A new, simple, and rapid photochemical reaction of o-phthalaldehyde with C-60 has been disclosed. This reaction afforded exclusively the unanticipated C-60-phthalide derivative 11 in good yield. The formation of this product is consistent with the intervention of a key free-radical intermediate -a benzylic radical- in the course of the reaction. The structure of 11 has been determined by the combined use of experimental and theoretical NMR studies. In the course of this study we further disclosed a new mode of radical reactivity of C-60 with a series of substituted phthalides (2, 15-17) catalyzed by tetrabutylammonium decatungstate.

Name: Isobenzofuran-1(3H)-one. I found the field of Immunology; Pharmacology & Pharmacy very interesting. Saw the article Phthalide derivative CD21 ameliorates ischemic brain injury in a mouse model of global cerebral ischemia: involvement of inhibition of NLRP3 published in 2020, Reprint Addresses Du, JR (corresponding author), Sichuan Univ, Dept Pharmacol, Chengdu 610041, Peoples R China..

The activation of NLRP3 inflammasome is closely related to ischemic brain injury and inhibition of NLRP3 inflammasome activation may be a new therapeutic strategy for ischemic stroke. Our previous studies showed that ligustilide (LIG) had a dose-dependent neuroprotective effect on various models of cerebral ischemia and dementia in vivo and in vitro. CD21, a kind of phthalide derivative, was modified from LIG. In this study, we established a global cerebral ischemia-reperfusion model in mice by bilateral common carotid artery ligation (2VO), and explored the neuroprotective effect of CD21 and its anti-inflammatory mechanism on cerebral ischemia mice. CD21 significantly improved weight loss, neurobehavioral deficits and neurons loss in hippocampal CA1 and caudate putamen (CPu) subregions, which were induced by 2VO in mice. CD21 significantly inhibited the overactivation of astrocyte and microglia, and decreased the mRNA level of IL-6, TNF-alpha and IL-1 beta. Moreover, CD21 significantly inhibited the activation of TLR4/NF-kappa B signaling pathway mediated by HMGB1 and NLRP3/ASC/Caspase-1 signaling pathway mediated by Cathepsin B, thus inhibiting the activation of NLRP3 inflammasome. Our results demonstrated that CD21 may exert a neuroprotection by inhibiting NLRP3 inflammasome activation after cerebral ischemia. These findings provide a new strategy for the treatment of ischemic stroke.

For the oxide-based photocatalysts, polyoxylic acid modification can affect their adsorption/desorption properties and further regulate photocatalytic reaction pathway, which is crucial for enhancing photocatalytic activity and selectivity. Herein, phosphoric acid modified TiO2 was synthesized by a facile impregnation-calcination method for photocatalytic degradation of gaseous o-xylene. According to FTIR, XPS, and EDS analysis, phosphoric acid was anchored on the surface of TiO2 successfully. The surface P atomic percentages for PT1 was 2.45%. The as-prepared phosphoric acid modified TiO2 (PTx) had a photocatalytic performance superior to that of commercial TiO2 and unmodified TiO2 (PT0), with increasing by 2.2 times at most. Interestingly, the phosphoric acid molecules strongly adsorbed on anatase TiO2 surface by forming H-O-2C and =O-Ti-5C chemical bonds according to the first principle calculations, which changed TiO2 surface properties (specific surface area and surface negative electrostatic field) and further improved adsorption and charge carrier separation and transfer, thus improving the photocatalytic activity. Additionally, according to the intermediates results, the relative abundance of intermediates shows obvious difference. Acetone was detected as the most abundant intermediates during o-xylene degradation for PT0, whereas that was o-methyl benzaldehyde for PT1, which could be ascribed to the difference of surface adsorption configuration of o-xylene. According to the temperature-programmed desorption (TPD) results, the surface modified by phosphoric acid could change the o-xylene adsorption configuration to favor its methyl oxidation (standing configuration), whereas the unmodified surface could be more favorable to the benzene ring-open reaction (lying configuration). This work will deepen the understanding of the relevance of surface modification and surface photocatalytic reaction, which also provides a feasible strategy to improve photocatalytic selectivity.

The Pd-catalyzed three-component coupling polycondensation of diiodoarenes, nonconjugated dienes, and carbonucleophiles afforded poly(arylene alkenylene)s with moderate molecular weight in good yield. The reaction involves Mizoroki-Heck coupling, olefin migration via chain walking, and addition of the carbonucleophile to the resulting pi-allylpalladium species. The polymerization with a slight excess of nucleophile with respect to diiodoarene also proceeded to give the polymer without significant decrease in molecular weight in spite of the nonstoichiometric mixture of the monomers. The Pd-catalyzed three-component coupling polycondensation of diiodoarenes, nonconjugated dienes, and diimide also proceeded. The base used in the reaction is critical for yield and molecular weight of the product. The reaction using NaHCO3 afforded the product with low solubility, which can be explained by the high molecular weight of the polymer and/or the strong interaction of the electron donating dimethoxyphenylene groups and electron accepting diimide groups in the polymer.

