Discovery of [1,2,4]Triazole Derivatives as New Metallo-beta-Lactamase Inhibitors

The emergence and spread of metallo-beta-lactamase (MBL)-mediated resistance to beta-lactam antibacterials has already threatened the global public health. A clinically useful MBL inhibitor that can reverse beta-lactam resistance has not been established yet. We here report a series of [1,2,4]triazole derivatives and analogs, which displayed inhibition to the clinically relevant subclass B1 (Verona integron-encoded MBL-2) VIM-2. 3-(4-Bromophenyl)-6,7-dihydro-5H-[1,2,4]triazolo [3,4-b][1,3]thiazine (5l) manifested the most potent inhibition with an IC50 (half-maximal inhibitory concentration) value of 38.36 mu M. Investigations of 5l against other B1 MBLs and the serine beta-lactamases (SBLs) revealed the selectivity to VIM-2. Molecular docking analyses suggested that 5l bound to the VIM-2 active site via the triazole involving zinc coordination and made hydrophobic interactions with the residues Phe61 and Tyr67 on the flexible L1 loop. This work provided new triazole-based MBL inhibitors and may aid efforts to develop new types of inhibitors combating MBL-mediated resistance.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 26978-64-3 is helpful to your research. Name: 4-Hydroxybutane-1-sulfonic acid.

Synthesis and Intramolecular Cyclization of N-acyl- and N-allyl-N ‘-(2-oxo-1,2-dihydro-pyridin-3-yl)thiourea

The reaction of 3-amino-4,6-dimethylpyridin-2(1H)-one and 3-amino-4-phenylpyridin-2-one with acyl isothiocyanates (benzoyl-, 4-bromobenzoyl-, and methacryloyl isothiocyanates) and with allyl isothiocyanate has been studied. The N-carbamothioyl methacrylamides and N-allylthioureas obtained undergo intramolecular heterocyclization reactions to give the corresponding 1,3-thiazin-4-one and 1,3-thiazoline derivatives. It was found that the starting 3-amino-4,6-dimethylpyridin-2(1H)-one shows antiradical activity but the synthesized thioureas do not.

Synthesis of 5,6-dihydro-4H-1,3-thiazine containing peptide mimics from N-(3-hydroxypropyl)thioamides and epimerization studies

The first synthesis of 1,3-thiazine fused peptide mimics is described from N-(3-hydroxypropyl)thioamides under MsCl/NEt3 conditions. The method is amenable to oligopeptidomimics with polar and apolar side chains. Substantial epimerization occurs at chiral C(2) exo methines in non-Pro fused mimics even under neutral conditions. H-1 NMR and crystal structure analyses indicate that the Thi analogues primarily associate with each other through intermolecular hydrogen bonds, involving the nitrogen of 1,3-thiazine and the N-H of the fused residue, which may be the basis for enamination-racemization process in these peptide mimics.

Synthesis, characterization and in vivo evaluation of [Zn-62]-benzo-delta-sultam complex as a possible pet imaging agent

Objective The development of a new tracer based on the cyclic sulfonamides (sultams) was investigated. Methods 3-(Methoxy-phenyl-methyl)-1,6-dimethyl-1H benzo[c][1,2] thiazine 2,2-dioxide (benzo-delta-sultam) was synthesized and characterized by elemental analysis, FT-IR spectroscopy and single crystal X-ray structure determination. The prepared cyclic sulfonamide was labeled with non-commercial Zn-62 radioisotope for fast in vivo targeting and Coincidence imaging purposes (radiochemical purity 97 % ITLC, 96 % HPLC, specific activity 20-23 GBq/mmol). In vivo biodistribution of the final complex was investigated in Sprague Dawley (R) rats bearing fibro sarcoma tumor after 2, 4 and 8 h post injection and compared with free Zn+2 cation. Results Using instant paper chromatography method, the physicochemical properties of labeled compounds were found sufficiently stable in organic phases, e. g. a human serum, to be reliably used in bioapplications. Conclusions The complex exhibited a rapid as well as high tumor uptake (tumor to blood ratio 4.38 and tumor to muscle ratio 9.63) resulting in an efficient tumor targeting agent.

A new series of thiazolyl pyrazoline derivatives linked to benzo[1,3]dioxole moiety: Synthesis and evaluation of antimicrobial and anti-proliferative activities

2-(5-(Benzo[d][1,3]dioxol-5-yl)-3-(naphthalen-1-yl)-4,5-dihydro-1H-pyrazol-1-yl)-4-(4-substituted phenyl)thiazole (7) and thiazole derivatives (9) were synthesized via reaction of 4,5-dihydro-1H-pyrazoles (5a,b) with substituted phenacyl bromide and a number of alpha-halo-compounds respectively. Also, (E)-2-(5-(benzo[d][1,3]dioxol-5-yl)-3-(naphthalen-1-yl)-4,5 dihydro-1H-pyrazol-1-yl)-4-methyl-5-(substituted phenyldiazenyl)thiazole (11) were prepared through reactions of carbothioamide (5a,b) with hydrazonoyl halides. In addition, thioamides (5a-b) were used as starting materials for preparation of thiazoles (12a-b) and benzylidene thiazoles (13a-b). Most of synthesized compounds show interesting biological properties as antimicrobial and antiproliferative activities, the results of minimum inhibitory concentration showed that pyrazole derivative 7c (MIC: 0.23 mg/mL) showed better results when compared with 11c and 12a (MIC: 0.1-0.125 mg/mL) as obtained from their MIC values. On the other hand, 2-(5-(benzo[d][1,3]dioxol-5-yl)-3-(naphthalen-2-yl)-4,5-dihydro-1H-pyrazol-1-yl)-4-(4-chlorophenyl) thiazole (7c) can be considered as the most promising anti-proliferative agent against HCT-116 cancer cells owing to its notable inhibitory effect on HCT-116 cells with an IC50 value of 6.19 mu M.

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 139-65-1. Recommanded Product: 139-65-1.
