Three new 5-fluoro-2- methylthio substituted pyrimidine derivatives have been synthesized and characterized by ¹H NMR spectroscopy and Mass spectrometry. Corrosion inhibition characteristics of the synthesized pyrimidine derivatives have been studied on mild steel (MS) in 0.5 M hydrochloric acid solution at various temperatures (303-333 K) using mass loss and electrochem. techniques.

Improving the binding affinity of a chem. series by systematically probing one of its exit vectors is a medicinal chem. activity that can benefit from mol. modeling input. Herein, the authors compare the effectiveness of four approaches in prioritizing building blocks with better potency: selection by a medicinal chemist, manual modeling, docking followed by manual filtering, and free energy calculations (FEP). The authors’ study focused on identifying novel substituents for the apolar S2 pocket of cathepsin L and was conducted entirely in a prospective manner with synthesis and activity determination of 36 novel compounds The authors found that FEP selected compounds with improved affinity for 8 out of 10 picks compared to 1 out of 10 for the other approaches. From this result and other addnl. analyses, the authors conclude that FEP can be a useful approach to guide this type of medicinal chem. optimization once it has been validated for the system under consideration.

Abstract: Interpersonal difficulties are often observed in major depressive disorder (MDD), while the underlying psychol. and biol. mechanisms have not yet been elucidated. In the present case-control study, a PC-based trust game was conducted for 38 drug-free MDD patients and 38 healthy controls (HC). In the trust game, participants invested money in a partner (trusting behaviors), and also rated each partners attractiveness (preference for others). In addition, blood biomarkers including metabolites were measured. Both MDD and HC males exhibited more trusting behaviors compared to females. MDD males preference for ordinary-attractive partners (lay-person photographs) was lower than HC males, whereas their preference for high-attractive females (fashion-model photographs) was similar levels to HC males. This tendency in MDD males could reflect a “focused (narrowed) preference for females”. As for blood biomarker anal., the levels of 37 metabolites including acetylcholine, AMP, GMP, nicotinic acid and tryptophan were significantly different between two groups. Interestingly, among male participants, acetylcholine and nicotinic acid were neg. correlated with the level of focused preference for photographed females. In sum, we have revealed some behavioral, psychol. and biol. traits of trusting behaviors and preference for others especially in MDD males. Larger studies should be conducted to validate our preliminary findings.

Formula: C5H4N2O4, Orotic acid anhydrous is a hydrogen bonding interaction that can be found in biological systems. It plays a role in the physiological effects of orotic acid, which is a metabolite of uridine and an intermediate in the synthesis of pyrimidine nucleotides. Orotic acid has antimicrobial properties and has been shown to inhibit enzyme activities involved in energy metabolism, such as polymerase chain reaction (PCR) and adenosine triphosphate (ATP) synthase. Orotic acid also inhibits the growth of bacteria, fungi, and parasites. Orotic acid anhydrous is used for treating myocardial infarcts or brain functions. The untreated group was given no treatment at all.
Orotic acid, also known as orotate or orotsaeure, belongs to the class of organic compounds known as pyrimidinecarboxylic acids. These are pyrimidines with a structure containing a carboxyl group attached to the pyrimidine ring. Orotic acid exists as a solid, slightly soluble (in water), and a moderately acidic compound (based on its pKa). Orotic acid has been found in human liver and pancreas tissues, and has also been primarily detected in saliva, feces, urine, and blood. Within the cell, orotic acid is primarily located in the cytoplasm and mitochondria. Orotic acid exists in all eukaryotes, ranging from yeast to humans. Orotic acid participates in a number of enzymatic reactions. In particular, Orotic acid can be biosynthesized from L-dihydroorotic acid and quinone; which is mediated by the enzyme dihydroorotate dehydrogenase (quinone), mitochondrial. In addition, Orotic acid and phosphoribosyl pyrophosphate can be converted into orotidylic acid through its interaction with the enzyme uridine monophosphate synthetase isoform a. In humans, orotic acid is involved in the pyrimidine metabolism pathway. Orotic acid is also involved in several metabolic disorders, some of which include the mngie (mitochondrial neurogastrointestinal encephalopathy) pathway, dihydropyrimidinase deficiency, UMP synthase deficiency (orotic aciduria), and Beta ureidopropionase deficiency. Outside of the human body, orotic acid can be found in a number of food items such as green vegetables, alaska blueberry, chickpea, and colorado pinyon. This makes orotic acid a potential biomarker for the consumption of these food products. Orotic acid is a potentially toxic compound. Orotic acid has been found to be associated with several diseases known as phosphoenolpyruvate carboxykinase deficiency 1, cytosolic and hyperornithinemia-hyperammonemia-homocitrullinuria; orotic acid has also been linked to several inborn metabolic disorders including n-acetylglutamate synthetase deficiency, lysinuric protein intolerance, and ornithine transcarbamylase deficiency.
Orotic acid appears as white crystals or crystalline powder.
Orotic acid is a pyrimidinemonocarboxylic acid that is uracil bearing a carboxy substituent at position C-6. It has a role as a metabolite, an Escherichia coli metabolite and a mouse metabolite. It derives from a uracil. It is a conjugate acid of an orotate., 65-86-1.
