Jennings, Lee D. published the artcileDesign and synthesis of indolo[2,3-a]quinolizin-7-one inhibitors of the ZipA-FtsZ interaction, HPLC of Formula: 18791-02-1, the publication is Bioorganic & Medicinal Chemistry Letters (2004), 14(6), 1427-1431, database is CAplus and MEDLINE.

The binding of FtsZ to ZipA is a potential target for antibacterial therapy. Based on a small mol. inhibitor of the ZipA-FtsZ interaction, a parallel synthesis of small mols. was initiated which targeted a key region of ZipA involved in FtsZ binding. The X-ray crystal structure of one of these mols. complexed with ZipA was solved. The structure revealed an unexpected binding mode, facilitated by desolvation of a loosely bound surface water.

Brown, Louise M. published the artcileThe destruction of cytochrome P-450 by alclofenac: possible involvement of an epoxide metabolite, HPLC of Formula: 33697-81-3, the publication is Biochemical Pharmacology (1982), 31(2), 195-9, database is CAplus and MEDLINE.

In control mouse hepatic microsomes, no evidence for metabolism of alclofenac (I) [22131-79-9] was observed, but in induced (phenobarbitone or 3-methylcholanthrene) microsomes, I was metabolized to the dihydroxy [41451-01-8] and phenolic [33697-81-3] metabolites. Destruction of cytochrome P-450  [9035-51-2] was observed when I was incubated with microsomes from phenobarbitone-treated mice, but not untreated or 3-methylcholanthrene-treated mice; the destruction was dependent on the presence of a NADPH-regenerating system and was inhibited by SKF 525A, metyrapone, glutathione, and cysteine. The metabolites caused no loss of cytochrome P-450, whereas the reactive intermediate, alclofenac epoxide  [70319-10-7], was a potent inducer in the absence of NADPH. Thus, in vitro destruction of cytochrome P-450 by I is partly mediated through the formation of the reactive epoxy metabolite.

Taylor, Adam C. published the artcileUse of Chemcatcher passive sampler with high-resolution mass spectrometry and multi-variate analysis for targeted screening of emerging pesticides in water, HPLC of Formula: 67747-01-7, the publication is Analytical Methods (2020), 12(32), 4015-4027, database is CAplus and MEDLINE.

Pesticides present at trace concentrations are a common cause of poor water quality. Screening generates large qual. data sets, therefore, there is a need for improved monitoring methods and data interpretation strategies to reduce the need for repetition, and increase the quality of information for end-users. Passive sampling is an in situ time integrative technique, increasingly used for monitoring pesticides in water. Here, we describe a method using the Chemcatcher passive sampler, coupled to targeted screening using liquid chromatog.-quadrupole-time-of-flight mass spectrometry, and a com. available library. Statistical anal. was performed using Agilent Mass Profiler Professional software. Water sampling took place over one year, at three riverine sites in the south of England, UK. Statistical interpretation of time integrative data from passive sampling could distinguish regular and episodic pesticide inputs, and detected compounds neglected by routine monitoring methods. One hundred and eleven pesticides were identified including legacy and current use compounds with diverse origins and uses. Spatial and temporal trends were identified enabling prioritisation of seasonal monitoring at each site. This approach maximises the utility of qual. assessment and may help water quality managers to rationalise pesticide fate in future, providing significant addnl. insight without the need to increase the scope and cost of monitoring.

(-)-Shikimic acid, was converted into both enantiomers of 2-hydroxyoxabicyclo[4.1.0]hept-3-ene-4-carboxylic acid which were attached to a solid support via a photocleavable linker. Tandem acylation-1,3-dipolar cycloaddition with nitrones yielded tetracyclic templates I. After development of several efficient coupling reactions of I and completion of extensive validation protocols, a split-pool synthesis yielded a binary encoded library calculated to contain 2.18 million polycyclic compounds These compounds are compatible with miniaturized cell-based forward chem. genetic assays designed to explore biol. pathways and reverse chem. genetic assays designed to explore protein function. As a simple illustration of the potential of these compounds, several were shown to activate a TGF-β-responsive reporter gene in mammalian cells.

Zorn, Kimberley M. published the artcileMachine Learning Models for Estrogen Receptor Bioactivity and Endocrine Disruption Prediction, Computed Properties of 637-07-0, the publication is Environmental Science & Technology (2020), 54(19), 12202-12213, database is CAplus and MEDLINE.

