Pyrimidines

The systematic study of pyrimidines began in 1884 with Pinner, who synthesized derivatives by condensing ethyl acetoacetate with amidines. Pinner first proposed the name “pyrimidin” in 1885. 65-86-1, formula is C5H4N2O4, Name is 2,6-Dioxo-1,2,3,6-tetrahydropyrimidine-4-carboxylic acid. The parent compound was first prepared by Gabriel and Colman in 1900, by conversion of barbituric acid to 2,4,6-trichloropyrimidine followed by reduction using zinc dust in hot water.

Pulletikurti, Sunil;Yadav, Mahipal;Springsteen, Greg;Krishnamurthy, Ramanarayanan research published 《 Prebiotic synthesis of α-amino acids and orotate from α-ketoacids potentiates transition to extant metabolic pathways》, the research content is summarized as follows. The Strecker reaction of aldehydes is the pre-eminent pathway to explain the prebiotic origins of α-amino acids. However, biol. employs transamination of α-ketoacids to synthesize amino acids which are then transformed to nucleobases, implying an evolutionary switch-abiotically or biotically-of a prebiotic pathway involving the Strecker reaction into today′s biosynthetic pathways. α-Ketoacids react with cyanide and ammonia sources to form the corresponding α-amino acids through the Bucherer-Bergs pathway. An efficient prebiotic transformation of oxaloacetate to aspartate via N-carbamoyl aspartate enables the simultaneous formation of dihydroorotate, paralleling the biochem. synthesis of orotate as the precursor to pyrimidine nucleobases. Glyoxylate forms both glycine and orotate and reacts with malonate and urea to form aspartate and dihydroorotate. These results, along with the previously demonstrated protometabolic analogs of the Krebs cycle, suggest that there can be a natural emergence of congruent forerunners of biol. pathways with the potential for seamless transition from prebiotic chem. to modern metabolism

N-Monoalkylation of primary amines is attained with a 1:1 aldehyde to amine ratio, whereas excess of the aldehyde (≥2:1) allows second alkylation, giving rise to tertiary amines. Reductive N-alkylation of α-amino acids proceeds without racemization; the resulting products, containing a CC bond or N₃ group, are suitable for click chem. This reaction thus offers advantages over the traditional methods (borohydride reduction or catalytic hydrogenation) in terms of efficiency and chemoselectivity. Solubility of some of the reacting partners appears to be the only limitation. The byproducts generated by the workup with aqueous NaHCO₃ (i.e., NaCl and silica) are environmentally benign. As a greener alternative, DMA can be employed as a catalyst instead of DMF.

Popkov, Vasily A.;Zharikova, Anastasia A.;Demchenko, Evgenia A.;Andrianova, Nadezda V.;Zorov, Dmitry B.;Plotnikov, Egor Y. research published 《 Gut Microbiota as a Source of Uremic Toxins》, the research content is summarized as follows. Uremic retention solutes are the compounds that accumulate in the blood when kidney excretory function is impaired. Some of these compounds are toxic at high concentrations and are usually known as “uremic toxins”. The cumulative detrimental effect of uremic toxins results in numerous health problems and eventually mortality during acute or chronic uremia, especially in end-stage renal disease. More than 100 different solutes increase during uremia; however, the exact origin for most of them is still debatable. There are three main sources for such compounds: exogenous ones are consumed with food, whereas endogenous ones are produced by the host metabolism or by symbiotic microbiota metabolism In this article, we identify uremic retention solutes presumably of gut microbiota origin. We used database anal. to obtain data on the enzymic reactions in bacteria and human organisms that potentially yield uremic retention solutes and hence to determine what toxins could be synthesized in bacteria residing in the human gut. We selected biochem. pathways resulting in uremic retention solutes synthesis related to specific bacterial strains and revealed links between toxin concentration in uremia and the proportion of different bacteria species which can synthesize the toxin. The detected bacterial species essential for the synthesis of uremic retention solutes were then verified using the Human Microbiome Project database. Moreover, we defined the relative abundance of human toxin-generating enzymes as well as the possibility of the synthesis of a particular toxin by the human metabolism Our study presents a novel bioinformatics approach for the elucidation of the origin of both uremic retention solutes and uremic toxins and for searching for the most likely human microbiome producers of toxins that can be targeted and used for the therapy of adverse consequences of uremia.

Sarcopenia is frequent in cirrhosis and is associated with unfavorable outcomes. The role of the gut-liver-muscle axis in this setting has been poorly investigated. The aim of this study was to identify gut microbiota, metabolic and inflammatory signatures associated with sarcopenia in cirrhotic patients. Fifty cirrhotic patients assessed for the presence of sarcopenia by the quantification of muscle mass and strength were compared with age- and sex-matched controls. A multiomic anal., including gut microbiota composition and metabolomics, serum myokines and systemic and intestinal inflammatory mediators, was performed. The gut microbiota of sarcopenic cirrhotic patients was poor in bacteria associated with phys. function (Methanobrevibacter, Prevotella and Akkermansia), and was enriched in Eggerthella, a gut microbial marker of frailty. The abundance of potentially pathogenic bacteria, such as Klebsiella, was also increased, to the detriment of autochthonous ones. Sarcopenia was associated with elevated serum levels of pro-inflammatory mediators and of fibroblast growth factor 21 (FGF21) in cirrhotic patients. Gut microbiota metabolic pathways involved in amino acid, protein and branched-chain amino acid metabolism were up-regulated, in addition to ethanol, trimethylamine and dimethylamine production Correlation networks and clusters of variables associated with sarcopenia were identified, including one centered on Klebsiella/ethanol/FGF21/Eggerthella/Prevotella. Alterations in the gut-liver-muscle axis are associated with sarcopenia in patients with cirrhosis. Detrimental but also compensatory functions are involved in this complex network.

It has been postulated to participate in key physiol. processes such as neuronal plasticity, energy metabolism, and pancreatic β-cell insulin secretion and regulation. Recently, we reported the first selective GPR27 agonist, 2,4-dichloro-N-(4-(N-phenylsulfamoyl)phenyl)benzamide (pEC₅₀ 6.34, E_max 100%). Here, we describe the synthesis and structure-activity relationships of a series of new derivatives and analogs of 2,4-dichloro-N-(4-(N-phenylsulfamoyl)phenyl)benzamide. All products were evaluated for their ability to activate GPR27 in an arrestin recruitment assay. As a result, agonists were identified with a broad range of efficacies including partial and full agonists, showing higher efficacies than the lead compound 2,4-dichloro-N-(4-(N-phenylsulfamoyl)phenyl)benzamide. The most potent agonist was 4-chloro-2,5-difluoro-N-(4-(N-phenylsulfamoyl)phenyl)benzamide (pEC₅₀ 6.85, E_max 37%), and the agonists with higher efficacies were 4-chloro-2-methyl-N-(4-(N-phenylsulfamoyl)phenyl)benzamide (pEC₅₀ 6.04, E_max 123%), and 2-bromo-4-chloro-N-(4-(N-phenylsulfamoyl)phenyl)benzamide (pEC₅₀ 5.99, E_max 123%). Docking studies predicted the putative binding site and interactions of agonist 4-chloro-2-methyl-N-(4-(N-phenylsulfamoyl)phenyl)benzamide with GPR27. Selected potent agonists were found to be soluble and devoid of cellular toxicity within the range of their pharmacol. activity. Therefore, they represent important new tools to further characterize the (patho)physiol. roles of GPR27.
