The alkylating potential of beta-propiolactone (BPL), beta-butyrolactone (BBL), gamma-butyrolactone, and delta-valerolactone, which can be formed by the in vivo nitrosation of primary amino acids, was investigated kinetically. The nucleophile NBP, 4-(p-nitrobenzyl)pyridine, a trap for alkylating agents, was used as an alkylation substrate. The alkylation reactions were performed under mimicked ...
Simple primary-tertiary diamines easily derived from natural primary amino acids were used to catalyze the Michael addition of ketones with isatylidenemalononitrile derivatives. Diamine 1a in combination with D-CSA as an additive provided Michael adducts in high yield (up to 94%) and excellent enantioselectivity (up to 99%). The catalyst 1a was successfully used to catalyze the three-component ...
DNA-binding proteins play pivotal roles in alternative splicing, RNA editing, methylating and many other biological functions for both eukaryotic and prokaryotic proteomes. Predicting the functions of these proteins from primary amino acids sequences is becoming one of the major challenges in functional annotations of genomes. Traditional prediction methods often devote themselves to extracting...
Pancytopenia in childhood can be caused by a variety of underlying diseases including hematological and non-hematological entities. Phenylketonuria (PKU) is an inborn error of phenylalanine metabolism. No association between PKU and pancytopenia has ever been reported. We report the first case of PKU revealed by a pancytopenia at presentation. The patient was an infant girl born to healthy non-...
BACKGROUND The sustainable production of biofuels remains one of the major issues of the upcoming years. Among the number of most desirable molecules to be produced, butanol and isobutanol deserve a prominent place. They have superior liquid-fuel features in respect to ethanol. Particularly, butanol has similar properties to gasoline and thus it has the potential to be used as a substitute for ...
Aim. To analyze the effect of L-proline accumulation on chlorophyll content in transgenic wheat plants with a double-stranded RNA suppressor proline dehydrogenase gene under physiological and stress conditions. Methods. Agrobacterium-mediated transformation planta; biochemical determination free content; spectrophotometric photosynthetic pigments mathematical statistics. Results. It was shown t...
The SARS-CoV-2 virus has been responsible for a global pandemic which caused millions of deaths. Still, novel antiviral agents have investigated against SARS-CoV-2. In this view, molecular docking simulations could be used evaluating possible to tested in further experimental runs. Hence, the aim research was evaluate interaction dihydromyricetin DHM Spike glycoproteins pristine and its Delta O...
The objective of this study was to investigate the single dose antioxidant and antidiabetic effect of a herbomineral amino acid extract (HMAA) of Spinacia oleracea on alloxan induced diabetic rats. In the present study, the animals were divided into 6 groups: Group 1 – Normal saline as vehicle –control, Group 2 – Untreated diabetic rats (Alloxan induced), Group 3 – Animals treated with Metformi...
