D’Ambrosio, Michele published the artcileNovel, racemic or nearly-racemic antibacterial bromo- and chloroquinols and γ-lactams of the verongiaquinol and the cavernicolin type from the marine sponge Aplysina (= Verongia) cavernicola, Formula: C8H7ClO3, the publication is Helvetica Chimica Acta (1984), 67(6), 1484-92, database is CAplus.

BuOH extracts of the Mediterranean sponge A. cavernicola gave, by reversed-phase HPLC, the antibacterial quinols (±)-3-bromoverongiaquinol (I) and (±)-3-bromo-5-chloroverongiaquinol (II) besides the products of formal cyclization 5-chlorocavernicolin (III) the C(7)-epimerizing 7β and 7α-bromo-5-chlorocavernicolins, and the C(7)-epimerizing 5-bromo-7β and 5-bromo-7α-chlorocavernicolins. The latter 4 were isolated as mixtures of C(7)-epimerizing monoacetates 4a’/4b’ and 5a’/5b’. Both I and II proved to be racemic from NMR examination of their esterification products with (-)-menthyloxyacetic acid, whereas III had âˆ?% enantiomeric purity as shown by a ¹H-NMR study of its monoacetate in the presence of a chiral shift reagent. These chiroptical data of the first chiral quinols from the Verongida and of III suggest phenol oxidative routes from tyrosine precursors for their formation. In view of their bioactivities, I and II were synthesized from (p-hydroxyphenyl)acetic acid by phenol oxidative routes.

Zhang, Zhimin published the artcileDiscovery of novel coumarin derivatives as potent and orally bioavailable BRD4 inhibitors based on scaffold hopping, COA of Formula: C9H5ClO4S, the publication is Journal of Enzyme Inhibition and Medicinal Chemistry (2019), 34(1), 808-817, database is CAplus and MEDLINE.

The bromodomain and extra-terminal (BET) bromodomains, particularly BRD4, have been identified as promising therapeutic targets in the treatment of many human disorders such as cancer, inflammation, obesity, and cardiovascular disease. Recently, the discovery of novel BRD4 inhibitors has garnered substantial interest. Starting from scaffold hopping of the reported compound dihydroquinazolinone (PFI-1), a series of coumarin derivatives were designed and synthesized as a new chemotype of BRD4 inhibitors. Interestingly, the representative compounds exhibited potent BRD4 binding affinity and cell proliferation inhibitory activity, and especially displayed a favorable PK profile with high oral bioavailability (F = 49.38%) and metabolic stability (T_1/2 = 4.2 h), meaningfully making it as a promising lead compound for further drug development.

Langston, Steven P. published the artcileDiscovery of TAK-981, a First-in-Class Inhibitor of SUMO-Activating Enzyme for the Treatment of Cancer, Formula: C7H6Cl2, the publication is Journal of Medicinal Chemistry (2021), 64(5), 2501-2520, database is CAplus and MEDLINE.

SUMOylation is a reversible post-translational modification that regulates protein function through covalent attachment of small ubiquitin-like modifier (SUMO) proteins. The process of SUMOylating proteins involves an enzymic cascade, the first step of which entails the activation of a SUMO protein through an ATP-dependent process catalyzed by SUMO-activating enzyme (SAE). Here, we describe the identification of TAK-981, a mechanism-based inhibitor of SAE which forms a SUMO-TAK-981 adduct as the inhibitory species within the enzyme catalytic site. Optimization of selectivity against related enzymes as well as enhancement of mean residence time of the adduct were critical to the identification of compounds with potent cellular pathway inhibition and ultimately a prolonged pharmacodynamic effect and efficacy in preclin. tumor models, culminating in the identification of the clin. mol. TAK-981.

MacSweeney, Aengus published the artcileDiscovery and Structure-Based Optimization of Adenain Inhibitors, Recommanded Product: 2-Chlorotrityl chloride, the publication is ACS Medicinal Chemistry Letters (2014), 5(8), 937-941, database is CAplus and MEDLINE.

The cysteine protease adenain is the essential protease of adenovirus and, as such, represents a promising target for the treatment of ocular and other adenoviral infections. Through a concise two-pronged hit discovery approach we identified tetrapeptide nitrile 1 and pyrimidine nitrile 2 as complementary starting points for adenain inhibition. These hits enabled the first high-resolution X-ray cocrystal structures of adenain with inhibitors bound and revealed the binding mode of 1 and 2. The screening hits were optimized by a structure-guided medicinal chem. strategy into low nanomolar drug-like inhibitors of adenain.

