Improved BM212 MmpL3 Inhibitor Analogue Shows Efficacy in Acute Murine Model of Tuberculosis Infection

1,5-Diphenyl pyrroles were previously identified as a class of compounds endowed with high in vitro efficacy against M. tuberculosis. To improve the physical chemical properties and drug-like parameters of this class of compounds, a medicinal chemistry effort was undertaken. By selecting the optimal substitution patterns for the phenyl rings at N1 and C5 and by replacing the thiomorpholine moiety with a morpholine one, a new series of compounds was produced. The replacement of the sulfur with oxygen gave compounds with lower lipophilicity and improved in vitro microsomal stability. Moreover, since the parent compound of this family has been shown to target MmpL3, mycobacterial mutants resistant to two compounds have been isolated and characterized by sequencing the mmpL3 gene; all the mutants showed point mutations in this gene. The best compound identified to date was progressed to dose-response studies in an acute murine TB infection model. The resulting ED99 of 49 mg/Kg is within the range of commonly employed tuberculosis drugs, demonstrating the potential of this chemical series. The in vitro and in vivo target validation evidence presented here adds further weight to MmpL3 as a druggable target of interest for anti-tubercular drug discovery.

Synthesis and biological evaluation of new Mannich and Schiff bases containing 1,2,4-triazole and 1,3,4-oxadiazole nucleus

5-(Pyridine-3-yl)-1,3,4-oxadiazole-2-thiole 2, obtaining starting from nicotinic acid hydrazide were converted to the corresponding Mannich bases (3a-c) by the reaction with several heterocyclic amines in the presence of formaldehyde. 1,2,4-Triazole-3-thiole, (4) prepared from 1,3,4-oxadiazole-2-thiole (2) was converted to the corresponding Mannich bases (5a-e) by several steps. The synthesis of Schiff bases (6a-d) was performed from the reaction of the corresponding triazol-3-thioles with various aromatic aldehydes. The treatment of Schiff bases containing 1,2,4-triazoles 6c and 6d with morpholine or thiomorpholine generated the corresponding Mannich bases 7a, b and 8a, b. The synthesized compounds were screened for their antimicrobial, antilipase, and antiurease activities. Some of them were found to possess good-moderate antimicrobial, antiurease, and/or antilipase activity.

Structure-reactivity correlations for complex formation reactions between square-planar metal centers and thioethers

Kinetics for complex formation between Pd(H2O)(4)(2+) and thioethers of largely varying electronic and steric properties, viz. MeSCH(2)COOH, (n-Pr)(2)S, EtSCH(2)CH(2)OH, S(CH2CH2CH2OH)(2), S(CH2CH2OH)(2), EtSCH(2)COOH, S(CH2COOH)(2), S(CH2CH2COOH)(2), (i-Pr)(2)S, (s-Bu)(2)S, (t-Bu)(2)S, and protonated thiomorpholine, S(C2H4)(2)NH2+, has been studied by use of stopped-flow spectrophotometry in an acidic aqueous medium. Second-order rate constants k(1)(298) are 1.61 x 10(4), 8.0 x 10(4), 3.79 x 10(4), 3.69 x 10(4), 2.21 x 10(4), 1.84 x 10(4), 1.91 x 10(3), 1.34 x 10(4), 1.52 x 10(4), 7.75 x 10(3), 900, and 5.2 x 10(3) M(-1) s(-1), respectively. The reactivity toward Pd(H2O)(4)(2+) of all thioethers studied so far can be described as a function of their sigma-donor properties as expressed by the sum of the Taft constants, Sigma sigma*, and their steric requirements as defined by cone angles, theta, by use of the equation: log k(1) = (9.9 +/- 0.3) – (0.67 +/- 0.05)Sigma sigma* – (0.059 +/- 0.003)theta. Similarly, second-order rate constants k(298) reported previously for reactions between thioethers and Pd(dien)H2O2+ and Pt(dienBr+ are described by log k(298) = (10.5 +/- 0.6) – 0.67 Sigma sigma* – (0.081 +/- 0.006)theta and log k(298) = (4.6 +/- 0.6) – 0.72 Sigma sigma* – (0.080 +/- 0.006)theta, respectively. Hence, the reactivity trends of thioethers toward square-planar complexes can be given a general interpretation in terms of intrinsic, electronic, and steric parameters, by use of log k = gamma + alpha Sigma sigma* + beta theta. Large variations in both electronic and steric properties of the entering ligands indicate that there is no ”duality behavior” in the reactions of thioethers with square-planar metal centers, as claimed in previous literature. No steric threshold is observed for these sterically unhindered systems. There is a rough compensation effect between Delta H-1 double dagger and Delta S-1 double dagger, i.e. a smaller Delta H-1 double dagger is usually accompanied by a larger negative Delta S-1 double dagger, indicating that all thioethers react via the same mechanism. It appears that the much lower reactivity observed for the highly branched (t-Bu)(2)S is primarily caused by a high activation enthalpy. Volumes of activation have been determined for a series of thioethers with a constant cone angle, viz. EtSCH(2)COOH, S(CH2COOH)(2), and S(CH2CH2COOH)(2) through high-pressure stopped-flow measurements. Values of Delta V-1 double dagger are -7.9 +/- 0.5, -8.1 +/- 0.4, and -7.6 +/- 0.3 cm(3) mol(-1), respectively. These values together with that for Et(2)S (-8.7 +/- 0.1 cm(3) mol(-1)) determined previously shows that variation of electronic properties, steric factors being kept constant, change the reactivity markedly, but have no observable influence on the activation volumes. Stability constants beta(1) for five palladium thioether complexes derived as the ratio between rate constants for forward and reverse reactions vary between (1.2 +/- 0.3) x 10(4) and (3.2 +/- 0. 7) x 10(4) M(-1).