The U. S. Environmental Protection Agency (EPA) periodically releases in vitro data across a variety of targets, including the estrogen receptor (ER). In 2015, the EPA used this data to construct math. models of ER agonist and antagonist pathways to prioritize chems. for endocrine disruption testing. However, math. models require in vitro data prior to predicting estrogenic activity, but machine learning methods are capable of prospective prediction from mol. structure alone. The current study describes the generation and evaluation of Bayesian machine learning models grouped by the EPA’s ER agonist pathway model, using multiple data types with proprietary software, Assay Central. External predictions with three test sets of in vitro and in vivo reference chems. with agonist activity classifications were compared to previous math. model publications. Training datasets were subjected to addnl. machine learning algorithms and compared with rank normalized scores of internal five-fold cross-validation statistics. External predictions were found to be comparable or superior to previous studies published by the EPA. When assessing six addnl. algorithms for the training datasets, Assay CentralTM performed similarly at a reduced computational cost. This study demonstrates machine learning can prioritize chems. for future in vitro and in vivo testing of ER agonism.

Mistry, Nisha published the artcileCatalytic asymmetric synthesis of geminal-dicarboxylates, Related Products of chlorides-buliding-blocks, the publication is Chemical Science (2018), 9(29), 6307-6312, database is CAplus and MEDLINE.

Stereogenic acetals, spiroacetals and ketals are well-studied stereochem. features that bear two heteroatoms at a common carbon atom. These stereocenters are normally found in cyclic structures while linear (or acyclic) analogs bearing two heteroatoms are rare. Chiral geminal-dicarboxylates are illustrative, there is no current way to access this class of compounds while controlling the stereochem. at the carbon center bound to two oxygen atoms. Here, a rhodium-catalyzed asym. carboxylation of ester-containing allylic bromides to form stereogenic carbon centers bearing two different carboxylates with high yields and enantioselectivities is reported. The products, which are surprisingly stable to a variety of acidic and basic conditions, can be manipulated with no loss of enantiomeric purity as demonstrated by ring closing metathesis reactions to form chiral lactones, which have been extensively used as building blocks in asym. synthesis.

Cross, R. Matthew published the artcileOrally Bioavailable 6-Chloro-7-methoxy-4(1H)-quinolones Efficacious against Multiple Stages of Plasmodium, Recommanded Product: 4-Chloro-2-methylphenylboronic acid, the publication is Journal of Medicinal Chemistry (2014), 57(21), 8860-8879, database is CAplus and MEDLINE.

The continued proliferation of malaria throughout temperate and tropical regions of the world has promoted a push for more efficacious treatments to combat the disease. Unfortunately, more recent remedies such as artemisinin combination therapies have been rendered less effective due to developing parasite resistance, and new drugs are required that target the parasite in the liver to support the disease elimination efforts. Research was initiated to revisit antimalarials developed in the 1940s and 1960s that were deemed unsuitable for use as therapeutic agents as a result of poor understanding of both physicochem. properties and parasitol. Structure-activity and structure-property relationship studies were conducted to generate a set of compounds with the general 6-chloro-7-methoxy-2-methyl-4(1H)-quinolone scaffold which were substituted at the 3-position with a variety of Ph moieties possessing various properties. Extensive physicochem. evaluation of the quinolone series was carried out to down-select the most promising 4(1H)-quinolones, P4Q-391 (7), 6-Chloro-7-methoxy-2-methyl-3-(2-methyl-4-(4(trifluoromethoxy)phenoxy)phenyl)-quinolin-4(1H)-one (62), 6-Chloro-3-(6-(2-fluoro-4-(trifluoromethyl)phenyl)pyridin-3-yl)-7-methoxy-2-methylquinolin-4(1H)-one (66), and 6-Chloro-7-methoxy-2-methyl-3-(6-(4-(trifluoromethoxy)phenyl)pyridin-3-yl)quinolin-4(1H)-one(67), which possessed low-nanomolar EC₅₀ values against W2 and TM90-C2B as well as improved microsomal stability. Addnl., in vivo Thompson test results using Plasmodium berghei in mice showed that these 4(1H)-quinolones were efficacious for the reduction of parasitemia at >99% after 6 days.
