Ariel Fernandez is an Argentinian-American physical chemist who held the Karl F. Hasselmann Professorship of Bioengineering at Rice University until 2011.[1] He was born in Bahía Blanca, Argentina in 1957 and is currently involved in technology development at the / Morgridge Institute for Research in Madison, Wisconsin, where he has been named Distinguished Investigator. In his native Argentina, Ariel Fernandez has been appointed Principal Investigator at I. A. M. (Instituto Argentino de Matematica) in Buenos Aires. Formally trained as a mathematician, he earned a Ph. D. in chemical physics from Yale University in 1984 and pursued his research endeavors in Goettingen under the tutelage of Nobel laureate Manfred Eigen. His widely acclaimed research spans various areas of algebra (representation theory), physical chemistry, molecular biophysics, dehydron physics and more recently, molecular evolution and drug discovery. In the latter field he pioneered the so-called wrapping technology and outlined this therapeutic paradigm in his book "Transformative Concepts for Drug Design: Target Wrapping".[2] Target wrapping introduces a new binding mode and a selectivity filter to broaden the universe of molecular prototypes while tightening the drug-discovery funnel by generating compounds capable of withstanding long-term attrition.
Ariel Fernandez's wrapping technology enables selectivity control in molecular targeted therapy and hinges on a pivotal concept: the dehydron. A dehydron is a structural singularity in a protein target, consisting of an intramolecular hydrogen bond incompletely shielded from water attack, thereby endowed with a propensity to promote its own dehydration. The dehydron pattern of a target protein is not conserved across other proteins with common ancestry, hence this pattern constitutes a selectivity filter for drug design. Thus, Ariel Fernandez pioneered the exploitation of evolutionary insights to enhance the safety and efficacy of molecular targeted therapy.
