Enzymes are excellent catalysts that are increasingly being used in industry and academia. This Perspective provides a general and practical guide to enzymes and their synthetic potential, primarily aimed at synthetic organic chemists.

The human immunodeficiency virus (HIV) causes AIDS (acquired immune deficiency syndrome), a disease in which the immune system progressively deteriorates, making sufferers vulnerable to all manner of opportunistic infections. Currently, world-wide there are estimated to be 34 million people living with HIV, with the vast majority of these living in sub-Saharan Africa. Therefore, an important research focus is development of new drugs that can be used in the treatment of HIV/AIDS. This review gives an overview of the disease and addresses the drugs currently used for treatment, with specific emphasis on new developments within the class of allosteric non-nucleoside reverse transcriptase inhibitors (NNRTIs).