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 589-87-7. Category: thiomorpholine.

Evaluation and optimization of synthetic routes from dihydroartemisinin to the alkylamino-artemisinins artemiside and artemisone: A test of N-glycosylation methodologies on a lipophilic peroxide

10-Alkylamino-artemisinins including artemiside and artemisone display enhanced activities against malaria. Earlier, dihydroartemisinin (DHA) TMS ether was converted by trimethylsilyl bromide into the 10-beta-bromide that with amine nucleophiles provided the amino-artemisinins. In an attempt to develop more economic approaches, direct N-glycosylation of DHA was examined but 2-deoxyartemisinin was invariably obtained. However, hydroxyl group activation by conversion into the 10 beta-halide in non-polar solvents with anhydrous HCl and Group I and II metal halides, oxalyl chloride or thionyl chloride with catalytic DMSO, and oxalyl bromide did succeed. The beta-halides were converted in situ by thiomorpholine into artemiside, and by thiomorpholine-1,1-dioxide into artemisone respectively in scalable reactions. Hydrogen peroxide-acetonitrile or the urea-hydrogen peroxide complex efficiently oxidized the sulfide artemiside to the sulfone artemisone. Overall, a generalized approach to 10-alkylamino-artemisinins is now available. (C) 2018 Elsevier Ltd. All rights reserved.

Hydrogen-bond basicity pK(HB) scale of secondary amines

Using 4-fluorophenol as a reference hydrogen-bond donor, equilibrium constants K for the formation of 1 : 1 hydrogen-bonded complexes have been obtained by FTIR spectrometry for 33 secondary amines in CCl4 and/or C2Cl4 at 298 K. A spectroscopic scale of hydrogen-bond basicity is constructed from the IR frequency shift Av(OH) of methanol hydrogen-bonded to secondary amines. The comparison of the pK(HB) (log K), Deltav(OH), and pK(a) scales points to the sensitivity of pK(HB) to steric effects, and of Deltav(OH) to the p character of the nitrogen lone pair. The pKHB scale of secondary amines extends from 2.59 for pyrrolidine to -0.45 for (Me3Si)(2)NH. The main effects explaining the pK(HB) variations are (i) the opposite polarizability and steric effects in alkylamines, (ii) field-inductive effects (e.g N drop CCH2NHMe), (iii) intramolecular hydrogen bonding, e.g. in (MeOCH2CH2)(2)NH, and (iv) the ring size giving the order: pyrrolidine = azetidine > piperidine > 2-methylaziridine > azepane. IR spectra show the attachment of 4-fluorophenol to the nitrile nitrogen of N drop CCH2NHMe and N drop CCH2CH2NHMe, to the oxygen of morpholine and (MeOCH2CH2)(2)NH, and to the sulfur of thiomorpholine and thiazolidine, in addition to attachment to the amino nitrogen. The correlation of pK(HB) with the minimum electrostatic potential on the nitrogen lone pair is used for unravelling the basicity of each nitrogen of 1-methyl-1,4-diazepane.

Donor Abilities of Heterocyclic Neutral Lewis Bases in a Nickel(II) Salicylaldehyde 4-Phenylthiosemicarbazonato Coordination Environment

Eight mononuclear [Ni(sal 4-Phtsc)center dot D] thiosemicarbazonato complexes [sal4-Phtsc = salicylaldehyde 4-phenylthiosemicarbazonato ligand; D = imidazole (1), methylimidazole (2), pyridine (3), 4-aminopyridine (4), 4-methylpyridine (6), morpholine (7), thiomorpholine (8), 2-aminophenol (9)] and one dinuclear {[Ni(sal 4-Phtsc)](2)center dot D} center dot 2DMSO [D = 4,4′-bipyridine (5)] complex have been prepared by adding the corresponding Lewis base to the methanol suspension of the parent complex [Ni(sal 4-Phtsc)(H(2)sal4-Phtsc)]center dot CH3OH. The exchange of the neutral salicylaldehyde 4-phenylthiosemicarbazone (H(2)sal4-Phtsc) ligand in the parent complex for the appropriate Lewis base has been confirmed by IR spectroscopy and powder X-ray diffraction (PXRD) in the solid state. The single-crystal X-ray diffraction of seven complexes 1 and 3-8 confirmed the formation of the complexes with the Ni-II ion, coordinated through O,N,S-donor atoms from the dibasic salicylaldehyde 4-phenylthiosemicarbazonato ligand and endocyclic N-donor atom from the neutral ligand D in the form of a distorted square-planar coordination. NMR spectroscopy in DMF or DMSO and quantum mechanical calculations have been performed in order to explain and compare the stability of the complexes in solution, depending on the polarity of solvents in the context of donor properties and the nucleophilicity of the heterocyclic Lewis base. The single-crystal X-ray data enables a comparison with calculated standard Gibbs energies of binding in the context of crystal packing forces, leading to a general conclusion that the stability of the mononuclear complexes results in the formation of more stable hydrogen-bonded cyclic dimers as a crystal packing pattern.
