Machine Learning Predicts Drug Metabolism and Bioaccumulation by Intestinal Microbiota

open access: yesPharmaceutics, 2021
Over 150 drugs are currently recognised as being susceptible to metabolism or bioaccumulation (together described as depletion) by gastrointestinal microorganisms; however, the true number is likely higher.

Relative Stability of Pyrazinamide Polymorphs Revisited: A Computational Study of Bending and Brittle Forms Phase Transitions in a Broad Temperature Range

open access: yesCrystals, 2023
Pyrazinamide may exist in at least four known polymorphic forms, which were obtained experimentally. One of these polymorphs, (α), shows outstanding mechanical properties, demonstrating a significant anisotropic plasticity in a three-point bending test ...

Compressed Oxygen in Drug Stability Experiments

open access: bronzeChemical and Pharmaceutical Bulletin, 2007
A drug stability experiment accelerated by compressed oxygen was established. The stability of 10% ascorbic acid solution as a model was studied and the kinetic parameters were obtained with the newly established experimental method. Because ascorbic acid degrades under both anaerobic and aerobic conditions, the total rate constant k(total) can be ...

Nanocrystals of Poorly Soluble Drugs: Drug Bioavailability and Physicochemical Stability [PDF]

open access: yesPharmaceutics, 2018
Many approaches have been developed over time to counter the bioavailability limitations of poorly soluble drugs. With advances in nanotechnology in recent decades, science and industry have been approaching this issue through the formulation of drugs as nanocrystals, which consist of pure drugs and a minimum of surface active agents required for ...

Hydrogen-bonded multilayer thin films and capsules based on poly(2-n-propyl-2-oxazoline) and tannic acid : investigation on intermolecular forces, stability, and permeability [PDF]

open access: yes, 2019
In recent years, hydrogen-bonded multilayer thin films and capsules based on neutral and nontoxic building blocks have been receiving interest for the design of stimuli-responsive drug delivery systems and for the preparation of thin-film coatings ...

Adaptive HIV-1 evolutionary trajectories are constrained by protein stability [PDF]

open access: yes, 2017
Despite the use of combination antiretroviral drugs for the treatment of HIV-1 infection, the emergence of drug resistance remains a problem. Resistance may be conferred either by a single mutation or a concerted set of mutations.
