This book is going to be very helpful for the post graduate scholars and the research scholars at the beginning of their research carrier and will help them in selection of their research projects if based on pyrazole moiety. This gives a brief outlook on the Pyrazole- a five membered heterocyclic ring and its importance from the chemistry as well as medicinal aspect. This includes general information, different synthetic procedures and medicinal activity of pyrazole bearing active compounds. The medicinal activity was described along with brief literature and the structure of the active compounds showing different biological activities viz., antimicrobial, anticancer, antiviral, antimalarial, anti-inflammatory and analgesic activities. And while discussing the medicinal activity of different compounds containing pyrazole nucleus we have given the structures of starting materials as well which makes this book a unique and different from others. We hope our readers will find this book as an introductory tool in designing the new molecules and will be of widespread use which will further help in learning and become a reference for the medicinal chemist.This book is going to be very helpful for the post graduate scholars and the research scholars at the beginning of their research carrier and will help them in selection of their research projects if based on pyrazole moiety.
