Abstract
2-Aminobenzothiazoles are widely used in the fields of pharmaceuticals and pesticides. Herein, we report a metal-free protocol for the preparation of 2-aminobenzothiazoles by a covalent organic framework (COF) catalyzed tandem reaction. In the presence of catalytic amount of phenanthroline-decorated COF (Phen-COF), a variety of 2-aminobenzothiazoles are obtained in excellent yields by the cross-coupling of 2-iodoanilines with isothiocyanates at room temperature in water. In addition, the COF-catalyst is very stable and can be reused at least seven times without loss of its catalytic activity.

Abstract
Covalent organic frameworks (COFs) have recently drawn intense attention due to their potential applications in photocatalysis. Herein, we report a multifunctional COF which consists of triphenylamine (TPA) and 2,2'-bipyridine (2, 2'-bipy) entities. The obtained TAPA-BPy-COF is a heterogeneous photocatalyst and can efficiently catalyze the oxidative coupling of thiols to disulfides. In addition, TAPA-BPy-COF can be further metalated by Pd(II) via 2,2'-bipy-metal coordination. The generated Pd@TAPA-BPy-COF can highly promote photocatalytic synthesis of 3-cyanopyridines via cascade addition/cyclization of arylboronic acids with γ-ketodinitriles in heterogeneous way. This work has demonstrated the way for the rational design and preparation of more efficient photoactive COFs for photocatalysis.

Abstract
Radiotherapy is inevitably accompanied by some degree of radiation resistance, which leads to local recurrence and even therapeutic failure. To overcome this limitation, herein, we report the room-temperature synthesis of an iodine- and ferrocene-loaded covalent organic framework (COF) nanozyme, termed TADI-COF-Fc, for the enhancement of radiotherapeutic efficacy in the treatment of radioresistant esophageal cancer. The iodine atoms on the COF framework not only exerted a direct effect on radiotherapy, increasing its efficacy by increasing X-ray absorption, but also promoted the radiolysis of water, which increased the production of reactive oxygen species (ROS). In addition, the ferrocene surface decoration disrupted redox homeostasis by increasing the levels of hydroxyl and lipid peroxide radicals and depleting intracellular antioxidants. Both in vitro and in vivo experiments substantiated the excellent radiotherapeutic response of TADI-COF-Fc. This study demonstrates the potential of COF-based multinanozymes as radiosensitizers and suggests a possible treatment integration strategy for combination oncotherapy.

Abstract
Multicomponent reactions (MCRs), as a powerful one-pot combinatorial synthesis tool, have been recently applied to the synthesis of covalent organic frameworks (COFs). Compared with the thermally driven MCRs, the photocatalytic MCR-based COF synthesis has not yet been investigated. Herein, we first report the construction of COFs by a photocatalytic multicomponent reaction. Upon visible-light irradiation, a series of COFs with excellent crystallinity, stability, and permanent porosity are successfully synthesized via photoredox-catalyzed multicomponent Petasis reaction under ambient conditions. Additionally, the obtained Cy-N3-COF exhibits excellent photoactivity and recyclability for the visible-light-driven oxidative hydroxylation of arylboronic acids. The concept of photocatalytic multicomponent polymerization not only enriches the methodology for COF synthesis but also opens a new avenue for the construction of COFs that might not be possible with the existing synthetic methods based on thermally driven MCRs.

Abstract
Stimulus-responsive biodegradable nanocarriers with tumor-selective targeted drug delivery are critical for cancer therapy. Herein, we report for the first time a redox-responsive disulfide-linked porphyrin covalent organic framework (COF) that can be nanocrystallized by glutathione (GSH)-triggered biodegradation. After loading 5-fluorouracil (5-Fu), the generated nanoscale COF-based multifunctional nanoagent can be further effectively dissociated by endogenous GSH in tumor cells, releasing 5-Fu efficiently to achieve selective chemotherapy on tumor cells. Together with the GSH depletion-enhanced photodynamic therapy (PDT), an ideal synergistic tumor therapy for MCF-7 breast cancer via ferroptosis is achieved. In this research, the therapeutic efficacy was significantly improved in terms of enhanced combined anti-tumor efficiency and reduced side effects by responding to significant abnormalities such as high concentrations of GSH in the tumor microenvironment (TME).

