Challenges and Promises for Obtaining New Antiprotozoal Drugs: What’s Going Wrong?
Infections by protozoa can cause some of the most serious human diseases, particularly in tropical regions. However, the number of available drugs used to treat such diseases tends to be limited with relatively high toxicity, and the vast majority of such drugs were developed in the 1920s to 1970s. The development of antiprotozoal drugs has been hindered owing in part to: (1) the highly complicated life cycles of such organisms and their ability to avoid innate immune defences; (2) challenges associated with culturing such organisms particularly in different phases of their growth and amplification; and (3) a lack of investment in biomedical research aimed at developing treatments for tropical…

Human antiprotozoal therapy: past, present, and future
Human protozoal infections are ubiquitous and occur worldwide. In many cases, antiprotozoal agents currently in use predate the modern antibiotic era. Despite the relative lag in development of new antiprotozoal agents, the 1990s have witnessed an increasing level of interest in these infections, inspired by international travel and immigration, a growing awareness of antiprotozoal drug resistance, and the significance of acute and recrudescent protozoal infections in immunosuppressed hosts.
Recent Advances in the Discovery of Novel Antiprotozoal Agents
Diseases caused by protozoan parasites are responsible for considerable mortality and morbidity, affecting more than 500 million people worldwide. Globally, the burden of protozoan diseases is increasing and is been exacerbated because of a lack of effective medication due to the drug resistance and toxicity of current antiprotozoal agents. These limitations have prompted many researchers to search for new drugs against protozoan parasites.

Indeed, only three new drugs have entered into clinical trials in recent times, highlighting the tremendous gap in knowledge that should be bridged to more effectively treat protozoal infections.
