Helicobacter pylori is a Gram-negative bacterium that colonizes the gut of over 50% of the worlds population. It is responsible for most peptic ulcers and is an important risk factor for gastric cancer. Antibiotic treatment for H. pylori infections is challenging as drug resistance has developed to antibiotics with traditional mechanisms of action. H. pylori uses an unusual pathway for menaquinone biosynthesis with 5?-methylthioadenosine/S-adenosylhomocysteine nucleosidase (MTAN) catalyzing an essential step. We validated MTAN as a target with a transition-state analogue of the enzyme [Wang, S.; Haapalainen, A. M.; Yan, F.; et al. Biochemistry 2012, 51, 6892-6894]. MTAN inhibitors will only be useful drug candidates if they can both include tight binding to the MTAN target and have the ability to penetrate the complex cell membrane found in Gram-negative H. pylori. Here we explore structural scaffolds for MTAN inhibition and for growth inhibition of cultured H. pylori. Sixteen analogues reported here are transition-state analogues of H. pylori MTAN with dissociation constants of 50 pM or below. Ten of these prevent growth of the H. pylori with IC90 values below 0.01 mug/mL. These remarkable compounds meet the criteria for potent inhibition and cell penetration. As a consequence, 10 new H. pylori antibiotic candidates are identified, all of which prevent H. pylori growth at concentrations 16-2000-fold lower than the five antibiotics, amoxicillin, metronidazole, levofloxacin, tetracyclin, and clarithromycin, commonly used to treat H. pylori infections. X-ray crystal structures of MTAN cocrystallized with several inhibitors show them to bind in the active site making interactions consistent with transition-state analogues.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. Formula: C11H21NO4, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 108149-65-1, in my other articles.

The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 102029-44-7, (R)-4-Benzyl-2-oxazolidinone, introducing its new discovery.

The synthesis of the chiral core structure of the lissoclimide class of anti-tumour agents containing three rings, including a chiral succinimide subunit and an exocyclic double bond, has been investigated. The compound 7 was obtained, without the use of any protecting groups for the alcohol at C-12, via an asymmetric boron-mediated aldol addition as the key step to install the chiral centres of the rare succinimido methanol moiety. This was followed by a sequence of lactonisation, microwave-assisted amidation and imidation reactions.

(Matrix Presented) The highly stereoselective synthesis of beta-amino acids via the chiral 4-phenyloxazolidinone-controlled linear N-acyliminium ion reaction has been achieved by employing chiral N,O-acetal TMS ethers. In addition, the mechanism of the excellent stereochemical outcome has been elucidated. The oxazolidinone auxiliary plays a dual role in stereocontrol: the E/Z geometry control of the N-acyliminium ion induced by an initial stereoselective amide reduction, leading to the chiral N,O-acetal TMS ether, and face control of the nucleophile attack in the N-acyliminium ion reaction.

Fly ash contains varying amounts of transition metals depending on the fuel, combustion and also downstream emission control process. As certain transition metal ions are known to catalyze solvent degradation, the impact of fly ash is an important consideration for a post-combustion CO2 capture process. Here, five different fly ashes were screened with a representative carbon dioxide loaded aqueous monoethanolamine solution. The addition of fly ash has been found to impact oxidative degradation and product distribution significantly. Eight products have been identified and quantified by LC-TOF method. Some of the new products identified here contain a secondary amine group that could potentially nitrosate further. The rates of formation of these products were determined and found much higher with fly ash compared to MEA alone.

Biphenylacetic acid (5) was identified through a library screen as an inhibitor of the prostaglandin D2 receptor DP2 (CRTH2). Optimization for potency and pharmacokinetic properties led to a series of selective CRTH2 antagonists. Compounds demonstrated potency in a human DP2 binding assay and a human whole blood eosinophil shape change assay, as well as good oral bioavailability in rat and dog, and efficacy in a mouse model of allergic rhinitis following oral dosing.

Remote asymmetric induction by the vinylogous Mukaiyama aldol reaction using the acetate-type vinylketene silyl N,O-acetal possessing a chiral auxiliary has been achieved. The silyl N,O-acetal derived from crotonate and L-valine afforded the O-silylated 5R- and 5S-adducts selectively by treatment with SnCl4 and BF3·OEt2, respectively. The SnCl4-mediated isomerization of silyl dienol ether was found, and the resulting major isomer showed high reactivity to give gamma-adduct in high stereoselectivity.