Abstract
Although natural sunlight-mediated photocatalysis is a clean, efficient, and green approach to access organic products, its application in the synthesis of covalent organic frameworks (COFs), however, is still unprecedented. Herein, we first report the sunlight photocatalytic synthesis of COF under ambient conditions. Furthermore, this "window ledge" reaction generated benzoxazole-linked COF is stable and can be applied as a reusable photocatalyst to highly promote visible-light-driven aerobic oxidation of sulfides to sulfoxides. These results not only enrich the COF synthetic methodology but also open a new route to access COFs in a green and sustainable way.

Abstract
Small interfering RNA (siRNA)-mediated gene silencing is a promising therapeutic approach. Herein, we report the ambient synthesis of a positively charged iminium-linked covalent organic framework by a three-component one-pot reaction. Through anion exchange and siRNA adsorption, the resulting multifunctional siRNA@ABMBP-COF, which possesses both the HK2 inhibitor 3-bromopyruvate and SLC7A11 siRNA, exhibits powerful synergistic antitumor activity against fibrosarcoma via the ferroptosis and apoptosis pathways.

Abstract
Providing safe and clean domestic water for people is currently one of the greatest worldwide issues. In this context, heavy metal ions and pathogenic microbes are the two major factors in water pollution. The conventional water treatment methods, however, are generally high-energy and high-resource consumptive. Herein, we report, the first of its kind, the room-temperature synthesis of α-aminophosphonate-linked COFs via three-component one-pot in situ Kabachnik-Fields reaction (KF-3CR). Due to the coexistent bioactive α-aminophosphonate and photosensitive porphyrin, the obtained APCOF-1 exhibits highly efficient solar-powered bactericidal and heavy metal ion removal abilities, which allows it to be a promising COF-based multifunctional material for water treatment in an energy- and resource-saving way. Specifically, by incorporating APCOF-1 (up to 50 wt%) with eco-friendly and low-cost chitosan, an APCOF-1 @chitosan aerogel-based helical setup is fabricated via a facile templated freeze-drying approach and it can be a continuous flow-through water purifier model to achieve scaled-up water treatment through adsorptive removal of heavy metal ions and sunlight-driven sterilization. We believe that this research not only can significantly enrich the synthetic methodology of COFs, but also will hopefully bring COFs one step closer to the practical application.

Abstract
A general and efficient organocatalytic asymmetric polymerization approach for the synthesis of chiral covalent organic frameworks (CCOFs) has been developed. With a chiral 2-methylpyrrolidine catalyst, a series of tris(N-salicylideneamine)-derived β-ketoenamine-CCOFs are directly constructed from prochiral aldehyde- and primary amine-monomers. The adopted aminocatalytic asymmetric Schiff-base condensation herein is performed under ambient conditions with clear green synthetic advantages over the conventional acid-catalysed solvothermal methods. The obtained β-ketoenamine-CCOFs can be further metalated by a solid-state coordination approach, and the resulting CuII @CCOFs can highly promote an asymmetric A3 -coupling reaction. Specifically, a CuII @CCOF@chitosan aerogel was fabricated as a highly efficient fixed-bed model reactor for scaled-up catalysis. The concept of aminocatalytic asymmetric polymerization might open a new way for constructing the CCOFs via asymmetric organocatalysis.

Abstract
Although chiral covalent organic frameworks (CCOFs) presence grows in thermal asymmetric catalysis, their application in equally important asymmetric photocatalysis has yet to begin. Herein, we first report a propargylamine-linked and quaternary ammonium bromide decorated porphyrin-CCOF which can highly promote visible-light-driven enantioselective photooxidation of sulfides to sulfoxides in water and in air. This methodology has also been applied to the synthesis of (R)-modafinil, a wakefulness-promoting medication used for the treatment of excessive sleepiness. This research might open a new way for the application of CCOFs in asymmetric photocatalysis.

