Synthesis, nicotinic acetylcholine receptor binding, antinociceptive and seizure properties of methyllycaconitine analogs

A series of methyllycaconitine (1a, MLA) analogs was synthesized where the (S)-2-methylsuccinimidobenzoyl group in MLA was replaced with a (R)-2-methyl, 2,2-dimethyl-, 2,3-dimethyl, 2-phenyl-, and 2-cyclohexylsuccinimidobenzoyl (1b-f) group. The analogs 1b-f were evaluated for their inhibition of [125I]iodo-MLA binding at rat brain alpha7 nicotinic acetylcholine receptors (nAChR). In order to determine selectivity, MLA and the analogs 1b-f were evaluated for inhibition of binding to rat brain alpha,beta nAChR using [3H]epibatidine. At the alpha7 nAChR, MLA showed a Ki value of 0.87 nM, analogs 1b-e possessed Ki values of 1.67-2.16 nM, and 1f showed a Ki value of 26.8 nM. Surprisingly, the analog 1e containing the large phenyl substituent (Ki = 1.67 nM) possessed the highest affinity. None of the compounds possessed appreciable affinity for alpha,beta nAChRs. MLA antagonized nicotine-induced seizures with an AD50 = 2 mg/kg. None of the MLA analogs were as potent as MLA in this assay. MLA and all of the MLA analogs, with the exception of 1b, antagonized nicotine’s antinociceptive effects in the tail-flick assay. Compound 1c (Ki = 1.78 nM at alpha7 nAChR) with an AD50 value of 1.8 mg/kg was 6.7 times more potent than MLA (AD50 = 12 mg/kg) in antagonizing nicotine’s antinociceptive effects but was 5-fold less potent than MLA in blocking nicotine-induced seizures. Since MLA has been reported to show neuroprotection against beta-amyloid1-42, these new analogs which have high alpha7 nAChR affinity and good selectivity relative to alpha,beta nAChRs will be useful biological tools for studying the effects of alpha7 nAChR antagonist and neuroprotection.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. COA of Formula: C6H8O3, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 17347-61-4, in my other articles.

Towards small molecule inhibitors of mono-ADP-ribosyltransferases

Protein ADP-ribosylation is a post-translational modification involved in DNA repair, protein degradation, transcription regulation, and epigenetic events. Intracellular ADP-ribosylation is catalyzed predominantly by ADP-ribosyltransferases with diphtheria toxin homology (ARTDs). The most prominent member of the ARTD family, poly(ADP-ribose) polymerase-1 (ARTD1/PARP1) has been a target for cancer drug development for decades. Current PARP inhibitors are generally non-selective, and inhibit the mono-ADP-ribosyltransferases with low potency. Here we describe the synthesis of acylated amino benzamides and screening against the mono-ADP-ribosyltransferases ARTD7/PARP15, ARTD8/PARP14, ARTD10/PARP10, and the poly-ADP-ribosyltransferase ARTD1/PARP1. The most potent compound inhibits ARTD10 with sub-micromolar IC50.

Impact of freeze-drying and subsequent storage on milk metabolites based on 1H NMR and UHPLC-QToF/MS

This study is the first to investigate the effect of freeze-drying on raw milk metabolites using untargeted metabolomics. To detect as many metabolites as possible in the liquid fractions, a multiplatform metabolomics approach was implemented using both NMR and MS-based techniques. The chemical fingerprint of freeze-dried milk powder was monitored during storage at three temperatures (room temperature, 4 C, ?20 C) for up to 224 days. This study demonstrated that freeze-drying was an efficient means of drying milk resulting in only minor changes to the metabolites. With respect to storage, freeze-dried milk powders stored at 4 C and ?20 C exhibited a stable metabolome while samples stored at 20 C resulted in a clear change. During ambient storage, the concentrations of orotic acid, riboflavin and acetyl-carbohydrate reduced while those of fatty acids, threonic acid and uridine increased. The results from this study provide the foundation for experiment design and marker selection for further studies on milk metabolomics.

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 637-64-9 is helpful to your research. 637-64-9
