Natural Product Based Drug Discovery Against Human Parasites

Abstract

Protozoan-dependent ailments such as leishmaniasis, malaria and trypanosomiasis continue to be considered as the most neglected diseases, especially among economically deprived populations in developing sub-tropical and tropical belts of Asia, America and Africa. It is also known as the “disease of poverty” as most of the victims belong to the poorest communities. Among the prevalent protozoan parasitic diseases, leishmaniasis ranks second after malaria. Owing to toxicities and adverse effects as well as drug resistance to conventional treatment, new modalities for the treatment of parasitic infections are being continuously explored especially from naturally available bioactive compounds. These have impelled researchers to discover innovative medicines from natural biodiversity as alternative resources from marine environs that are economical, effective, and safe.

Marine environment is recognized with a variety of substances from the classes predominately from invertebrates including tunicates, sponges, bryozoans, molluscs marine cyanobacteria and bacteria, which targets many diseases including the three protozoan diseases mentioned above. As the diseases progress and develop resistance to current treatments, the marine world provides pioneering alternatives against parasitic diseases. The chapter explains the life cycle and geographical distribution of Leishmania, Malaria, and Trypanasoma and the novel marine metabolites that are being exploited for their anti-parasitic activity. Enhanced global awareness regarding the novel anti-infective remedies that are being explored from the incredible diversity of natural marine products will assimilate the augmented efforts to utilize marine products in clinical applications.