We report a method for cobalt-catalyzed, aminoquinoline-directed sp² C-H bond carbonylation of sulfonamides. The reactions proceed in a dichloroethane solvent, and employ diisopropyl azodicarboxylate as a carbon monoxide source, Mn(OAc)₂ as a cooxidant and potassium pivalate as a base. Halogen, ester, and amide functionalities are compatible with the reaction conditions. This method allows for a short and efficient synthesis of saccharin derivatives

De Pascale, G. published the artcileValidation for high-throughput screening of a VanRS-based reporter gene assay for bacterial cell wall inhibitors, Application of N-Benzyl-N,N-dibutylbutan-1-aminium chloride, the publication is Journal of Applied Microbiology (2007), 103(1), 133-140, database is CAplus and MEDLINE.

The present study was undertaken to validate, for antibiotic discovery, a reporter gene assay based on a Bacillus subtilis strain expressing the Enterococcus faecium vanRS genes and a vanH-lacZ fusion, which produced β-galactosidase activity in the presence of cell wall inhibitors (CWI) and lysozyme. The reporter assay was miniaturized, automated and validated with antibiotics and tested against portions of chem. and microbial extract libraries. The assay is simple, fast and reproducible and can detect all CWI, sometimes at concentrations lower than those necessary to inhibit bacterial growth. However, some membrane-interfering compounds also generate comparable signals. While most CWI elicit a signal that is transcription-dependent and abolished in an osmoprotective medium, transcription is not required for β-galactosidase activity brought about by the membrane-interfering compounds At least two distinct mechanisms appear to lead to enzymic activity in the reporter strain. Effective counterscreens can be designed to discard the undesired classes of compounds Extensive validation is required before introducing a reporter assay in high-throughput screening. However, the ease of operation and manipulation makes the reporter assays powerful tools for antibiotic discovery.

Buendia, Julien published the artcileThe Multiple Facets of Iodine(III) Compounds in an Unprecedented Catalytic Auto-amination for Chiral Amine Synthesis, Application In Synthesis of 866-23-9, the publication is Angewandte Chemie, International Edition (2016), 55(26), 7530-7533, database is CAplus and MEDLINE.

Iodine(III) reagents are used in catalytic one-pot reactions, first as both oxidants and substrates, then as cross-coupling partners, to afford chiral polyfunctionalized amines. The strategy relies on an initial catalytic auto C(sp³)-H amination of the iodine(III) oxidant, which delivers an amine-derived iodine(I) product that is subsequently used in palladium-catalyzed cross-couplings to afford a variety of useful building blocks with high yields and excellent stereoselectivities. This study demonstrates the concept of self-amination of the hypervalent iodine reagents, which increases the value of the aryl moiety.

Creighton, John A. published the artcileVibrational spectra of some trimethylsulfoxonium salts, -h9 and -d9, COA of Formula: C3H9ClOS, the publication is Spectrochimica Acta, Part A: Molecular and Biomolecular Spectroscopy (1969), 25(7), 1314-18, database is CAplus.

The ir (3650-40 cm.-1) and Raman spectra of (CD3)3,SOI as a solid, Raman data for Me3SOCl and Me3SOI as salts and for the former in aqueous solution have been obtained, and the ir spectra recorded to 50 cm.-1 For the cations there are 36 fundamentals which for C3v geometry divide by Γ = 8 a1 + 4a2 + 12e. The previous interpretation of Me3SOI (C., et al., 1967) is largely confirmed by the new results. The frequencies 1339 and 1318 cm.-1 are now taken as a1 and e, resp., rather than as the reverse of this since, for the corresponding Raman lines of the chloride in solution, that at 1348 cm.-1 appears polarized while that at 1313 cm.-1 is depolarized. The ν (C-S) modes are observed in the Raman spectra. A feature of particular note in the Raman spectrum of solid Me3SOI is the prominent line at 1371 cm.-1 which appears to have its counterpart for (CD3)3SOI at 990 cm.-1 The corresponding ir bands are very weak. Comparison is made with the fundamental frequencies for the isoelectronic mol. (CH3)3PO, with small changes in the assignment.
