Sulfonamide derivatives serve as an important building blocks in the drug design discovery and development (4D) process. Ciprofloxacin-, sulfadiazine- and amantadine-based sulfonamides were synthesized as potent inhibitors of jack bean urease and free radical scavengers. Molecular diversity was explored and electronic factors were also examined. All 24 synthesized compounds exhibited excellent potential against urease enzyme. Compound 3e (IC50 = 0.081 ± 0.003 µM), 6a (IC50 = 0.0022 ± 0.0002 µM), 9e (IC50 = 0...

Impulse control disorders (ICDs), such as compulsive gambling, buying, sexual, and eating behaviors, are a serious and increasingly recognized complication in Parkinson's disease (PD), occurring in up to 20% of PD patients over the course of their illness. Related behaviors include punding (stereotyped, repetitive, purposeless behaviors), dopamine dysregulation syndrome (DDS) (compulsive medication overuse), and hobbyism (e.g., compulsive internet use, artistic endeavors, and writing). These disorders have a significant impact on quality of life and function, strain interpersonal relationships, and worsen caregiver burden, and are associated with significant psychiatric comorbidity...

Here, we developed stable supramolecular binary vesicles on the basis of the host-guest interaction between β-cyclodextrins (β-CDs) and paclitaxel (PTX) dimer. The inclusion complexation between PTX dimer and β-CDs in water was studied by proton nuclear magnetic resonance spectroscopy and two-dimensional rotating-frame Overhauser effect spectroscopy. The resulting inclusion complex was amphiphilic and could self-assemble into vesicles with average diameter of 230 nm. The vesicles could evolve to nanoparticles (NPs) by adding competitive binding guest amantadine hydrochloride or by digesting β-CDs through α-amylase...

We report the case of a 36-year-old woman with a subarachnoid haemorrhage (SAH) caused by a rupture of a right-sided middle cerebral artery aneurysm and subsequent malignant infarction of the right hemisphere leading to a persistent vegetative state and severe spastic tetraparesis with recurrent myocloni. Nine months after disease onset, the patient was transferred to our department for diagnostic and therapeutic re-evaluation. The poor clinical condition could not be explained by the brain lesion caused by the SAH or infarction...

Tardive dyskinesia (TD) occurs in patients receiving antipsychotic treatment with dopamine receptor antagonists. Despite the prevalence of TD and its negative impact on patients' lives, there has been a lack of approved treatments and limited evidence from controlled trials of pharmacological treatment. Areas covered: PubMed was searched for English-language papers published during 2007-2016 using terms 'tardive dyskinesia' or 'drug-induced movement disorder', and 'treatment'. Studies evaluating pharmacological agents for the treatment of TD were selected...

A newly emerged H5N8 influenza virus was isolated from green-winged teal in Egypt during December 2016. In this study, we provide a detailed characterization of full genomes of Egyptian H5N8 viruses and some virological features. Genetic analysis demonstrated that the Egyptian H5N8 viruses are highly pathogenic avian influenza viruses. Phylogenetic analysis revealed that the genome of the Egyptian H5N8 viruses was related to recently characterized reassortant H5N8 viruses of clade 2.3.4.4 isolated from different Eurasian countries...

Influenza A viruses with the presence of mutations in M2 still circulate and threaten to avian species and human in China. A novel M2 inhibitor pinanamine was previously identified as an antiviral agent by an in vitro assay. In this study, we monitored the activity of pinanamine against influenza A/FM1/47 (H1N1) virus infection in cell culture and mice. Pinanamine showed more potent antiviral effect than ribavirin, and was as effective as oseltamivir carboxylate and amantadine in Madin-Darby canine kidney (MDCK) cells...

Influenza A viruses (IAVs) are endemic in swine and represent a public health risk. However, there is limited information on the genetic diversity of swine IAVs within farrow-to-wean farms, which is where most pigs are born. In this longitudinal study, we sampled 5 farrow-to-wean farms during a year and collected 4,190 individual nasal swabs from three distinct pig subpopulations. 207 (4.9%) samples tested PCR positive for IAV, and 124 IAVs were isolated. We sequenced the complete genome of 123 IAV isolates, and found 31 H1N1, 26 H1N2, 63 H3N2 and 3 mixed IAVs...

Amantadine is frequently used in addition to dopaminergic substances like dopamine agonists or L-Dopa in advanced Parkinson disease (PD). However, adverse effects like hallucinations limit its use. PD patients developing severe psychotic symptoms upon treatment with either dopaminergic substances and/or amantadine need to stop intake of any psychotropic substance. Here, we report the case of a 71-year-old PD patient without previously known cognitive impairment. He presented with drug-induced psychotic symptoms due to changes in his therapeutic regimen (increase in COMT inhibitors, newly introduced MAO B inhibitors)...
