Anti-Stokes Stress Sensing: Mechanochemical Activation of Triplet?Triplet Annihilation Photon Upconversion

The development of methods to detect damage in macromolecular materials is of paramount importance to understand their mechanical failure and the structure?property relationships of polymers. Mechanofluorophores are useful and sensitive molecular motifs for this purpose. However, to date, tailoring of their optical properties remains challenging and correlating emission intensity to force induced material damage and the respective events on the molecular level is complicated by intrinsic limitations of fluorescence and its detection techniques. Now, this is tackled by developing the first stress-sensing motif that relies on photon upconversion. By combining the Diels?Alder adduct of a pi-extended anthracene with the porphyrin-based triplet sensitizer PtOEP in polymers, triplet?triplet annihilation photon upconversion of green to blue light is mechanochemically activated in solution as well as in the solid state.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 1585-90-6 is helpful to your research. 1585-90-6

Dimeric Drug Polymeric Micelles with Acid-Active Tumor Targeting and FRET-Traceable Drug Release

Trans-activating transcriptional activator (TAT), a cell-penetrating peptide, is extensively used for facilitating cellular uptake and nuclear targeting of drug delivery systems. However, the positively charged TAT peptide strongly interacts with serum components and undergoes substantial phagocytosis by the reticuloendothelial system, causing a short blood circulation in vivo. In this work, an acid-active tumor targeting nanoplatform DA-TAT-PECL is developed to inhibit the nonspecific interactions of TAT in the bloodstream. 2,3-dimethylmaleic anhydride (DA) is used to convert the TAT’s amines to carboxylic acid; the resulting DA-TAT is conjugated to poly(ethylene glycol)-poly(epsilon-caprolactone) (PEG-PCL, PECL) to get DA-TAT-PECL. After self-assembly into polymeric micelles, they are capable of circulating in the physiological condition for a long time and promoting cell penetration upon accumulation at the tumor site and deshielding the DA group. Moreover, camptothecin (CPT) is used as the anticancer drug and modified into a dimer (CPT)2-ss-Mal, in which two CPT molecules are connected by a reduction-labile maleimide thioether bond. The Foerster resonance energy transfer signal between CPT and maleimide thioether bond is monitored to visualize the drug release process, and effective targeted delivery of antitumor drugs is demonstrated. This pH/reduction dual-responsive micelle system provides a new platform for high fidelity cancer therapy.

Hypepontine, a new quaternary alkaloid with antimicrobial properties

New isoquinoline alkaloid hypepontine (1) together with a five known compounds, were identified in Hypecoum ponticum Velen, the partial synonym of Hypecoum procumbens L. The structure of the new substance was elucidated based on spectroscopic evidence. The tertiary and quaternary alkaloid mixtures as well as the isolated alkaloids were evaluated for their antibacterial and antifungal activity. The result revealed that the crude alkaloid mixture containing quaternary isoquinoline alkaloids showed potent antifungal and antibacterial activity.

Microwave-assisted synthesis and structure-activity relationships of neuroactive pyrazolo[3,4-b]pyrrolo[3,4-d]pyridine derivatives

We described herein the optimization of the synthetic methodology exploited to obtain the pyrazolo[3,4-b]pyrrolo[3,4-d]pyridine sedative prototype 1a and novel analogues designed by successive molecular simplifications. By applying microwave irradiation during the hetero Diels-Alder key-step to obtain the heterotricyclic scaffold, under solvent-free conditions, we were able to obtain the desired compounds in drastically shorter times and better yields. Additionally, in vivo evaluation of the sedative effects of these heterocyclic derivatives showed that 1a and the novel structurally-related analogue 1e were the most efficient compounds to impair the locomotor activity in mice at the dose of 10 mumol/kg.

Organotin complexes containing carboxylate ligands with maleimide and naphthalimide derived partial structures: TrxR inhibition, cytotoxicity and activity in resistant cancer cells

Di-n-butyltin(IV) carboxylate and tri-n-butyltin(IV) carboxylate derivatives have demonstrated strong cytotoxic effects in different types of tumor cells. Complexes with carboxylate ligands that contain maleimide and naphthalimide derived partial structures were synthesized, characterized and investigated for inhibition of the tumor-relevant enzyme thioredoxin reductase and antiproliferative effects in cancer cells. The complexes were moderate inhibitors of thioredoxin reductase with activities in the micromolar range and triggered strong cytotoxic effects in MCF-7 breast cancer and HT-29 colon carcinoma cells. Interestingly, selected complexes were highly active in vincristine and daunorubicin resistant Nalm-6 cells.

Shape-Memory-Self-Healing Polymers (SMSHPS)

A shape-memory self-healing polymeric network (SMSHP) is useful as a molded part, a coating, or as a matrix for a composite that can be repaired by heating to a controlled temperature. The SMSHP has thermally reversible repeating units where a thermally reversible adduct is situated between two common linking units formed during a polymerization process between thermally reversible monomers and cross-linking monomers. Optionally, other repeating units can be present from other monomers. Shape-memory results when the SMSHP is warmed to a temperature in excess of its glass transition temperature and self-healing then proceeds when a higher temperature is achieved where thermally reversible adducts dissociates to complementary groups that subsequently reform the adduct without distortion of the memorized shape. The thermally reversible adducts can be Diels-Alder (DA) adducts in a polyurethane, poly urea, or amine epoxy SMSHP network.

9,10-Dibromo-N-aryl-9,10-dihydro-9,10-[3,4]epipyrroloanthracene-12,14-diones: Synthesis and Investigation of Their Effects on Carbonic Anhydrase Isozymes I, II, IX, and XII

N-substituted maleimides were synthesized from maleic anhydride and primary amines. 1,4-Dibromo-dibenzo[e,h]bicyclo-[2,2,2]octane-2,3-dicarboximide derivatives (4a-f) were prepared by the [4+2] cycloaddition reaction of dibromoanthracenes with the N-substituted maleimide derivatives. The carbonic anhydrase (CA, EC 4.2.1.1) inhibitory effects of the new derivatives were assayed against the human (h) isozymes hCA I, II, IX, and XII. All tested bicyclo dicarboximide derivatives exhibited excellent inhibitory effects in the nanomolar range, with Ki values in the range of 117.73-232.87 nM against hCA I and of 69.74-111.51 nM against hCA II, whereas they were low micromolar inhibitors against hCA IX and XII. A series of 9,10-dibromo-N-aryl-9,10-dihydro-9,10-[3,4]epipyrroloanthracene-12,14-diones (4a-f) were synthesized from N-substituted maleimide derivatives and 9,10-dibromoanthracene. Compounds 4a-f were assayed against human carbonic anhydrases (hCA) IX and XII, which are the two tumor-associated isozymes, and hCA I and II, which represent the most common off-targets for the development of selective anticancer CA inhibitors.

An efficient transformation of cyclic ene-carbamates into omega-(N-formylamino)carboxylic acids by ruthenium tetroxide oxidation

The ruthenium tetroxide (RuO4) oxidation of cyclic ene-carbamates resulted in the endo-cyclic carbon-carbon double bond cleavage to afford the corresponding omega-(N-formylamino)carboxylic acids in good yields. Substituted cyclic ene-carbamates derived from (3R)-3-hydroxypiperidine hydrochloride were converted into the N-Boc 4-aminobutyric acids by utilization of the RuO4 oxidation as the key step, which were further transformed into (3R)-4-amino-3-hydroxybutyric acid, an important key intermediate for the synthesis of L-carnitine.
