Over the past few years, remarkable progress has been made in the development of human immunodeficiency virus (HIV) membrane fusion inhibitors. The focus has been on peptide inhibitors, which were developed by mimicking HIV sequences; however, these types of inhibitors generally lack oral bioavailability and are expensive. Therefore, development of small-molecule inhibitors has gained importance and recently progressed. This paper reviews the rapid advancements in the development of small-molecule HIV inhibitors over the last decade.
