Condensation of 4,2-R(O₂N)C₆H₃Cl (R = H, Cl) with 2-H₂NC₆H₄CO₂H gave 2-[4,2-R(O₂N)C₆H₃NH]C₆H₄CO₂H (same R). The reduction of the latter gave 2-[4,2-R(H₂N)C₆H₃NH]C₆H₄CO₂H which upon cyclocondensation gave 5,10-dihydro-11H-dibenzo[b,e][1,4]diazepin-11-one and its 8-chloro derivative The latter products were acylated or methylated and acylated to give 5-acyl-5,10-dihydro-11H-dibenzo[b,e][1,4]diazepin-11-ones I (R = H, Cl; R¹ = H, Me; R² = Cl, CH₂Cl, etc.); the I thus obtained were aminated to give I [R = H, Cl; R¹ = H, Me; R² = N(CH₂CH₂OH)₂, NMe(CH₂CH₂OH), etc.] (II). The ulcer-inhibiting activity of II was postulated; II (R = Cl; R¹ = H; R² = N(CH₂CH₂)H)].HCl, i.e. AWD 26-06, is selected for clin. evaluation (no data). II thus prepared differ from other tricyclic psychopharmaceuticals in their lipid solubility and hence have no effect as central nervous system agents.

Ruiz Montoya, M. published the artcileA Contribution to the Elucidation of the Reduction Mechanism of 2-Chloroisonicotinic Acid on Mercury Electrodes, Recommanded Product: 2-Chloroisonicotinic acid, the publication is Journal of the Electrochemical Society (2008), 155(8), F190-F195, database is CAplus.

This paper presents polarog. (d.c. and differential pulse) and voltammetric (linear-sweep cyclic voltammetric) studies of the electroreduction of 2-chloroisonicotinic acid (2-chloro-4-pyridinecarboxylic acid), 2-CISO, at Hg electrodes. The dissociation constants of 2-CISO were obtained from the UV-visible absorption spectra (pK of 0.5 ± 0.03 corresponding to the -COOH group) and by potentiometric titration (pK of 3.46 corresponding to the protonation-dissociation of the heterocyclic N). The electrochem. studies were performed in the acidity range 2.7M H₂SO₄ to pH 7. Above the last pH value no signals were observed The overall reduction process involves the uptake of 4 electrons. Kinetics parameters such as Tafel slopes and electrochem. reaction orders were determined at potentials corresponding to the foot of the waves. A reaction mechanism can be proposed, consisting of an electrochem.-chem. process having 2 reversible electron transfers preceding a chem. step. At the scan rates used in cyclic voltammetry, the rate-determining step is the 2nd irreversible electron transfer. At pH°0.5 the recombination of the carboxylate anion with the H⁺ ion takes place prior to the reduction process.

The reaction of indoline with a substituted benzoyl chloride in the presence of K₂CO₃ in THF gave 1-aroyl-2,3-dihydro-1H-indole I. The latter was subjected to chlorosulfonation in position 5. Condensation of the latter with aromatic amines led 1-aroyl-2,3-dihydro-1H-indole-5-sulfonamides. Similarly, 5-nitroindoline was treated with a substituted benzoyl chloride to obtain the nitro compound II, which was reduced using stannous chloride and reacted further with aromatic sulfonyl chloride to obtain the N-[1-aroyl-2,3-dihydro-1H-indol-5-yl]sulfonamides. These compounds were tested for antibacterial, tuberculostatic, and antifungal activity. Some of them showed very good activity against some gram-pos. and gram neg. bacteria, fungal strains, and also Mycobacterium tuberculosis. All of the synthesized compounds were subjected to antioxidant activity testing using the in vitro DPPH assay, and most of them showed very good activity.

Chen, Xingchen published the artcilePotent, multi-target serine protease inhibition achieved by a simplified β-sheet motif, Application In Synthesis of 42074-68-0, the publication is PLoS One (2019), 14(1), e0210842, database is CAplus and MEDLINE.

Engagement of an extended β-sheet is a common substrate/inhibitor interaction at the active site of serine proteases and is an important feature of Laskowski mechanism inhibitors that present a substrate-like loop to a target protease. This loop is cleaved but subsequently relegated forming a stable inhibitor/protease complex. Laskowski inhibitors are ubiquitous in nature and are used extensively in serine protease inhibitor design. However, most studies concentrate on introducing new sidechain interactions rather than the direct contributions of the substrate-like β-sheet to enzyme inhibition. Here we report the crystal structure of an simplified β-sheet inhibitory motif within the Sunflower Trypsin Inhibitor (SFTI) in complex with trypsin. We show that the intramol. hydrogen bond network of this SFTI variant (SFTI-TCTR) engages the inhibitor sidechains that would normally interact with a target protease, giving mainchain interactions a more prominent role in complex formation. Despite having reduced sidechain interactions, this SFTI variant is remarkably potent and inhibits a diverse range of serine proteases. Crystal structural anal. and mol. modeling of SFTI-TCTR complexes again indicates an interface dominated by β-sheet interactions, highlighting the importance of this motif and the adaptability of SFTI as a scaffold for inhibitor design.

