In our present work, we emphasized on the potential of barbituric acid (1) derivatives as drugs like anti-bacterial, hypnotic, sedative, anti-microbial and antifungal agents. As naturally occurring, barbituric acid (1) is inactive but in the derivative form, it has a large number of medicinal uses and nowadays, it has a great demand in the pharmaceutical industry. Barbituric acid has a wide range of applications in the synthesis of a diverse class of compounds like heterocyclic, carbocyclic, synthetic alkaloids, and due to its broad-spectrum applications, barbituric acid acquired the position of building blocks in synthetic chemistry. Through the history of humanity, a number of bioactive agents have been applied to cure the disease related to hypnotics and sedatives, while the exact efficacy of these agents was found to be limited. Till now, review articles on barbituric acid only express their specific aspect but in present review article, all aspects are discussed in detail to provide a platform to readers and researchers so that they could obtain all information and background knowledge from a single point.

Objective: To determine the frequency of electrolyte disorders, i.e., serum sodium and potassium and to evaluate its effect on mortality rate among children admitted at the pediatric intensive care unit. Study Design and Setting: This was a descriptive cross sectional study conducted at Pediatric Intensive care unit of Civil Hospital Karachi from April to December 2017 Methodology: Informed consent was obtained from 150 parents of the children who fulfill the inclusion criteria. Laboratory data (serum sodium and serum potassium) were recorded during the stay in the pediatric intensive care unit. Data was analyzed using SPSS version 20. Mean ± S.D was calculated for quantitative variables. Frequency and percentage were calculated for gender, electrolyte disorders and mortality. Effect modifiers were controlled by stratification of age, gender and electrolyte disorders (Hypernatremia, Hyponatremia, Hyperkalemia, and Hypokalemia). Post-stratification, Chi-squared test was applied. P-value = 0.05 was taken as significant. Results: Out of 150 patients, electrolyte disorders in terms of serum sodium and potassium, were found in 86(57.3%) children. Mortality in children with electrolyte disorders was found to be 46(53.5%) which was significantly higher (P<0.001) than patients without electrolyte disorders 40(46.5%). Hypernatremia was found in 48(32%), hyponatremia 24(16%), hyperkalemia 21(14%) and hypokalemia in 42(28%) patients.In comparison; of electrolyte disorders with mortality; significant association was found in hypernatremia (P<0.001), and hyperkalemia (P<0.001). Conclusion: The most common electrolyte abnormalities were hypernatremia and hypokalemia. Mortality was significantly higher in subjects with electrolyte disorders, especially hypernatremia and hyperkalemia

Objective: In this study, small molecules possessing tetrahydropyrimidine derivatives have been synthesized having halogenated benzyl derivatives and carboxylate linkage. As previously reported, FDA approved halogenated pyrimidine derivatives prompted us to synthesize novel compounds in order to evaluate their biological potential. Methodology: Eight pyrimidine derivatives have been synthesized from ethyl acetoacetate, secondary amine, aromatic benzaldehyde by adding catalytic amount of CuCl2·2H2O via solvent less Grindstone multicomponent reagent method. Molecular structure reactivity and virtual screening were performed to check their biological efficacy as an anti-oxidant, anti-cancer and anti-diabetic agent. These studies were supported by in vitro analysis and QSAR studies. Results: After combined experimental and virtual screening 5c, 5g and 5e could serve as lead compounds, having low IC50 and high binding affinity.

In spite of phenobarbital has been used in various medical fields as hypnotics, anxiolytics, and anticonvulsants, it also contains active functional groups that can be reacted to form other products as dyes, polymers, antimicrobial and anti-antioxidants agents. A series of barbituric acid derivatives containing 1,2,3,4-Tetrazoline moiety were synthesized from phenobarbital. Phenobarbital 1 as raw starting material was reacted with acrylonitrile compound to give diacetonitrile derivative 2, this compound was treated in two ways, urea and thiourea to form barbituric acid derivatives containing oxadiazole and thiadiazole ring 3, 4 respectively. The Schiff bases derivatives 5, 6 (a-c) were synthesized from reacting the latter compounds with three aromatic aldehydes. In the final step, the barbituric acid derivatives containing 1,2,3,4Tetrazoline moiety 7, 8 (a-c) were prepared by cycloaddition reaction between different Schiff bases derivatives and sodium azide. The compounds were characterized by Melting point, 13 C-NMR, 1 H-NMR and FTIR techniques. Also, the result compounds were tested against two kinds of bacteria and two kinds of fungi. Most of the prepared derivatives were showed a high and clear effect against different types of bacteria and fungi. Molecular docking of final barbituric acid derivatives 7, 8 (a, b) were investigated with Molegro Virtual Docker (MVD).

Plant-derived compounds represent an important source for developing innovative drugs. One of the widely distributed plants, especially in Afghanistan and Pakistan, Seriphidium stenocephalum, was investigated in this study to identify bioactive compounds. The plant extract was subjected to silica gel column chromatography, four phenolic acid derivatives were isolated, while stenocephol was obtained by ethyl acetate fraction. Stenocephol was subjected to experimental screening for anti-diabetic and
