Possible Interference in Protein - Protein interaction as a new approach in microinhibition of respiratory pathogens on nasal- oral epithelium: An early on-screen study with reference toSARS-Cov-2-ACE2 binding interference

ABSTRACT

Upper and lower respiratory pathogens - both microbes and viruses -are responsible for very high morbidity, man-hour loss, residual long term clinical conditions and even mortality. In india only, high incidence of annual respiratory infections - both UT and LT - demands prophylactic intervention in addition to all therapeutic interventions available.The issue of respiratory infections is more pronounced now in the backdrop of nearly uncontrolled high incidences of SARS-Cov-2 affection resulting in death and damage of human lives to the extent of hundreds of millions spreading over entire world, with incidence variations from country to country. After the initial unanswered phase of spread of SARS-Cov-2 virus with attendant unseen mortalities, quickest invention of a series of unusual vaccines have stemmed the lethal progress to a very significant extent, although vaccinating each and every human subject - nearly 8 to 9 bn in supremely divided world -economically-- is an unthinkable proposition where economic disparity dictates vaccine availability and implementation.Moreover, being of highly unstable nucleic acid composition, the original virus, by now has a thick set of variants around the globe with variable clinical outcome. Given this complex background of scanty availability and inefficient implementation, there always is a need of a preventive approach which can possibly micro-fix the pathogens, including SARS-2 on nasal epithelium so as to interfere with viral [or any pathogen] entry through specified receptor gate[s] or any other ways. The present formulation is under study -- as a candidate of interference on nasal / oral mucosa for all respiratory pathogens. This brief report describes dry on-screen studies of protein - protein interaction as well as its possible interference by an amino acid Lysine. Phospholipid bilayerresponses in presence of added loads of the same essential amino acid -Lysine - showed unusual and unexplained behavior both in structural integrity as well in spatial orientation.
