MANAN 11 Zooceuticals – Promising Bio-molecules for Synthetic Simulation Dipan Adhikari*, Suman Mukherjee 1 , Tuhin Ghosh 2 Abstract: The terŵ ZooĐeutiĐal Đorroďorates the ďraŶĐh of sĐieŶĐe, whiĐh deals with the influence of drugs of zoological origin in pharmaceuticals. There are several medicines, which are used, now a days and its origin is from animals. Most of these drugs are proteinaceous. With the coming of sophisticated technologies to separate, characterize and mass produce proteins and peptides, the research on potent drugs of zoological origin is fast catching. The purpose of this paper is to shed some light on some of the most prominent molecules with the potential to be established as drugs in future. Most of these promising candidates have come from such as snake, bats, lizard, etc., and are often very potent and toxic in higher doses. Some other rare species like desert pupfish, which can be used to treat renal disease. The above is just a small fraction of what may be available in the nature. An attempt has been made to point out the importance of zoology in the field of pharmaceuticals. Key words: marine animals, saponins, sterols, steroids, sesquiterpenes, marine toxins Introduction Zooceuticals is an outcome of interdisciplinary research work in science, which deals with the influence and contribution of zoology on pharmaceutical sciences. The zoological world around us is abundant with many substances that hold promise for the treatment of numerous diseases and medical conditions. A huge potential zoological repository of drugs remains untapped since most research is being channelized, at least in India, only to exploitation of herbal medicines. Today 56% of top selling prescription drugs contain natural compounds found in the wild and derived from endangered animals. Zooceuticals are available which already shown silver lining in fighting cancer, heart diseases, AIDS and other dreaded illness [1] (Dreaded illness is a paramedical term/ phrase to implore the sudden occurrence of symptoms associated with cancer or AIDS or other deadly diseases which puzzle the medical practitioners, mainly immunosuppressions). Common belief is that only few of useful pharmaceuticals come from animal kingdom, viz; snake-anti venom, vitamin A/ D (shark/ cod liver oil) or excipients such as beeswax, spermaceti, lecithin or cochineal. However, in many laboratories worldwide, a plethora of diverse animals are being systematically investigated to extract useful drug candidates for multitude of therapeutic indications. Many of these drugs are proteins/ peptides in nature. With the coming of sophisticated technologies to separate, purify, characterize and the mass production of proteins and peptides, the research on drugs of zoological origin is fast catching up and may be in future provide the much needed breakthroughs in several deadly diseases. The purpose of this paper will be to shed some light on some _____________________________________________________________________________________ * Assistant Professor of Botany, Post-Graduate Dept of Botany, Hooghly Mohsin College, Chinsurah Email: dipanadhikari@gmail.com 1 Assistant Professor, Post Graduate Department of Zoology, A.
