Xenobiology is an emerging area of synthetic biology that aims to safeguard genetically engineered cells by storing synthetic biology information in xeno-nucleic acid polymers (XNAs). Critical to the success of this effort is the need to establish cellular systems that can maintain an XNA chromosome in actively dividing cells. This viewpoint discus...
Chemically modified genes and genomes with customized properties will become a valuable tool in numerous fields, including synthetic biology, biotechnology, and medicine. These genetic materials are meant to store and exchange information with DNA and RNA while tuning their functionality. Herein, we outline the development of an alternative genetic...
The recent outbreaks of Zika virus (ZIKV) infection worldwide make the discovery of novel antivirals against flaviviruses a research priority. This work describes the identification of novel inhibitors of ZIKV through a structure-based virtual screening approach using the ZIKV NS5-MTase. A novel series of molecules with a carbazoyl-aryl-urea struct...
Previously, we reported the discovery of 3,6-disubstituted isothiazolo[4,3-b]pyridines as potent and selective cyclin G-associated kinase (GAK) inhibitors with promising antiviral activity. In this manuscript, the structure-activity relationship study was expanded to synthesis of isothiazolo[4,3-b]pyridines with modifications of the pyridine moiety...
In the present study, an in vitro-in vivo extrapolation of dissolution integrated to a physiologically based pharmacokinetics modeling approach, considering a product-specific particle size distribution and a self-buffering effect of the drug, is introduced and appears to be a promising translational modeling strategy to support drug product develo...
HIV-1 reverse transcriptase (RT) is an essential enzyme, targeting half of approved anti-AIDS drugs. While nucleoside RT inhibitors (NRTIs) are DNA chain terminators, the nucleotide-competing RT inhibitor (NcRTI) INDOPY-1 blocks dNTP binding to RT. Lack of structural information hindered INDOPY-1 improvement. Here we report the HIV-1 RT/DNA/INDOPY-...
Currently significant efforts are devoted to designing small molecules able to bind selectively to guanine-quadruplexes (G4s). These non-canonical DNA structures are implicated in various important biological processes and have been identified as potential targets for drug development. Previously, we reported a series of triphenylamine(TPA)-based c...
Sea anemones' venom is rich in peptides acting on different biological targets, mainly on cytoplasmic membranes and ion channels. These animals are also a source of pancreatic α-amylase inhibitors, which have the ability to control the glucose level in the blood and can be used for the treatment of prediabetes and type 2 diabetes mellitus. Recently...
Hemagglutinin is the surface protein of the influenza virus that mediates both binding and penetration of the virus into host cells. We here report on the synthesis and structure-activity relationship of some novel N-(1-thia-4-azaspiro[4.5]decan-4-yl)-carboxamide compounds carrying the 5-chloro-2-methoxybenzamide structure, designed as influenza vi...

Theranostics involves finding the biomarkers of a disease, fighting them through site specific drug delivery and following them for prognosis of the disease. Microneedle array technology has been used for drug delivery and extended for continuous monitoring of analytes present in the skin compartment. We envisage the use of microneedle arrays for f...
