摘要:
Described herein are nanoparticles which are largely made of (e.g., 90 wt.%) hydrophobic drugs and are stabilized by water soluble dyes. The nanoparticles can range in size from 30 nm to 150 nm and have highly negative surface charge (e.g., -55mV). These nanoparticles are highly soluble in water, stable for days in PBS buffer and can be easily lyophilzed and reconstituted in water. Using quantitative self-assembly prediction calculations, topochemical molecular descriptors were identified and validated as highly predictive indicators of nano-assembly, nanoparticle size, and drug loading. The resulting nanoparticles selectively targeted kinase inhibitors to caveolin-1-expressing human colon cancer and autochthonous liver cancer models to yield striking therapeutic effects while avoiding pERK inhibition in healthy skin. The nanoparticles exhibited remarkable anti-tumor efficacy in vitro and in vivo in models of hepatocellular carcinoma.
摘要:
Systems and methods for discovery and characterization of neuroactive drugs are provided. In some aspects, a method for evaluating an effectiveness of a drug administered to a subject includes receiving neurophysiological data acquired from a subject under an administration of a drug, and analyzing the neurophysiological data to generate signatures indicative of brain states induced by the drug. The method also includes correlating the generated signatures with a database comprising information associated with a plurality of drug profiles, and determining, using the information, a molecular activity profile for the drug. The method further includes generating a report indicative of the effectiveness of the drug using the molecular activity profile.
摘要:
A method and system for determining the relative activation strength of drug molecules at G-Protein Coupled Receptors (GCPR) are presented herein. The method and system involve the comparison the protein activation of members within a family of similar molecules, allowing for the selection of the best candidate for a specific protein-target.
摘要:
A method is disclosed for enhancing the simulation of the interaction between at least a first and a second molecular system, the interaction resulting from actual attraction and repulsion forces between the at least a first and a second molecular system. The method comprises applying an additional virtual electrostatic force between the at least a first and a second molecular system, which force has a functional form of the type of a modulated electrostatic interaction.

摘要:
La presente invención tiene su aplicación dentro del campo de dinámica molecular, la cual consiste en métodos de computación para la predicción de la estructura y función de biomoléculas, y en particular de proteínas, mediante la simulación de los procesos de plegamiento de las mismas y de interacción con otras biomoléculas en un solvente. Más particularmente, la invención se refiere a un método y un sistema de control de estabilidad de las simulaciones y de elección del paso de tiempo usado en la integración numérica de las ecuaciones del movimiento. La invención logra reducir el tiempo de simulación de la dinámica molecular mediante la optimización de la elección paso de tiempo a través de un control adaptativo o permitiendo pasos de tiempo mayores corrigiendo las trayectorias en base a un control de la potencia.