Abstract
We report the construction of a porphyrin and imidazolium-ionic liquid (IL)-decorated and quinoline-linked covalent organic framework (COF, abbreviated as COF-P1-1) via a three-component one-pot Povarov reaction. After post-synthetic metallization of COF-P1-1 with Co(II) ions, the metallized COF-PI-2 is generated. COF-PI-2 is chemically stable and displays highly selective CO2 adsorption and good visible-light-induced photothermal conversion ability (ΔT = 26 °C). Furthermore, the coexistence of Co(II)-porphyrin and imidazolium-IL within COF-PI-2 has guaranteed its highly efficient activity for CO2 cycloaddition. Of note, the needed thermal energy for the reactions is derived from the photothermal conversion of the Co(II)-porphyrin COF upon visible-light irradiation. More importantly, the CO2 cycloaddition herein is a "window ledge" reaction, and it can proceed smoothly upon natural sunlight irradiation. In addition, a scaled-up CO2 cycloaddition can be readily achieved using a COF-PI-2@chitosan aerogel-based fixed-bed model reactor. Our research provides a new avenue for COF-based greenhouse gas disposal in an eco-friendly and energy- and source-saving way.

Abstract
Herein we describe a simple fluorescence quenching method for the selective recognition and determination of the amino acid phenylalanine (Phe). The use of 1H NMR spectroscopy revealed that the alkaloid palmatine (PAL) can encapsulated partially into the cavity of cucurbit[7]uril (Q[7]) in aqueous solution to form a stable 1:1 host-guest inclusion complex. This host-guest complex exhibits fluorescence of moderate intensity. Interestingly, the addition of the Phe results in a dramatic quenching of the fluorescence intensity associated with the inclusion complex. By contrast, the addition of other natural amino acids resulted in no change in the fluorescence. Based on the linear relationship between the fluorescence intensity and the concentration of Phe, the detection of the concentration of Phe in aqueous solution is facile. Thus, a new fluorescence quenching method for the recognition and determination of the Phe has established herein.

Abstract
Synergistic phototherapy combining photodynamic therapy (PDT) and photothermal therapy (PTT) based on near-infrared (NIR) dyes using a single light source offers the opportunity to treat diseases at deep locations. In this study, we reported human serum albumin (HSA)-involving tetra(butylamino)phthalocyanine (Pc)-based nanomaterials of HSA-α-Pc and HSA-β-Pc as highly efficient dual-phototherapy agents, namely 1(4),8(11),15(18),22(25)-tetra(butylamino)phthalocyanine (α-Pc) and 2(3),9(10),16(17),23(24)-tetra(butylamino)phthalocyanine (β-Pc). Both HSA-α-Pc and HSA-β-Pc showed excellent photothermal effects under a single NIR (808 nm) laser irradiation due to the S1 fluorescence emission quenching of Pcs. Compared to HSA-β-Pc, HSA-α-Pc exhibited better singlet oxygen generation ability and its highly efficient PDT/PTT dual-phototherapy was also well evidenced via in vitro and vivo experiments under a single 808 nm laser irradiation. Overall, this approach would be viable for the fabrication of more new Pc-based metal-free nano agents for PDT/PTT synergistic phototherapy upon a single NIR light source. Two new HSA-involved tetra(butylamino)phthalocyanine composite nanoparticles, as highly efficient dual-phototherapy agents upon a single NIR laser irradiation, were reported.![]()

