/washout in nonhuman primate positron emission tomog. imaging studies.

A catalytic method to prepare highly substituted 1,3-dienes from two different alkenes is described using a directed, palladium(II)-mediated C(alkenyl)-H activation strategy. The transformation exhibits broad scope across three synthetically useful substrate classes masked with suitable bidentate auxiliaries (4-pentenoic acids, allylic alcs., and bishomoallylic amines) and tolerates internal nonconjugated alkenes, which have traditionally been a challenging class of substrates in this type of chem. Catalytic turnover is enabled by either MnO₂ as the stoichiometric oxidant or co-catalytic Co(OAc)₂ and O₂ (1 atm). Exptl. and computational studies were performed to elucidate the preference for C(alkenyl)-H activation over other potential pathways. As part of this effort, a structurally unique alkenylpalladium(II) dimer was isolated and characterized.

Liu, Shengda;Yan, Tengfei;Sun, Jianxin;Li, Fei;Xu, Jiayun;Sun, Hongcheng;Yu, Shuangjiang;Liu, Junqiu research published 《 Biomimetic Cascade Polymer Nanoreactors for Starvation and Photodynamic Cancer Therapy》, the research content is summarized as follows. The selective disruption of nutritional supplements and the metabolic routes of cancer cells offer a promising opportunity for more efficient cancer therapeutics. Herein, a biomimetic cascade polymer nanoreactor (GOx/CAT-NC) was fabricated by encapsulating glucose oxidase (GOx) and catalase (CAT) in a porphyrin polymer nanocapsule for combined starvation and photodynamic anticancer therapy. Internalized by cancer cells, the GOx/CAT-NCs facilitate microenvironmental oxidation by catalyzing endogenous H₂O₂ to form O₂, thereby accelerating intracellular glucose catabolism and enhancing cytotoxic singlet oxygen (¹O₂) production with IR irradiation The GOx/CAT-NCs have demonstrated synergistic advantages in long-term starvation therapy and powerful photodynamic therapy (PDT) in cancer treatment, which inhibits tumor cells at more than twice the rate of starvation therapy alone. The biomimetic polymer nanoreactor will further contribute to the advancement of complementary modes of spatiotemporal control of cancer therapy.

Liu, Wei;Lavagnino, Marissa N.;Gould, Colin A.;Alcazar, Jesus;MacMillan, David W. C. research published 《 A biomimetic SH2 cross-coupling mechanism for quaternary sp³-carbon formation》, the research content is summarized as follows. Bimol. homolytic substitution (SH2) is an open-shell mechanism that is implicated across a host of biochem. alkylation pathways. Surprisingly, however, this radical substitution manifold has not been generally deployed as a design element in synthetic C-C bond formation. Authors found that the SH2 mechanism can be leveraged to enable a biomimetic sp3-sp3 cross-coupling platform that furnishes quaternary sp3-carbon centers, a long-standing challenge in organic mol. construction. This heteroselective radical-radical coupling uses the capacity of iron porphyrin to readily distinguish between the SH2 bond-forming roles of open-shell primary and tertiary carbons, combined with photocatalysis to generate both radical classes simultaneously from widely abundant functional groups. Mechanistic studies confirm the intermediacy of a primary alkyl-Fe(III) species prior to coupling and provide evidence for the SH2 displacement pathway in the critical quaternary sp3-carbon bond formation step.

Liu, Xianjun;Xiang, Mei-hao;Zhou, Wen-jing;Wang, Fenglin;Chu, Xia;Jiang, Jian-hui research published 《 Clicking of organelle-enriched probes for fluorogenic imaging of autophagic and endocytic fluxes》, the research content is summarized as follows. Autophagy and endocytosis are essential in regulating cellular homeostasis and cancer immunotherapeutic responses. Existing methods for autophagy and endocytosis imaging are susceptible to cellular micro-environmental changes, and direct fluorogenic visualization of their fluxes remains challenging. We develop a novel strategy via clicking of organelle-enriched probes (COP), which comprises a pair of trans-cyclooctenol (TCO) and tetrazine probes sep. enriched in lysosomes and mitochondria (in autophagy) or plasma membrane (in endocytosis). These paired probes are merged and boost a fluorogenic click reaction in response to autophagic or endocytic flux that ultimately fuses mitochondria or plasma membrane into lysosomes. We demonstrate that this strategy enables direct visualization of autophagic and endocytic fluxes, and confer insight into correlation of autophagic or endocytic flux to cell surface expression of immunotherapeutic targets such as MHC-I and PD-L1. The COP strategy provides a new paradigm for imaging autophagic and endocytic fluxes, and affords potential for improved cancer immunotherapy using autophagy or endocytosis inhibitors.

Liu, Xin;Wang, Jianchun;Dong, Guangbin research published 《 Modular Entry to Functionalized Tetrahydrobenzo[b]azepines via the Palladium/Norbornene Cooperative Catalysis Enabled by a C7-Modified Norbornene》, the research content is summarized as follows. Here, the authors report a straightforward method to synthesize THBAs (tetrahydrobenzo[b]azepines), e.g., I, directly from simple aryl iodides RI (R = 3-chlorophenyl, quinolin-6-yl, 4-(morpholinyl)-2-methylphenyl, etc.) via palladium/norbornene (Pd/NBE) cooperative catalysis. Capitalizing on an olefin-tethered electrophilic amine reagent, an ortho amination followed by 7-exo-trig Heck cyclization furnishes the seven-membered heterocycle. To overcome the difficulty with ortho-unsubstituted aryl iodide substrates, a unique C7-bromo-substituted NBE, II, to offer the desired reactivity and selectivity was discovered. In addition to THBAs, synthesis of other benzo-seven-membered ring compounds e.g., III, can also be promoted by II. Combined exptl. and computational studies show that the C7-bromo group in II plays an important and versatile role in this catalysis, including promoting β-carbon elimination, suppressing benzocyclobutene formation, and stabilizing reaction intermediates. The mechanistic insights gained could guide future catalyst design. The synthetic utility has been demonstrated in a streamlined synthesis of tolvaptan (IV) and forming diverse pharmaceutically relevant THBA derivatives Finally, a complementary and general catalytic condition to access C6-substituted THBAs from ortho-substituted aryl iodides has also been developed.
