NetInfer is a web server for prediction of targets and therapeutic and adverse effects via network-based inference methods. Compared with our previously developed standalone version of NetInfer, this web server provides a user-friendly interface. With the web server, users can easily predict potential target proteins, microRNAs, pathways, Anatomical Therapeutic Chemical (ATC) classification codes or adverse drug events (ADEs) for small molecules of their interests in a few steps. The prediction results may facilitate the discovery of new therapeutic and adverse effects for the user-submitted molecules, and help explain their molecular mechanisms.
★Prediction of target proteins
In recent years, based on our previously developed Network-Based Inference (NBI) method, we developed two improved methods for prediction of drug-target interactions (DTIs), namely substructure-drug-target NBI (SDTNBI) and balanced SDTNBI (bSDTNBI). These two methods can predict potential targets for various types of compounds, not only for approved drugs, but also for other natural and unnatural products in research and development. Compared with traditional methods such as structure-based methods and supervised machine learning, our NBI methods do not rely on three-dimensional structures of targets or negative samples. Using bSDTNBI in combination with in vitro assays, we identified new active compounds for several target proteins, including estrogen receptor α, prostaglandin E2 receptor EP4 subtype, and NAD(P)H:quinone oxidoreductase 1. These successful applications demonstrated the practical value of our NBI methods in target prediction.

★Prediction of microRNAs
Besides target proteins, NBI methods can also be used for prediction of microRNAs. In a previous study, we applied NBI to predict potential microRNAs for anticancer drugs, and validated several predicted drug-microRNA associations.

★Prediction of Pathways
In addition to target prediction, the applications of NBI methods can be further expanded to other types of prediction, by recognizing other prediction objects as special targets. For example, we applied bSDTNBI in prediction of pathways.

★Standalone version of NetInfer
Several years ago, we developed a standalone software named NetInfer via C++ programming language. The aforementioned network-based methods including NBI, SDTNBI and bSDTNBI were implemented in this program.
The first version of NetInfer is light weight and does not need the support of any third-party math libraries. Recently, we further improved it to accelerate the calculation. The NVIDIA cuBLAS library, an GPU-accelerated implementation of the basic linear algebra subroutines (BLAS), was used to accelerate the matrix computation such as matrix multiplication.
The latest version of NetInfer can be downloaded here. This binary executable file was compiled by GNU C++ compiler (version 4.8.5) with the support of NVIDIA CUDA toolkit (version 10.1), and has been tested on CentOS 7. The tutorials will be online soon.
★Online version of NetInfer
Although the standalone version of NetInfer provides a uniform platform for users to construct network-based models, evaluate model performance and perform prediction, there are still two limitations.Firstly, the software is just a command-line program. No graphic user interface was provided. Users need to type a long command line with many arguments to run it. Even small mistakes in the command line could lead to unexpected errors.
Secondly, the software requires users to store their network data in a specified format before using it. Users may need to write programs for format conversion.
These limitations make the software unfriendly to users, especially novice ones. To improve user experience, we developed the online version of NetInfer as a web server based on the standalone version. This web server was implemented using Apache, MariaDB and PHP.
