High-throughput screening of a library of small polar mols. against Mycobacterium tuberculosis led to the identification of a phthalimide-containing ester hit compound I, which was optimized for metabolic stability by replacing the ester moiety with a Me oxadiazole bioisostere. A route utilizing polymer-supported reagents was designed and executed to explore structure-activity relationships with respect to the N-benzyl substituent, leading to compounds with nanomolar activity. The front runner compound II from these studies was well tolerated in mice. A M. tuberculosis cytochrome bd oxidase deletion mutant (ΔcydKO) was hyper-susceptible to compounds from this series, and a strain carrying a single point mutation in qcrB, the gene encoding a subunit of the menaquinol cytochrome c oxidoreductase, was resistant to compounds in this series. In combination, these observations indicate that this novel class of antimycobacterial compounds inhibits the cytochrome bc1 complex, a validated drug target in M. tuberculosis.

van der Veen, Ike;Schellenberger, Steffen;Hanning, Anne-Charlotte;Stare, Ann;de Boer, Jacob;Weiss, Jana M.;Leonards, Pim E. G. research published 《 Fate of Per- and Polyfluoroalkyl Substances from Durable Water-Repellent Clothing during Use》, the research content is summarized as follows. To make outdoor clothing water- or dirt-repellent, durable water-repellent (DWR) coatings based on side-chain fluorinated polymers (SFPs) are used. During use of outdoor clothing, per- and polyfluoroalkyl substances (PFASs) can be emitted from the DWR to the environment. In this study, the effects of aging, washing, and tumble drying on the concentration of extractable PFASs in the DWR of perfluorohexane-based short-chain SFPs (FC-6 chem.) and of perfluorooctane-based long-chain SFPs (FC-8 chem.) were assessed. For this purpose, polyamide (PA) and polyester (PES) fabrics were coated with FC-6- and FC-8-based DWRs. Results show that aging of the coated fabrics causes an increase in concentration and formation of perfluoroalkyl acids (PFAAs). The effect of aging on the volatile PFASs depends on the type of fabric. Washing causes a decrease in PFAA concentrations, and in general, volatile PFASs are partly washed out of the textiles. However, washing can also increase the extractable concentration of volatile PFASs in the fabrics. This effect becomes stronger by a combination of aging and washing. Tumble drying does not affect the PFAS concentrations in textiles. In conclusion, aging and washing of fabrics coated with the DWR based on SFPs release PFASs to the environment.

van der Veen, Ike;Hanning, Anne-Charlotte;Stare, Ann;Leonards, Pim E. G.;de Boer, Jacob;Weiss, Jana M. research published 《 The effect of weathering on per- and polyfluoroalkyl substances (PFASs) from durable water repellent (DWR) clothing》, the research content is summarized as follows. To assess the effects of weathering on per- and polyfluoroalkyl substances (PFASs) from durable water repellent (DWR) clothing, thirteen com. textile samples were exposed to elevated ultra violet (UV) radiation, humidity, and temperature in an aging device for 300 h, which mimics the lifespan of outdoor clothing. Before and after aging, the textile samples were extracted and analyzed for the ionic PFASs (perfluoroalkyl acids (PFAAs), perfluorooctane sulfonamide (FOSA)) and volatile PFASs (fluorotelomer alcs. (FTOHs), acrylates (FTACs) and methacrylates (FTMACs)). Results showed that weathering can have an effect on PFASs used in DWR of outdoor clothing, both on the PFAS profile and on the measured concentrations In most weathered samples the PFAA concentrations increased by 5- to more than 100-fold, while PFAAs not detected in the original textiles were detected in the weathered samples. DWR chemistries are based on side-chain fluorinated polymers. A possible explanation for the increase in concentration of the PFAAs is hydrolysis of the fluorotelomer based polymers (FTPs), or degradation of the FTOHs, which are used in the manufacturing of the FTPs. The concentrations of volatile PFASs also increased, by a factor up to 20. Suggested explanations are the degradation of the DWR polymers, making non-extractable fluorines extractable, or the transformation or degradation of unknown precursors. Further research is needed to unravel the details of these processes and to determine the transformation routes. This study shows that setting maximum tolerance limits only for a few individual PFASs is not sufficient to control these harmful substances in outdoor clothing.

Upadhyay, Prabhat;Shukla, Rashmi;Tiwari, Kavindra Nath;Dubey, G. P.;Mishra, Sunil Kumar research published 《 Neuroprotective effect of Reinwardtia indica against scopolamine induced memory-impairment in rat by attenuating oxidative stress》, the research content is summarized as follows. Reinwardtia indica belongs to Linaceae family and used as a folk medicine in Asian countries. Traditionally, it has been used in the treatment of paralysis and anti-microbial in wound healing, etc. The current study was undertaken in order to investigate the antioxidant and memory protective effect of the alc. (99.90%) (AERI) and hydro-alc. (70:30) leaves extract (HAERI) of Reinwardtia indica, against scopolamine-induced memory impairment in animals and also tried to determine the possible mechanism of action. In addition, phytochem. profiling of alc. leaves extract was also conducted through gas chromatog.-mass spectrometry. Rats were pretreated with AERI, HAERI (dose 250 and 500 mg/kg) and Donepezil (standard drug) along with scopolamine (1 mg/kg) for a period of 14 days followed by different test like elevated plus maze, passive avoidance, and Morris water maze to assess learning and memory ability. Acetylcholine levels, acetylcholinesterase (AChE), antioxidant enzymes (SOD, CAT & GSH), histopathol. of the brain and biochem. test were also performed at the end of the treatment period. The scopolamine treatment resulted in learning and memory deficits which were partially and significantly ameliorated by the AERI at higher dose among other doses of extracts The AERI at higher dose also counteracted the scopolamine-induced decrease in acetylcholine levels, increase in AChE activity, and decrease in antioxidant enzymes activities. No significant changes observed in the biochem. estimation of all dose of extracts Histol. of brain tissue showed the marked cellular changes in only scopolamine treated group while the standard, AERI and HAERI treated group were showing less damage at hippocampus region of the brain. The phytochems. found after chem. profiling through GC-MS also supported the activity because of the presence of chems. already reported for the neuroprotective, memory-enhancing and antioxidant activity, etc. The results demonstrated that the ability of the AERI at higher dose among all doses of extracts has more potential to revert the scopolamine-induced learning and memory deficits in rats by attenuating the decreased level of acetylcholine and antioxidant enzymes.

