TLDR
In this article, the Universal Force Field (UFF) was used to predict the structures of a variety of organic molecules, including unstrained and uncongested hydrocarbons, silanes, alkenes, saturated amines, saturated ethers and phosphines.
Abstract
The application of a Universal force field (UFF) to the treatment of organic molecules is described. The ability of the force field to predict the structures of a variety of organic molecules is examined, and the results are compared with the MM2 or MM3 force fields. UFF correctly predicts the structures of unstrained and uncongested hydrocarbons, silanes, alkenes, saturated amines, saturated ethers and phosphines, aromatic systems, and simple unconjugated multiple bond containing compounds such as nitriles, ketones, and imines well

Binding site of activators of the cystic fibrosis transmembrane conductance regulator in the nucleotide binding domains

TL;DR: Comparison of theoretical binding free energy estimates in the model to free energy estimated from the apparent dissociation constants, KD, resulted in a remarkably good correlation coefficient for one of the putative binding sites, located in the interface between NBD1 and NBD2.

A GROMOS-Compatible Force Field for Small Organic Molecules in the Condensed Phase: The 2016H66 Parameter Set

TL;DR: This article reports on the calibration and validation of a new GROMOS-compatible parameter set 2016H66 for small organic molecules in the condensed phase, based on 62 organic molecules spanning the chemical functions alcohol, ether, aldehyde, ketone, carboxylic acid, ester, amine, amide, thiol, sulfide, and disulfide, as well as aromatic compounds and nucleic-acid bases.