Geer, B. W. published the artcileThe growth effects of carnitine, deoxycarnitine, and sulfocholine for Drosophila, Neurospora, and Saccharomyces, Related Products of chlorides-buliding-blocks, the publication is Growth (1965), 29(4), 405-13, database is CAplus.

The physiol. activities of choline (I) were studied in Saccharomyces carlsbergensis, a I-requiring strain of Neurospora crassa, and Drosophila melanogaster. The related compounds deoxycarnitine (II), carnitine (III), and sulfocholine (IV) were then substituted for dietary I. IV was more effective than I in inhibiting the growth response of S. carlsbergensis to inositol, was slightly less effective than I in promoting the growth of I-requiring N. crassa, and was ∼50% as effective as I in stimulating the growth of D. melanogaster larvae. II and III were ineffective in the Neurospora and Saccharomyces systems, but were nearly as effective as I in the Drosophila system. Thus, the Neurospora and Saccharomyces systems are fundamentally similar in their responses to the test compounds The ability to utilize dietary II and III effectively for growth in place of I apparently evolved within the insect order Diptera.

Hasanebrahimi, Gholamreza published the artcileExploring beneficial structural features of ionic surfactants for wettability alteration of carbonate rocks using QSPR modeling technique, Related Products of chlorides-buliding-blocks, the publication is Journal of Molecular Liquids (2017), 196-208, database is CAplus.

Surfactant induced wettability alteration of reservoir rocks is an efficient process that enhances oil recovery of carbonate reservoirs. Finding a suitable surfactant for such a process is an interesting challenge in petroleum industry. To this purpose, generating a database of surfactant properties would be a good idea but property measurement of hundreds of surfactants and then screening them is a highly time consuming and expensive method. Therefore, the application of a math. model for prediction of surfactant properties may well be so helpful for our purpose. Quant. structure-property relationship (QSPR) is a math. model that relates a specific property of materials to their structural characteristics. For the sake of QSPR modeling a dataset of 24 structurally different surfactants was created through the measurement of contact angles (as the most important surfactant characteristic in the wettability alteration process). Contact angle measurement was carried out through imaging a drop of n-decane as the model oil resting on a carbonate rock which has spent 2 days immersed in surfactant solution For this dataset a linear QSPR model of oil contact angle on carbonate rocks was derived using genetic algorithm based on multi-linear regression (GA-MLR) and verified by internal and external validation metrics. From a descriptive point of view, descriptors of the proposed model have a mechanistic interpretation and give an insight to the desired structural features enhancing wettability alteration ability of surfactants.

Fallah Fini, Mojtaba published the artcileExperimental and QSPR Studies on the Effect of Ionic Surfactants on n-Decane-Water Interfacial Tension, COA of Formula: C19H34ClN, the publication is Journal of Surfactants and Detergents (2012), 15(4), 477-484, database is CAplus.

A quant. structure property relationship approach was performed to find the relation between the surfactant structure and its effect on water-oil interfacial tension. As a result, a new database has been developed measuring the interfacial tension between n-decane as the model oil and different aqueous solutions of some ionic compounds In spite of other reports we selected surfactants by a scientific method that covers all structural information. Twenty four different compounds were selected by the principal component anal. method and their interfacial tensions were measured at their critical micelle concentrations The geometrical optimization of surfactants was performed at the B3LYP/6-311G** level and quantum chem. and structural descriptors were calculated using relevant computer software programs. The best fitted descriptors were selected using the variable selection of the genetic algorithm (GA-MLR). The predictive test was performed for an external prediction set of 6 compounds, chosen out of 24 compounds The resulted GA-MLR model can reasonably predict the interfacial tension using only three selected descriptors. The deviation between predicted and measured values was found to be <7%.

Schlapbach, Achim published the artcileN-aryl-piperidine-4-carboxamides as a novel class of potent inhibitors of MALT1 proteolytic activity, Formula: C6H3ClFNO2, the publication is Bioorganic & Medicinal Chemistry Letters (2018), 28(12), 2153-2158, database is CAplus and MEDLINE.

Starting from a weak screening hit, potent and selective inhibitors of the MALT1 protease function were elaborated. Advanced compounds displayed high potency in biochem. and cellular assays. Compounds showed activity in a mechanistic Jurkat T cell activation assay as well as in the B-cell lymphoma line OCI-Ly3, which suggests potential use of MALT1 inhibitors in the treatment of autoimmune diseases as well as B-cell lymphomas with a dysregulated NF-κB pathway. Initially, rat pharmacokinetic properties of this compound series were dominated by very high clearance which could be linked to amide cleavage. Using a rat hepatocyte assay a good in vitro-in vivo correlation could be established which led to the identification of compounds with improved PK properties.