Uno, Shinpei;Masuya, Takahiro;Shinzawa-Itoh, Kyoko;Lasham, Jonathan;Haapanen, Outi;Shiba, Tomoo;Inaoka, Daniel Ken;Sharma, Vivek;Murai, Masatoshi;Miyoshi, Hideto research published 《 Oversized ubiquinones as molecular probes for structural dynamics of the ubiquinone reaction site in mitochondrial respiratory complex I》, the research content is summarized as follows. NADH-quinone oxidoreductase (complex I) couples electron transfer from NADH to quinone with proton translocation across the membrane. Quinone reduction is a key step for energy transmission from the site of quinone reduction to the remotely located proton-pumping machinery of the enzyme. Although structural biol. studies have proposed the existence of a long and narrow quinone-access channel, the physiol. relevance of this channel remains debatable. We investigated here whether complex I in bovine heart submitochondrial particles (SMPs) can catalytically reduce a series of oversized ubiquinones (OS-UQs), which are highly unlikely to transit the narrow channel because their side chain includes a bulky “block” that is ∼13 Å across. We found that some OS-UQs function as efficient electron acceptors from complex I, accepting electrons with an efficiency comparable with ubiquinone-2. The catalytic reduction and proton translocation coupled with this reduction were completely inhibited by different quinone-site inhibitors, indicating that the reduction of OS-UQs takes place at the physiol. reaction site for ubiquinone. Notably, the proton-translocating efficiencies of OS-UQs significantly varied depending on their side-chain structures, suggesting that the reaction characteristics of OS-UQs affect the predicted structural changes of the quinone reaction site required for triggering proton translocation. These results are difficult to reconcile with the current channel model; rather, the access path for ubiquinone may be open to allow OS-UQs to access the reaction site. Nevertheless, contrary to the observations in SMPs, OSUQs were not catalytically reduced by isolated complex I reconstituted into liposomes. We discuss possible reasons for these contradictory results.

Ueoka, Reiko;Bortfeld-Miller, Miriam;Morinaka, Brandon I.;Vorholt, Julia A.;Piel, Joern research published 《 Toblerols: cyclopropanol-containing polyketide modulators of antibiosis in Methylobacteria》, the research content is summarized as follows. Trans-AT polyketide synthases (PKSs) are a family of biosynthetically versatile modular type I PKSs that generate bioactive polyketides of impressive structural diversity. In this study, we detected, in the genome of several bacteria a cryptic, architecturally unusual trans-AT PKS gene cluster which eluded automated PKS prediction. Genomic mining of one of these strains, the model methylotroph Methylobacterium extorquens AM1, revealed unique epoxide- and cyclopropanol-containing polyketides named toblerols. Relative and absolute stereochem. were determined by NMR experiments, chem. derivatization, and the comparison of CD data between the derivatized natural product and a synthesized model compound Biosynthetic data suggest that the cyclopropanol moiety is generated by carbon-carbon shortening of a more extended precursor. Surprisingly, a knock-out strain impaired in polyketide production showed strong inhibitory activity against other methylobacteria in contrast to the wild-type producer. The activity was inhibited by complementation with toblerols, thus suggesting that these compounds modulate an as-yet unknown methylobacterial antibiotic.

The farnesoid X receptor (FXR) is a nuclear receptor that acts as a master regulator of bile acid metabolism and signaling. Activation of FXR inhibits bile acid synthesis and increases bile acid conjugation, transport, and excretion, thereby protecting the liver from the harmful effects of bile accumulation, leading to considerable interest in FXR as a therapeutic target for the treatment of cholestasis and nonalcoholic steatohepatitis. We identified a novel series of highly potent non-bile acid FXR agonists that introduce a bicyclic nortropine-substituted benzothiazole carboxylic acid moiety onto a trisubstituted isoxazole scaffold. Herein, we report the discovery of 1 (tropifexor, LJN452), a novel and highly potent agonist of FXR. Potent in vivo activity was demonstrated in rodent PD models by measuring the induction of FXR target genes in various tissues. Tropifexor has advanced into phase 2 human clin. trials in patients with NASH and PBC.

Proprotein convertase subtilisin-like/kexin type 9 (PCSK9) is a key regulator of plasma LDL-cholesterol (LDL-C) and a clin. validated target for the treatment of hypercholesterolemia and coronary artery disease. Starting from second-generation lead structures such as 2, we were able to refine these structures to obtain extremely potent bi- and tricyclic PCSK9 inhibitor peptides. Optimized mols. such as 44 demonstrated sufficient oral bioavailability to maintain therapeutic levels in rats and cynomolgus monkeys after dosing with an enabled formulation. We demonstrated target engagement and LDL lowering in cynomolgus monkeys essentially identical to those observed with the clin. approved, parenterally dosed antibodies. These mols. represent the first report of highly potent and orally bioavailable macrocyclic peptide PCSK9 inhibitors with overall profiles favorable for potential development as once-daily oral lipid-lowering agents. In this manuscript, we detail the design criteria and multiparameter optimization of this novel series of PCSK9 inhibitors.