Abstract
As one of the noninvasive cancer treatments, photothermal therapy (PTT) has drawn intense attention recently. In this context, an important task is to explore novel and versatile nanoscale photothermal agents (PTAs), especially those with strong NIR-II light absorption, high photothermal conversion efficiency, good photostability and biocompatibility. Phthalocyanines (Pcs), as the second-generation photosensitizers, are a promising class of candidates for PTT due to their strong NIR absorption and high photothermal conversion efficiency. However, the poor water solubility severely limited their application as PTAs in tumor treatment. Herein, we report a molecular phosphorus phthalocyanine (P-Pc)-based nanoagent via incorporation of human serum albumin (HSA) under mild conditions. The obtained nanoscale P-Pc-HSA possesses excellent photothermal conversion efficiency (64.7%) upon 1064 nm light irradiation, furthermore, it can be a highly efficient NIR-II antitumor nanoagent via photothermal treatment (PTT), which is fully evidenced by the in vitro and in vivo experiments. A molecular phosphorus phthalocyanine (P-Pc)-based nanoagent P-Pc-HSA, which can be a highly efficient NIR-II antitumor agent, is reported.![]()

Abstract
The first molecular material-based PTA for the NIR-II photothermal therapy with high PCE of 58.3% was reported. The Zn4-H2Pc/DP NPs reveal good biocompatibility and notable tumor ablation ability in 1064 nm.
Photothermal therapy in the second near-infrared window (NIR-II, 1000–1700 nm) exhibits a significant advantage over the first near-infrared window (NIR-I, 650–950 nm) in terms of both maximum permissible exposure (MPE) and penetration depth. However, the thus far reported NIR-II photothermal agents (PTAs) have been focused just on inorganic semiconducting and organic polymeric semiconducting nanoparticles. Herein a novel cruciform phthalocyanine pentad was designed, synthesized, and characterized for the first time. The water-soluble nanoparticles (Zn4–H2Pc/DP NPs) assembled from this single molecular material with the help of DSPE–PEG2000–OCH3 exhibit characteristic absorption in the NIR-II region at 1064 nm with a large extinction coefficient of 52 L g–1 cm–1, high photothermal conversion efficiency of 58.3%, and intense photoacoustic signal. Moreover, both in vitro and in vivo studies reveal the good biocompatibility and notable tumor ablation ability of Zn4–H2Pc/DP NPs under 1064 nm laser irradiation. Theoretical density functional theory calculations interpret the two-dimensional compressional wave energy-dissipation pathway over the broad saddle curved framework of the cruciform conjugated phthalocyanine pentad, rationalizing the efficient photothermal properties of corresponding Zn4–H2Pc/DP NPs in the NIR-II window.

Abstract
We report an allyl-decorated and hydrazine-connected covalent organic framework (COF-AO, 1), which could support Pd nanoparticles (Pd NPs) to generate Pd@COF-AO, 2. The incorporation of 2 with thiol-functionalized polysiloxane (termed as PSI-SH) via thiol-ene click reaction provided the stand-alone and elastic membrane (3). The obtained COF-involved and Pd NP-loaded covalently linked membrane of 3 is robust, permanently porous, uniform, processable, and water permeable. Moreover, it can be used to construct highly efficient membrane-based microreactor for continuous-flow operation to catalyze chlorobenzenes (CBs) dechlorination in water at room temperature. The provided approach herein allows the processability and practical application of the powdered COF materials to be feasible.

Abstract
Nanocrystallization of organic molecular photosensitizers (PSs) by means of NMOF platforms has been demonstrated to be a promising approach to build up highly efficient PDT therapeutics. We report herein a new UiO-66 type of NMOF-based PS (UiO-66-TPP-SH), which is generated from UiO-66 NMOF and S-ethylthiol ester monosubstituted metal free porphyrin (TPP-SH) via a facile postsynthetic approach under mild conditions. The obtained NMOF (size less than 150 nm) with surface-decorated porphyrinic PS can not only retain MOF crystallinity, structural feature, and size, but also exhibit highly efficient singlet oxygen generation. Compared to the interior-located porphyrinic NMOF, UiO-66-TPP-SH shows significantly higher photodynamic activity and more efficient PDT tumor treatment.

