Safety of 2,6-Difluorobenzoic acid. I found the field of Pharmacology & Pharmacy very interesting. Saw the article Synthesis, structural characterization and antimycobacterial evaluation of several halogenated non-nitro benzothiazinones published in 2021, Reprint Addresses Seidel, RW (corresponding author), Martin Luther Univ Halle Wittenberg, Inst Pharm, Wolfgang Langenbeck Str 4, D-06120 Halle, Saale, Germany.. The CAS is 385-00-2. Through research, I have a further understanding and discovery of 2,6-Difluorobenzoic acid.

8-Nitro-1,3-benzothiazin-4-ones (BTZs), with BTZ043 and PBTZ169 as the most advanced compounds, represent a new class of potent antitubercular agents, which irreversibly inhibit decaprenylphosphoryl-beta-d-ribose-2 ‘-epimerase (DprE1), an enzyme crucial for cell wall synthesis in the pathogen Mycobacterium tuberculosis. Synthesis, structural characterization and in vitro testing against Mycobacterium aurum DSM 43999 and M. tuberculosis H(37)Rv of halogenated 2-(4-ethoxycarbonylpiperazin-1-yl)-1,3-benzothiazin-4-ones lacking a nitro group are reported. X-ray crystallography reveals that the structure of the BTZ scaffold can significantly deviate from planarity. In contrast to recent reports, the results of the present study indicate that further investigation of halogenated non-nitro BTZs for antitubercular activity is less than a promising approach.

The coordination of biologically active moieties to the axial positions of Pt(IV) derivatives of Pt(II) anticancer drugs allows the co-delivery and simultaneous activation of two pro-drugs for combination therapy. Pt(IV) complexes with a redox modulator as an axial ligand can kill cancer cells by a mechanism combining DNA platination and generation of oxidative stress. In this study we evaluated the cytotoxicity of Pt(IV) complexes based on the oxaliplatin scaffold and the pro-oxidant indole-3-propionate in cisplatin-sensitive and cisplatin-resistant ovarian cancer cells. A series of five complexes was synthesized and characterized by H-1 and Pt-195 NMR spectroscopy, IR spectroscopy, mass spectrometry and elemental analysis; trans-[Pt(DACH)(ox)(IPA)(OH)] (1), trans-[Pt(DACH)(ox)(IPA)(2)] (2), trans-[Pt(DACH)(ox)(IPA)(bz)] (3), trans-[Pt(DACH)(ox)(IPA)(suc)] (4), and trans-[Pt(DACH)(ox)(IPA)(ac)] (5) (DACH = 1,2-diaminocyclohexane (1R, 2R)-(-), ox = oxalate, IPA = indole 3-propionate, bz = benzoate, suc = succinate and ac = acetate). The complexes were shown to produce cellular reactive oxygen species (ROS) in a time-dependent manner. The most potent ROS producer, complex 1, also elicited the highest cytotoxicity. Complex 1 was shown to form the mono-and bis-adducts [Pt(DACH)(guanosine)( OH)](+) and [Pt(DACH)(guanosine)(2)](2+) in the presence of ascorbic acid, suggesting that on activation the released oxaliplatin will interact with DNA.

Photoexcited electron-hole pairs on a semiconductor surface can engage in redox reactions with two different substrates. Similar to conventional electrosynthesis, the primary redox intermediates afford only separate oxidized and reduced products or, more rarely, combine to one addition product. Here, we report that a stable organic semiconductor material, mesoporous graphitic carbon nitride (mpg-CN), can act as a visible-light photoredox catalyst to orchestrate oxidative and reductive interfacial electron transfers to two different substrates in a two-or three-component system for direct twofold carbon-hydrogen functionalization of arenes and heteroarenes. The mpg-CN catalyst tolerates reactive radicals and strong nucleophiles, is straightforwardly recoverable by simple centrifugation of reaction mixtures, and is reusable for at least four catalytic transformations with conserved activity.

We recently reported a new class of chiral ruthenium catalysts in which two achiral bidentate N-(2-pyridyl)-substituted N-heterocyclic carbene ligands in addition to two labile acetonitriles are coordinated to a central ruthenium and generate a stereogenic metal center which is responsible for the overall chirality (Zheng et al. J. Am. Chem. Soc. 2017, 139, 4322). Here we now report our discovery of related chiral-at-ruthenium catalysts in which normal and abnormal N-heterocyclic carbene (NHC) ligands are present at the same time. The synthesis of racemic complexes, their resolution into individual enantiomers by a chiral auxiliary approach, and a catalytic application are reported. The mixed normal/abnormal NHC complexes display significantly increased turnover numbers and turnover frequencies for a nitrene-mediated enantioselective C(sp(3))-H amination.

