This Research Topic will honor Prof. M. Iqbal Choudhary for his pioneering contribution in the field of Bioorganic, Synthetic, and Natural Product Chemistry. Prof. M. Iqbal Choudhary is Director and Professor of Bioorganic and Natural Product Chemistry at the International Center for Chemical and Biological Sciences (H. E. J. Research Institute of Chemistry and Dr. Panjwani Center for Molecular Medicine and Drug Research), Pakistan and Coordinator General COMSTECH. Since 1990, Prof. Choudhary has been among the world leaders in the field of natural product chemistry, and has made pioneering contributions in the discovery of novel natural products. Prof. Choudhary has 1,212 publications (cumulative impact of > 2500) with 33,550 citations (h index 76) in the fields of organic and bioorganic chemistry. He also published 94 patents (64 US Patents), 90 books and 40 chapters in books, published by major U.S. and European presses. He discovered many potent anti-epileptic and anti-leishmanial compounds from indigenous medicinal plants that are under clinical trials. His contributions to reverse bacterial resistance to antibiotics represent seminal contributions in this important field. He has trained hundreds of young researchers, especially women, from across the Afro-Asian region in natural product chemistry and established several research centers in Pakistan, and helped to setup research units in Africa, and South and Central Asia. His scientific contributions have been recognized by prestigious national and international awards and honors, and fellowships of several academies of science.