Abstract
Interactions between inverted cucurbit[7]uril (iQ[7]) and essential amino acids have been studied at pH = 7.0 by 1H NMR spectroscopy, electronic absorption spectroscopy, isothermal titration calorimetry, and mass spectrometry. The interactions can be divided into three binding types at pH = 7.0. Experimental results from the present study showed that the host displays a strong binding to the aromatic amino acids, Trp and Phe, and the guests of Lys, Arg, and His lie outside the cavity portal of the host. Meanwhile, the alkyl moieties of the guests Met, Leu, and Ile were accommodated within the cavity of iQ[7], but there was no significant interaction between iQ[7] and Thr or Val. The complexation behavior of iQ[7] with essential amino acids was explored at pH = 3, and the binding of Lys, Arg, and His revealed an unexpected behavior, with their side chains located in the cavity of iQ[7], whereas those of the aromatic Trp and Phe were deeper within the iQ[7] cavity. The alkyl side chains of the guests Met, Leu, Ile, Thr, and Val were also located inside the iQ[7] cavity and formed the host-guest complexes.

Abstract
A new composite Au@Cu(II)-MOF catalyst has been synthesized via solution impregnation and full characterized by HRTEM, SEM-EDS, XRD, gas adsorption-desorption, XPS, and ICP analysis. It has been shown here that the Cu(II)-framework can be a useful platform to stabilize and support gold nanoparticles (Au NPs). The obtained Au@Cu(II)-MOF exhibits a bifunctional catalytic behavior and is able to promote selective aerobic benzyl alcohol oxidation-Knoevenagel condensation in a stepwise way.

Abstract
Splicing of certain pre-mRNA introns is dependent on an enhancer element, which is typically purine-rich. It is generally thought that enhancers increase the use of suboptimal splicing signals, and one specific proposal is that enhancers stabilize binding of U2AF65 to weak polypyrimidine (Py) tracts. Here, we test this model using an IgM pre-mRNA substrate, which contains a well-characterized enhancer. Although the enhancer was required for in vitro splicing, we found it had no effect on U2AF65 binding. Unexpectedly, replacement of the natural IgM Py tract, branchpoint, and 5' splice site with consensus splicing signals did not circumvent the enhancer requirement. These observations led us to identify a novel regulatory element within the IgM M2 exon that acts as a splicing inhibitor; removal of the inhibitor enabled splicing to occur in the absence of the enhancer. The IgM M2 splicing inhibitor is evolutionarily conserved, can inhibit the activity of an unrelated, constitutively spliced pre-mRNA, and acts by repressing splicing complex assembly. Interestingly, the inhibitor itself forms an ATP-dependent complex that contains U2 snRNP. We conclude that splicing of IgM exons M1 and M2 is directed by two juxtaposed regulatory elements-an enhancer and an inhibitor-and that a primary function of the enhancer is to counteract the inhibitor.

Abstract
The mouse glycinamide ribonucleotide formyltransferase (GART) locus is known to produce two functional proteins, one by recognition and use of an intronic polyadenylation site and the other by downstream splicing. We now report a similar intronic polyadenylation mechanism for the human GART locus. The human GART gene has two potential polyadenylation signals within the identically located intron as that involved in intronic polyadenylation in the mouse gene. Each of the potential polyadenylation signals in the human gene was followed by an extensive polyT rich tract, but only the downstream signal was preceded by a GT tract. Only the downstream signal was utilized. The polyT rich tract which followed the functional polyadenylation site in the human GART gene was virtually identical in sequence to a similarly placed region in the mouse gene. An exact inverted complement to the polyT rich stretch following the active polyadenylation signal was found in the upstream intron of the human gene, suggesting that a hairpin loop may be involved in this intronic polyadenylation.

