A novel series of pyrimidine derivatives, bearing modified benzimidazoles at N-1 position, has been designed, synthesized and screened as NNRTIs against HIV and as broad-spectrum antiviral agents. The molecules were screened against different HIV targets using molecular docking experiment. The docking results indicated that the molecules interacted...

Epidermal growth factor receptor (EGFR) is a transmembrane protein tyrosine kinase that is usually overexpressed in many types of cancers. In the present study, an effort was done in synthesis of new 3,4-diaminothieno[2,3-b] thiophene-2,5-dicarbonitrile derivatives 2-8, assisted by a microwave device. Different spectroscopic instruments were used f...
Upregulated CXCR2 signalling is found in numerous inflammatory, autoimmune and neurodegenerative diseases, as well as in cancer. Consequently, CXCR2 antagonism is a promising therapeutic strategy for treatment of these disorders. We previously identified, via scaffold hopping, a pyrido[3,4-d]pyrimidine analogue as a promising CXCR2 antagonist with ...
Following on our initial discovery of S-CN-DABOs as non-nucleoside reverse transcriptase inhibitors (NNRTIs), a series of novel S-N3-DABO derivatives F1-F31 were developed by substituting the cyano group of S-CN-DABOs with azide group. Some of these compounds were conferred significantly increased potency against wild-type HIV-1 and clinically obse...
Herein, via crystallographic overlay-based molecular hybridization strategy, a series of disubstituted pyrimidine-5-carboxamide derivatives were designed by introducing an amide moiety to the central core of the lead etravirine. All the newly synthesized compounds were evaluated for their anti-HIV-1 potencies in MT-4 cells using the MTT method. Mos...
Microtubule (MT)-stabilizing 1,2,4-triazolo[1,5-a]pyrimidines (TPDs) hold promise as candidate therapeutics for Alzheimer's disease (AD) and other neurodegenerative conditions. However, depending on the choice of substituents around the TPD core, these compounds can elicit markedly different cellular phenotypes that likely arise from the interactio...
BackgroundAtopic dermatitis is a chronic inflammatory skin disease that can negatively impact work productivity and daily activities. Ruxolitinib cream, a Janus kinase inhibitor, demonstrated efficacy and safety in patients with atopic dermatitis in two phase III studies (TRuE-AD1 and TRuE-AD2).ObjectiveThis post hoc analysis sought to describe the...
DksA is a conserved RNA polymerase-binding protein known to play a key role in the stringent response of proteobacteria species, including many gastrointestinal pathogens. Here, we used RNA-sequencing of Escherichia coli, Salmonella bongori and Salmonella enterica serovar Typhimurium, together with phenotypic comparison to study changes in the DksA...
BackgroundPathogenic gain of function variants in Valosin-containing protein (VCP) cause a unique disease characterized by inclusion body myopathy with early-onset Paget disease of bone and frontotemporal dementia (also known as Multisystem proteinopathy (MSP)). Previous studies in drosophila models of VCP disease indicate treatment with VCP inhibi...
A series of dipicolyl amine pyrimidines (DPPs) were previously identified as potential α7 agonists by means of a calcium influx assay in the presence of the positive allosteric modulator (PAM) 1-(5-chloro-2,4-dimethoxy-phenyl)-3-(5-methyl-isoxazol-3-yl)-urea (PNU-120596). The compounds lack the quaternary or strongly basic nitrogens of typical nico...