Microglia can be activated to become the classic phenotype (M1) or alternative phenotype (M2), which play an important role in regulating neuroinflammatory response and tissue repair after ischemic stroke. CD21, a novel phthalide derivative, is a potential neuroprotectant against ischemic brain injury. The present study further investigated the effects of CD21 on post-ischemic microglial polarization and the underlying mechanisms. Transient middle cerebral artery occlusion (tMCAO) was used as a mouse model of ischemic stroke, while BV2 cells stimulated with conditioned medium collected from oxygen-glucose deprivation-treated HT22 cells were used in in vitro ischemic studies. The current results showed that CD21 dose-dependently and significantly improved neurological outcomes in tMCAO mice. Biochemical analyses revealed that CD21 decreased the expression of M1 phenotype markers (CD86, interleukin-1 beta and inducible nitric oxide synthase) and increased the expression of M2 phenotype markers (CD206, interleukin-10 and YM1/2) in both ischemic brain tissues and BV2 cells. Meanwhile, CD21 decreased the production of proinflammatory cytokines (interleukin-1 beta, interleukin-6 and tumor necrosis factor-alpha), promoted the release of the antiinflammatory cytokine (interleukin-10), and enhanced the phosphorylation of adenosine 5′-monophosphate-activated protein kinase (AMPK) in ischemic brain tissue and BV2 cells. Furthermore, the AMPK inhibitor (compound C) reversed these effects of CD21 in BV2 cells. These findings indicate that CD21 alleviates post-ischemic neuroinflammation through induction of microglial M2 polarization that is at least in part medicated by AMPK activation, suggesting that CD21 may be a promising candidate for protecting against ischemic brain injury.

Atherosclerosis is initiated by the local inflammation response to lipid deposition, and the most commonly administered antiatherogenic drugs are statins. Based on traditional Chinese medicine (TCM) evidence, we aimed to find effective therapeutic agents other than statins. A TCM, Suxiao Jiuxin Pill (SX), has been widely used in curing cardiovascular diseases for thirty years. In this paper, a combination of pharmacologic studies and RNA-Seq transcriptomics were employed to explore the pharmacodynamic advantages of SX over atorvastatin in the ApoE(-/-) mouse. 113 differentially expressed genes that were modulated by SX to a greater degree than atorvastatin were primarily involved in immunomodulation. The expression of BTK, AKT1, c-jun and CD137 was effectively regulated by SX with better effect than atorvastatin. Then a dual-luciferase reporter assay for NF-kappa B inhibition was applied to identify active components in SX. As a result, Senkyunolide A (Sen A) and Ligustilide (Lig), the key immunomodulatory ingredients in SX, were found to inhibit the expression of CD137 which is a diagnostic biomarker in atherosclerosis. It was further confirmed that Lig effectively suppressed the expression of AP-1 and NF-kappa B and the phosphorylation of AKT. Therefore, Lig achieved its CD137 inhibition through suppressing the expression of AP-1 and AKT/NF-kappa B signaling pathway, which partly explains the immunomodulation of SX in atherosclerosis. Above all, phthalides may be the primary components of SX improving immune and inflammation response in atherosclerosis.

Phthalides as the crucial core skeletons are found extensively in natural products and biological active molecules. Herein we disclose an asymmetric allylation of 3-hydroxyisoben-zofuran-1(3H)-ones with boron allylation reagents to construct chiral phthalide derivatives. The simple Bi(OAc)(3)/chiral phosphoric acid catalytic system proves to be efficient in this method, delivering the desired chiral 3-allylisobenzofuran-1(3H)-ones in good yields (up to 99%) and high enantioselectivities (up to 99.5:0.5 e.r.) under mild conditions. The large-scale reaction and diverse transformations of products to various scaffolds with potential biological activities render it more attractive. Moreover, the mechanism was preliminarily explored by control reactions, mass spectrometry, deuterium experiment, and DFT calculations.

Aims: Partial PPAR gamma agonists attracted substantially heightened interest as safer thiazolidinediones alternatives. On the other hand, Wnt/beta-catenin antagonists have been highlighted as promising strategy for type 2 diabetes management via up-regulating PPAR gamma gene expression. We aimed at synthesizing novel partial PPAR gamma agonists with beta-catenin inhibitory activity which could enhance insulin sensitivity and avoid the side effects of full PPAR gamma agonists. Main methods: We synthesized novel series of alpha-phthlimido-o-toluoyl-2-aminothiazoles hybrids for evaluating their antidiabetic activity and discovering its mechanistic pathway. We assessed effect of the new hybrids on PPAR gamma activation using a luciferase reporter assay system. Moreover, intracellular triglyceride levels, gene levels of c/EBP alpha, PPAR gamma and PPAR gamma targets including GLUT4, adiponectin, aP2 were measured in 3T3-L1 cells. Uptake of 2-DOG together with PPAR gamma and beta-catenin protein levels were evaluated in 3T3-L1cells. In addition, molecular docking studies with PPAR gamma LBD, physicochemical properties and structure activity relationship of the novel hybrids were also studied. Key findings: Three of the synthesized hybrids showed partial PPAR gamma agonistic activity and distinct PPAR gamma binding pattern. These compounds modulated PPAR gamma gene expression and PPAR gamma target genes; and increased glucose uptake in 3T3-L1 and slightly induced adipogenesis compared to rosiglitazone. Moreover, these compounds reduced beta-catenin protein level which reflected in increased both PPAR gamma gene and protein levels that leads to improved insulin sensitivity and increased GLUT4 and adiponectin gene expression. Significance: Our synthesized compounds act as novel partial PPAR gamma agonists and beta-catenin inhibitors that have potent insulin sensitizing activity and mitigate the lipogenic side effects of TZDs.
