The pyridoxal 5?-phosphate (PLP)-dependent transaminase BioA catalyzes the second step in the biosynthesis of biotin in Mycobacterium tuberculosis (Mtb) and is an essential enzyme for bacterial survival and persistence in vivo. A promising BioA inhibitor 6 containing an N-aryl, N?-benzoylpiperazine scaffold was previously identified by target-based whole-cell screening. Here, we explore the structure-activity relationships (SAR) through the design, synthesis, and biological evaluation of a systematic series of analogues of the original hit using a structure-based drug design strategy, which was enabled by cocrystallization of several analogues with BioA. To confirm target engagement and discern analogues with off-target activity, each compound was evaluated against wild-type (WT) Mtb in biotin-free and -containing medium as well as BioA under- and overexpressing Mtb strains. Conformationally constrained derivative 36 emerged as the most potent analogue with a KD of 76 nM against BioA and a minimum inhibitory concentration of 1.7 muM (0.6 mug/mL) against Mtb in biotin-free medium.

Phosphinic acids, RfP(O)(OH)H (Rf=CF3, C2F5, C6F5), turned out to be excellent preligands for the coordination of phosphonous acids, RfP(OH)2. Addition of C2F5P(O)(OH)H to solid PtCl2 under different reaction conditions allows the isolation and full characterization of the mononuclear complexes [ClPt{P(C2F5)(OH)O}{P(C2F5)(OH)2}2] and [Pt{P(C2F5)(OH)O}2{P(C2F5)(OH)2}] containing hydrogen-bridged [RfP(OH)O]- and RfP(OH)2 units. Further deprotonation of [Pt{P(C2F5)(OH)O}2{P(C2F5)(OH)2}2] leads to the formation of the dianionic platinate, [Pt{P(C2F5)(OH)O}4]2-, revealing four intramolecular hydrogen bridges. With PdCl2 the dinuclear complex [Pd2(mu-Cl)2{[P(C2F5)(OH)O]2H}2] was isolated and characterized. The Cl- free complex [Pd{P(C2F5)(OH)O}2{P(C2F5)(OH)2}2] was also prepared and deprotonated to the dianionic palladate, [Pd{P(C2F5)(OH)O}4]2-. Both compounds were characterized by NMR spectroscopy, IR spectroscopy, and X-ray analyses. In addition, the C6F5 derivatives [ClPt{P(C6F5)(OH)O}{P(C6F5)(OH)2}2] and [Pd2(mu-Cl)2{[P(C6F5)(OH)O]2H}2] as well as the CF3 derivative [Pd2(mu-Cl)2{[P(CF3)(OH)O]2H}2] were synthesized and fully characterized. Phosphonous acid complexes are inert towards air and moisture and can be stored for several months without decomposition. The catalytic activity of the palladium complexes in the Suzuki cross-coupling reaction between 1-bromo-3-fluorobenzene and phenyl boronic acid was demonstrated. A tautomeric equilibrium between phosphinic, RP(O)(OH)H, and phosphonous acids, RP(OH)2, is evidenced by this work (see figure). The coordination properties of phosphonous acids with electron-withdrawing CF3, C2F5, and C6F5 groups is also described.

Kinetic, spectroscopic, crystallographic, and computational studies probing a Pd-catalyzed C-H arylation reaction reveal that mono-oxidation of the bis-phosphine ligand is critical for the formation of the active catalyst. The bis-phosphine mono-oxide is shown to be a hemilabile, bidentate ligand for palladium. Isolation of the oxidative addition adduct, with structural elucidation by X-ray analysis, showed that the mono-oxide was catalytically competent, giving the same reaction rate in the productive reaction as the Pd(II)/xantphos precursor. A dual role for the carboxylate base in both catalyst activation and reaction turnover was demonstrated, along with the inhibiting effect of excess phosphine ligand. The generality of the role of phosphine mono-oxide complexes in Pd-catalyzed coupling processes is discussed.

The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 52409-22-0, Pd2(DBA)3, introducing its new discovery.

The first C2-selective alkynylation of indoles using the hypervalent iodine reagent triisopropylsilylethynyl-1,2-benziodoxol-3(1H)-one (TIPS-EBX) with Pd(II) as a catalyst is described. This convenient and robust method gives a single-step access to substituted alkynyl indoles with very high C2 selectivity. The reaction is orthogonal to classical Pd(0) cross-coupling reactions, as it is tolerant to bromide and iodide substituents. The used silyl protecting group can be easily removed to give terminal acetylenes.

A new tandem palladium-catalyzed reaction involving a Suzuki-Miyaura coupling, a desulfenylative coupling, and a hydrothiolation of a triple bond is reported. Notably, the desulfenylative coupling occurs without copper(I) assistance and the hydrothiolation is totally regioselective and stereoselective. The overall process results in the double incorporation of the boronic acid and the reincorporation of the sulfenyl moiety into the product structure. Starting from 2-(bromobenzylsulfenyl)-1-propargyl benzimidazoles, the transformation led to variously substituted benzimidazoles bearing a stereodefined alkenyl sulfide.

Bipolar hosts derived from dibenzothiophene and indolocarbazole were developed for usage in blue phosphorescent organic light-emitting diodes (PhOLEDs). The 4 position of dibenzothiophene and the 2 position of indolocarbazole were used to couple the dibenzothiophene and indolocarbazole. Two hosts, with and without a pi linker, were synthesized, characterized, and explored as hosts for a blue phosphorescent emitter. The blue PhOLEDs fabricated using the new hosts demonstrate high external quantum efficiency over 18%.

Reactive oxygen species play numerous roles in a number of pathological processes. Monitoring H2O2 is a powerful tool for imaging and therapy of diseases wherein oxidative stress is involved. In particular, we report a specific application of functional microspheres as sensors of H2O2. Reactive oxygen species responsive delivery systems were developed to detect in vitro peroxides thanks to the presence of a boronic ester which is readily cleaved with H2O2. This ROS-sensitive cleavable linker underwent a 1,6-elimination to disrupt fluorescence resonance energy transfer by coupled near-infrared fluorophores such as Cy5.5/Cy7. This technology would allow real-time monitoring of therapeutic regimes (and their success), as well as optical detection of inflammation.

A general Pd-catalyzed intermolecular reductive Heck reaction of both terminal and internal unactivated aliphatic alkenes has been first developed. This method affords gamma- and delta-arylated alkyl carboxylic acid derivatives in high yields with complete anti-Markovnikov selectivity. Notably, the coupling process is stereoretentive for the alkyl chain. Mechanistically, alkyl palladacycle intermediates stabilized by directing group and ligand, hydride species multigenerated from PS/TFA reductant, are two key factors that successfully promote the reaction and regioselectivity.

The aim of the present review is to report the state of the art of an emerging family of molecules, namely 4-substituted spirobifluorenes (SBFs). Their syntheses, physico-chemical and photophysical properties and applications as hosts in Phosphorescent Organic Light-Emitting diodes (PhOLEDs) are described through a structure-property relationship approach. Although substitution at position 2 of a SBF core has been widely developed, substitution at position 4 is very recent (less than 10 years) and stills need to be explored.