Abstract
A single mouse genomic locus encodes proteins catalyzing three steps of purine synthesis, glycinamide ribonucleotide synthetase (GARS), aminoimidazole ribonucleotide synthetase (AIRS), and glycinamide ribonucleotide formyltransferase (GART). This gene has 22 exons and spans 28 kilobases. The existence of a second genetic locus and closely related pseudogenes was ruled out by Southern analysis. Mouse tissues express two related classes of messages encoded by this single locus: a trifunctional GARS-AIRS-GART mRNA and a monofunctional GARS mRNA. These transcripts used the same set of multiple transcriptional start sites, and both used the same first 10 exons. CCAAT and TATA elements were not found for this locus. Exon 11, which represented the last coding sequence of the GARS domain, was differentially utilized for the two messages. The trifunctional mRNA was generated by splicing exon 11 to exon 12, the first coding sequence for the AIRS domain with subsequent use of a polyadenylation signal at the end of exon 22. Genomic sequence corresponding to the 3'-UTR of the monofunctional GARS mRNA was contiguous with exon 11, so that the smaller message arose from the recognition of one of the multiple polyadenylation signals present within the intron between exons 11 and 12. Hence, polyadenylation of the primary transcript at a position corresponding to an intron of the genomic locus was responsible for the generation of the monofunctional GARS class of mRNAs. This utilization of an intronic polyadenylation site without alternative exon usage is comparable to the mechanism whereby both secreted and membrane-bound forms of the immunoglobulin mu heavy chain are made from a single genetic locus.

Abstract
Three of the enzymatic activities of de novo purine synthesis, glycinamide ribonucleotide synthetase (GARS), aminoimidazole ribonucleotide synthetase (AIRS) and glycinamide ribonucleotide formyltransferase (GART), can be catalyzed by a single 110-kDa protein in mouse cells. Western blots using a polyclonal antibody (Ab) to this protein identified two species, the trifunctional 110-kDa protein and a 50-kDa cytosolic protein with GARS, but not GART activity. We used Ab and, subsequently, oligodeoxyribonucleotide screens to isolate cDNAs corresponding to these two proteins from mouse T-cell cDNA expression libraries. The sequence of one class of these cDNAs and the partial sequence of a corresponding genomic clone defined an open reading frame (ORF) encoding a 1010-amino-acid (aa) protein, individual domains of which showed high homology to each of the monofunctional bacterial GARS, AIRS and GART proteins, and to each domain of chicken and human trifunctional GARS-AIRS-GARTs. cDNAs corresponding to the smaller protein contained a 1.3-kb ORF with complete identity to the GARS domain of, but with a 3' untranslated region different from, the trifunctional cDNAs. Hence, both cDNAs appear to derive from the same gene due to either differential splicing or use of an intronic polyadenylation signal. The functional requirement for the expression of both trifunctional protein with GARS activity and monofunctional, catalytically active GARS is unknown.

Abstract
The symmetry of the responses of the human DNA (cytosine-5)methyltransferase to alternative placements of 5-methylcytosine in model oligodeoxynucleotide duplexes containing unusual structures has been examined. The results of these experiments more clearly define the DNA recognition specificity of the enzyme. A simple three-nucleotide recognition motif within the CG dinucleotide pair can be identified in each enzymatically methylated duplex. The data can be summarized by numbering the four nucleotides in the dinucleotide pair thus: 1 4/2 3. With reference to this numbering scheme, position 1 can be occupied by cytosine or 5-methylcytosine; position 2 can be occupied by guanosine or inosine; position 3, the site of enzymatic methylation, can be occupied only by cytosine; and position 4 can be occupied by guanosine, inosine, O6-methylguanosine, cytosine, adenosine, an abasic site, or the 3' hydroxyl group at the end of a gapped molecule. Replacing the guanosine normally found at position 4 with any of the moieties introduces unusual (non-Watson-Crick) pairing at position 3 and generally enhances methylation of the cytosine at that site. The exceptional facility of the enzyme in actively methylating unusual DNA structures suggests that the evolution of the DNA methyltransferase, and perhaps DNA methylation itself, may be linked to the biological occurrence of unusual DNA structures.
