Integrating synthetic accessibility with AI-based generative drug design

open access: yesJournal of Cheminformatics, 2023
Generative models are frequently used for de novo design in drug discovery projects to propose new molecules. However, the question of whether or not the generated molecules can be synthesized is not systematically taken into account during generation ...

Stochastic model for cell polarity

open access: yes, 2012
Cell polarity refers to the spatial asymmetry of molecules on the cell membrane. Altschuler, Angenent, Wang and Wu have proposed a stochastic model for studying the emergence of polarity in the presence of feedback between molecules.

Rapid determination of apolipoprotein E genotype using a heteroduplex generator

open access: yesJournal of Lipid Research, 1999
The apoE gene exhibits two common polymorphisms that have been associated with both coronary artery disease and Alzheimer's disease. The polymorphisms create the three allelic isoforms E2, E3, and E4 which are encoded by Cys–Cys, Cys–Arg, and Arg–Arg at ...

Net Electron Capture in Collisions of Multiply Charged Projectiles with Biologically Relevant Molecules

open access: yesAtoms, 2020
A model for the description of proton collisions from molecules composed of atoms such as hydrogen, carbon, nitrogen, oxygen and phosphorus (H, C, N, O, P) was recently extended to treat collisions with multiply charged ions with a focus on net ...

The octet rule in chemical space: Generating virtual molecules

open access: yes, 2017
We present a generator of virtual molecules that selects valid chemistry on the basis of the octet rule. Also, we introduce a mesomer group key that allows a fast detection of duplicates in the generated structures. Compared to existing approaches, our

Efficiency of Energy Transduction in a Molecular Chemical Engine

open access: yes, 2006
A simple model of the two-state ratchet type is proposed for molecular chemical engines that convert chemical free energy into mechanical work and vice versa. The engine works by catalyzing a chemical reaction and turning a rotor.

Drug transport mechanism of P-glycoprotein monitored by single molecule fluorescence resonance energy transfer

open access: yes, 2011
In this work we monitor the catalytic mechanism of P-glycoprotein (Pgp) using single-molecule fluorescence resonance energy transfer (FRET). Pgp, a member of the ATP binding cassette family of transport proteins, is found in the plasma membrane of animal
