New research progress on 589-87-7 in 2021. Chemical research careers are more diverse than they might first appear, as there are many different reasons to conduct research and many possible environments. 589-87-7, Name is 1-Bromo-4-iodobenzene, molecular formurla is C6H4BrI. In a document, author is Duarte, CD, introducing its new discovery. Safety of 1-Bromo-4-iodobenzene.

We describe herein the structural optimization of new piperamide analogues, designed from two natural prototypes, piperine 1 and piper-dardine 2, obtained from Piper tuberculatum Jacq. (Piperaceae). Molecular modeling studies using semiempirical AMI method were made in order to establish rational modifications to optimize them by molecular simplification. The targeted compounds (10) and (11) were respectively obtained using benzaldehyde (12) and para-anisaldehyde (13) as starting materials. H-1 NMR spectra showed that the target compounds were diastereoselectively obtained as the (E)-isomer, the same geometry of the natural prototypes. These new synthetic amides presented significant hypotensive effects in cardiovascular essays using in vivo methodologies. Compound 11 (N-[5-(4′-methoxyphenyl)2(E)-pentenoyl]thiomorpholine) showed a potency 10,000 times greater than its prototype 5, evidencing an optimization of the molecular architecture for this class of hypotensive drug candidates.

Researchers are common within chemical engineering and are often tasked with creating and developing new chemical techniques, frequently combining other advanced and emerging scientific areas. In an article, author is Marvadi, Sandeep Kumar, once mentioned the application of 589-87-7, Name is 1-Bromo-4-iodobenzene, molecular formula is C6H4BrI, molecular weight is 282.9044, MDL number is MFCD00001051, category is thiomorpholine. Now introduce a scientific discovery about this category, Quality Control of 1-Bromo-4-iodobenzene.

We, herein, describe the synthesis of a series of novel aryl tethered 7,8-dihydroquinolin-5(6H)-ylidenehydrazinecarbothioamides 4a-v, which showed in vitro and in vivo antimycobacterial activity against Mycobacterium tuberculosis (Mtb) H37Rv. The intermediates dihydro-6H-quinolin-5-ones 3a-v were synthesized from beta-enaminones, reacting with cyclochexane-1,3-dione/5,5-dimethylcyclohexane-1,3-dione and ammonium acetate using a modified Bohlmann-Rahtz reaction conditions. They were further reacted with thiosemicarbazide to give the respective hydrazine carbothioamides 4a-v. All the new analogues 4a-v, were characterized by their NMR and mass spectral data analysis. Among the twenty-two compounds screened for in vitro antimycobacterial activity against Mycobacterium tuberculosis H37Rv (ATCC27294), two compounds, 4e and 4j, exhibited the highest inhibition with an MIC of 0.39 mu g/mL. Compounds 4a, 4g, and 4k were found to inhibit Mtb at an MIC of 0.78 mu g/mL. Hydrazinecarbothioamides 4a-k, exhibited enhanced activity than dihydroquinolinones 3a-k. The observed increase in potency provides a clear evidence that hydrazinecarbothioamide is a potential pharmacophore, collectively imparting synergistic effect in enhancing antitubercular activity of the dihydroquinolinone core. The in vivo (Zebra fish) antimycobacterial screening of the in vitro active molecules led to the identification of a hit compound, 4j, with significant activity in the Mtb nutrient starvation model (2.2-fold reduction). Docking studies of 4j showed a hydrogen bond with the P156 residue of the protein.

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).

In an article, author is Li, YX, once mentioned the application of 589-87-7, Name is 1-Bromo-4-iodobenzene, molecular formula is C6H4BrI, molecular weight is 282.9044, MDL number is MFCD00001051, category is thiomorpholine. Now introduce a scientific discovery about this category, Application of 589-87-7.

A chelating ligand, 2,6-bis(thiomorpholinomethyl)pyridine (L), was synthesised. Its palladium(II), copper(II) and nickel(II) complexes of the formula ML(NO3)(2), (M = Pd, Cu and Ni), were prepared and characterised. The molecular structures of the three complexes were determined by X-ray diffraction. In all the compounds prepared the ligand acts in a tridentate fashion using its three N atoms while the two S atoms remain free. The Pd complex possesses a distorted square planar coordination geometry with one of the two nitrate groups coordinating as a unidentate ligand and the other ionic. The Pd-N(pyridine) bond length is 1.857(4) Angstrom, which is believed to be the shortest Pd-N separation ever observed. In the Cu complex, the copper atom is five-coordinated in a distorted square planar arrangement with the two nitrate groups acting as unidentate ligands and occupying the apex and one equatorial position. The Ni complex has a distorted octahedral coordination sphere; one nitrate group behaves in a chelating fashion and the other unidentate. (C) 1998 Elsevier Science S.A. All rights reserved.
