Discovery of 4-alkoxy-6-methylpicolinamide negative allosteric modulators of metabotropic glutamate receptor subtype 5

This letter describes the further chemical optimization of VU0424238 (auglurant), an mGlu5 NAM clinical candidate that failed in non-human primate (NHP) 28 day toxicology due to accumulation of a species-specific aldehyde oxidase (AO) metabolite of the pyrimidine head group. Here, we excised the pyrimidine moiety, identified the minimum pharmacophore, and then developed a new series of saturated ether head groups that ablated any AO contribution to metabolism. Putative back-up compounds in this novel series provided increased sp3 character, uniform CYP450-mediated metabolism across species, good functional potency and high CNS penetration. Key to the optimization was a combination of matrix and iterative libraries that allowed rapid surveillance of multiple domains of the allosteric ligand.

Comparative study of batch and continuous multi-stage fixed-bed tower (MFBT) bioreactor during wine-making using freeze-dried immobilized cells

A freeze-dried immobilized biocatalyst produced by immobilization of Saccharomyces cerevisiae AXAZ-1 yeast cells on gluten pellets and subsequent freeze-drying was used in a multistage fixed-bed tower (MFBT) bioreactor for batch and continuous wine-making. The MFBT bioreactor resulted in higher alcohol productivity compared to fermentations carried out in a packed bed (PB) bioreactor and showed an important operational stability and no decrease in activity, even at low fermentation temperature (5 C) and after storage for 6 months at 4 C. The production of amyl alcohols proved to be temperature dependent and was significantly reduced at low temperatures. Re-activation of the freeze-dried immobilized cells after storage for 6 months resulted in further decreased content of amyl alcohols. The SPME GC/MS analysis of volatile compounds revealed no significant differences in the wines produced by MFBT and PB bioreactors, while the preliminary sensory evaluation ascertained the overall improved quality of the produced wines. Potential industrial application of MFBT bioreactor is also assessed and discussed.

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.Product Details of 2081-44-9, you can also check out more blogs about2081-44-9

Synthesis of new poly(arylamine)s (aryl = oligo-p-phenyl or pyridyl) by organometallic polycondensation and chemical properties of the polymers

A series of poly(arylamine)s formulated as [-(Ar)mNR-] n(Ar = p-phenylene or pyridine-2,5-diyl; m = 2-4; R = H or alkyl) were prepared. Ni- or Pd-promoted dehalogenative polycondensation of the corresponding BOC- (tert-butoxycarbonyl-) substituted dibromo monomers afforded poly(oligo-p-phenyleneamine)s, [-(p-C6H4) mN(BOC)-]n (m = 2-4). Deprotection of the BOC group of the polymer at 200 C gave [-(p-C6H4NH-]n (m = 2-4). The polymer behaved as an intermediate polymer between poly(aniline) PAn and poly(p-phenylene) PPP. For example, [-(p-C6H4NH-] n, P(DPA), showed two oxidation peaks at around 0.3 and 0.65 V vs Ag+/Ag with equal intensity in its CV (cyclic voltammetry) chart, similar to PAn; in contrast, the CV chart of [-(p-C6H 4)4NH-]n exhibited a main oxidation peak at 0.60 V vs Ag+/Ag, similar to PPP. ESR data of iodine-doped polymers supported the formation of radical species in oxidation of the polymer. The polymers were photoluminescent and gave quantum yields of 12-46%. Polymers with the pyridine unit formed metal complexes with MX2 (M = Cu, Ni, Co), and CD (circular dichroism) spectra of the metal complexes of the pyridine polymer having chiral side chains suggested formation of a helical structure by the metal complexation.

A Novel Method for Stereoselective Glucuronidation

A variety of hydroxylic aglycones can be glucuronidated directly with methyl 2,3,4-tri-O-acetylglucopyranuronate (4a), activated with trimethylsilyl trifluoromethanesulfonate (Me3Si-OTf).This reaction provides mostly beta, and sometimes alpha, glucopyranosiduronic acid derivatives (referred to as glucuronides) rapidly and at low temperatures.The epimeric ratio depends on the relative aglycone nucleophilicity vs. its tendency to form a stabilized carbocation by the formal loss of -OH.Glucuronides of various aromatic and aliphatic aglycones as well as those of a number of cyanohydrins were prepared.The characteristic features of the 1H NMR spectra of alpha and beta derivatives which are presented are useful in the assignment of product stereochemistry and determination of epimeric ratios in those reactions where mixtures are obtained.