I found the field of Chemistry very interesting. Saw the article Chemoselective Nucleophilic Functionalizations of Aromatic Aldehydes and Acetals via Pyridinium Salt Intermediates published in 2019.

The development of a novel chemoselective functionalization can diversify the strategy for synthesizing the target molecules. The perfect chemoselectivity between aromatic and aliphatic aldehydes is difficult to achieve by the previous methods. The aromatic aldehyde-selective nucleophilic addition in the presence of aliphatic aldehydes was newly accomplished. Namely, the aromatic aldehyde-selective nucleophilic addition using arenes and allyl silanes proceeded in the presence of trialkylsilyl triflate and 2,2′-bipyridyl, while the aliphatic aldehydes completely remained unchanged. The reactive pyridinium-type salt intermediate derived from an aromatic aldehyde chemoselectively underwent the nucleophilic substitution. Moreover, the aromatic acetals as the protected aldehydes could be directly transformed into similar pyridinium salt intermediates, which reacted with various nucleophiles coexisting with the aliphatic aldehydes.

Leishmaniasis being one of the six major tropical diseases that affects nearly 0.7-1.3 million people annually, has so far limited and high toxic therapeutic options. Herein, we report the synthesis, in silico, and in vitro evaluations of novel coumarin-incorporated isatin hydrazones (Spf-1 – Spf-10) as highly potent and safe antileishmanial agents. Molecular docking was initially carried out to decipher the binding confirmation of lead molecules towards the active cavity of the target protein (Leishmanolysin gp63) of Leishmania tropica. Among all the docked compounds, only Spf-6, Spf-8, and Spf-10 showed high binding affinities due to a pattern of strong conventional hydrogen bonds and hydrophobic pi-interactions. The molecular dynamics simulations showed the stable pattern of such bonding and structure-based confirmation with a time scale of 50 ns towards the top compound (Spf-10) and protein. These analyses affirmed the high stability of the system. Three out of ten compounds evaluated for their antileishmanial activity against Leishmania tropica promastigotes and amastigotes were found to be active at micromolar concentrations (IC50 range 0.1-4.13 mu mol/L), and most importantly, they were also found to be highly biocompatible when screened for their toxicity in human erythrocytes.

This work reports the synthesis of a novel quinolin-4(3H)-one based Schiff base ligand 3-[(E)-(2,5-dimethox-yphenyl)methylidene]amino-2-methylquinazolin-4(3H)-one (DMPAQ) and its coordination complexes of the type [M(DMPAQ)(phen)]X (1a-1c), where M = Cu(II), Zn(II) and Cd(II) ions, respectively, phen = 1,10-phe-nanthroline. All the synthesized compounds were characterized using UV-Visible, elemental analysis, FT-IR, H-1 NMR, Mass spectroscopy and TGA techniques. The triclinic structure of the DMPAQ is determined by employing single crystal X-ray crystallographic analysis. The characterization results suggested that the ligand, DMPAQ is bidentate and coordinate to the metal center through the lactum oxygen and the azomethine nitrogen. The synthesized DMPAQ ligand and complexes (1a-1c) were screened for their in vitro anticancer activity against the human breast adenocarcinoma cell line, MCF-7. The complexes 1a and 1b displayed significant anticancer ac-tivity against MCF-7 cells even at lower GI50 value (GI(50) = 0.016 mu M) than the standard drug doxorubicin (GI(50) = 0.018 mu M). Further, we have performed computational DFT studies on the chemical reactivity of the ligand and the three complexes by means of Conceptual Density Functional Theory (CDFT) through the Koopmans in DFT (KID) approximation to support the experimentally obtained results.

We report the on-demand generation of hexane-soluble (2-ethylhexyl)sodium (1) from 3-(chloromethyl)heptane (2) using a sodium-packed-bed reactor under continuous flow conditions. Thus, the resulting solution of 1 is free of elemental sodium and therefore suited for a range of synthetic applications. This new procedure avoids the storage of an alkylsodium and limits the handling of metallic sodium to a minimum. (2-Ethylhexyl)sodium (1) proved to be a very useful reagent and undergoes in-line Br/Na-exchanges as well as directed sodiations. The resulting arylsodium intermediates are subsequently trapped in batch with various electrophiles such as ketones, aldehydes, Weinreb-amides, imines, allyl bromides, disulfides and alkyl iodides. A reaction scale-up of the Br/Na-exchange using an in-line electrophile quench was also reported.
